Red Hat Bugzilla – Bug 699421
ssh requests ipv6 addresses even with ipv6 disabled
Last modified: 2011-04-30 23:23:53 EDT
Description of problem:
I have a DSL router that fails to respond to AAAA records properly:
3.853196 192.168.100.67 -> 192.168.100.1 DNS Standard query A pkgs.fedoraproject.org
3.853344 192.168.100.67 -> 192.168.100.1 DNS Standard query AAAA pkgs.fedoraproject.org
3.897350 192.168.100.1 -> 192.168.100.67 DNS Standard query response A 18.104.22.168
3.903481 192.168.100.1 -> 192.168.100.67 DNS Standard query response
This results in:
ssh: Could not resolve hostname pkgs.fedoraproject.org: Name or service not known
This is the case even with ipv6 completely disabled. Work around is to run "ssh -4 hostname". Other programs like firefox and thunderbird work with ipv6 disabled.

I see this has been fixed in rawhide, will we see it fixed in F15 soon? Thanks!
please test it and report. I do not put it into f15 before positive feedback.
If you have no way how to test it in rawhide I prepare testing package for you.
Works perfectly. Thanks.
