Binary package “xrsh” in ubuntu xenial

remote execution of XWindow programs

 Xrsh is designed to allow you to start an X client on a remote machine
 with the window displayed on the current server's $DISPLAY. It has
 many options that give you the ability to propagate environment
 variables (including DISPLAY) to the remote system and works with
 various types of X server access control including xauth and xhost.
 Xrlogin opens a local xterm window and runs rlogin (or optionally telnet) to
 connect to a remote machine.
