Thanks for the reply. Unfortunately however anything that requires interaction won't work inside the process running on the local machine.

The only other solution I have is for the remote process to write a file into a directory mounted from the local machine on the remote one. The local process can then check for its existence and remove it afterwards. This isn't ideal since theoretically anyone with write access to that directory can create this file but it might have to do.

rwho

RWHO(1) 						    BSD General Commands Manual 						   RWHO(1)

NAME

     rwho -- who is logged in on local machines

SYNOPSIS

     rwho [-a]

DESCRIPTION

     The rwho command produces output similar to who, but for all machines on the local network.  If no report has been received from a machine
     for 11 minutes then rwho assumes the machine is down, and does not report users last known to be logged into that machine.

     If a users hasn't typed to the system for a minute or more, then rwho reports this idle time.  If a user hasn't typed to the system for an
     hour or more, then the user will be omitted from the output of rwho unless the -a flag is given.

FILES

     /var/spool/rwho/whod.*   information about other machines

SEE ALSO

     finger(1), rup(1), ruptime(1), rusers(1), who(1), rwhod(8)

HISTORY

     The rwho command appeared in 4.3BSD.

BUGS

     This is unwieldy when the number of machines on the local net is large.
