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.
