Linux Reality Episode 37 - SSH
Extra Notes

Standard SSH command: 
ssh user@hostname

examples: 
ssh workstation (using same user name) 
ssh joe@workstation (using different user name) 
ssh joe@192.168.1.50 (using ip address)
ssh joe@example.com (using domain name if server is off-site or over
the internet)

if using a nonstandard port, add "-p <port>" switch, e.g. 
ssh -p 11000 joe@workstation

Standard SCP command: 
scp localfile.txt joe@workstation:/home/joe/localfile.txt or 
scp localfile.txt joe@workstation:~/localfile.txt

can also do the reverse to pull a file down from a server: 
scp joe@workstation:~/localfile.txt localfile.txt

if using a nonstandard port, add "-P <port>" switch, e.g. 
scp -P 11000 localfile.txt joe@workstation:~/localfile.txt

Standard ssh-keygen command: 
ssh-keygen -t dsa or ssh-keygen -t rsa

When prompted for a password during key creation, enter none (press
'enter' key) so you can use password-less key

Copy your public key to server.  One way is with scp:

scp ~/.ssh/id_rsa.pub joe@workstation:~/id_rsa.pub

Once copied, ssh back into the machine and copy the public key into
the ~/.ssh/authorized_keys file on the server:

ssh joe@workstation 
cat id_rsa.pub >> ~/.ssh/authorized_keys

Dynamic Port Forwarding to create a SOCKS web proxy: 
ssh joe@workstation -D 8080

Then, change your proxy settings in Firefox to "localhost" under
"SOCKS host" and put 8080 as the port
