Secure Shell is a secure replacement for insecure programs like telnet and rsh. It is the only supported method of accessing systems at the RCF. Ssh clients are available for most popular platforms in both free and non-free forms.

A list of Ssh clients is given in the Ssh FAQ. For RCF Users, a Web browser based (Java) Ssh client is available from the RCF (Note that you need an RCF account to access the Ssh client.)
