It can be used to make terminal connections to the undergraduate systems or to copy files between your laptop/home system and the undergraduate systems using 'pscp' (one of the utilities that comes with PuTTY). PuTTY: A free implementation of Telnet and SSH for Windows and Unix platforms which works quite well with our systems.Select an SSH client depending on which operating system you're running. On the research network you can connect to innisfree.cs.ualberta.ca. In general we suggest students connect to ohaton.cs.ualberta.ca, as it is on extended hours support, and will have the greatest possible availability of all machines the undergraduates can access. This is now the preferred method for getting your data to and from your Computing Science account. Scp is a replacement for rcp, and allows your to copy files across a network. Unlike telnet and rsh, SSH encrypts your password and all traffic when connected, so you are less vulnerable to attacks by unscrupulous users that want to get your password. You need to use SSH to remotely access the undergraduate machines and resources.
SSH (Secure Shell) is a program that allows you to access a computer remotely from another computer.
