Having another day of a system administrator boredom, we had a task to upgrade some Tivoli TSM Backup clients running on a 20+ machines powered by CentOS and RHEL Linux to prepare the systems to be on the latest patched IBM Spectrum Backup client version available from IBM. For the task of patching I've used a central server where, I've initially downloaded the provided TSM client binaries archives. From this machine, we have copied TivSM*.tar to each and every system that needs to be patched and then patched. The task is not too complex as the running TSM in the machines are all at the same version and all running a recent patched version of Linux. Hence to make sure all works as expected we have tested TSM is upgraded from 7.X.X to 8.X.X on one machine and then test 8.1.8 to 8.1.11 upgrade on another one. Once having confirmed that Backups works as expected after upgrade. We have proceeded to do it massively on each of the rest 20+ hosts.
Below article's goal is to help some lazy sysadmin with the task to prepare an TSM Backup upgrade procedure to standartize TSM Upgrade, which as many of the IBM's softwares is very specific and its upgrade requires, a bit of manual work and extra cautious as there seems to be no easy way (or at least I don't know it), to do the upgrade by simply adding an RPM repository and doing, something like yum install tivsm*.


0. Check if there is at least 2G free of space

According to documentation the minimum space you need to a functional install without having it half installed or filling up your filesystem is 2 Gigabytes of Free Memory on a filesystem where the .tar and rpms will be living.

Thus check what is the situation with your filesystem where you wills store the .tar archice and extract .RPM files / install the RPM files.

# df -h

1. Download the correct tarball with 8.1 Client

On one central machine you would need to download the Tivoli you can do that via wget / curl / lynx whatever is at hand on the Linux server.

As of time of writting this article TSM's 8.1.11 location is at
URL:

http://public.dhe.ibm.com/storage/tivoli-storage-management/maintenance/client/v8r1/Linux/LinuxX86/BA/v8111/

I've made a local download mirror of Tivoli TSM 8.1.11 here.
In case you need to install IBM Spectrum Backup Client to a PCI secured environment to a DMZ-ed LAN network from a work PC you can Download it first from your local PC and via Citrix client upload program or WinSCP upload it to a central replication host from where you will later copy to each of the other server nodes that needs to be upgraded.

Lets Copy archive to all Server hosts where you want it later installed, using a small hack

Assuming you already have an Excel document or a Plain text document with all the IPs of the affected hosts where you will need to get TSM upgraded. Extract this data and from it create a plain text file /home/user/hosts.txt containing all the machine IPs lined up separated with carriage return separations (\n), so you can loop over each one and use scp to send the files.

– Replicate Tivoli tar to all machine hosts where you want to get IBM Spectrum installed or upgraded.
Do it with a loop like this:

# for i in $(cat hosts.txt); do scp 8.1.11.0-TIV-TSMBAC-LinuxX86.tar user@$i:/home/user/; done

 Copy to a Copy buffer temporary your server password assuming all your passwords to each machine are identical and paste your login user pass for each host to initiate transfer
 

2. SSH to each of the Machine hosts IPs

Once you login to the host you want to upgrade
Go to your user $HOME/home/user and create files where we'll temporary store Tivoli archive files and extract RPMs

[root@linux-server user]# mkdir -p ~/tsm/TSM_BCK/
[root@linux-server user]# mv 8.1.11.0-TIV-TSMBAC-LinuxX86.tar ~/tsm
[root@linux-server user]# cd tsm
[root@linux-server user]# tar -xvvf 8.1.11.0-TIV-TSMBAC-LinuxX86.tar
gskcrypt64-8.0.55.17.linux.x86_64.rpm
GSKit.pub.pgp
gskssl64-8.0.55.17.linux.x86_64.rpm
README_api.htm
README.htm
RPM-GPG-KEY-ibmpkg
TIVsm-API64.x86_64.rpm
TIVsm-APIcit.x86_64.rpm
TIVsm-BAcit.x86_64.rpm
TIVsm-BAhdw.x86_64.rpm
TIVsm-BA.x86_64.rpm
TIVsm-filepath-source.tar.gz
TIVsm-JBB.x86_64.rpm
TIVsm-WEBGUI.x86_64.rpm
update.txt

3. Create backup of old backup files

It is always a good idea to keep old backup files

[root@linux-server tsm]# cp -av /opt/tivoli/tsm/client/ba/bin/dsm.opt ~/tsm/TSM_BCK/dsm.opt_bak_$(date +'%Y_%M_%H')
[root@linux-server tsm]# cp -av /opt/tivoli/tsm/client/ba/bin/dsm.sys ~/tsm/TSM_BCK/dsm.sys_bak_$(date +'%Y_%M_%H')

[root@linux-server tsm]# [[ -f /etc/adsm/TSM.PWD ]] && cp -av /etc/adsm/TSM.PWD ~/TSM_BCK/ || echo 'file doesnt exist'

/etc/adsm/TSM.PWD this file is only there as legacy for TSM it contained encrypted passwords inver 7 for updates. In TSM v.8 encryption file is not there as new mechanism for sensitive data was introduced.
Be aware that from Tivoli 8.X it will return error
exist'

!! Note – if dsm.opt , dsm.sys files are on different locations – please use correct full path locations !!

4. Stop  dsmcad – TSM Service daemon

[root@linux-server tsm]# systemctl stop dsmcad

5. Locate and deinstall all old Clients

Depending on the version to upgrade if you're upgrading from TSM version 7 to 8, you will get output like.

[root@linux-server tsm]# rpm -qa | grep 'TIVsm-'
TIVsm-BA-7.1.6-2.x86_64
TIVsm-API64-7.1.6-2.x86_64

If you're one of this paranoid admins you can remove TIVsm packs  one by one.

[root@linux-server tsm]# rpm -e TIVsm-BA-7.1.6-2.x86_64
[root@linux-server tsm]# rpm -e TIVsm-API64-7.1.6-2.x86_64

Instead if upgrading from version 8.1.8 to 8.1.11 due to the Security CVE advisory recently published by IBM e.g. (IBM Runtime Vulnerability affects IBM Spectrum Backup archive Client) and  vulnerability in Apache Commons Log4J affecting IBM Spectrum Protect Backup Archive Client.

[root@linux-server tsm]# rpm -qa | grep 'TIVsm-'
TIVsm-API64-8.1.8-0.x86_64
TIVsm-BA-8.1.8-0.x86_64

Assuming you're not scared of a bit automation you can straight do it with below one liner too 🙂

# rpm -e $(rpm -qa | grep TIVsm)

[root@linux-server tsm]# rpm -qa | grep gsk
[root@linux-server tsm]# rpm -e gskcrypt64 gskssl64

6. Check uninstallation success:

[root@linux-server tsm]# rpm -qa | grep TIVsm
[root@linux-server tsm]# rpm -qa | grep gsk

Here you should an Empty output, if packages are not on the system, e.g. Empty output is good output ! 🙂

7. Install new client IBM Spectrum Client (Tivoli Storage Manager) and lib dependencies

[root@linux-server tsm]# rpm -ivh gskcrypt64-8.0.55.4.linux.x86_64.rpm
[root@linux-server tsm]# rpm -ivh gskssl64-8.0.55.4.linux.x86_64.rpm

 If you're lazy to type you can do as well

[root@linux-server tsm]# rpm -Uvh gsk*

Next step is to install main Tivoli SM components the the API files and BA (The Backup Archive Client)

[root@linux-server tsm]# rpm -ivh TIVsm-API64.x86_64.rpm
[root@linux-server tsm]# rpm -ivh TIVsm-BA.x86_64.rpm

If you have to do it on multiple servers and you do it manually following a guide like this, you might instead want to install them with one liner.

[root@linux-server tsm]# rpm -ivh TIVsm-API64.x86_64.rpm TIVsm-BA.x86_64.rpm

There are some Not mandatory "Common Inventory Technology" components (at some cases if you're using the API install it we did not need that), just for the sake if you need them on your servers due to backup architecture, install also below commented rpm files.

## rpm -ivh TIVsm-APIcit.x86_64.rpm

## rpm -ivh TIVsm-BAcit.x86_64.rpm

These packages not needed only for operation WebGUI TSM GUI management, (JBB) Journal Based Backup, BAhdw (the ONTAP library)


— TIVsm-WEBGUI.x86_64.rpm
— TIVsm-JBB.x86_64.rpm
— TIVsm-BAhdw.x86_64.rpm

8. Start and enable dsmcad service

[root@linux-server tsm]# systemctl stop dsmcad

You will get

##Warning: dsmcad.service changed on disk. Run 'systemctl daemon-reload' to reload units.

[root@linux-server tsm]# systemctl daemon-reload

[root@linux-server tsm]# systemctl start dsmcad


## enable dsmcad – it is disabled by default after install

[root@linux-server ~]# systemctl enable dsmcad

[root@linux-server tsm]# systemctl status dsmcad

9. Check dmscad service is really running

Once enabled IBM TSM will spawn a process in the bacground dmscad if it started properly you should have the process backgrounded.

[root@linux-server tsm]# ps -ef|grep -i dsm|grep -v grep
root      2881     1  0 18:05 ?        00:00:01 /usr/bin/dsmcad

If process is not there there might be some library or something not at place preventing the process to start …

10. Check DSMCAD /var/tsm logs for errors

After having dsmcad process enabled and running in background

[root@linux-server tsm]# grep -i Version /var/tsm/sched.log|tail -1
12/03/2020 18:06:29   Server Version 8, Release 1, Level 10.000

 

[root@linux-server tsm]# cat /var/tsm/dsmerror.log

To see the current TSM configuration files we can  grep out comments *

[root@linux-server tsm]# grep -v '*' /opt/tivoli/tsm/client/ba/bin/dsm.sys

Example Configuration of the agent:
—————————————————-
   *TSM SERVER NODE Location
   Servername           tsm_server
   COMMmethod           TCPip
   TCPPort              1400
   TCPServeraddress     tsmserver2.backuphost.com
   NodeName             NODE.SERVER-TO-BACKUP-HOSTNAME.COM
   Passwordaccess       generate
   SCHEDLOGNAME         /var/tsm/sched.log
   SCHEDLOGRETENTION    21 D
   SCHEDMODE            POLLING

   ERRORLOGRETENTION    30 D
   INCLEXCL             /opt/tivoli/tsm/client/ba/bin/inclexcl.tsm

11. Remove tsm install directory tar ball and rpms to save space on system

The current version of Tivoli service manager is 586 Megabytes.

[root@linux-server tsm]# du -hsc 8.1.11.0-TIV-TSMBAC-LinuxX86.tar
586M    8.1.11.0-TIV-TSMBAC-LinuxX86.tar

Some systems are on purpose configured to have less space under their /home directory,
hence it is a good idea to clear up unnecessery files after completion.

Lets get rid of all the IBM Spectrum archive source files and the rest of RPMs used for installation.

[root@linux-server tsm]# rm -rf ~/tsm/{*.tar,*.rpm,*.gpg,*.htm,*.txt}

12. Check backups are really created on the configured remote Central backup server

To make sure after the upgrade the backups are continuously created and properly stored on the IBM Tivoly remote central backup server, either manually initiate a backup or wait for lets say a day and run dsmc client to show all created backups from previous day. To make sure you'll not get empty output you can on purpose modify some file by simply opening it and writting over without chaning anything e.g. modify your ~/.bashrc or ~/.bash_profile

## List all backups for '/' root directory from -fromdate='DD/MM/YY'

[root@linux-server tsm]# dsmc

How to fix Cyrillic text on Windows 7

I've reinstalled my HP provided company work notebook with Windows 7 Enterprise x86 and had troubles with seeing Cyrillic written text, letters and fonts.
The result after installing some programs and selecting as a default language Bulgarian during installation setup prompt let me to see in some programs and in some of my old written text file names and Cyrillic WIN CP1251 content to be showing a cryptic letters like in above screenshot.

If you're being curious what is causing the broken encoding cyrillic text, it is the fact that in past a lot of cyrillic default encoding was written in KOI-8R and WIN-CP1251 encoding which is not unicode e.g. not compatible with the newer standard encoding for cyrillic UTF-8. Of course the authors of some old programs and documents are not really responsbie for the messed up cyrillic as noone expected that every Cyrillic text will be in UTF-8 in newer times.

Thanksfully there is a way to fix the unreadable / broken encoding cyrillic text by:

Going too menus:

Start menu -> Control Panel -> Change display language -> Clock, Language and Religion

Once there click the Administratibe tab

and choose

Change system locale.

windows-7_administrative_tab_change-system-locale

Here if you're not logged in with administrator user you will be prompted for administrative privileges.

select-system-locale-choose-bulgarian-and-hit-ok-windows-7

Being there choose your language (country) to be:

Bulgarian (Bulgaria) – if you're like me a Bulgarian or Russian (if you're Russian / Belarusian / Ukrainian) or someone from the countries of ex-USSR.
Click OK

And reboot (restart) your computer in order to make the new settings active.
 

This should be it from now on all cyrillic letters in all programs / documents and file names on your PC should visualize fine just as it was intended more or less by the cyrillic assumed creator Saint Climent Ohridski who was a  who reformed Cyrillic from Glagolic alphabet.

how-to-change-reset-lost-TightVNC-administrator-password

I have installed TightVNC to a Windows host just a few weeks ago in order to be able to manage remotely a Windows host and forgot to write down the administrator password 🙂 (stoopid!)

I had to explain to a friend remotely how to change the TightVNC admin password and it was a complete nightmare!

Shortly here is the exact menus one who wants to reset the password of a TigthVNC server after forgotten:

Start -> All Programs -> TightVNC
-> TightVNC Server (Service Mode) ->
TightVNC Service - Offline Configuration.

In the configuration dialog to popup there are the Server and Administration tabs through which a new password can be set.

After the password is change either a restart of the TightVNC server is necessery or a restart of the Windows PC.

Start Event Viewer from Command Line (Prompt) – eventvwr.msc to Debug Windows server issues

Friday, November 6th, 2015

Reading Time: 2minuteseventvwrmsc-event-viewer-windows-7-screenshot-view-windows-log-and-dianose-errors

If you’re a sysadmin which needs to deal with Microsoft Windows servers locally or remotely via Remote Desktop RDP client (MSTSC.EXE) or inside a Windows Domain Controller, you will have to frequently debug Windows isseus or Application caused errors by reviewing debug information stored in Event Logs.

Event Viewer is a precious tool to debug often errors with missing libraries or failing programs on Windows boot and thus on M$ Windows it is the Swiss Army knife of sysadmin.
However as staring Event Viewer using the GUI menus, takes a lot of step and looses you time, e.g., you have to navigate to menus:

1. Start button Picture of the Start button
2. clicking Control Panel
3. clicking System and Security
4. clicking Administrative Tools
5.then double-clicking Event Viewer.‌
6. Granting Administrator permission required If you’re prompted for an administrator password or confirmation

It is much handier to just start it with a shortcut:

Press Windows (Button) + R
– To invoke run prompt

and type:

eventvwr.msc

In case if you’re running eventvwr.msc to connect to remote Windows Server run from command prompt (cmd.exe):

How to install nginx webserver from source on Debian Linux / Install Latest Nginx on Debian

Wednesday, March 23rd, 2011

Reading Time: 6minutes

Nginx install server logo
If you're running a large website consisting of a mixture of php scripts, images and html. You probably have noticed that using just one Apache server to serve all the content is not that efficient

Each Apache child (I assume you're using Apache mpm prefork consumes approximately (20MB), this means that each client connection would consume 20 mb of your server memory.
This as you can imagine is truly a suicide in terms of memory. Each request for a picture, css or simple html file would ask Apache to fork another process and will consume (20mb of extra memory form your server mem capacity)!.

Taking in consideration all this notes and the need for some efficiency here, the administrator should normally think about dividing the processing of the so called static content from the dynamic content served on the server.

Apache is really a nice webserver software but with all the loaded modules to serve dynamic content, for instance php, cgi, python etc., it's becoming not the best solution for handling a (css, javascript, html, flv, avi, mov etc. files).

Even a plain Apache server installation without (libphp, mod_rewrite mod deflate etc.) is still not dealing efficiently enough with the aforementioned static files content

Here comes the question if Apache is not that quick and efficient in serving static files, what then? The answer is caching webserver! By caching the regular static content files, your website visitors will benefit by experiencing shorter webserver responce files in downloading static contents and therefore will generally hasten your website and improve the end user's experience.

There are plenty of caching servers out there, some are a proprietary software and some are free software.

However the three most popular servers out there for static file content serving are:

  • Squid,
  • Varnish
  • Nginx

In this article as you should have already found out by the article title I'll discuss Nginx

You might ask why exactly Nginx and not some of the other twos, well simply cause Squid is too complicated to configure and on the other hand does provide lower performance than Nginx. On the other hand Varnish is also a good solution for static file webserver, but I believe it is not tested enough. However I should mention that my experience with testing varnish on my own home router is quite good by so far.

If you're further interested into varhisn cache I would suggest you checkout www.varhisn-cache.org .

Now as I have said a few words about squid and varhisn let's proceed to the essence of the article and say few words about nginx

Here is a quote describing nginx in a short and good manner directly extracted from nginx.com

nginx [engine x] is a HTTP and reverse proxy server, as well as a mail proxy server written by Igor Sysoev. It has been running for more than five years on many heavily loaded Russian sites including Rambler (RamblerMedia.com). According to Netcraft nginx served or proxied 4.70% busiest sites in April 2010. Here are some of success stories: FastMail.FM, WordPress.com.

By default nginx is available ready to be installed in Debian via apt-get, however sadly enough the version available for install is pretty much outdated as of time of writting the nginx debian version in lenny's deb package repositories is 0.6.32-3+lenny3

This version was release about 2 years ago and is currently completely outdated, therefore I found it is not a good idea to use this old and probably slower release of nginx and I jumped further to install my nginx from source:
Nginx source installation actually is very simple on Linux platforms.

1. As a first step in order to be able to succeed with the install from source make sure your system you have installed the packages:

debian:~# apt-get install libpcre3 libpcre3-dev libpcrecpp0 libssl-dev zlib1g-dev build-essential

2. Secondly download latest nginx source code tarball

Check out on http://nginx.com/download the latest stable release of nginx and further issue the commands below:

debian:~# cd /usr/local/src
debian:/usr/local/src# wget http://nginx.org/download/nginx-0.9.6.tar.gz

3.Unarchive nginx source code

debian:/usr/local/src#tar -zxvvf nginx-0.9.6.tar.gz
...

The nginx server requirements for me wasn't any special so I proceeded and used the nginx ./configure script which is found in nginx-0.9.6

4. Compline nginx server

debian:/usr/local/src# cd nginx-0.9.6
debian:/usr/local/src/nginx-0.9.6# ./configure && make && make install
+ Linux 2.6.26-2-amd64 x86_64
checking for C compiler ... found
+ using GNU C compiler
+ gcc version: 4.3.2 (Debian 4.3.2-1.1)
checking for gcc -pipe switch ... found
...
...

The last lines printed by the nginx configure script are actually the major interesting ones for administration purposes the default complation options in my case were:

Configuration summary
+ using system PCRE library
+ OpenSSL library is not used
+ md5: using system crypto library
+ sha1 library is not used
+ using system zlib library

nginx path prefix: "/usr/local/nginx"
nginx binary file: "/usr/local/nginx/sbin/nginx"
nginx configuration prefix: "/usr/local/nginx/conf"
nginx configuration file: "/usr/local/nginx/conf/nginx.conf"
nginx pid file: "/usr/local/nginx/logs/nginx.pid"
nginx error log file: "/usr/local/nginx/logs/error.log"
nginx http access log file: "/usr/local/nginx/logs/access.log"
nginx http client request body temporary files: "client_body_temp"
nginx http proxy temporary files: "proxy_temp"
nginx http fastcgi temporary files: "fastcgi_temp"
nginx http uwsgi temporary files: "uwsgi_temp"
nginx http scgi temporary files: "scgi_temp"

If you want to setup nginx server to support ssl (https) and for instance install nginx to a different server path you can use some ./configure configuration options, for instance:

./configure –sbin-path=/usr/local/sbin –with-http_ssl_module

Now before you can start the nginx server, you should also set up the nginx init script;

5. Download and set a ready to use script with cmd:

debian:~# cd /etc/init.d
debian:/etc/init.d# wget https://pc-freak.net/files/nginx-init-script
debian:/etc/init.d# mv nginx-init-script nginx
debian:/etc/init.d# chmod +x nginx

6. Configure Nginx

Nginx is a really easy and simple server, just like the Russians, Simple but good!
By the way it's interesting to mention nginx has been coded by a Russian, so it's robust and hard as a rock as all the other Russian creations 🙂
Nginx configuration files in a default install as the one in my case are to be found in /usr/local/nginx/conf

In the nginx/conf directory you're about to find the following list of files which concern nginx server configurations:

deiban:/usr/local/nginx:~# ls -1
fastcgi.conf
fastcgi.conf.default
fastcgi_params
fastcgi_params.default
koi-utf
koi-win
mime.types
mime.types.default
nginx.conf
nginx.conf.default
scgi_params
scgi_params.default
uwsgi_params
uwsgi_params.default
win-utf

The .default files are just a copy of the ones without the .default extension and contain the default respective file directives.

In my case I'm not using fastcgi to serve perl or php scripts via nginx so I don't need to configure the fastcgi.conf and fastcgi_params files, the scgi_params and uwsgi_params conf files are actually files which contain nginx configuration directives concerning the use of nginx to process SSI (Server Side Include) scripts and therefore I skip configuring the SSI conf files.
koi-utf and koi-win are two files which usually you don't need to configure and aims the nginx server to support the UTF-8 character encoding and the mime.types conf is a file which has a number of mime types the nginx server will know how to handle.

Therefore after all being said the only file which needs to configured is nginx.conf

7. Edit /usr/local/nginx/conf/nginx.conf

debian:/usr/local/nginx:# vim /usr/local/nginx/conf/nginx.conf

Therein you will find the following default configuration:

#gzip on;

server {
listen 80;
server_name localhost;

#charset koi8-r;

#access_log logs/host.access.log main;

location / {
root html;
index index.html index.htm;
}
#error_page 404 /404.html;

# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}

In the default configuration above you need to modify only the above block of code as follows:

server {
listen 80;
server_name yoursitedomain.com;

#charset koi8-r;

#access_log logs/access.log main;

location / {
root /var/www/yoursitedomain.com/html;
index index.html index.htm;
}

Change the yoursitedomain.com and /var/www/yoursitedomain.com/html with your directory and website destinations.

8. Start nginx server with nginx init script

debian:/usr/local/nginx:# /etc/init.d/nginx start
Starting nginx:

This should bring up the nginx server, if something is miss configured you will notice also some error messages, as you can see in my case in above init script output, thanksfully there are no error messages.
Note that you can also start nginx directly via invoking /usr/local/nginx/sbin/nginx binary

To check if the nginx server has properly started from the command line type:

debian:/usr/local/nginx:~# ps ax|grep -i nginx|grep -v grep
9424 ? Ss 0:00 nginx: master process /usr/local/nginx/sbin/nginx
9425 ? S 0:00 nginx: worker process

Another way to check if the web browser is ready to serve your website file conten,t you can directly access your website by pointing your browser to with http://yoursitedomain.com/, you should get your either your custom index.html file or the default nginx greeting Welcome to nginx

9. Add nginx server to start up during system boot up

debian:/usr/local/nginx:# /usr/sbin/update-rc.d -f nginx defaults

That's all now you have up and running nginx and your static file serving will require you much less system resources, than with Apache.
Hope this article was helpful to somebody, feedback on it is very welcome!

Play Dune2 on Debian Linux with dosbox – Dune 2 Mother of all Real Time Strategy games

Dune II: The Building of a Dynasty (known also as Dune II: Battle for Arrakis in Europe is a game that my generation will never forget. Dune 2 is the "first" computer Real Time Strategy (RTE) game of the genre of the Warcraft I and Warcraft II / III and later Command and Conquer – Red Aleart, Age of Empires I / II and Starcraft …

dune2-unit-destroyed

I've grown up with Dune2 and the little computer geek community in my school was absolutely crazy about playing it. Though not historically being the first Real Time Strategy game, this Lucas Inc. 
game give standards that for the whole RTE genre for years and will stay in history of Computer Games as one of best games of all times.

I've spend big part of my teenager years with my best friends playing Dune2 and the possibility nowadays to resurrect the memories of these young careless years is a blessing.  Younger computer enthusiasts and gamers probably never heard of Dune 2 and this is why I decided to place a little post here about this legendary game.

dune-2-tank-vehicle - one of best games computer games ever

Its worthy out of curiosity or for fun to play Dune 2 on modern OS be it Windows or Linux. Since Dune is DOS game, it is necessary to play it via DOS emulator i.e. – (DosBox). 
Here is how I run dune2 on my Debian Linux:

1. Install dosbox DOS emulator

apt-get install --yes dosbox

2. Download Dune2 game executable

You can download my mirror of dune2 here

Note that you will need unzip to uanrchive it, if you don't have it installed do so:

apt-get install --yes unzip

cd ~/Downloads/
wget https://pc-freak.net/files/dune-2.zip

3.  Unzip archive and create directory to mount it emulating 'C:\' drive

mkdir -p ~/.dos/Dune2
cd ~/.dos/Dune2

unzip ~/Downloads/dune-2.zip
 

4. Start dosbox and create permanent config for C: drive auto mount


dosbox

To make C:\ virtual drive automatically mounted you have to write a dosbox config from inside dbox console

config -writeconf /home/hipo/.dosbox.conf

My home dir is in /home/hipo, change this with your username /home/username

Then exit dosbox console with 'exit' command

To make dune2 game automatically mapped on Virtual C: drive:

echo "mount c /home/hipo/.dos" >> ~/.dosbox.conf

Further to make dosbox start each time with ~/.dosbox.conf add alias to your ~/.bashrc 

vim ~/.bashrc
echo "alias dosbox='dosbox -conf /home/hipo/.dosbox.conf'" >> ~/.bashrc
source ~/.bashrc

Then to run DUNE2 launch dosbox:

dosbox

and inside console type:

c:
cd Dune2
Dune2.exe

For the lazy ones who would like to test dune you can play dune 2 online on this website

Make QMAIL with vpopmail vchkpw, courier-authlib and courier-imap auth work without MySQL on Debian Linux qmailrocks Thibs install

Friday, September 28th, 2012

Reading Time: 5minutesHow to make qmail vpopmail vchkpw courier-authlib and courier-imap work storing mails on hard disk with qmailrocks Thibs install

Recently installed a new QMAIL, following mostly Thibs Qmailrocks install guide. I didn’t followed literally Thibs good guide, cause in his guide in few of the sections like Install Vpopmail he recommends using MySQL as a Backend to store Vpopmail email data and passwords; I prefer storing all vpopmail data on the file system as I believe it is much better especially for tiny QMAIL mail servers with less than 500 mail box accounts.

In this little article I will explain, how I made Vpopmail courier-authlib and courier-imap play nice together without storing data in SQL backend.

1. Compile vpopmail with file system data storage support

So here is how I managed to make vpopmail + courier-authlib + courier-imap, work well together:

First its necessery to compile Vpopmailin store all its users data and mail data on file system. For this in Thibs Vpopmail Intsall step compiled Vpopmail without support for MySQL, e.g. instead of using his pointed compile time ./configure, arguments I used:


# cd /downloads/vpopmail-5.4.33
# ./configure \
--enable-qmaildir=/var/qmail/ \
--enable-qmail-newu=/var/qmail/bin/qmail-newu \
--enable-qmail-inject=/var/qmail/bin/qmail-inject \
--enable-qmail-newmrh=/var/qmail/bin/qmail-newmrh \
--enable-tcprules-prog=/usr/bin/tcprules \
--enable-tcpserver-file=/etc/tcp.smtp \
--enable-clear-passwd \
--enable-many-domains \
--enable-qmail-ext \
--enable-logging=y \
--enable-auth-logging \
--enable-libdir=/usr/lib/ \
--disable-roaming-users \
--disable-passwd \
--enable-domainquotas \
--enable-roaming-users
....
....
# make && make install-strip
# cat > ~vpopmail/etc/vusagec.conf < < __EOF__
Server:
Disable = True;
__EOF__
echo 'export PATH=$PATH:/var/qmail/bin/:/home/vpopmail/bin/' > /etc/profile.d/extrapath.sh
chmod +x /etc/profile.d/extrapath.sh
source /etc/profile

A tiny shell script with all above options to compile (qmail) vpopmail without MySQL / PostgreSQL support is here

For other steps concerning creation of vpopmail/vchkpw – user/group just follow as Thibs suggests.

2. Compile and install courier-authlib-0.59.1

I’ve made mirror of courier-authlib.0.59.1.tar.gz cause this version includes support for vchkpw without mysql, its a pity newer versions of courier-authlib not any more have support for vpopmail to store its data directly on the hard disk.

Then on downlaod, compile && install courier-authlib:

Download authlib courier-authlib.0.59.1.tar.gz – (I made mirror of courier-authlib.0.59.1.tar.gz you can use my mirror or download it somewhere else from the net):


# cd /usr/local/src
# wget -q https://pc-freak.net/files/courier-authlib.0.59.1.tar.gz
# tar -zxvvf courier-authlib.0.59.1.tar.gz

Compile courier-authlib

# ./configure --prefix=/usr/local --exec-prefix=/usr/local --with-authvchkpw --without-authldap --without-authmysql --disable-root-check --with-ssl --with-authchangepwdir=/usr/local/libexec/authlib
....
# make && make install && make install-strip && make install-configure
....

On Debian Squeeze, this version of courier-authlib compiles fine, on Debian Lenny I use it too and there it is okay.

Unless above commands returns a compile error authlib will be installed inside /usr/local/libexec. If you get any errors it is most likely due to some missing header files. The error should be self explanatory enough, but just in case you have troubles to find what deb is necessery to install, please check here the complete list of installed packages I have on the host . In case of problems the quickest way (if on Debian Squeeze) is to install same packages, type:


# wget -q https://pc-freak.net/files/list_of_all_deb_necessery_installed_packages_for_authlib.txt
# for i in $(cat list_of_all_deb_necessery_installed_packages_for_authlib.txt |awk '{ print $2 }'); do
apt-get install --yes $i;
done

This is for the lazy ones though it might install you some packs you don’t like to have on your host, so just install it in case you know what you’re doing 🙂

Next step is to set proper configuration for courier-authdaemon.

3. Configure courier-authlib in /usr/local/etc/authlib

Again for the lazy ones I have prepared a good config which is working 100% with vpopmail configured to store mails on the file system, to install the “good” configs, fetch mine and put them in proper location, e.g.:


# cd /usr/local/etc
# wget -q https://pc-freak.net/files/authlib-config-for-qmail-with-hdd-directory-stored-userdata.tar.gz
# tar -zxvvf authlib-config-for-qmail-with-hdd-directory-stored-userdata.tar.gz
....

For those who prefer not to use my configuration as pointed above, here is what you will need to change manually in configs:

Edit /usr/local/etc/authlib/authdaemonrc and make sure there variable authmodulelist and authmodulelist and daemons=5
equals to:


authmodulelist="authvchkpw"


authmodulelistorig="authuserdb authpgsql authldap authmysql authcustom authvchkpw authpipe"


daemons=10

Bear in mind here the setting daemons, will set how many maximum parallel connections should be possible to authdaemond on new IMAP fetch mail user requests. Setting it to 10 will allow your mail server to support up to 10 users to paralelly check your mail for a tiny mail server this setting is okay if you expect higher number of parallel mail users raise the setting to some setting fitting your needs.

P.S. On some qmail installations this value has created weird problems and took me hours to debug the whole mess is caused by this setting, make sure you plan it now unless you don’t to loose some time in future.

4. Stop debian courier-authdaemon and start custom compiled one

Now all is ready and authdaemond can be started, but before that if you have installed courier-authlib as a debian package you need to stop it via init script and only when completely sure old default Debian courier-authdaemon is stopped launch the new installed one:


# /etc/init.d/courier-authdaemon stop
# s ax |grep -i authdaemond |grep -v grep
#
# /usr/local/sbin/authdaemond start
#

To make the newly custom source installed courier-authdaemon to load itself on system boot instead of the debian installed package


# dpkg -l |grep -i courier-authdaemon
ii courier-authdaemon 0.63.0-3 Courier authentication daemon

open /etc/init.d/courier-authdaemond, after line:


. /lib/lsb/init-functions

add


/usr/local/sbin/authdaemond start
exit 0

This will make the script exit once launches cmd /usr/local/sbin/authdaemond start

5. Compile and Install courier-imap

You will also have to install from courier-imap archive source, I have tested it and know Qmail + Vpopmail + Courier-Imap works for sure with version courier-imap-4.1.2.tar.bz2

As of time of writing this post courier-imap-4.11.0.tar.bz2 is the latest available for download from Courier-imap download site unfortunately this version requires higher version of >= courier-authlib-0.63

In order install courier-imap-4.1.2.tar.bz2


# cd /usr/local/src
# wget -q https://pc-freak.net/files/courier-imap-4.1.2.tar.bz2
# tar -jxvvf courier-imap-4.1.2.tar.bz2
...
# chown -R hipo:hipo courier-imap-4.1.2
# su hipo
$ cd courier-imap-4.1.2/
$ export CFLAGS="-DHAVE_OPEN_SMTP_RELAY -DHAVE_VLOGAUTH"
$ export COURIERAUTHCONFIG=/usr/local/bin/courierauthconfig
$ export CPPFLAGS=-I/usr/local/courier-authlib/include
$ ./configure --prefix=/usr/local/courier-imap --disable-root-check
...
$ exit
# make
...
# make install
...
# make install configure

It is recommended courier-imap to be compiled with non root username. In above code I use my username hipo, other people have to use any non-root user.

6. Set proper configuration and new init script for courier-imap

In /usr/lib/courier-imap, download following working configs (for convenience I’ve made tar with my configs):


# cd /usr/lib/courier-imap
# rm -rf etc
# wget -q https://pc-freak.net/files/courier-imap-config-etc.tar.gz

Then you will have to overwrite default courier-imap init script in /etc/init.d/courier-imap with another one to start the custom compiled one instead of debian default installed courier-imap


# mv /etc/init.d/courier-imap /root
# cd /etc/init.d
# wget -q https://pc-freak.net/files/debian-courier-imap
# mv debian-courier-imap courier-imap
# chmod +x courier-imap

This init script is written use /var/lock/subsys/courier-imap, so you will have to also create /var/lock/subsys/


# mkdir -p /var/lock/subsys

7. Start custom installed courier-imap

The start/stop init script of newly installed courier-imap is /usr/lib/courier-imap/libexec/imapd.rc


/usr/lib/courier-imap/libexec/imapd.rc start

Since a new /etc/init.dcourier-imap is installed too, it can be also used to control courier-imap start/stop.

Well thats should be enough for Courier-authlib and Courier-Authlib to communicate fine between each other and be able to connect and fetch e-mail stored in file system by vpopmail.

8. Test if Qmail IMAP proto finally works


# telnet localhost 143

That’s all it works. Enjoy 🙂

Install TorrentFlux Bit Torrent Web management interface on Debian / Ubuntu Linux

Tuesday, July 15th, 2014

Reading Time: 5minutes

torrent flux logo
Torrentflux
is web based, feature-rich BitTorrent download manager.
Torrentflux is a must have installed server software for anyone who does regular torrent downloads and want to access the downloads from anywhere on the internet.

TorrentFlux is a PHP based BitTorrent controller that runs on a web
 server. It can manage all of your BitTorrent downloads from anywhere
 through a convenient and easy-to-use web interface.
 .
 TorrentFlux uses a MySQL database to manage the downloads.

 TorrentFlux enables you to run BitTorrent downloads unattended on a monitor-less or remote server 24 hours a day, while still maintaining complete control from any web browser. Now you can control your  downloading on your firewall, or keep up with downloads while on  vacation. It uses the BitTornado client to download files, and also  requires a web server with PHP.
 
 Some of the Torrentflux features:

   * Upload Torrents via URL or File Upload
   * Start, Stop, and Delete Torrents with ease
   * Advanced Torrent start options (ports, speeds, etc.)
   * Multi-user interface
   * RSS Feeds, download Torrents files with a click
   * Run several torrents at once
   * View Download Progress of all torrents at a glance
   * View drive space at a glance
   * View Torrent file meta information
   * Built-in User management and Security
   * Private Messaging
   * Themes (selectable per user)
   * Upload History

 

Before installing Bittorrent you will need to have a running version of Debian, Ubuntu or any other debian derivative (though it can easily be run on any Linux distro). To install AMP (Apache MySQL Server, PHP) you can follow first part of my previous article Installing Usual PHP Apache MySQL for new Debian GNU / Linux installs.

So what for is TorrentFlux Useful?
Torrenflux is precious and must have if you have to access filtered torrent from outside of your homecountry and you have a running server already in your home country in that I was using TorrentFlux to access Bulgarian Zamunda.Net Torrent Tracker from Holland and was downloading first movies from the Bulgarian Torrent Tracker to my Fluxbox installed on my Dobrich home router and then used FTP to transfer movies to the Netherlands. Talking about many people choose to also install VSFTP and use it together with Torrentflux …

1. Install TorrentFlux and its dependencies (BitTornado, Bittorrent, Zip, Unzip, Bzip etc.) the "Debian Way"


On my Debian 7 Wheezy home machine  I run

apt-get install –yes bzip2 php5-gd php5-cli unrar-free grep python net-tools mawk wget unzip cksfv vlc-nox uudeview python-crypto libxml-simple-perl libxml-dom-perl libdbd-mysql-perl bittorrent bittornado


a) Install TorrentFlux the Debian Way

apt-get install –yes torrentflux


You will be prompted with a coule of screens, to set a new MySQL database user and password and SQL database, as well as offered to restart Apache to make Torrentflux accessible like as on below screenshots.

configuring-torrentflux-debian-linux-screenshot-2


configuring-torrentflux-debian-linux-screenshot 3

configuring-torrentflux-debian-linux-screenshot-4

To make new installed torrentflux accessible from web you will either have to configure it via some new Apache VirtualHost or make a symbolic link to /usr/share/torrentflux/www :
 

cd /var/www/
ln -sf /usr/share/torrentflux/www/ torrentflux


That's all you're all done to access torrentflux either access it via your default configured webserver domain name or via localhost if you're logged in to same pc where installing.

http://www.your-domain.com/torrentflux

or

http://127.0.0.1/torrentflux

configuring-torrentflux-after-first-login-in-web-debian-linux

2. Install latest Torrentflux version from source

Alternatively if you want to have the latest version (because the Debian version is part of the stable distribution is a little bit outdated you will have to fetch Torrentflux-b4rt and unarchive it:

cd /tmp/
wget http://download.berlios.de/tf-b4rt/torrentflux-b4rt_1.0-beta2.tar.bz2

tar -xjf torrentflux-b4rt_1.0-beta2.tar.bz2

mv torrentflux-b4rt_1.0-beta2 /opt/torrentflux

Then to make torrentflux visible from web server I had to create a symbolic link to installation directory:
 

ln -sf /opt/torrentflux/html /var/www/torrentflux

For further initial configuration its necessery to make Torrentflux config writtable by www-data (the user with which Apache is running on Debian).

 

chown -R www-data:www-data /var/www/torrentflux/inc/config/


Next it its required to create somewhere download folder where TorrentFlux will keep downloaded Torrents

mkdir /var/lib/torrentflux


Apache HTTP server will have to have write ther:

chown -R www-data:www-data /var/lib/torrentflux


If you already haven't restarted Apache earlier in installing TorrentFlux pre-requirements, you will have to do it now:

 

/etc/init.d/apache2 restart


As TorrentFlux depends on its MySQL backend, we need to also create manually TorrentFlux database username and a password
 

export SQL_DB='torrentflux';
TFLUXSQL_USERNAME='torrentflux';
TFLUX_SQL_PWD='any-secret-password';

echo "CREATE DATABASE IF NOT EXISTS $SQL_DB DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_unicode_ci"
| mysql –user=root –password

echo "GRANT ALL PRIVILEGES ON $SQL_DB.*
TO $TFLUXSQL_USERNAME@localhost
IDENTIFIED BY $TFLUX_SQL_PWD;" | mysql –user=root –password

 

Substitute with your Database, Username and Password above shell variables – $SQL_DB, $TFLUX_USERNAME, $TFLUX_SQL_PWD

To configure TorrentFlux access it in browser:

http://your-domain.com/torrentflux
 

By accessing it for a first time, you will redirected to setup.php, in case something goes wrong and yuo're not redirected (probably some mod_rewrite issues add setup.php to url – e.g., acess –

http://your-domain.com/torrentflux/setup.php

I will not enter details, about Web config, because everything there is pretty clear.

Just in short – you will have to now choose:

Choose Database
Choose Database Information of database (put in the exact name of TorrentFlux databse previously created)
Uncheck the box for "Create new database"
Choose as a download location upper created directory – /var/lib/torrentflux

If you get an error on software dependencies screen for missing unrar – just install it
VLC may show an error as well, that's not a problem because VLC is probably not to be used.
Finally after completion of all, you will get an error that setup.php cannot be deleted.
 

To prevent, someone to re-configure it through http://your-domain/torrentflux/setup.php URL remove setup.php


rm /var/www/torrentflux/setup.php

To prevent someone rewrite anything in config file from web we have to revert back config/ folder not to be writable by Apache


chown -R root:root /var/www/torrentflux/inc/config/

Now in browser to access torrentflux type:


http://ipofyourbox/torrentflux

/torrentflux should redirect you to login.php if for some reason it doesn't type it manually in URL.

First account you will login is the super user account, you can allow multiple users to use it by adding multiple accounts.

torrentflux-install-on-debian-ubuntu-gnu-linux-web-management-torrent-interface

As you will see there is plety of configuration options to play with.

You will definitely want to look in Server Page, some very important page to look is the Transfer Page – from there you can adjust the bandwidth of your connection on 100Mbit network this would be 12500 – to use the maximum possible connection provided by your ISP set the max bandwidth to 0. You have the option to also set a default bittorrent client, by default this will be bittornado.


If you have troubles downloading from TorrentTrackers make sure your router is configured to forward port 49160 to 49300

Now if you have a lot of storage create accounts also for your friends and enjoy torrentflux 🙂
 

 

Windows key Shortcuts and Commands List every Win admin / support must know

Tuesday, November 25th, 2014

Reading Time: 8minutes

windows-XP-vista-7-8-server-2003-rc2-2012--full-complete-keyboard-shortcuts-list
If you're a system administrator of Windows Servers or or just a PC support in a small company and you have to fix PCs running Microsoft Windows XP / 7 / 8  daily, sooner or later you will be interested into how to optimize your windows maintainance work to be able to do more adminsitration work for less time.

M$ Windows OShas evolved a lot over the past 10+ years and many of the features available GUI are now either possibile to be done via a standard commands and the GUI interfaces. Various adminsitration and common daily work simplification goodies are now accessible through quick access shortcutsand commands.

Virtually all Windows operating system environment could be now customized by using such shortcuts, this reduces the multitude of annoying double clicks which are truely pissing off sysadmins and tech-supports involved in  Windows Ticket solving.

Win Shortcuts and Commands helps to:

  • Quickly invoke almost all System Settings available from Windows Control Panel
  • Access all admins tools GUIs throguh command
  • Speed upOpening Video, Pictures, Documents, Downloads folders start Windows Update, Configure Printers / Fax / Add Sharings

etc..

A lot of the commands were new to me thus I decided to try out all of the commands in command prompt (cmd). Many of the tools down-mentioned were news to me and let me understand better on Windows Internals, so if you time try them out.

How to manually disable Windows Genuine Advantage on Windows XP SP2

Wednesday, May 25th, 2011

Reading Time: < 1minute
WGA Notification message popup message

I have a pirate version of Windows XP Pro 2 installer CD which does automatically turn on Windows Genuine Advantage

This is kind of annoying as the computer gets really slow and the hard disk drive activite gets intensive as well as an annoying popup message that the Windows XP copy is not genuine does appear periodically

In order to get rid of the message I had to do the following steps:

1. Get into Windows Safe Mode without Networking

As most of the people knows this is achieved by pressing F8 keyboard key right before the Windows bootup screen appears.

After in Safe mode it’s necessery to,

2. Run Windows Command Line (cmd.exe)

To do so follow, the menus:

Windows (Start Menu) -> Run -> cmd.exe

3. In the command prompt window issue the commands:

C:Documents and SettingsUser> cd WindowsSystem32
C:WindowsSystem32> taskkill -IM wgatray.exe
C:WindowsSystem32> del wgatray.exe
C:WindowsSystem32> move wgalogon.dll wgalogon.dll.old
C:WindowsSystem32> del wgalogon.dll.old

Something to mention is you have to be really quick, with deleting wgalogon.dll, cause wgatray.exe is scheduled to run every 1 / 2 seconds 🙂 It is a bit of situation of type “be quick or be dead” as Maiden used to sing 🙂
A Windows system restart and Hooray the Windows Genuine message is gone 🙂
