Need a linux terminal for practising linux online.


I am using windows XP. But i want to practice the linux commands online, as everything in my office is RHEL-4 .
Iam rightnow, practising through, but its time seems to be expired. Any other sites, which provides online terminal ?

I'm afraid I can't help directly, but what is your overriding reason for not using a solution on your own hardware. I'm thinking Live CD/USB, Virtualbox, dual boot or even WUBI?

I recently posted on my blog here about DIY UNIX fundamentals courses. Suggesting something like would never have occured to me.

Do you have VPN access to your office? If so you should be able to run PuTTY on your XP laptop to access the RHEL4 systems in the office. (Although you might need to have Security folks in your office open up access to specific systems depending on how they do VPN.)

You can also setup your laptop to be a dual-boot machine with XP in primary partition and Linux in secondary. There is (or at least was) a good write up on how to do this with Gparted. You'd want to load RHEL4 (if authorized) or CentOS 4 (which has no restrictions) as it is binarily compatible with RHEL4.

Alternatively if you just want to do Linux style commmands you could install Cygwin on your XP laptop - it runs Linux under XP.

Finally - not having used before I can't say how reliable it is but I will make these observations from looking at it:
1) After you register they send you an email from "" to complete the registration. It appears that if you don't click on the link in that email they expire your account in about 14 days. If you do click on it they don't expire it.
2) The OS they are providing says "Fedora 2" which is really old. It has a 2.6 kernel so I don't think it is really that old or at least they are adding stuff to it but it might not be exactly the same as your RHEL4 (/etc/redhat-release says it's RHEL 3 - go figure). also provides free shell accounts but those are on BSD not Linux. Depending on what you want to do it may be close enough.
The looks interesting as they're actually giving you a virtual machine with root so don't have the restrictions you'd find on

There is a java virtual machine that should work on almost all systems. Takes me forever to find it. and you can run linux from a browser.

There may be other NX based systems that you could access too. I forget where they might be.

Plenty of small OS's that can run on qemu. Some are fully setup and easy to run from a flash drive.

Another way may be to use a live cd or floppy to practice. Boot computer to the OS and learn.

Another way is to use a dos based clone of linux/unix. MKT tools used to offer a neat way to run linux commands in dos.

Might install services for unix as it has almost all of the common commands.

Might move up to a live usb flash install and boot to it. See

There is also a cd that has cygwin from I think Indiana University. Put the cd in and you can run linux command line stuff.

As you are trying to learn I'd suggest you do not attempt to access your RH systems until you are fully trained.

Click on test-drive to check if it might offer what you are looking for:
It's rather an environment than a terminal (i only tested once if it works at all, not for general usage)
I would go for cygwin.
