Do you want to know what processes you have on your server?

Do you want to add an extra SSH user:
Type into console useradd username
Make a password for the user by typing in: passwd username

Do you want to reboot the server with SSH/Shell:
Type in /sbin/reboot [-n] [-w] [-d] [-f] [-i]

-n = Don't sync before reboot or halt.
-w = Don't actually reboot or halt but only write the wtmp record (in the /var/log/wtmp file).
-d = Don't write the wtmp record. The -n flag implies -d.
-f = Force halt or reboot, don't call shutdown(8).
-i = Shut down all network interfaces just before halt or reboot.
-h = Put all harddrives on the system in standby mode just before halt or poweroff.
-p = When halting the system, do a poweroff. This is the default when halt is called as poweroff.
