SSH: how to disable "hostname reverse checking"?
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: 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!
