What is doing the "reverse lookup"? And can I just turn that off? It
doesn't seem to make much sense to me that I add complexity in the
form of a dns server that does little more than convert the ip
address brom binary form to printable characters. I'd rather just
skip the reverse lookup altogether.
Am I missing some fundamental philosophy here? What's the point of
reverse look ups in such cases?
Sshd does this so it can apply the tcp-wrappers rules from
/etc/hosts.allow and /etc/hosts.deny.
Set "UseDNS no" option in /etc/ssh/sshd_config to disable this.
Since /etc/hosts.allow and /etc/hosts.deny contain only comments, this
seems like a good idea.
I now have "UseDNS no".... working great. :-) That solved 50% of my
current problem set.... sounds like there is a similar solution for my
smtp server...
Thanks...
