Nasty PTR record from ssh and segfault in glibc
Last modified: 2007-11-30 17:11:31 EST
Description of problem:
Openssh refuses incoming connections and returns errors in the logs:
Nasty PTR record "perihelion.int.jonmasters.org" is set up for 192.168.1.3, ignoring
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. ssh into box
2. it fails
Cannot connect via ssh
Can connect to box
Tomas says it might be a problem glibc with a change in sematics to getaddrinfo.
Setting "UseDNS no" in sshd_config works around the problem temporarily.

Here is the testcase.
So this is definitely a bug in glibc. At least it shouldn't segfault and I think
the semantics shouldn't change either.
