CentOS - May 2010 - ssh slow

Hi

How I can configure sshd_config to improve the ssh faster?

It is slow to prompt the login

Thank you

That usually indicates a DNS problem.  sshd tries to do a reverse DNS 
resolution to lookup the connecting client.

badly configured reverse DNS on the client hosts is the most common 
cause of this.  try ...

    UseDNS no

Fix your DNS setup and/or configure it to "UseDNS no".
Such slowdowns happen because sshd tries to get a reverse DNS lookup of your IP
address.

It can be a big PITA when you try to login into a server to fix a broken DNS and
the login times out because it tries to get a that PTR record back......


Just remember the mantra: "most weird network problems are related to DNS
problems....."
