Hi Jacek, Then you have the latest one with the IPv6 recovery. So, obviously, the code can encounter issues which prevent it from downgrading to IPv4. Let me know when you encounter this again. It's pretty hard to find machines that have a misconfigured IPv6 stack. Maybe Karl can come up with one :-) Andy On Fri, 4 Sep 2015, Jacek Becla wrote: > Andy, > > They took down the openstack cluster I've been using so I can't check. > Let's revisit when it is up again. > > I used xrootd tagged as 2015_7 (Fritz, how do we map it to the version > that Andy is familiar with?) > > Jacek > > > > On 09/03/2015 12:43 PM, Andrew Hanushevsky wrote: >> Hi Jacek, >> >> Ah, the problem is that NCSA did not do a complete IPv6 setup.
