 server is accessible:

This is where it falls apart.  ted is the head node

[root at ted fs]# pwd
/etc/X11/fs
[root at ted fs]# grep share config
catalogue = /usr/share/X11/fonts/misc:unscaled,
    /usr/share/X11/fonts/75dpi:unscaled,
    /usr/share/X11/fonts/100dpi:unscaled,
    /usr/share/X11/fonts/Type1,
    /usr/share/X11/fonts/TTF,
    /usr/share/fonts/default/Type1,
    /share/apps/Mathematica7.0/SystemFiles/Fonts/Type1,
    /share/apps/Mathematica7.0/SystemFiles/Fonts/BDF,
    /share/apps/Mathematica7.0/SystemFiles/Fonts/AFM
[root at ted fs]# service xfs restart
Restarting xfs:
Shutting down xfs:                                         [  OK  ]
Starting xfs:                                              [  OK  ]
[root at ted fs]# netstat -alnp | grep 7100
unix  2      [ ACC ]     STREAM     LISTENING     10796483
6976/xfs            /tmp/.font-unix/fs7100
unix  3      [ ]         STREAM     CONNECTED     10796698
6976/xfs            /tmp/.font-unix/fs7100

Then from the Mac:

 xfsinfo -server ted:7100
xfsinfo:  unable to open server "ted:7100"
gc166-mad:~ mad$ xfsinfo -server ted.hetchem.brown.edu:7100
xfsinfo:  unable to open server "ted.hetchem.brown.edu:7100"

I  modified the iptables to allow tcp for input and forward on eth1; eth1 is
the connection from the head node to the outside.

This did not help.
