Assuming that server A is reachable from server B and vice
versa:
We can execute the command remotely using rsh and by using
admin credentials of server B as below from server A:
rsh <server B IP> -l <admin login name> -n "ps -eaf | grep -
i <service_name>"
For eg; to find httpd service we can use the following
command assuming server B IP is 10.0.0.10 and root has
admin previledges:
rsh 10.0.0.10 -l root -n "ps -eaf | grep -i httpd"

Answer / shh
rsh command
executes command on the specified hostname. To do so, it
must connect to a rshd service (or daemon) on the hostname
machine
rsh [username@]hostname [-DNn] [-l username] command
-D
enables socket debugging on the TCP sockets used for
communication with the remote host. This option also
displays the locuser and remuser being sent to rshd
-l username
specifies the remote user name to be used when executing
the command. This can also be specified by including
username@hostname on the command line
-N
does not generate a separate standard error stream. All
output is sent to standard output. This is useful when you
are running an interactive command
-n
redirects input from the special device /dev/nul.
