You may already know this but I thought I'd mention it anyway.  Ubuntu 
has /sbin/reboot.  There is a man page that documents the options to 
halt or turn off the machine instead of rebooting.  It's in the default 
path.

Reboot is what Gnome uses to execute a shutdown/reboot when requested. 
It works perfectly with SSH.

One other thing you might want to do.  For instances where the machine 
gets so unresponsive that even the command line won't work, I've 
configured a separate "reboot" login.  Instead of executing /bin/sh, it 
directly executes /sbin/reboot.

To do this, simply create a new account named, say, shutdown.  Then edit 
/etc/passwd, find the new entry for the shutdown account and replace 
"/bin/sh" or "/bin/bash" with "/sbin/reboot -f".

I use the "force" option because I've had machines get so wonky that 
shutdown(8) would not run or at least would not run in a reasonable 
length of time.  With -f, the machine simply flushes the disk caches and 
goes down.  Never had it fail.
