This is where it falls apart. ted is the head node
[root@ted fs]# pwd
/etc/X11/fs
[root@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@ted fs]# service xfs restart
Restarting xfs:
Shutting down xfs: [ OK ]
Starting xfs: [ OK ]
[root@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.
