I had to setup a QMAIL auto reply (Out of the Office) message on 5 email addresses and since I haven't done it for a long time it took me a couple 20 minutes to consult Qmail (Life With Qmail http://lifewithqmail.org (great website!) documentation and read a couple of online forum threads until I finally remembered, how I used to be setting up a vacation message manually via qmail's .qmail file.
Of course Setting qmail auto reply can always be done via QmailAdmin or VQadmin .. – Qmail Vpopmail web frontends however on many Qmail mail servers Qmailadmin or/and VQadmin is absent due to some reason or even on a big mail servers the server doesn't run Apache at all. Hence it is good to know how to set qmail vacation message directly via plain SSH terminal connection and this is why how this article got born.
So here is how I enable qmail auto reply "manually", through .qmail for my email address info@my-email-domain.com:
1. Set a /var/vpopmail/domains/my-email-domain.com/info/.qmail file with the following content:
| /usr/bin/autorespond 86400 3 /home/vpopmail/domains/my-email-domain.com/info/vacation/message /home/vpopmail/domains/my-email-domain.com/info/vacation
2. Create /home/vpopmail/domains/my-email-domain.com/info/vacation directory
linux:~# mkdir -p /home/vpopmail/domains/my-email-domain.com/info/vacation/
3. Create /home/vpopmail/domains/my-email-domain.com/info/vacation/message file with auto reply message
First create the message file with touch command:
linux:~# touch /home/vpopmail/domains/my-email-domain.com/info/vacation/message
Then put with vim or mcedit etc. an auto-reply vacation message similar to the sample below:
From: info@cadiainsurance.com
Subject: We have received your message. Thank you!
Dear Customer, we thank you for the interest in our services.
A member of our team will reply promptly to your enquiry shortly.
4. Set proper permissions for vacation/message and .qmail files
/home/vpopmail/domains/my-email-domain.com/info/vacation/message and /home/vpopmail/domains/my-email-domain.com/info/.qmail files has to be owned by user/group vpopmail:vchkpw, e.g.:
linux:~# chown -R vpopmail:vchkpw /home/vpopmail/domains/my-email-domain.com/info/vacation
linux:~# chown vpopmail:vchkpw /home/vpopmail/domains/my-email-domain.com/info/.qmail
If you are a qmail administration with the requirement to create auto reply message for employees going on a holiday often (in a middle sized company office), setting up the out of the office auto reply manually one by one is a time consuming, annoying task and "crazy" task. Therefore some time ago while still I was employed in a Bulgarian mid-sized company called Design.BG, I've written a tiny shell script which creates qmail email users vacation messages by passing few arguments.
Here is my create_vpopmail_vacation.sh shell script
Note that this script might have a lot of bugs and is not much tested, so read it carefully and test it before you put it for daily use 
Happy Hacking!

One of my friends Windows 7 started returning errors while trying to open from My Computer the local Windows C, D and E drives.
This error appeared immediately, after malware and registry fix up programs were run on the PC. The exact programs that lead his PC into the state of returning an error:
This file does not have a program associated with it for performing this action. Create an association in the Set Associations control panel
are:
- a-squared
- Registry Booster
This two programs by the way are doing quite a good job on fixing Windows XP and Windows Vista PCs which were cleaned up earlier with Malware Bytes and Avira , however it seems they're not 100% still compatible with the Windows 7 registry database or some uncleaned malware or virus on the PC has post-messed up the registry file associations. As its always the case with Windows you don't have a clear idea what's going …
Anyways as said the PC was in a bad situation, where neither Windows Explorer nor in any mean the disk drives can be opened or red, hence there was need for a quick way to revert back the default Windows file association registry settings After some quick research online, I've found an archive containing default Windows registry values for file associations
Therefore to revert back all Windows 7 file extensions from Windows install time, I had to download the file All_Default_File_Extensions.zip , extract the archive with WinZip or WinRar and run each of archive contained .reg extension files. The .reg files had to be run with Administrator account. It takes a while and its a bit irritating until all of the .reg files are run and all the file association default Windows settings are reverted back but thankfully in the end the C drive opening error:
This file does not have a program associated with it for performing this action … is resolved. Cheers

If you're looking for a command line utility to generate PDF file out of any webpage located online you are looking for Wkhtmltopdf
The conversion of webpages to PDF by the tool is done using Apple's Webkit open source render.
wkhtmltopdf is something very useful for web developers, as some webpages has a requirement to produce dynamically pdfs from a remote website locations.
wkhtmltopdf is shipped with Debian Squeeze 6 and latest Ubuntu Linux versions and still not entered in Fedora and CentOS repositories.
To use wkhtmltopdf on Debian / Ubuntu distros install it via apt;
linux:~# apt-get install wkhtmltodpf
...
Next to convert a webpage of choice use cmd:
linux:~$ wkhtmltopdf www.pc-freak.net pc-freak.net_website.pdf
Loading page (1/2)
Printing pages (2/2)
Done
If the web page to be snapshotted in long few pages a few pages PDF will be generated by wkhtmltopdf
wkhtmltopdf also supports to create the website snapshot with a specified orientation Landscape / Portrait
-O Portrait options to it, like so:
linux:~$ wkhtmltopdf -O Portrait www.pc-freak.net pc-freak.net_website.pdf
wkhtmltopdf has many useful options, here are some of them:
- Javascript disabling – Disable support for javascript for a website
- Grayscale pdf generation – Generates PDf in Grayscale
- Low quality pdf generation – Useful to shrink the output size of generated pdf size
- Set PDF page size – (A4, Letter etc.)
- Add zoom to the generated pdf content
- Support for password HTTP authentication
- Support to use the tool over a proxy
- Generation of Table of Content based on titles (only in static version)
- Adding of Header and Footers (only in static version)
To generate an A4 page with wkhtmltopdf:
wkhtmltopdf -s A4 www.pc-freak.net/blog/ pc-freak.net_blog.pdf
wkhtmltopdf looks promising but seems a bit buggy still, here is what happened when I tried to create a pdf without setting an A4 page formatting:
linux:$ wkhtmltopdf www.pc-freak.net/blog/ pc-freak.net_blog.pdf
Loading page (1/2)
OpenOffice path before fixup is '/usr/lib/openoffice' ] 71%
OpenOffice path is '/usr/lib/openoffice'
OpenOffice path before fixup is '/usr/lib/openoffice'
OpenOffice path is '/usr/lib/openoffice'

Debian and Ubuntu version of wkhtmltopdf does not support TOC generation and Adding headers and footers, to support it one has to download and install the static version of wkhtmltopdf
Using the static version of the tool is also the only option for anyone on Fedora or any other RPM based Linux distro.

Its common thing that CMS systems and many developers custom .htaccess cause issues where websites depending on mod_rewrite fails to work properly. Most common issues are broken redirects or mod_rewrite rules, which behave differently among the different mod_rewrite versions which comes with different versions of Apache.
Everytime there are such problems its necessery that mod_rewrite's RewriteLog functionality is used.
Even though the RewriteLog mod_rewrite config variable is well described on httpd.apache.org , I decided to drop a little post here as I'm pretty sure many novice admins might not know about RewriteLog config var and might benefit of this small article.
Enabling mod_rewrite requests logging of requests to the webserver and process via mod_rewrite rules is being done either via the specific website .htaccess (located in the site's root directory) or via httpd.conf, apache2.conf etc. depending on the Linux / BSD linux distribution Apache config file naming is used.
To enable RewriteLog near the end of the Apache configuration file its necessery to place the variables in apache conf:
1. Edit RewriteLog and place following variables:
RewriteLogLevel 9
RewriteLog /var/log/rewrite.log
RewriteLogLevel does define the level of logging that should get logged in /var/log/rewrite.log
The higher the RewriteLogLevel number defined the more debugging related to mod_rewrite requests processing gets logged.
RewriteLogLevel 9 is actually the highest loglevel that can be. Setting the RewriteLogLevel to 0 will instruct mod_rewrite to stop logging. In many cases a RewriteLogLevel of 3 is also enough to debug most of the redirect issues, however I prefer to see more, so almost always I use RewriteLogLevel of 9.
2. Create /var/log/rewrite.log and set writtable permissions
a. Create /var/log/rewrite.log
freebsd# touch /var/log/rewrite.log
b. Set writtable permissons
Either chown the file to the user with which the Apache server is running, or chmod it to permissions of 777.
On FreeBSD, chown permissions to allow webserver to write in file, should be:
freebsd# chown www:www /var/log/rewrite.log
On Debian and alike distros:
debian:~# chown www-data:www-data /var/log/rewrite.log
On CentOS, Fedora etc.:
[root@centos ~]# chown httpd:httpd /var/log/rewrite.log
On any other distribution, you don't want to bother to check the uid:gid, the permissions can be set with chmod 777, e.g.:
linux# chmod 777 /var/log/rewrite.log
Next after RewriteLog is in conf to make configs active the usual webserver restart is required.
To restart Apache On FreeBSD:
freebsd# /usr/local/etc/rc.d/apache2 restart
...
To restart Apache on Debian and derivatives:
debian:~# /etc/init.d/apache2 restart
...
On Fedora and derivive distros:
[root@fedora ~]# /etc/init.d/httpd restart
...
Its common error to forget to set proper permissions to /var/log/rewrite.log this has puzzled me many times, when enabling RewriteLog's logging.
Another important note is when debugging for mod_rewrite is enabled, one forgets to disable logging and after a while if the /var/log partition is placed on a small partition or is on an old server with less space often the RewriteLog fills in the disk quickly and might create website downtimes. Hence always make sure RewriteLog is disabled after work rewrite debugging is no longer needed.
The way I use to disable it is by commenting it in conf like so:
#RewriteLogLevel 9
#RewriteLog /var/log/rewrite.log
Finally to check, what the mod_rewrite processor is doing on the fly its handy to use the well known tail -f
linux# tail -f /var/log/rewrite.log
A bunch of time in watching the requests, should be enough to point to the exact problem causing broken redirects or general website malfunction.
Cheers

On a couple of occasions, I've had the issue of loosing / forgetting a MySQL password at other times I had to login to servers which contained MySQL servers with a password I don't know.
In any of this occasions I was required to restore the ROOT access to the mysql server.
Sadly recoving a mysql lost root password is not really possible in a easy way, thus in most cases the only option one have is to stop the mysql server and run it again in a special skip-grant-tables mode, which runs the server in a sort of passwordless safe mode and makes it accessible without admin password through mysql cli .
To Omit the password check the skip-grant-table option instructs the MySQL server not to check in mysql.user while any request to connect with mysql client to the server is made.
Therefore one can login to the mysql server passwordless and reset the current (lost) password to another one.
Thease can be achived in the following four easy steps:
1. Stop the MySQL server
mysql:~# /etc/init.d/mysqld stop
2. Run the mysql server with the –skip-grant-tables option
mysql:~# mysqld_safe --skip-grant-tables &
3. Login to the mysql and change current mysql root password
mysql:~# mysq -u root
mysql> UPDATE user SET password=PASSWORD('yournewpassword') \
WHERE user='root';
mysql> FLUSH privileges;
4. Stop and Start the Mysql server again
mysql:~# killall -9 mysqld_safe
mysql:~# /etc/init.d/mysqld start
..
Now the new mysql password will be identical to the yournewpassword . Cheers

In my quest to know Linux better and use it capabilities to fulfill a multimedia tasks I came across the question:
How can I extract audio sound and music from Flash Videos .flv file format?
After a bit of investigation online I’ve found out in order to achieve this task the quickest way is via the handy ffmpeg conversion tool .
It’s rather easy actually, all necessery to do the conversion is to have the ffmpeg installed.
FFMpeg is part of Debian and Ubuntu repositories, so if you haven’t installed it yet, go straigh and install it with:
debian:~# apt-get install ffmpeg
...
Many modern day Linux distributions already have the ffmpeg pre-installed by default, ffmpeg even have a Windows version so this little tutorial should be directly applied on a Windows host with installed ffmpeg.
Convertion of a .flv file to .mp3 file for example is a real piece of cake to so do issue the command:
debian:~# ffmpeg -i input_file.flv -ab 128 -ar 44100 output_file.mp3
The few mmpeg options meaning is as follows:
-i (specifies input file)
-ab (Set the audio bitrate in bit/s 64k by default)
-ar (Set the audio sampling frequency (default = 44100 Hz).)
For more options checkout the ffmpeg help.
I found ffmpeg to be a bit slower than I expected. A 17 minutes .flv video file is converted to .mp3 for 38 seconds time.
Here is the textual output I got on my Debian Linux while extracting the flash video’s sound and converting it to mp3:
debian:~# time ffmpeg -i g7tvI6JCXD0.flv -ab 128 -ar 44100 output.mp3

When talking about conversions, another very useful application of ffmpeg is in case if you want to:
Extract Audio from online streams
Let’s say you have a favourite radio, you often listen and there are a podcast you want to capture for later listening, or just catch a few nice songs, using ffmpeg it’s a piece of cake by using the command like:
debian:~# ffmpeg -i http:///xxx.xxx.xxx.xxx/some -ab 128 -ar 44100 captured-radio-sound.mp3
The possible ways of use of ffmpeg is truly versatily, you can use it for instance if you have to convert some kind of audio or video format to another one I have given a very simple example of converting a .flv file to .avi and vice versa in my previous post

In my experience with many network Internet Service Providers by so far I’ve encountered a lot of DNS oddities and therefore surfing (web) and mail slowness.
It’s sometimes very irritating especially in cases, when I use my internet over Wireless public or university wireless networks.
In principle many of the Wireless routers which distribute the internet especially in organizations are badly configured and the slowness with DNS resolvings is an absolute classic.
If you haven’t encountered that slowness in opening web pages when connected from your University’s canteen, whether it’s fill with people for the lunch break, then I should say you’re really lucky!
My personal experience with this bad configured devices DNS services has been quite negative and every now and then I use to set and use public DNS servers like OpenDNS and Google DNS
Very often when I connect to a wireless network with my notebook running Debian Linux and the internet is too slow in opening pages I automatically set the Google or OpenDNS servers as a default DNS IP resolving servers.
1. DNS IP addresses of Google Public DNS are:
8.8.8.7
and
8.8.8.8
2. OpenDNS Public DNS servers has the IP addresses of:
208.67.222.222
208.67.222.220
I do set up and use the upper public DNS services addresses via the commands:
3. Set and use Google Public DNS services on my Linuxdebian:~# cp -rpf /etc/resolv.conf /etc/resolv.conf.orig
debian:~# echo "nameserver 8.8.8.7\n nameserver 8.8.8.8 \n" > /etc/resolv.conf;
I first create backu pof my resolv.conf under the name resolv.conf.orig just to make sure I can revert back to my old DNSes if I need them at some point.
If you prefer to use the OpenDNS services for some let’s say privacy reasons, you do it in the same manner as in the above commands, you only change the IP addresses. 4. Configure and use the OpenDNS public DNS services
debian:~# cp -rpf /etc/resolv.conf /etc/resolv.conf.orig
debian:~# echo "nameserver 208.67.222.222\n nameserver 208.67.222.220 \n" > /etc/resolv.conf;
Of course using Public DNS services has it’s disadvantages over the domain resolving speed up advantage.
One major issue is that Public DNS services are running on a top of a cloud and if you have red my previous article Cloud Computing a possible threat to users privacy and system administrator employment you might be agaist the idea of using a services which are powered by cloud.
The other primary concern is related to your SECURITY and a PRIVACY by using Public DNS networks, you risk that your Public DNS provider might use some DNS spoof techniques to mislead you and resolve you common domain names which usually resolve to let’s say 1.1.1.1 to let’s say 1.5.5.10
Even though this kind of practices on a side of a public DNS provider is not a likely scenario the possible implications of Public DNS providers using DNS forgery to fool you about domain names locations is a very serious issue.
As public DNS providers does contain again the good old philosophy of cloud computing embedded in themselves and they strive to become some kind of a standard which people might vote to adopt and use, the future implications of a wide adoption of Public DNS servers might be a terrible thing on internet users privacy!!!
Just think about a future scenario where we users of the Internet are forced to use a number of public DNS servers in order to use the Internet!
Usually a very huge companies are possessing the Public DNS services and do pay for the tech equipment required for building up the cluster clouds which provide the DNS services and therefore, if in the short future public DNS becomes a fashion and (God forbid!) a standard which shifts up the regular ISP DNS servers to resolve domains to IPs then it will be terrible.
The corporations which does own the Public DNS service/s might have a direct control over filtering and censoling information posted on any website on the internet.
Even worser if the world decides to adopt public DNS services somewhere in the future this means that large corporations owning the open dns cluster or clusters will be able to check each and every resolving made by any user on the net.
If you think closely such an information possessed by a company is not the best thing we want.
So let me close up this article, I’m not a fan and an evangelist who preaches the use of Public DNS services. Right on Contrary I do honestly hate the idea behind public DNS.
Nevertheless apart from my personal opinion I’m a practical person and using the public DNS servers every now and then when this will accelerate my access to the internet is still an option I do enjoy.
Maybe it’s time for a free software project (a tor like), which will provide users with an OpenDNS alternative which will run on hobbyist computers around the globe (just like with tor).
What’s rather funny is that the loud name OpenDNS is a big lie in reality OpenDNS is not opened it’s a company owned closed source service

1. First it’s necessery to have the mrtg debian package installed.
If it’s not installed then we have to install it:
debian-server:~# apt-get install mrtg
2. Second download the qmailmrtg source binary
To download the latest current source release of qmailmrtg execute:
debian-server:~# wget http://www.inter7.com/qmailmrtg7/qmailmrtg7-4.2.tar.gz
It’s a pity qmailmrtg is not available for download via debian repositories.
3. Third download the qmail.mrtg.cfg configuration file
debian-server~# wget http://www.pc-freak.net/files/qmail.mrtg.cfg
Now you have to put the file somewhere, usually it’s best to put it in the /etc/ directory.
Make sure the file is existing in /etc/qmail.mrtg.cfg
4. Untar compile and install qmailmrtg binary
debian-server:~# tar -xzvvf qmailmrtg7-4.2.tar.gz
...
debian-server:~# make && make install
strip qmailmrtg7
cp qmailmrtg7 /usr/local/bin
rm -rf *.o qmailmrtg7 checkq core
cc checkq.c -o checkq
./checkq
cc -s -O qmailmrtg7.c -o qmailmrtg7
qmailmrtg7.c: In function ‘main’:
qmailmrtg7.c:69: warning: incompatible implicit declaration of
built-in function ‘exit’
qmailmrtg7.c:93: warning: incompatible implicit declaration of
built-in function ‘exit’
qmailmrtg7.c:131: warning: incompatible implicit declaration of
built-in function ‘exit’
qmailmrtg7.c:137: warning: incompatible implicit declaration of
built-in function ‘exit’
5. Set proper file permissions according to the user you indent to execute qmailmrtg as
I personally execute it as root user, if you intend to do so as well set a permissions to
/etc/qmail.mrtg.cfg of 700.
In order to do that issue the command:
debian-server:~# chmod 700 /etc/qmail.mrtg.cfg
6. You will now need to modify the qmail.mrtg.cfg according to your needs
There you have to set a proper location where the qmailmrtg shall generate it’s html data files.
I use the /var/www/qmailmrtg qmailmrtg log file location. If you will do so as wellyou have to create the directory.
7. Create qmailmrtg html log files directory
debian-server:~# mkdir /var/log/qmailmrtg
8. Now all left is to set a proper cron line to periodically invoke qmailmrtg in order to generate qmail activity statistics.
Before we add the desired root’s crontab instructions we have to open the crontab for edit, using the command.
debian-server:~# crontab -u root -e
I personally use and recommend the following line as a line to be added to root’s crontab.
0-55/5 * * * * env LANG=C /usr/bin/mrtg /etc/qmail.mrtg.cfg > /dev/null
9. Copy index.html from qmailmrtg source directory to /var/log/qmailmrtg
debian-server:/usr/local/src/qmailmrtg7-4.2# cp -rpf index.html /var/log/qmailmrtg
10. Last step is to make sure Apache’s configuration contains lines that will enable you to access the qmail activity statistics.
The quickest way to do that in Debian running Apache 2.2 is to edit /etc/apache2/apache2.conf and add a directory Alias as follows
Alias /qmailmrtg/ "/var/www/qmailmrtg/"
Now after Apache restart /etc/init.d/apache2 restart
You should be now able to access the qmail mrtg qmail log statistics through your Apache’s default configured host.
For instance, assuming your default configured Apache host is domain.com. You’ll be able to reach the qmailmrtg statistics through an url like:
http://domain.com/qmailmrtg/
After I verified and ensured myself qmail mrtg is working correctly after all the above explained steps partook I wasn’t happy with some headlines in the index.html and the html tile of qmailmrtg,
so as a last step I manually edited the /var/www/qmailmrtg/index.html to attune it to my likings.
Here is a screenshot of the qmailmrtg web statistics in action.

Tell me which ideotic government would create a site based on php and would make the serverunder Windows?
Just Guess ours the Bulgarian ministry of Science and Knowledge has started a new site dedicated to helping graduating school pupils with the Future School-examinationthey have to make.
It's pretty easy to see that just observe:
jericho% telnet zamaturite.bg 80
Trying 212.122.183.208…
Connected to zamaturite.bg.

Just great our Bulgarian government spend money on buying proprietary software OS to run a Free Software based solution.
This example is pretty examplary of what our country looks like. Sad …
