Hello,
I just finished up an upgrade to LCG-2_4_0 and everything seemed to be
working fine until I noticed that the BDII server is no longer reachable
from the worker nodes. The peculiar thing was that the BDII was reachable
from everywhere else. I came to the conclusion was that there is a problem
with having our workers behind a NAT box and the new iptables rules.
The reason I believe this is a problem is due to the fact that the worker
nodes can see all other ports just fine except for 2170. I can even query
the ldap on 2171-3. Does anyone have a suggestion on what I should do to
get this to work?
From the worker node's perspective scanning 2170-2173...
(The 1 port scanned but not shown below is in state: closed)
Port State Service
2171/tcp open unknown
2172/tcp open unknown
2173/tcp open unknown
Nmap run completed -- 1 IP address (1 host up) scanned in 1 second

Starting nmap V. 3.00 ( www.insecure.org/nmap/ )
Interesting ports on lcg-bdii

Thanks,
