The accounts don't have to have the same name for this to work. I can connect
(as root) to other machines on my LAN:
[summer@numbat summer]$ ssh -l root gw
Last login: Sat Aug 17 14:27:26 2002 from numbat.computerdatasafe.com.au
[root@gw root]#
I actually have this set up as a function in ~/.bashrc:
[summer@numbat summer]$ grep -A4 root .bashrc
function root()
{
RH=$1
shift
[ -z "$RH" ] && RH=${HOSTNAME}
ssh -t -l root $RH $@
return $?
}
so that I can access the machine:
[summer@numbat summer]$ root gw w
12:08pm up 42 days, 1:03, 10 users, load average: 0.28, 0.11, 0.09

root pts/10 numbat.computerd 12:08pm 1.00s 0.04s 0.04s w
Connection to gw closed.
[summer@numbat summer]$ root gw

[root@gw root]#
The root command without operands logs in as root on my own machine.
