Hi Jacek,
Ah, the problem is that NCSA did not do a complete IPv6 setup. Buy
default, xrootd starts up using IPv6 if there is a usable IPv6 interface.
However, that won't work if the IPv6 setup is not complete relative to
DNS. You can force xroot to start it IPv4 mode by adding the "-I v4"
command line option. We've seen this before and we have making patches to
get around this problem when we encounter it. So, I am a bit suprised that
there is yet another way of this not working. What version of xroot is
being run there?
