Running lsf with FastX

A default installation of FastX does not allow incoming connection from non localhost systems.This provides maximum security of the fastx session.
Certain applications however (most notably lsf) require systems to listen for incoming connections in order to function properly.  System administrators must enable FastX to listen on TCP connections for this to work.

Enabling TCP connections

  1. Log in to the web interface as an admin
  2. Click on the System Configuration icon
  3. Click on Profiles
  4. Edit the Default Profile
  5. Set Enable X11 TCP Connections  to ON
  6. Save the profile
  7. Changes take effect when launching new sessions

Manual Configuration

This setting can also be configured manually by editing the “listenTCP” option in

/usr/lib/fastx2/config/session.json
