A few tricks to make ssh use easier..

Keys

So you can log in without giving a password. Generate key on machine to be connected from using ssh-keygen then copy it to the authorized_keys file on the machine to be accessed.
[code]
ssh-keygen – t rsa
scp ~/.ssh/id_rsa.pub remotemachine:
ssh remotemachine
cat id_rsa.pub ~/.ssh/authorized_keys
rm id_rsa.pub
[/code]

Config file

So I can loggin using a simple name rather than otheruser@long.complicated.host.name. This is the contents of my laptops .ssh/config file:
[code]
Host name1
HostName realname.com
User remoteuser
ProxyCommand /usr/local/bin/connect -S socks.ncl.ac.uk %h %p
Host name2
HostName realname.com
User remoteuser
[/code]
This gives me 2 methods of accessing the same server. The first (ssh phuquockites) works on the uni network which requires socks proxying. The second (ssh soulflyer) works from home.
