Full Discussion: Solaris 9 - SSH 40 Second Delay

Solaris 9 - SSH 40 Second Delay
I'm having an issue with SSH on a server that hasn't had any configuration changes made on it in a long time. I SSH to the server and it hangs at "debug1: SSH2_MSG_KEXINIT sent" for exactly 40 seconds then connects fine after that pause. Everything I have found points to DNS, but I use host files for DNS and like I said it has worked for years and there hasn't been any changes, so I'm kind of at a loss... If anyone has any ideas or something I could try it would be very helpful... Thanks!

ssh-keysign

SSH-KEYSIGN(8)						    BSD System Manager's Manual 					    SSH-KEYSIGN(8)

NAME

     ssh-keysign -- ssh helper program for hostbased authentication

SYNOPSIS

     ssh-keysign

DESCRIPTION

     ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during hostbased authentication with
     SSH protocol version 2.

     ssh-keysign is disabled by default and can only be enabled in the the global client configuration file /etc/ssh/ssh_config by setting
     HostbasedAuthentication to ``yes''.

     ssh-keysign is not intended to be invoked by the user, but from ssh(1).  See ssh(1) and sshd(8) for more information about hostbased authen-
     tication.

FILES

     /etc/ssh/ssh_config
	     Controls whether ssh-keysign is enabled.

     /etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_rsa_key
	     These files contain the private parts of the host keys used to generate the digital signature.  They should be owned by root, read-
	     able only by root, and not accessible to others.  Since they are readable only by root, ssh-keysign must be set-uid root if hostbased
	     authentication is used.

SEE ALSO

     ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)

AUTHORS

     Markus Friedl <markus@openbsd.org>

HISTORY

     ssh-keysign first appeared in OpenBSD 3.2.
