Secure SHell (ssh)

ssh and scp are enhanced replacements for rsh, rlogin and rcp. They use encryption to make sure that no-one can monitor your network traffic.

ssh also has "port forwarding" which allows you to run other network connections (like X sessions (eg. xterm), email, etc.) through an encrypted "pipe".

Using ssh-agent allows you to manage ssh passphrases so that you only have to enter them once per session.

CSG runs the ssh daemon (which allows ssh connections) on all its servers and lab machines. Similarly ssh and scp are installed on all servers and lab machines.

CSG currently runs ssh version 1.2.26. We don't run version 2 of ssh has restrictive licensing conditions (ie. you have to pay to use it.)

You can get ssh for Unix (and Linux) at:

: ftp://ftp.auscert.org.au/pub/coast/mirrors/ftp.cs.hut.fi/ssh

You'll have to build it and install it yourself.

There are "freeware" ssh clients (eg. PuTTY) available for Windows.

To find PuTTY use Yahoo or Altavista and search for "ssh" or "PuTTY".
