restart ssh in linux

If you're trying to start the server daemon, then try:
/etc/rc.d/init.d/sshd restart

If you're trying to run the ssh client from your linux box, then just ssh xxx.xxx.xxx.xxx

all running processes
ps -ef
ps -ef | grep konqueror (ssh or something else)
ps -ef | grep user 'name'

like the guy said

just type ssh

To see all running processes I usually type:
ps -aux
This shows everything as well as %mem and %cpu.

As for ssh service:
To restart the daemon (works even if you're connected remotely): /etc/init.d/sshd restart

For connecting:
ssh @

Hope this helps.
