I use openssh3.5p1.

I put "VerifyReverseMapping no", but it did not work. I meant, the
sshd response still slow.

But, if I put dummy domain name in /etc/hosts :

   10.0.0.88 dummy

Then the sshd response is very quick.

So, what's VerifyReverseMapping does ? broken ? or has not implemented
yet .
