Comment 3 for bug 458223

I have run into this recently on one of the Ubuntu servers. However, this does not seem to be related
to Ubuntu or Debian at all.

The problem is that upstream DNS is running:

$ dig +short chaos txt version.bind.
"PowerDNS Recursor 3.1.4 $Id: pdns_recursor.cc 917 2006-11-07 12:23:51Z ahu $"

PowerDNS 3.1.4 is known not to support multi-line TXT entries.
For details see my collection of links here:

The results returned are:

; <<>> DiG 9.5.1-P2.1 <<>> in txt _aiccu.sixxs.net

And consequently, "aiccu brokers" returns only "SixXS|".

While this is not per se a bug in AICCU, I think we can make it a bit more careful
about what is returned from DNS and to ignore all records shorter than 4 "columns".

Attached patch does this and fixes the debian package issue (I have re-generated
the package and it installs and configures fine).

I didn't check whether it compiles on Windows.
