Re: [cobalt-users] slow telnet response...

[Frank Smith <fsmith@xxxxxxxxxxx>]

It means your DNS is broken.  The server does a reverse lookup on the IP
address connecting to it so it can log the hostname.  If it can't resolve
it before it times out (about a minute),  it gives up, logs the IP, and
continues on normally.
   Fix it so the server can resolve the client IP and your delay will
disappear.
