Subject: openssh-server: Bogus warning, "Authentication tried for XXX with correct key but not from a permitted host"

Date: Sun, 19 Dec 2010 21:14:22 -0800

Package: openssh-server
Version: 1:5.5p1-5+b1
Severity: normal

I'm getting this warning by mistake. If my authorized_keys file
contains:

    from="hostA" ssh-dss <hostA-key> <hostA-addr>
    from="hostB" ssh-dss <hostB-key> <hostB-addr>

I *always* get this warning when coming in from hostB. If I swap the
order, for example:

    from="hostB" ssh-dss <hostB-key> <hostB-addr>
    from="hostA" ssh-dss <hostA-key> <hostA-addr>

then I only get this warning when coming in from hostA.

I would expect that I could come in from either hostA *or* hostB
without this warning.

Sorry for the bad subject line in my last reply.  I really was talking 
about this bug, not the one I mentioned in my last subject line.

This seems to apply with only one key in authorized_keys, if someone
genuinely is attempting to ssh into my box from a non-permitted host.

Unless they really have got hold of my key ... which makes this log
message kind of scary.
