failing ssh login attempts

[Adam Weremczuk <adamw@matrixscience.com>]

Hi all,

I recently performed a series of distro upgrades starting from 7.1 
landing at 9.2.

I have a script running on another 7.1 machine which was connecting fine 
to 7.1 but now it fails after reading authorized_keys file as below:

11437 read(4, "from=\"*.example.com\" ssh-rsa AAAAXXXXXXXXXX"..., 4096) 
= 4096
11437 getpid()                          = 11437
11437 socket(AF_UNIX, SOCK_DGRAM|SOCK_CLOEXEC, 0) = 8
11437 connect(8, {sa_family=AF_UNIX, sun_path="/dev/log"}, 110) = 0
11437 sendto(8, "<38>Jan 11 16:21:32 sshd[11437]: Authentication tried 
for userx with correct key but not from a permitted host 
(host=192.168.XXX.XXX, ip=192.168.XXX.XXX)"..., 147, MSG_NOSIGNAL, NULL, 
0) = 147
11437 close(8)

So I've tried, -vvv from the source, DEBUG3 on the destination and the 
strace above but can't see anything (such as reversed DNS lookup) apart 
from this single error message.

Connection is established fine when I replace *.example.com with an IP 
address but that's not very scalable.

Can somebody possibly put me in the right direction?
