X Font Server -- Client Request (Inbound)

Category: REMOTE-ACCESS

Application: X Font Server

The X font server (xfs) provides a standard mechanism for an X server to communicate with a font renderer, frequently one running on a remote machine.

The use of server-side fonts is currently considered deprecated in favour of client-side fonts.

This SonicWALL signature identifies legitimate X Font Server traffic.
