Logging in, using a PC
The following information should allow you to log in to our server, "deva", using your CCB account.
We recommend using the NX remote desktop to access deva, particularly if you are new to using the command line interface. A connection via NX to the CCB server will create a virtual desktop - allowing you to run x-windows-based graphical tools as well as command-line tools. Instructions on how to set this up are below.
If you are familiar with using a command line interface you can also access the servers via a terminal.
NX is a remote desktop program which lets you to connect to a remote server and run graphical applications remotely on that server. Your local machine acts like a terminal on the remote server. NX connections are secure as they use SSH encryption and authentication.
