bash completion no longer works for ssh known_hosts

Hm, I can not reproduce this.

Can you please provide the output of the following commands:

complete -p ssh

dpkg -s bash-completion | egrep Status\|Version

Thanks!

achiang@soy:~$ complete -p ssh
complete -F _ssh ssh

achiang@soy:~$ dpkg -s bash-completion | egrep Status\|Version
Status: install ok installed
Version: 20060301-3ubuntu1

Hm, do you by any chance have the UserKnownHostsFile option set in either /etc/ssh/ssh_config or ~/.ssh/config ?

Yes, I do have that option set, but it's not set for that particular host.

Host proxies
        UserKnownHostsFile /dev/null
        StrictHostKeyChecking no

Host *
        TCPKeepAlive no
        ServerAliveCountMax 3
        ServerAliveInterval 10
        ControlMaster no
        ControlPath ~/.ssh/%r-%h-%p-mux
        HashKnownHosts no

Note that for the host I'm talking about above (chizang.net), I don't even have an entry at all:

achiang@soy:~$ grep chizang .ssh/config
achiang@soy:~$

OK, that explains it then. bash_completion just greps the config for UserKnownHostsFile and uses that exclusively if found.

In your case that's obviously wrong. So I'll change it to use the standard files in addition to those found via UserKnownHostsFile.

That should fix it the problem.

This bug was fixed in the package bash-completion - 20060301-3ubuntu2

Just a followup ACK that this fixes my problem.

Thanks!
