Description Per Steinar Iversen 2001-10-15 07:58:26 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.4) Gecko/20010913

Description of problem:
openssh-2.9p2-8.7 does not allow access over IPv6 when there is a
tcp_wrapper type access control in /etc/hosts.allow based on domain.

This will work:

sshd: ALL
sshdfwd-X11: ALL

This fails:

sshd: .hio.no
sshdfwd-X11: .hio.no

The following is logged in this case:

refused connect from 0.0.0.0

Both the server and client have proper AAAA records and corresponding
entries in ip6.int


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Upgrade to openssh-2.9p2-8.7  This adds IPv6 support also to openssh.
2. If anything but ALL access is defined in /etc/hosts.allow access fails.
3.

Actual Results:  Access is denied.

Expected Results:  Access allowed.

Additional info:

This problem is probably because the part of openssh that reads
/etc/hosts.allow does not understand IPv6, AAAA records etc.

You need to rebuild openssh with updated tcp_wrappers (they were present only from RHL72 onwards) if you want
IPv6 connections to work.

Closing as fixed in Raw Hide.
