Thanks Owen, hope the home disaster isn't too disasterous.
Looks like we ran afoul of the change in the ports are dcache was
using for globus. Pre-upgrade we were using the 20000-25000 range but
that was changed to 50000-52000 with the upgrade. As it's easier to
edit and restart iptables then dcache I thought I'd go with the flow
and open up those ports, shout if you think that's a bad plan.
Things are going alright now, Greig are there any other firewall
tweaks you advise?
