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)

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

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.

KRaptor a Raptor free software (open source) arcade game clone for GNU / Linux

Monday, January 30th, 2012

Kraptor is another Raptor Shadow of Death free software, open source clone arcade game for GNU/Linux, DOS and Windows (98, XP etc.).

KRaptor main menu game screenshot Linux Debian Squeeze

The game is not under active development anymore since 2004. Kraptor features a powerful engine for creating quickly 2D shooter games, so the game should be a good learning curve for people interested into creation of arcade game shooter games.

The game just like Rafkill is built upon DUMB sound engine.
The game intro is quite entertaining 😉 The intro plays one by one the text:

Near Future:
Blobalization
Imperalizm
Corporations
Megalomaniacs
Money and Power. Slaves of the New Millenium!

KRaptor Bill gates like looking oppressor

After years of oppression, the slaved people of the world have raised against their masters. You, has a mercenary pilot, has been
contacted by the popular rebellion to fight against the forces of oppression.

In the morning, you jump into your cockpit and start up the engines. It's time to get airborne and start the attack. Get ready to
scramble the scum hired by the masters. Murder for freedom is the only way, you're on a mission, don't defraud us...

Like Rafkill, Kraptor is one man masterpiece created by a free software Argentinean geek known under the Kronoman artistic pseudonim. The game is really incredible for a one man work … a true masterpiece.
The game is licensed under MIT License.

Even though Kraptor is older game than Rafkill, the design is more resembling the original Raptor game. The game music is high quality stereo. Besides that music and fx sound effects are quite awesome. After each level you have a Raptor like weapons "blackmarket", where you can buy new weapons, recharge ship energy, upgrade ship etc.
The blackmarket implementation part of the game is probably the worst moment in the game along with the game menus (in my view).
Talking about graphics Kraptor supports really high number of resolutions ranging from 320×240 to 1280×1024! 640×480 is the standard resolution in which the game is running.

Kraptor raptor like Linux game plasma gun debian screenshot

Something I really like in the game is the number of multiple weapons your ship uses during play. Even if played in Easy mode it is taught.

There are game Saves after each level, so thanksfully you don't have to start again from zero once death.
At the end of each level there is a huge bad BOSS you have to destroy ;).
Kraptor the boss Debian GNU / linux

Installing Kraptor on Debian / Ubuntu and deb derivatives is with:

debian:~# apt-get install kraptor

On most rpm based Linux distributions, you can install the game by converting the deb package to rpm with alien or by building from source from Kraptor's sourceforge page

Its interesting the game name e.g. Kraptor is also a death / grind metal band name, (Maybe Kronoman is metalhead big fan of Kraptor and that's how he came up with the playful name. For all the old school game addicts there is the joystick support. I've tested it with my Genius analogous joystick and it works fine.

The game is lacking .desktop gnome definition and after once installed it only appears through Debian (section) GNOME menus and not in Applications -> Games :

Applications -> Debian -> Games -&act; Action -&t; Kraptor

Just like Rafkill on Debian the game exacutable binary is located in /usr/games/kraptor . Also like with the Rafkill case when launched the game has troubles with choppy sound and music caused by the stupid buggy! pulseaudio

Analogously like with Rafkill's case, the work around to the problematic music en sound is to use a little bash shell script like:

#!/bin/bash
pulseaudio -k;
/usr/games/kraptor
pulseaudio --start;

You can dowload Kraptor fix sound issues wrapper here

To install it on your Debian / Ubuntu and hence make the game sound play good issue with root:

debian:~# cd /usr/bin
debian:/usr/bin# wget http://www.pc-freak.net/bshscr/kraptor.wrapper.sh
...
debian:/usr/bin:# chmod +x kraptor.wrapper.sh
debian:/usr/bin:# mv kraptor.wrapper.sh kraptor

 

RafKill Raptor Free Software (Open Source) clone for GNU/Linux

Saturday, January 28th, 2012

I've earlier blogged on playing Apogee's Raptor Shadows of Death arcade on GNU / Linux with dosbox

All the old school raptor addicts will be interested to hear Kazzmir (Jon Rafkind) a free software devotee developer has created a small game resembling many aspects of the original Raptor arcade game.
The game is called Rafkill and is aimed to be a sort of Raptor like fork/clone.
Originally the game was also named Raptor like the DOS game, however in year 2006 it was changed to current Rafkill in order to avoid legal issues with Apogee's Raptor.

The game is not anymore in active development, the latest Rafkill release is from January 2007, anyhow even for the 2012 it is pretty entertaining. The sound and music are on a good level for a Linux / BSD shoot'em'up free software game . The graphics are not of a top quality and are too childish, but this is normal, since the game is just one man masterpiece.

Rafkill Level 1 Debian GNU/Linux

Rafkill is developed in C/C++ programming language, the game music engine it uses is called DUMB (Dynamic Universal Bibliotheque). By the way DUMB library is used for music engine in many Linux arcade games. DUMB allows the Linux game developer to develop his game and play a music files within different game levels in "tracked" formats like mod, s3m, xm etc.

The game is available in compiled form for almost all existent GNU/Linux distributions, as well as one can easily port it as it is open source.

To install Rafkill on Debian, Ubuntu, Xubuntu and Linux Mint en other Debian based distros

root@debian:~# apt-get install rafkill

Installing on Fedora and other rpm based is with yum

debian:~# apt-get install rafkill
...

Once rafkill is installed, in order to start it on Debian the only way is using the rafkill (/usr/bin/rafkill) command. It appears the deb package maintainer did not wrote a gnome launcher file like for example /usr/share/applications/rafkill.desktop
Just to explain for all the GNOME noobs, the .desktop files are a description file GNOME reads in order to understand where exactly to place certain application in the (Gnome Applications, Places, System …) menu panel.

Even though it miss the .desktop, it is launchable via Applications menu under the Debian section e.g. to open it from the GNOME menus you will have to navigate to:

Applications -> Debian -> Games -> Action -> Rafkill

This "shortcut" to launch the game is quite long and hard to remember thus it is handy to directly launch it via xterm:

hipo@debian:~$ rafkill

Rafkill raptor like native Linux game main menu screenshot Debian GNU / Linux Squeeze

or by pressing ALT+F2 and typing rafkill :

Rafkill Linux game gnome launcher screenshot

Rafkill Debian Linux Level 5 power weaponscreenshot

Starting the game I got some really ugly choppy music / sound issues.
My guess was the fizzling sounds were caused by some bug with the sound portions streamed through pulseaudio sound system.
To test if my presume is correct, stopped pulseaudio and launched rafkill once again:

hipo@debian:~$ pulseaudio -k
hipo@debian:~$ rafkill

This way the game was counting on ALSA to process sound en the sound was playing perfectly fine.

I solved this problem through small wrapper shell script. The script did kill pulseaudio before launching rafkill and that way solve gchoppy sound issues, once the game execution is over the script starts pulseaudio again in order to prevent all other applications working with pulseaudio.

Finally, I've placed the executable script in /usr/bin/rafkill :

Here is the script:

#!/bin/bash
pulseaudio --kill
/usr/games/rafkill
pulseaudio --start

You can download rafkill.wrapper.sh here
Or write in root terminal:

debian:~# cd /usr/bin
debian:/usr/bin:# wget http://www.pc-freak.net/bshscr/rafkill.wrapper.sh
debian:/usr/bin:# mv http://www.pc-freak.net/bshscr/rafkill.wrapper.sh rafkill
debian:/usr/bin:# chmod +x rafkill

Interesting in Ubuntu Linux, rafkill music is okay and I suppose the bug is also solved in newer Linux distributions based on Ubuntu. Probably the Debian Squeeze pulseaudio (0.9.21-4) package version has a bug or smth..

After the change the game music will be playing fine and the game experience is cooler. The game is hard to play. Its really nice the game has game Saves, so once you die you don't have to start from level 1.

  I've seen rafkill rolling around on freebsd.org ftps under the ubuntu packages pool, which means rafkill could probably be played easily on FreeBSD and other BSDs.

Enjoy the cool game 😉

Little Registry Cleaner (Free Software / Open Source Windows XP Registry Cleaner)

Little Registry Cleaner - Free and Open Source Software Windows XP Registry cleaner / Alternative to Registry Booster
Have you ever wondered, if there is a free (open source) software that could fix Windows XP registry irregularities e.g. (obsolete or unwanted items that build up in the registry over time.)?

I did not either until now, however when I had to fix, few Windows XP computers which was not maintained for a long time fixing the Windows registry was necessery to make the sluggerish computers improve their overall stability and performance.

The reasons of the slowness in computers who run for a long time by users who does not have a "computer culture" are obvious.
Windows programs which has incorrectly placed registry records withint the Windows registry database, Programs which on Uninstall / Removal left behind a lot of registry records just to hang around because of impotent (coders), or records created on purpose on program uninstall to intentionally further track the user behavior etc.
Other reasons why Windows registry gots bloated with time, are due to Malware or polymorphic Viruses which load them selves everytime on Windows load using some obscure registry records.

Though I'm not a big proprietary software lover still my job as a system administrator , enforces me to fix some broken Windowses.
I haven't fixed Windows machines for a long time, so my memories on programs that clean up registry are from my young years.

The software, I've used before to fix Windows 2000 / XP Registry was:

1. Registry Booster

From my current perspective of a free software hobbyist / evangelist it was important for me to clean up the Windows PCs with a program that is Free or Open Source Software.
When I'm asked to fix some Windows computer I always do my best to make most of the programs that roll on the PC to be FOSS.

Using FOSS instead of downloading from torrents, some cracked software has multiple benefits.

1. Usually Free Software is more stable and more robust2. FOSS software for Windows usually does not come with Malware / Spyware as many of the cracked proprietary software

3. Free and Open Source Programs are simplistic in interface and way of use

A bit of research if there is a Free (Open Source) Software immediately lead me to a program called Little Registry Cleaner
You can see a screenshot of the program in the beginning of the article, the program is very easy to install and use and uses some .NET framework classes so right before installing it installs .NET library (code).

The use results of Little Registry Cleaner were amazing. Even though it is a free software the program found and fixed more registry problems than its competitor Windows Registry Booster! 😉
 

Frogatto & Friends – One of the TOP 10 Arcade Free Software & Open Source Games for GNU / Linux and FreeBSD

Friday, December 16th, 2011

Frogatto old-school 2d jump and run free software game for GNU / Linux and FreeBSD
1. Frogatto & Friends – Is an Indian Free Software (Open Source) game in the spirit of old-school jump’en runs like Commander Keen, Prehistoric, Jazz Jack Rabbit

The game is really entertaining, the graphics looks approximately nice, the music is awesome, the gamelplay is good even though after some point in the game the moment with “where should I go now, I can’t find exit” comes through and it gets boring.

Generally if you compare with all the existing jump and run arcade games free software games available for Linux and FreeBSD the game will definetely arrange itself in the list of TOP 10 free software Arcade Games
and therefore its my own believe that Frogatto is a game that every GNU / Linux and FreeBSD desktop should have in Application -> Games GNOME menu.

Frogatto is rich of levels, enemies obstacles objects, places to visit (which puts it ahead of many of the linux arcade games which often miss enough game levels, has a too short game plots, or simply miss overall game diversity).

Frogatto linux freebsd game bombing airplaine

The game’s general look & feel is like a professional game and not just some tiny free software arcade, made by its authors for the sake to learn some programming, graphics or music creation.

Besides that Frogatto & Friends is multi-platform supporting all the major operating systems.
Game supports:
 

  • Windows
  • Mac
  • iPhone
  • Debian GNU / Linux
  • FreeBSD

The game source code is also available on Frogatto.com – The Game’s Official website

The game is available as a deb package in Debian and Ubuntu GNU / Linuxes so to install on those deb based distributions, simply use apt:

debian:~# apt-get install frogatto
...

The above command will install two packages frogatto (containing the game’s main executable binary) and frogatto-data containinng all the game textures, levels, graphics, music etc.

BTW the package saparation on a gamename and gamename-data in Debian (for all those who have not still noticed), can be seen on most of the games with a game data that takes more disk space.

After the game is installed the only way to start the game is to run it manually through pressing ALT+F2 in GNOME or running the progrtam through gnome-terminal with cmd:

debian:~$ frogatto

Here are few more Frogatto gameplay screenshots:

Frogatto different level screenshot

I’ve noticed Frogatto is also available as an RPM package for Fedora Linux, as well as has a FreeBSD port in the /usr/ports/games/frogatto and this makes it easy to install on most free software OSes in the wild.

While checking frogatto.com , I found an interesting link to a website offering free graphics (pictures), textures and sounds for free and open source games for all those who hold interest into the development of Free Software & Open Source Games make sure you check OpenGameArt.org

OpenGameArt.org looks like a great initiative and will definitely be highly beneficial to the development of more and better FSOS Games so I wish them God speed with this noble initiative.

Frogatto is very suitable for growing kids since it doesn’t contain no violence and every now and then the main game actor the Frogatto Frog leads few lines English dialogues with some of the characters found in the quest.
For none speaking English countries, the game can help the kids to learn some basic english words and thus can help develop kids intellect and knowledge
And oh yeah one more criticism towards the game is the Enlish structure, it seems people who wrote the plot can work this out in the time to come. Many of the English sentences during dialogues the frog leads with the cranks he met does not sound like a common and sometimes even correct english / phrases.

Besides those little game “defect”, the game is pretty awesome and worthy to kill some time and relax from a long stressy day.

Cleaning Packard Bell Hera GL laptop running Windows XP from Viruses and Spyware (Viruses / Spyware which can make CD drive and Wireless seem unworking)

Packard Bell Hera GL Fixing Broken RaLink Wireless

Yesterday, one (girl)friend of mine brought me one Packard Bell notebook, which had a 2 years old Windows installed on it.
As one can imagine Windows XP on it is full of Spyware and Viruses. Besides the software problems the notebook had some hardware problems with the CD / DVD which is not reading CD / DVDs at all.

Initially I thought, the CD unable to read problems are caused by the infected Windows, however even restarting the PC with a bootable Hirens BootCD and a Whoppix liveCD and trying to boot from it failed this convinced me its a CD / DVD combo drive hardware failure.

By the way, I’ve just recently found out about Nixory – Is a nice Free Software Open Source AntiSpyware tool for Firefox, IE and Chrome.

Nixory Windows XP Screenshot

I hope it will get a sharp development and soon, when some friend asks me to fix his stupid non free-Windows PC, I would not have to use a trial version of Malware Bytes but directly use only Nixory

Anyways after using Nixory, MalwareBytes and Avira and thoroughfully scanned the system in Safe Mode and found and deleted some 15 Spyware / Viruses and tampered a bit with the Wireless Driver settings all the notebook devices started working fine again.

The wireless had also one really odd problem on this Packard BellHera GL, even though the notebook wireless antenna was capable of detecting all the wireless networks it couldn’t properly connect to any of it but failed to get proper IP addresses.
Partially the unable to grab an IP via wireless router dhcp server got fixed by using the Wireless restart Button (located on the Notebook corpus).
However even after cleaning up the Virus and Spyware the Wireless Networks connectivity problems on this Packard Bell continued, until I changed also few settings in the Control PanelI never thought Viruses / Spyware infected can have some bad impact on Wireless Card and CD drive make them unsusable though they showed like working correctly in Windows Control Panel -> System ??

In the meantime I reinstalled the Wireless Driver for the notebook, the Wireless card on the notebook was showing up itself under the name of Ralink 802.11n Wireless Lan Card in Windows Device Manager

After re-installing the wireless driver I had to also change few settings for the Wireless Network Connection using the menus Properties -> Configure -> Extended; therein everywhere for each Value I make it be Enable and for Power Saving Mode , I’ve choose the Value option of CAM

After a system reboot, everything started working finally fine. One last thing to add is that before I fixed the Ralink wireless to work under Windows, I tried to use a Bootable Linux LiveCD but even there the wireless was failing to connect to the wireless networks (maybe this shit wireless device has some issues with its Linux drivers).

Free Software Songs and Videos Collection – (Anthem of Free Software) various interpretations

Friday, November 18th, 2011

Richard Stallman picture

I've gathered a collection of 15 Audio and Video songs dedicated to the Free Software / Open Source movement . All of the songs are based on the The Free Software Song Anthem written by Richard Mathew Stallman in the year 1991. The motive of the song is a Traditional Bulgarian song called Sadi Moma Bqla Loza – translated to bulgarian to something like Maid is Planting white Vines
The original Free Software Song symbolizes all free software and the Free Software Movement and GNU and is in the Bulgarian unique / specific folk rhythm of 7 / 8 beats .

Most of the songs which I post hereby could also be found and downloaded from GNU's official Free Software Song page
However some of the songs were only available from Youtube in the non-free format Flash Video (flv) . Hence, since the songs were dedicated to Free Software and apparently were being spread in a non-free format they either was missing any licensing or licensed under GFDL free music / art GNU like license.
To fix up this irragularity and add some freedom in terms of audio format of spreading, I've downloaded them and used ffmpeg2theora to convert the songs to the Free / Open Standard format Ogg Vorbis
I'm quite sure that many people, who use Ubuntu or Linux Mint are pretty much unfamiliar with the Free Software Songs existence, also many people most likely have never heard the Free Software Songs or even those who heard it have rarely heard more than 2 or 3 of the song variations.
Hereby, I'm sure many people who are lovers of Free Software will highly benefit and get inspired to continue in the Free Software by listening to these post shared little Free Software Song Collection .

The covers of the Original version publicly sang by Richard Stallman are in different musical genres, some of the song performances are in Folklore, played on Piano other covers are performed by musical bands in pop / punk en popular music styles, there are one person performances, cheerful christmas like soundings, 8 bit free software song, Metal free software variations etc. In the collection I've included also few other nice songs which are propaganda on free software, even though not a cover of the Free Software Song , I found them myself worthy to be included in the collection..:
