HEllo my friends...

My fedora 7 server has become very slow in the login phase from ssh or telnet. I just use ip to connect (no dns needs) and when I log locally it's fast as usual. If I ping or traceroute the server the connection is fast as usual and I get no dropped packets...

Any hints to resolve/debug?

Could it be related to DNS?

Try adding this option to your /etc/ssh/sshd_config

UseDNS no

And then restart your ssh daemon, this should sort it out

Also tried: GSSAPIAuthentication no /etc/ssh/ssh_config No luck – Pitto Jan 18 '11 at 10:54

Value no for verifyreversemapping did the trick!

Thanks to lynxman and upvoting for pointing me to the solution
