Also, if you are running daemons which use <B>identd</B> services to "authenticate" incoming connections and the identd services are not set up correctly, the initial login will be very slow and hang for some time. (this is almost the same as the DNS lookup problem).
I recommend putting a sniffer like <B>tcpdump</B> on the segment and watching what happens. This will isolate the problem quickly.

UUIDD(8) System Manager's Manual UUIDD(8)
NAME
uuidd - UUID generation daemon
SYNOPSIS
uuidd [-d] [-p pidfile] [-s socketpath] [-T timeout]
uuidd [-r|-t] [-n number] [-s socketpath]
uuidd -k
DESCRIPTION
The uuidd daemon is used by the UUID library to generate universally unique identifiers (UUIDs), especially time-based UUIDs, in a secure
and guaranteed-unique fashion, even in the face of large numbers of threads running on different CPUs trying to grab UUIDs.
OPTIONS
-d Run uuidd in debugging mode. This prevents uuidd from running as a daemon.
-k If currently a uuidd daemon is running, kill it.
-n number
When issuing a test request to a running uuidd, request a bulk response of number UUIDs.
-p pidfile
Specify the pathname where the pid file should be written. By default, the pid file is written to /var/run/uuidd/uuidd.pid.
-s socketpath
Specify the pathname used for the unix-domain socket used by uuidd. By default, the pathname used is /var/run/uuidd/request. This
is primarily for debugging purposes, since the pathname is hard-coded in the libuuid library.
-r Test uuidd by trying to connect to a running uuidd daemon and request it to return a random-based UUID.
-t Test uuidd by trying to connect to a running uuidd daemon and request it to return a time-based UUID.
-T timeout
Specify a timeout for uuidd. If specified, then uuidd will exit after timeout seconds of inactivity.
-q Turn on quiet flag.
AUTHOR
The uuidd daemon was written by Theodore Ts'o <tytso@mit.edu>.
AVAILABILITY
uuidd is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
