who@ - print list of active users on a host

who@  connects  to  TCP  port  11  (Systat)  on  host and prints any data it receives.  It removes CR and
       converts unprintable characters to a visible format.

       If host is not supplied, who@ connects to the local host.

       Some computers respond to port 11 with a list of active users.  For example, they may be running

            tcpserver 0 11 who &

       who@ - print list of active users on a host

cat(1), delcr(1), tcpclient(1), tcpserver(1)
