Hi Josh,

It says that all the nodes are free. I forgot to add that I don't think it's an issue with a firewall.

-bash-3.1# pbsnodes -a
boba1.sinrg.local
      state = free
      np = 2
      ntype = cluster
      status = opsys=linux,uname=Linux boba1 2.6.18-53.el5 #1 SMP Mon Nov 12 02:22:48 EST 2007
