Set Remote X Server Display
This section shows one how to set the "X Display" prior to starting up your web browser (i.e. firefox) to connect to the "NST WUI" for running an X Application. Case 1: Connect to a probe's "NST WUI" and run an X Application on a specific X Server. The script below is an example on how to do this.
#! /bin/bash
#
PROBE_IP_ADDR="172.31.1.190";
REMOTE_IP_ADDR="172.31.1.150";
#
/usr/bin/xhost +"${PROBE_IP_ADDR}";
#
/usr/bin/firefox https://${PROBE_IP_ADDR}?xdisp=${REMOTE_IP_ADDR}${DISPLAY}
