I have installed the latest openssh 4.5p1-r2 package on an AIX 5.3 server and the from="host" option in .ssh/authorized_keys no longer works properly.
The debug meesages from sshd show that it's comparing the IP rather than the hostname to the authorized_keys entry.
debug3: mm_send_debug: Sending debug: Your host '10.6.127.55' is not permitted to use this key for login.
from="hostxyz" ssh-dss AAAAB3NzaC1.....
The only work-around I have found so far is to use the actual IP in the from "" field
like the example below:
from="10.6.127.55" ssh-dss AAAAB3NzaC1.....
I have not seen this bug in previous releases of openssh.
