SSH: how to disable "hostname reverse checking"?

Hi there!

I've got a problem with some user. He works from strange VPN from home and SSH doesn't login him with the following error:
Feb 23 23:34:38 ibm305 sshd[16153]: reverse mapping checking getaddrinfo for XXXX failed - POSSIBLE BREAKIN ATTEMPT!

How can I disable this checking?

P.S.: I tried set "UseDNS" to "no". After that, he still can't login, but I didn't see any log records about his attempts...

Thanks in advance!

These are two different problems. The inability to login is a separate issue from the verbose logging (unless you have some wierd sshd config). Check out /var/log/secure for more details about failed login attempts.
