I have a quick question that I can't seem to find an answer to via Google 
so far.

I've had a few people complain that when they telnet/ssh/ftp/web to our 
server, it's slow... I've traced the problem to them having no reverse on 
their IPs.

So basically their connection kinda hangs while the system waits to 
timeout on looking up their IP's reverse.

>From what I can tell, I should be able to just set "options timeout:n" and 
"options attempts:n" in resolv.conf.. BUT it seems FBSD's install doesn't 
allow you to do this.

Does anyone know a workaround to this? I thought maybe of changing it 
directly in resolv.h but then I'd have to rebuild world I think..? Is 
there perhaps a sysctl solution?

Thank you so much for your time.
