Well, for better or worse my ssh keys are in my home directory. My home directory physically resides on a Netapp and it is remote mounted to several hundred systems. You're right, it's a drag when the Netapp is having a bad day.

But that's not what prompts my guess. Trouble with ssh keys won't slow down telnet. DNS or networking issues won't slow down only telnet/ssh but leave ftp running ok. So I figure that something else is afoot.

A Solaris system with slow telnet and ssh but fast ftp... I see that all the time. Almost always the Solaris box is stuck checking quotas on some obscure file system that is NFS mounted but has a stale file handle. But my guess does have trouble too. Quotas are checked after the user is authenticated but before a shell prompt appears. Still a quick "df -k" on the destination system would be the first thing I would check.

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.
