Check server Internet connectivity Speedtest from Linux terminal CLI

Friday, August 7th, 2020

check-server-console-speedtest

If you are a system administrator of a dedicated server and you have no access to Xserver Graphical GNOME / KDE etc. environment and you wonder how you can track the bandwidth connectivity speed of remote system to the internet and you happen to have a modern Linux distribution, here is few ways to do a speedtest.
 

1. Use speedtest-cli command line tool to test connectivity


speedtest-cli is a tiny tool written in python, to use it hence you need to have python installed on the server.
It is available both for Redhat Linux distros and Debians / Ubuntus etc. in the list of standard installable packages.

a) Install speedtest-cli on Fedora / CentOS / RHEL
 

On CentOS / RHEL / Scientific Linux lower than ver 8:

$ sudo yum install python

On CentOS 8 / RHEL 8 user type the following command to install Python 3 or 2:

$sudo yum install python3
$ sudo yum install python2


On Fedora Linux version 22+

$ sudo dnf install python
$ sudo dnf install pytho3


Once python is at place download speedtest.py or in case if link is not reachable download mirrored version of speedtest.py on pc-freak.net here
 

$ wget -O speedtest-cli https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py
$ chmod +x speedtest-cli


Then it is time to run script speedtest-screenshot-linux-terminal-console-cli-cmd
To test enabled Bandwidth on the server

$ python speedtest-cli


b) Install speedtest-cli on Debian

On Latest Debian 10 Buster speedtest is available out of the box in regular .deb repositories, so fetch it with apt
 

# apt install –yes speedtest-cli


You can give now speedtest-cli a try with –bytes arguments to get speed values in bytes instead of bits or if you want to generate an image with test results in picture just like it will appear if you use speedtest.net inside a gui browser, use the –share option

speedtest-screenshot-linux-terminal-console-cli-cmd-options

2. Getting connectivity results of all defined speedtest test City Locations


Speedtest has a list of servers through which a Upload and Download speed is tested, to run speedtest-cli to test with each and every server and get a better picture on what kind of connectivity to expect from your server towards the closest region capital cities, fetch speedtest-servers.php list and use a small shell loop below is how:

For better readability you might want to add the ouput to a file or even put it to run periodically on a cron if you have some suspcion that your server Internet dedicated lines dies out to some general locations sometimes.
 

3. Testing UPlink speed with Download some big file from source location


In the past a classical way to test the bandwidth connectivity of your Internet Service Provider was to fetch some big file, Linux guys should remember it was almost a standard to roll a download of Linux kernel source .tar file with some test browser as elinks / lynx / w3c.
speedtest-screenshot-kernel-org-shot1 speedtest-screenshot-kernel-org-shot2
or if those are not at hand test connectivity on remote free shell servers whatever file downloader as wget or curl was used.
Analogical method is still possible, for example to use wget to get an idea about bandwidtch connectivity, let it roll below 500 mb from speedtest.wdc01.softlayer.com to /dev/null few times:

$ wget –output-document=/dev/null http://speedtest.wdc01.softlayer.com/downloads/test500.zip

$ wget –output-document=/dev/null http://speedtest.wdc01.softlayer.com/downloads/test500.zip

$ wget –output-document=/dev/null http://speedtest.wdc01.softlayer.com/downloads/test500.zip

# wget -O /dev/null –progress=dot:mega http://cachefly.cachefly.net/10mb.test ; date

To be sure you have a real picture on remote machine Internet speed it is always a good idea to run download of random big files on a certain locations that are well known to have a very stable Internet bandwidth to the Internet backbone routers.

4. Using Simple shell script to test Internet speed


Fetch and use speedtest.sh


wget https://raw.github.com/blackdotsh/curl-speedtest/master/speedtest.sh && chmod u+x speedtest.sh && bash speedtest.sh

5. Using iperf to test connectivity between two servers 

iperf is another good tool worthy to mention that can be used to test the speed between client and server.

To use iperf install it with apt and do on the server machine to which bandwidth will be tested:

# iperf -s 

On the client machine do:

# iperf -c 192.168.1.1 

where 192.168.1.1 is the IP of the server where iperf was spawned to listen.

6. Using Netflix fast to determine Internet connection speed on host


Fast

fast is a service provided by Netflix. Its web interface is located at Fast.com and it has a command-line interface available through npm (npm is a package manager for nodejs) so if you don't have it you will have to install it first with:

# apt install –yes npm

Note that if you run on Debian this will install you some 249 new nodejs packages which you might not want to have on the system, so this is useful only for machines that has already use of nodejs.

$ fast

     82 Mbps ↓


The command returns your Internet download speed. To get your upload speed, use the -u flag:

$ fast -u

   ⠧ 80 Mbps ↓ / 8.2 Mbps ↑

7. Use speedometer / iftop to measure incoming and outgoing traffic on interface


If you're measuring connectivity on a live production server system, then you might consider that the measurement output might not be exactly correct especially if you're measuring the Uplink / Downlink on a Heavy loaded webserver / Mail Server / Samba or DNS server.
If this is the case a very useful tools to consider to extract the already taken traffic used on your Incoming and Outgoing ( TX / RX ) Network interfaces
are speedometer and iftop, they're present and installable depending on the OS via yum / apt or the respective package manager.


To install on Debian server:

# apt install –yes iftop speedometer


The most basic use to check the live received traffic in a nice Ncurses like text graphic is with: 

# speedometer -r 


speedometer-check-received-transmitted-network-traffic-on-linux1

To generate real time ASCII art graph on RX / TX traffic do:

# speedometer -r eth0 -t eth0


speedometer-check-received-transmitted-network-traffic-on-linux

# iftop -P -i eth0

Getting Console and Graphical hardware system information on Linux with cpuinfo, neofetch, CPU-X (CPU-Z Unix alternative), I-nex and inxi

Tuesday, September 17th, 2019

getting-console-information-and-graphical-hardware-system-information-Linux-cpuinfo-neofetch-cpu-x-i-nex-1

Earlier I've wrote extensive article on how to get hardware information on Linux using tools such as dmidecode, hardinfo, lshw, hwinfo, x86info and biosdecode but there are few other hardware reporting tools for Linux worthy to mention that has been there for historical reasons such as cpuinfo as we as some new shiny ones such as neofetch (a terminal / console hardware report tool as well the CPU-X and I-Nex  which is Linux equivalent to the all known almost standard for Windows hardware detection CPU-Z worthy to say few words about.
 

1. cpuinfo

Perhaps the most basic tool to give you a brief information about your Processor type (model) number of Cores and Logical Processors is cpuinfo

I remember cpuinfo has been there since the very beginning on almost all Linux distributions's repository, nowadays its popularity of the days when the kings on the Linux OS server scenes were Slackware, Caldera OpenLinux and Redhat 6.0 Linux and Debian 3.0  declined but still for scripting purposes it is handy small proggie.

To install and run it in Debian  / Ubuntu / Mint Linux etc.:

aptitude install -y cpuinfo

/usr/bin/cpu-info

Linux-get-processor-system-info-in-console-cpu-info

2. neofetch

The next one worthy to install and check is neofetch (a cross-platform and easy-to-use system information
 command line script that collects your Linux system information and display it on the terminal next to an image, it could be your distributions logo or any ascii art of your choice.)

The cool thing about neofetch is besides being able to identify the System server / desktop hardware parameters, it gives some basic info about number of packages installed on the system, memory free and in use, used kernel and exact type of System (be it Dell PowerEdge Model XX, IBM eSeries Model / HP Proliant Model etc.

neofetch info generated on my home used Lenovo Thikpad T420

neofetch-OS-hardware-information-Linux-ascii-system-info-pcfreak-home-server
neofetch info from pc-freak.net running current machine

neofetch even supports Mac OS X and Windows OS ! 🙂

To install neofetch on Mac OS X:
 

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"


or via Mac ported packages using brew

brew install neofetch


neofetch-screenshot-from-Mac-OS-X

neofetch is even installable on Windows OS that has the scoop command line installer tool installer manager with below PowerShell code in cmd.exe (Command line):

powershell Set-ExecutionPolicy RemoteSigned -scope CurrentUser
iex (new-object net.webclient).downloadstring('https://get.scoop.sh')
scoop install git
scoop install neofetch

neofetch-microsoft-windows-hardware-command-line-report-tool-screenshot


By the way Scoop was quite a finding for me and it is pretty handy to install plenty of useful command line Linux / UNIX tools, such as curl, wget, git etc. in the same easy straight forward way as a standard yum or apt-get on Windows (without explicitly installing things as GnuWin and CygWin).
 

3. CPU-X graphical user interface hardware report Linux GUI alternative to Windows CPU-Z


The packages for CPU-X are a bit outdated and even though there are rpm packages for Fedora, OpenSuSE and .deb package for Debian for Debian, Ubuntu and ArchLinux (pacman), there is no up to date version for Debian 10 and the package builds distributed for different Linux distros are a bit outdated.

Thus to install CPU-X on any Linux distribution it is perhaps best to use the portable version (static binary) of CPU-X.
It is currently available on https://github.com/X0rg/CPU-X/releases

To install latest portable version of CPU-X

wget https://github.com/X0rg/CPU-X/releases/download/v3.2.4/CPU-X_v3.2.4_portable.tar.gz

mkdir CPU-X
cd CPU-X

tar -zxvvf CPU-X_v3.2.4_portable.tar.gz
-rwxr-xr-x yohan/users 4563032 2019-01-13 22:15 CPU-X_v3.2.4_portable.bsd64
-rwxr-xr-x yohan/users 5484968 2019-01-13 22:15 CPU-X_v3.2.4_portable.linux64

cp -rpf CPU-X_v3.2.4_portable.linux64 /usr/local/bin/
ln -sf /usr/local/bin/CPU-X_v3.2.4_portable.linux64 /usr/local/bin/cpu-x


Next run as superuser (root)
 

hipo@jeremiah:~$ su -c 'cpu-x'

As seen from below screenshots cpu-x reports a lot of concrete specific hardware data on:

  • Processor
  • Motherboard
  • Memory
  • System
  • Graphic card
  • Performance

cpu-x-cpu-cpu-z-alternative-linux-screenshot-CPU-info

cpu-x-cpu-cpu-z-alternative-linux-screenshot-caches-info

cpu-x-cpu-cpu-z-alternative-linux-screenshot-Motherboard-info

cpu-x-cpu-cpu-z-alternative-linux-screenshot-memory-info

cpu-x-cpu-cpu-z-alternative-linux-screenshot-system-info

cpu-x-cpu-cpu-z-alternative-linux-screenshot-graphics-info

CPU-X can be installed also on FreeBSD very easily by just installing from BSD port tree sysutils/cpu-x/
It is also said to work on other *BSDs, NetBSD, OpenBSD Unixes but I guess this will require a manual compilation based on FreeBSD's port Makefile.

4. I-Nex another GUI alternative to CPU-Z for UNIX / Linux

I-Nex is even more useful for general hardware reporting as it reports many hardware specifications not reported by CPU-X such as Battery type and Model Name  (if the hardware report is on a laptop), info on USB devices slots or plugged USB devices brand and specifications, the available Network devices on the system (MAC Addresses) of each of it, Installed and used drivers on Hard Disk (ATA / SATA / SCSI / SSD), HW Sector size, Logical Block size, HDD Sectors count and other specific Hard Drive data as well as information on available Audio (Sound Blaster) devices (HDA-Intel), used Codecs, loaded kernel ALSA driver, Video card used and most importantly indicators on Processor reported CPU (temperature).

To install I-nex

Go to https://launchpad.net/i-nex or any of the mirror links where it resides and install the respective package, in my case, I was doing the installation on Debian Linux, so fetched current latest amd64 package which as of moment of writting this article is i-nex_7.6.0-0-bzr977-20161012-ubuntu16.10.1_amd64.deb , next installed it with dpkg
 

dpkg -i i-nex_7.6.0-0-bzr977-20161012-ubuntu16.10.1_amd64.deb

As the package was depending on some other .deb packages, which failed to install to install the missing ones I had to further run
 

apt –fix-broken install

i-nex-cpu-info-linux-hardware-info-program

hre

I-Nex thermal indicators about CPU temperature on a Linux Desktop notebook

i-nex-gpu-info-linux-hardware-info-program

i-nex-mobo-info-linux-hardware-info-program

i-nex-audio-info-linux-hardware-info-program

i-nex-drivers-info-linux-hardware-info-program

i-nex-system-info-linux-hardware-info-program

i-nex-battery-info-linux-hardware-info-program

There are other Hardware identification report tools such as CUDA-Z that are useful to check if you have Nvidia Video Card hardware Installed on the PC to check the status of CUDA enabled GPUs, useful if working with nVidia Geforce, Quadro, Tesla cards and ION chipsets.

If you use it however be aware that CUDA-Z is not compatible with 3rd-party linux drivers for NVidia so make sure you have the current official Nvidia version.

5. Inxi full featured system information script

Inxi is a 10000 lines mega bash script that fetches hardware details from multiple different sources in /proc /sys and from commands on the system, and generates a beautiful looking console report that non technical users can read easily.

inxi-10-k-mega-bash-shell-script-reporting-on-installed-system-computer-hardware

inxi -Fx

inxi-report-on-installed-hardware-on-my-lenovo-thinkpad-home-laptop

Each of the pointed above tools has different method of collection of Hardware information from various resources e.g. – kernel loaded modules, dmesg, files like /proc/meminfo /proc/version /proc/scsi/scsi /proc/partitions.
Hence some of the tools are likely to report more info than otheres, so in case if some information you need regarding the system plugged in hardware is missing you can perhaps obtain it from another program. Most Linux distribution desktop provided GNOME package are including Hardinfo gui tool, but in many cases above mentioned tools are likely to add even more on info on what is inside your PC Box.
If you're aware of others tools that are useful not mentioned here please share it.

Check weather forecast from console (terminal) on GNU / Linux and FreeBSD howto

Friday, August 23rd, 2019

how to get weather forecast prognosis from command line text terminal / console on Linux and FreeBSD

Doing everything in Linux console / terminal is a question perhaps every Linux / BSD hacker wants to do as Graphical user interface and using web search or using Graphical Environment plugins is an unneded complexity + googling or duckduckgoing for weather to check your next vacation destination city has been more and more of a terrible experience (for me) as I'm not a big fan of using the OS in a GUI.
In that manner of thoughts, as a Linux console geek and hard core ASCII art fan. I was recently happy to find that  possible to check weather forecast in tty console or Linux terminal in a beautiful ascii art way easily through a Web wttr.in service – a web application weather forecast service that supports displaying the current and few days in future, weather forecast either in browser as a plain text or from the command line by simply accessing it with your favourite web access / transfer tool such as;
wget / curl or any of your favourite text browser elinks / lynx / w3m or if on *BSDs use fetch command.

Install Curl data transfer tool if it is not already


Wget is installed by default across most Linux distributions and fetch is present by default on BSDs, displaying it in text browser would perhaps be never used but if you decide to give it a try maybe try with elinks (to get colorful output), w3m and lynx will display a black and white results.

In case if you miss curl, install it:

On Debian distro

aptitude install -y curl


or Fedora

yum install -y curl


Of course to use wttr.in as it is Internet based Weather Forecast service the minimum you need to have is to have Internet connection to your Linux / BSD desktop computer.

Text based Weather Forecast Web App currently supports:

display the current weather as well as a 3-day weather forecast, split into morning, noon, evening and night

  • Temperature is displayed for morning, noon, evening and night (includes temperature range, wind speed and direction, viewing distance, precipitation amount and probability)
  • Provide results for Weather based on City / town / village location
  • Supports display of Moon Phases Forecast in calendar days
  • Supports multilingual names (Bulgarian Phonetic cyrillic / Russian and other exotic UTF-8 encodings such as Chineese and Japanese),  50+ languages are currently supported
  • Has ability for prognosis for hostname (domain) location based on an its IP GeoIP location on the Globe
  • Geographical locations / landmarks such as Lakes / Mountains etc. can be easily queried
  • Query results metrics could be configured, e.g. USCS units or EU and rest of world accepted ones (SI) metric
  • Displayed result could be either in ANSI (if from terminal / console / HTML if queried from browser or in PNG – if needed)

Where wttr.in could be useful ?

The best applications use, I can think of are for server (shell) / perl scripting automation purposes, it could be useful especially in TOO HOT, TOO, COLD, TOO WET location in Small and Middle sized Data Centers Green Energy (Sun Panel) Parks / Wind Energy situated Linux monitoring hosts to track possible problems of overheats or overcolding of servers due to abnormal excessive temperatures such as the ones we experienced this summer here All across in Europe or in too Cold DC locations such as heat locations Deserts in African Countries, Saudi Arabia or Chukotka or Siberia in Russia.
Other application is as a backup option to other normal Weather report services by PHP or Python scripts that fetch data, from multiple places.
Of course since this is a third party controlled service, the downtime is due to excessive connection requests, the service could get flooded and stopped working, but I guess for any Commercial use, wttr.in creator Igor Chubin would be happy to sell a specific crafted service for any end user candidates.


Here is few examples of the beautiful returned ASCII art formatted output of wttr.in.
 

1. Getting a three days Weather Forecast prognosis for city / town location

To get what is current weather in my current city of Living, Sofia Bulgaria just pass the city to the URL address

curl http://wttr.in/Sofia

text-console-wttr.in-Weather-forecast-Sofia-for-Linux

links http://wttr.in/Dobrich

curl-Linux-show--Dobrich-Weather-forecast-in-lynx-text-browser


Default links (Linux) www text browser produces ugly black and white

2. Displaying Weather forecast with wget

wget -O- -q http://wttr.in


getting-weather-forecast-on-linux-terminal-console-with-wget-command

If you're lazy you can even omit the http:// as wget will look for HyperText Transmission Protocol by itself

wget -O- -q wttr.in

3. Getting Forecast results for a Tourist Destination


Lets get the weather forecast for the popular tourist Bulgarian destination of the Seven Rila Lakes (near Rila Monastery), situated in the Rila Mountain BG.

curl http://wttr.in/Seven+Rila+Lakes

Console-terminal-Weather-forecast-Linux-Seven-Rila-Lakes

4. Display Forecast for a specific server IP


Displaying information on specific server IP address current situated in GeoIP database, of course could be not really true, as the IP could be just a Load Balancer a router that does NAT to some internal DMZ-ed location server, but anyways it is a cool feature.

Lets get information on what is the weather on Google Global's Public DNS server IP 8.8.8.8 so commonly used to guarantee a Windows and Linux Desktop client machines Internet connectivity.
 

curl wttr.in/@8.8.8.8

wttr.in-Linux-text--forecast-service-curl-screenshot Google Public DNS location weather forecast

5. Download PNG image picture from wttr.in service


Lets say you want to get a 3 days standard Weather forecast for the popular Black Sea Resort town in Bulgaria Pomorie (a beautiful sea city which has even a functioning 5 Monks Monastery Pomorie Monastery situated near sea coast)

curl http://wttr.in/Pomorie.png

8. Comparing two cities weather from command line


One useful use of wttr.in if you plan to travel from Location city A to Location city B is to compare the temperatures with a simple bash one liner script:

diff -Naur <(curl -s http://wttr.in/Sofia ) <(curl -s http://wttr.in/Beograd )

9. Using ansiweather command to get Weather Temperature / Wind / Humidity in one line beuatiful text


If you go and install answeather Linux package

apt-get install –yes ansiweather


You will get a shell script wrapper with ANSI colors and Unicode symbols support. Weather data comes from OpenWeatherMap, this is useful if wttr.in is not working due to some URL malfunction (due to service is DoS-ed) etc.

ansiweather -l Atina

ansiweather-Atina-weather-forecast-result-linux-text-console

Lets use ansiweather to print the weather prognosis for upcoming 5 days for near port of Burgas, BG
 

ansiweather -F -l Burgas

ansiweather-print-weather-forecast-prognosis-for-5-days-in-Linux-text-terminal

10. Get all Weather current forecast for each Capital in the world


You can download and use this simple plain text file list of All Country Capitals in the World (country-capitals-all-world.txt) with ansiweather and a bash loop to get displayed each and every current day Weather Forecast in the World, here is how:

while read line; do ansiweather -l $line; sleep 3; done < country-capitals-all-world.txt


ansiweather-all-countires-capitals-result

As you can see some of the very exotic third world capitals does not return data so 'ERROR: Cannot fetch weather data' is returned.


You can also substitute ansiweather with curl wttr.in/$line to do get the beautiful ASCII art 3 days weather forecast via wttr.in

while read line; do curl http://wttr.in/$line; sleep 3; done < country-capitals-all-world.txt


I'll be happy to know other nice ASCII Art supporting Web service to enjoy from text terminal on Linux (nomatter useful or) just funny joyful prank maniacal pranks such as Watching text ASCII version remake of Star Wars Classic Movie by simply telnetting to towel.blinkenlights.nl (if you haven't so just telnet and enjoy the streamed ASCIIs ! 🙂

How to use wget and curl via HTTP Proxy server / How to set a HTTPS proxy server on a bash shell on Linux

Wednesday, January 27th, 2016

linux-ssl-proxy-configuration-from-command-line-with-wget-and-curl-howto

I've been working a bit on a client's automation, the task is to automate process of installations of Apaches / Tomcats / JBoss and Java servers, so me and colleagues don't waste too
much time in trivial things. To complete that I've created a small repository on a Apache with a WebDav server with major versions of each general branch of Application servers and Javas.
In order to access the remote URL where the .tar.gz binaries archives reside, I had to use a proxy serve as the client runs all his network in a DMZ and all Web Port 80 and 443 HTTPS traffic inside the client network
has to pass by the network proxy.

Thus to make the downloads possible via the shell script, writting I needed to set the script to use the HTTPS proxy server. I've been using proxy earlier and I was pretty aware of the http_proxy bash shell
variable thus I tried to use this one for the Secured HTTPS proxy, however the connection was failing and thanks to colleague Anatoliy I realized the whole problem is I'm trying to use http_proxy shell variable
which has to only be used for unencrypted Proxy servers and in this case the proxy server is over SSL encrypted HTTPS protocol so instead the right variable to use is:
 

https_proxy


The https_proxy var syntax, goes like this:

proxy_url='http-proxy-url.net:8080';
export https_proxy="$proxy_url"

how-to-set-https_proxy_url-on-linux-freebsd-openbsd-bsd-and-unix-from-terminal-console

Once the https_proxy variable is set  UNIX's wget non interactive download tool starts using the proxy_url variable set proxy and the downloads in my script works.

Hence to make the different version application archives download work out, I've used wget like so:
 

 wget –no-check-certificate –timeout=5 https://full-path-to-url.net/file.rar


For other BSD / HP-UX / SunOS UNIX Servers where  shells are different from Bourne Again (Bash) Shell, the http_proxy and  https_proxy variable might not be working.
In such cases if you have curl (command line tool) is available instead of wget to script downloads you can use something like:
 

 curl -O -1 -k –proxy http-proxy-url.net:8080 https://full-path-to-url.net/file.rar

The http_proxy and https_proxy variables works perfect also on Mac OS X, default bash shell, so Mac users enjoy.
For some bash users in some kind of firewall hardened environments like in my case, its handy to permanently set a proxy to all shell activities via auto login Linux / *unix scripts .bashrc or .bash_profile that saves the inconvenience to always
set the proxy so lynx and links, elinks text console browsers does work also anytime you login to shell.

Well that's it, my script enjoys proxying traffic 🙂
 

MobaXTerm: A good gnome-terminal like tabbed SSH client for Windows / Windows Putty Tabs Alternative

Wednesday, November 13th, 2013

Mobaxterm ssh client putty MS Windows alternative with tabs suitable for ex linux users

mobaxterm with tabbed ssh connections screenshot best putty windows ssh client alternative now

Last 10+ years I worked on GNU / Linux as Desktop. Last 7 years most of my SSH connections were managed from GNOME and I'm quite used to gnome-terminal ssh tabbing. In my new Employee Hewlett Packard. I'm forced to work on Microsoft Windows 7 and thus I used for a month or so Putty and Kitty fork from version 0.63 of PuTTY advertising itself as the best telnet / SSH client in the world. Both of the two lack tabbing and have interface which is pretty unfamiliar to me. As I'm so used to using native UNIX terminal. Fortunately a colleague of mine Ivelin was using an SSH client called MobaXTerm which very much did emulation similar to my favourite gnome-terminal. MobaXterm is not free software / open source app but this doesn't matter so much to me as anyways I'm running a non-free Win OS on my desktop. What makes MobaXterm so attractive is its rich functionality (cosmic years infront of Putty).

Here is website description of MobaXterm quoted from its website:

MobaXterm is an enhanced terminal for Windows with an X11 server, a tabbed SSH client and several other network tools for remote computing (VNC, RDP, telnet, rlogin). MobaXterm brings all the essential Unix commands to Windows desktop, in a single portable exe file which works out of the box.

Overall list of features MobaXterm offers are;

  •     multitab terminal with embedded Unix commands (ls, cd, cat, sed, grep, awk, rsync, wget, …)

  •     embedded X11 server for easily exporting your Unix/Linux display

  •     a session manager with several network utilities: SSH, RDP, VNC, Telnet, Rlogin, FTP, SFTP and XDMCP

  •     passwords management for SSH, RDP, VNC, SFTP (on demand password saving)

  •     easy graphical file transfer using drag and drop during SSH sessions

  •     advanced SSH tunnels creation tool (graphical port forwarding builder)

  •     tasks automation using scripts or macros

Mobaxterm is portable just like Putty so its useful to use on HOP stations to servers like used in big companies like HP. Featured embedded Unix commands (e.g., ls, cd, cat, sed, grep, awk, rsync, wget) gives a feeling like you're working on pure Linux console making people addicted to Linux / BSD quite confortable. Some other very useful terminal emulator functions are support for anti-aliasing session manager (save / remember passwords for ssh sessions in Crypted format so much missing in Putty) and it even supports basic macros.
Basic UNIX commands embedded in MobaXterm are taken and ported from Cygwin projectLinux-like environment for Windows making it possible to port software running on POSIX systems (such as Linux, BSD, and Unix systems) to Windows. A very cool think is also MobaXterm gives you a Linux like feel of console navigation in between basic files installed from Cygwin. Some downside I found is program menus which look at first glimpse a bit confusing especially for people used to simplicity of gnome-terminal. Once logged in to remote host via ssh command the program offers you to log you in also via SFTP protocol listing in parallel small window with possibility to navigate / copy / move etc. between server files in SFTP session which at times is pretty useful as it saves you time to use some external SFTP connector tools like  WinSCP.

From Tools configuration menu, there are few precious tools as well;
         – embedded text editor MobaTextEditor
         – MobaFoldersDiff (Able to show diffeernces between directories)
         – AsciiTable (Complete List of Ascii table with respective codes and characters)
         – Embedded simple Calculator
         – List open network ports – GUI Tool to list all open ports on Windows localhost
         – Network packets capture – A Gui tool showing basic info like from UNIX's tcpdump!
         – Ability to start quickly on local machine (TFTP, FTP, SFTP / SSH server, Telnet server, NFS server, VNC Server and even simple implementation of HTTP server)

Mobaxterm list of tools various stuff

Below are few screenshots to get you also idea about what kind of configuration MobaXterm supports

mobaxterm-putty-alternative-for-windows-configuration-display-screenshot
MobaXTerm Microsoft Windows ssh client configuration misc menu screenshot
To configure and use Telnet, RSH, RDP, VNC, FTP etc. Sessions use the Sessions tab on top menu.

One very handy thing is MobaXterm supports export of remote UNIX display with no requirement to install special Xserver like already a bit obsolete Xming – X server for Windows.
The X Display Manager Control Protocol (XCMCP) is a key feature of the X11 architecture. Together with XDMCP, the X network protocol allows distributed operation of the X server and X display manager. The requesting X server runs on the client (usually as an X terminal), thus providing a login service, that why the X server ported to MobaXterm from Cygwin also supports XDMCP. If, for example, you want to start a VNC session with a remote VNC server, all you have to do is enter the remote VNC server’s IP address in the VNC area; the default VNC port is already registered.

Accessing the remote Windows server via RDP (Remote Desktop Protocol) is also a piece of cake. Once you establish a session to RDP or other Proto it is possible to save this session so later you just choose between session to access. The infamous (X11 Port Forwarding) or creation of SSH encrypted tunnels between hosts to transfer data securily or hide your hostname is also there.

MobaXterm is undoubtedly a very useful and versatile tool. Functionally, the software is well mannered, and Windows users who want to sniff a little Linux/Unix air can get a good idea of how Linux works. A closer look reveals that anything you can do with MobaXterm can be achieved directly with freely available tools (Cygwin) and Unix tools ported from Cygwin. However, although Cygwin provides a non-Posix environment for Windows, it doesn’t offer a decent terminal, which is one thing Moba-Xterm has going for it.

Admittedly, in pure vanilla Cygwin, you can start an X server automatically and then use xterm, but xterm lacks good-quality fonts, whereas MobaXterm conveniently lets you integrate a font server.

Adding Teamviewer to auto start on Linux GNOME login

Friday, February 1st, 2013

Administrating Linux via graphical interface is not common, however sometimes it is necessery. There are plenty of ways to remotely administrate with GUI Linux. You can connect to remote Xserver and launch X session via xinit, connect via (Gnome Display Manager) GDM, use nomachine NX server / client (if you're on slow connection line) or use the good old Teamviewer.

As Teamviewer works pretty well on both Windows and Linux in last times I like using teamviewer as a standard. It is freeware and it often disconnects with the annoying Trial message, but in general for managing something quick on remote desktop it is nice.

To use teamviewer, you need to have it installed on the Linux host via deb or rpm:

Whether on Debian / Ubuntu use:

# wget http://www.teamviewer.com/download/version_8x/teamviewer_linux_x64.deb
.....
# dpkg -i teamviewer_linux_x64.deb
...
....

 

On Fedora, CentOS, RHEL run:

# wget -q http://www.teamviewer.com/download/teamviewer_linux.rpm
# rpm -Uvh teamviewer_linux.rpm
.....

Once package is installed teamviewer is installed in /opt/teamviewer/* there is a tiny wrapper run script in /usr/bin/teamviewer – evoking TeamViewer to be run via wine emulation.

Hence to make TeamViewer start on certain user GNOME login the script has to run on GNOME user login session.
In both GNOME 2 and GNOME 3 what is run on user login is managed through gnome-session-properties thus /usr/bin/teamviewer has to be set to run through gnome-session-properties (to run it press ALT+F2 or type it directly in gnome-terminal)

user@linux:~$ gnome-session-properties

A window like in below screenshot pops up and from there Add TeamViewer.

Adding Teamviewer to auto start on Linux Debian Fedora CentOS GNOME non privileged user

To be able to later connect via a Remote host with another TeamViewer peer launch TeamViewer and configure permanent password through menus:

Extras -> Options -> Security

teamviewer extras options security configuring teamviewier permanent password for ID

All left is to write down your Teamviewer Remote Connect ID and permanent set password

Teamviewer remote connect ID screnshot Linux

After next succesful GNOME login teamviewer will just pop-up. Enjoy

New version of Teamviewer 8 beta for GNU / Linux is out

Monday, January 28th, 2013

I had to login to a Windows host, after a friend handed in his Teamviewer ID and pass. I tried connecting few times and connection failed every time. It was not very likely it is a network problem as I have pretty good internet bandwidth here. I ask him what is his teamviewer, release and it turned out he is using TeamViewer 8. Just few months ago I've updated my teamviewer from TV 6 to TV 7 after finally Teamviewer 7 was launched for Linux. I check immediately TeamViewer website, but this time (TeamViewer GmbH – the vendor company of TV) has launched TV 8 for Linux in parallel with launching TV 8  for Windows.

Of course like often in Linux it is not all perfect TeamViewer 8 version is still in beta testing stage. I've downloaded and updated my (64 bit) teamviewer 7 to teamviewer 8 using the Deb binary, i.e.:

# wget http://www.teamviewer.com/download/version_8x/teamviewer_linux_x64.deb
.....
# dpkg -i teamviewer_linux_x64.deb
...
....

Just like previous TeamViewer, releases, the program launches via wine, so teamviewer_linux_x64.deb depends on working wine Windows emulator.
There are minor difference in graphic interface but no so significant changes from previous release.

TeamViewer beta 8 ver on Debian GNU linux screenshot

I used it to connect to remote Windows 8 host and experienced random issues with typing some characters from keyboard remotely, though I'm not sure if this was due to some bug of the TV 8 beta release or it is due to fact the Win host was infested with viruses.
Just for some convenience if I further need it, I've also made mirror of 32 bit TeamViewer 8 beta here and 64 bit TeamViewer 8 beta mirror here.

How to clean QMAIL mail server filled Queue with spam mail messages

Friday, June 8th, 2012

Sys Admins managing QMAIL mail servers know, often it happens QMAIL queue gets filled with unwanted unsolicated SPAM e-mails due to a buggy WEB PHP / Perl mail sendingform or some other odd reason, like too many bouncing messages ,,,,

For one more time I’ve experienced the huge SPAM destined mails queue on one QMAIL running on Debian GNU / Linux.

= … Hence I needed to clean up the qmail queue. For this there is a little tool written in PERL called qmhandle

A+) Download qmhandle;

Qmhandle’s official download site is in SourceForge

I’ve made also a mirror copy of QMHandle here

qmail-server:~# cd /usr/local/src
qmail-server:/usr/local/src# wget -q https://pc-freak.net/files/qmhandle-1.3.2.tar.gz

B=) STOP QMAIL
As it is written in the program documentation one has to be very careful when cleaning the mail queue. Be sure to stop qmail with qmailctl or whatever script is used to shutdown any mail sever in progress operations, otherwise there is big chance the queue to mess up badly .

C#) Check extended info about the mail queue:

How to copy / clone installed packages from one Debian server to another

Friday, April 13th, 2012

1. Dump all installed server packages from Debian Linux server1

First it is necessery to dump a list of all installed packages on the server from which the intalled deb packages 'selection' will be replicated.

debian-server1:~# dpkg --get-selections \* > packages.txt

The format of the produced packages.txt file will have only two columns, in column1 there will be the package (name) installed and in column 2, the status of the package e.g.: install or deinstall

Note that you can only use the –get-selections as root superuser, trying to run it with non-privileged user I got:

hipo@server1:~$ dpkg --set-selections > packages.txt
dpkg: operation requires read/write access to dpkg status area

2. Copy packages.txt file containing the installed deb packages from server1 to server2

There is many way to copy the packages.txt package description file, one can use ftp, sftp, scp, rsync … lftp or even copy it via wget if placed in some Apache directory on server1.

A quick and convenient way to copy the file from Debian server1 to server2 is with scp as it can also be used easily for an automated script to do the packages.txt file copying (if for instance you have to implement package cloning on multiple Debian Linux servers).

root@debian-server1:~# scp ./packages.txt hipo@server-hostname2:~/packages.txt
The authenticity of host '83.170.97.153 (83.170.97.153)' can't be established. RSA key fingerprint is 38:da:2a:79:ad:38:5b:64:9e:8b:b4:81:09:cd:94:d4. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '83.170.97.153' (RSA) to the list of known hosts. hipo@83.170.97.153's password:
packages.txt

As this is the first time I make connection to server2 from server1, I'm prompted to accept the host RSA unique fingerprint.

3. Install the copied selection from server1 on server2 with apt-get or dselect

debian-server2:/home/hipo# apt-get update
...
debian-server2:/home/hipo# apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
debian-server2:/home/hipo# dpkg --set-selections < packages.txt
debian-server2:/home/hipo# apt-get -u dselect-upgrade --yes

The first apt-get update command assures the server will have the latest version of the packages currently installed, this will save you from running an outdated versions of the installed packages on debian-server2

Bear in mind that using apt-get sometimes, might create dependency issues. This is depending on the exact package names, being replicated in between the servers

Therefore it is better to use another approach with bash for loop to "replicate" installed packages between two servers, like so:

debian-server2:/home/hipo# for i in $(cat packages.txt |awk '{ print $1 }'); do aptitude install $i; done

If you want to automate the questioning about aptitude operations pass on the -y

debian-server2:/home/hipo# for i in $(cat packages.txt |awk '{ print $1 }'); do aptitude -y install $i; done

Be cautious if the -y is passed as sometimes some packages might be removed from the server to resolve dependency issues, if you need this packages you will have to again install them manually.

4. Mirroring package selection from server1 to server2 using one liner

A quick one liner, that does replicate a set of preselected packages from server1 to server2 is also possible with either a combination of apt, ssh, awk and dpkg or with ssh + dpkg + dselect :

a) One-liner code with apt-get unifying the installed packages between 2 or more servers

debian-server2:~# apt-get --yes install `ssh root@debian-server1 "dpkg -l | grep -E ^ii" | awk '{print $2}'`
...

If it is necessery to install on more than just debian-server2, copy paste the above code to all servers you want to have identical installed packages as with debian-server1 or use a shor for loop to run the commands for each and every host of multiple servers group.

In some cases it might be better to use dselect instead as in some situations using apt-get might not correctly solve the package dependencies, if encountering problems with dependencies better run:

debian-server2:/home/hipo# ssh root@debian-server1 'dpkg --get-selections' | dpkg --set-selections && dselect install

As you can see using this second dselect installed "package" mirroring is also way easier to read and understand than the prior "cryptic" method with apt-get, hence I personally think using dselect method is a better.

Well that's basically it. If you need to synchronize also configurations, either an rsync/scp shell script, should be used with all defined server1 config files or in case if a cloning of packages between identical server machines is necessery dd or some other tool like Norton Ghost could be used.
Hope this helps, someone.

How to run your Own / Personal Domain Web WHOIS service in a minute with SpeedyWHOIS

Thursday, April 5th, 2012

Running your own personal WHOIS service speedy whois in browser screenshot

I've been planning to run my own domain WHOIS service, for quite sime time and I always postpone or forgot to do it.
If you wonder, why would I need a (personal) web whois service, well it is way easier to use and remember for future use reference if you run it on your own URL, than wasting time in search for a whois service in google and then using some other's service to get just a simple DOMAIN WHOIS info.

So back to my post topic, I postpopned and postponed to run my own web whois, just until  yesterday, whether I have remembered about my idea to have my own whois up and running and proceeded wtih it.

To achieve my goal I checked if there is free software or (open source) software that easily does this.
I know I can write one for me from scratch, but since it would have cost me some at least a week of programming and testing and I didn't wanted to go this way.

To check if someone had already made an easy to install web whois service, I looked through in the "ultimate source for free software" sourceforge.net

Looking for the "whois web service" keywords, displayed few projects on top. But unfortunately many of the projects sources was not available anymore from http://sf.net and the project developers pages..
Thanksfully in a while, I found a project called SpeedyWhois, which PHP source was available for download.

With all prior said about project missing sources, Just in case if SpeedyWhois source  disappears in the future (like it probably) happened with, some of the other WHOIS web service projects, I've made SpeedyWhois  mirror for download here

 
Contrary to my idea that installing the web whois service might be a "pain in the ass", (like is the case  with so many free software php scripts and apps) – the installation went quite smoothly.
 
To install it I took the following 4 steps:
 
1. Download the source (zip archive) with wget 
 
# cd /var/www/whois-service;
/var/www/whois-service# wget -q https://pc-freak.net/files/speedywhois-0.1.4.zip
 
2. Unarchive it with unzip command 
 
 
/var/www/whois-service# unzip speedywhois-0.1.4.zip
3. Set the proper DNS records

My NS are using Godaddy, so I set my desired subdomain record from their domain name manager.
 

4. Edit Apache httpd.conf to create VirtualHost
 
This step is not mandatory, but I thought it is nice if I put the whois service under a subdomain, so add a VirtualHost to my httpd.conf
 
The Virtualhost Apache directives, I used are:
 
<VirtualHost *:80>
        ServerAdmin hipo_aT_pc-freak.net
        DocumentRoot /var/www/whois-service
        ServerName whois.pc-freak.net
        &lt;Directory /var/www/whois-service
        AllowOverride All
        Order Allow,Deny
        Allow from All
        </Directory>
</VirtualHost>
 
Onwards to take effect of new Webserver configs, I did Apache restart
 
# /usr/local/etc/rc.d/apache2 restart
 
Further on You can test whois a domain using my new installed SpeedyWHOISWeb WHOIS service  on http://whois.pc-freak.net
Whenever I have some free time, maybe I will work on the code, to try to add support for logging of previous whois requests and posting links pointing to the previous whois done via the web WHOIS service on the main whois page.
 
One thing that I disliked about how SpeedyWHOIS is written is, if there is no WHOIS information returned for a domain request (e.g.) a:
 
# whois domainname.com
 
returns an empty information, the script doesn't warn with a message there is no WHOIS data available for this domain or something.
 
 
This is not so important as this kind of behaviour of 'error' handling can easily be changed with minimum changes in the php code.
If you wonder, why do I need the web whois service, the answer is it is way easier to use.
I don't have more time to research a bit further on the alternative open source web whois services, so I would be glad to hear from anyone who tested other web whois service that is free comes under a FOSS license.
In the mean time, I'm sure people with a small internet websites like mine who are looking to run their OWN (personal) whois service SpeedyWHOIS does a great job.
