RH 5.2 xfs listens on UNIX port 7100 AND tcp port 7100 by default. It also accepts the -port argument to change this. RH 6 doc says the xfs in RH 6 will listen on tcp 7100 by default. It does not. It ONLY listens on UNIX port -1 !!!! (information confirmed by netstat -at and netstat -ax, the former revealing nothing relating to xfs even when xfs is plainly running, the latter revealing a UNIX protocol port at: /tmp/.font-unix/fs-1) Neither does it accept the -port argument (well, it accepts it, but it ignores it) Instructions on page 4 Installation guide suggest putting "Fontpath "tcp/localhost:7100" in XF86Config. This does not work (for the above reasons). Only "Fontpath "unix/:-1" works.
*** Bug 2514 has been marked as a duplicate of this bug. *** In section 1.3.0.1 (Enhanced font support) of the installation guide (I am looking at the electronic version from the rhl-install-guide-en-6.0-2 rpm) you give instructions for using the new font server instead of a conventional fontpath. Those direction say to use "tcp/localhost:7100" in the fontpath. However, the version of xfs in XFree86-xfs-3.3.3.1-49 has intentionally had TCP functionality removed (XFree86-3.3.3.1-xfsredhat.patch modification of file XFree86-3.3.3.1/xc/programs/xfs/os/connection.c). The correct instruction would be to use "unix/:-1" in the fontpath.
