Add the hitlar mode alias to your .bashrc. bash-3.2$ echo "alias hitlar='ls -Fhitlar'" >> ~/.bashrc bash-3.2$ hitlar bash-3.2$ hitlar filename

host B (you) redirects a modem port (62220) to his local ssh. host A is a remote machine (the ones that issues the ssh cmd). once connected port 5497 is in listening mode on host B. host B just do a ssh 127.0.0.1 -p 5497 -l user and reaches the remote host'ssh. This can be used also for vnc and so on.
