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?

Thanks!

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

Value no for verifyreversemapping did the trick!

Thanks to lynxman and upvoting for pointing me to the solution
