I think the error message should reflect that. To reproduce, run /usr/sbin/sshd -ddd -p 23 -oHostKeyAlgorithms=ecdsa-sha2-nistp256 Connect to let ssh remember the key, then run /usr/sbin/sshd -ddd -p 23 -oHostKeyAlgorithms=rsa-sha2-256 Connect again and observe the error -- You are receiving this mail because: You are watching the assignee of the bug.

In the changelog, there is an entry: 20001129 - (djm) Back out all the serverloop.c hacks. sshd will now hang again if there are background children with open fds. Does this mean that this is regarded as expected (and correct) behavior, that should not change in the future, or does it mean that this behavior is a known problem that someone will eventually fix? --Adam -- Adam McKenna

For systems where the local hostname is obtained as a short name without domain, there should be a ssh_config option "DefaultDomain" as in ssh-3.x from ssh.com. For the server, there might be a corresponding option in order to strip the domain name from the remote client name (if it matches the server's DefaultDomain) for use in auth_rhost2, since netgroups usually contain short
