External Access

You can connect remotely (from home etc.) to the CS student server using SSH/SCP. SSH gives you the ability to run commands (like compilers etc.) on the server, whilst SCP is for file transfer. SSH and SCP are secure alternatives to telnet and FTP.

SSH/SCP access to the CS student server is unrestricted, and doesn't require any application or registration to use - you can use it immediately, from anywhere.

First, you'll need an SSH/SCP client for your home computer. There are many SSH/SCP clients freely available for Mac, Linux/Unix, and Windows - some of the more popular ones are listed below:

• OpenSSH (Linux/Unix incl. Mac OS X) - http://www.openssh.org (note that most Unix systems have this installed by default)
• PuTTY (Windows) - http://www.chiark.greenend.org.uk/~sgtatham/putty/

Then, you'll need to know which machine to connect to. Here is the hostname and IP address for the CS student server:

• uss.cs.adelaide.edu.au (129.127.232.1)

NOTE: The IP address for the student server has recently changed, and may change again in the future. It's better to use the fully qualified hostname rather than IP address, as the machine's name is less likely to change compared to its IP address. The fully qualified hostname is uss.cs.adelaide.edu.au

Now, all you need to do is run your SSH/SCP program, and connect to one of these servers - if you're unsure how to use your SSH/SCP client, read the documentation! (the docs for the clients mentioned above are generally pretty good) If you're still having trouble connecting, go see a systems person.

If you're *really* keen, or masochistic, you can actually run an Xsession and thus use GUI applications over SSH! Be aware, though, that it will be horrendously slow over a modem. Ideally, you'll want a Broadband ((A)DSL or Cable) Internet connection.
