You are blocking any incoming DNS packets by blocking udp. I believe sshd tries to lookup the hostname of the ipaddress, it times out in few seconds, this causes the lag. This can also happen if your /etc/resolv.conf is pointing to unresponsive servers. Following are the following fixes. -> make "UseDNS no" in sshd_config -> allow DNS from iptables AND verify /etc/resolv.conf HTH Arun On Thu, 2006-05-25 at 00:37 -0700, atomi wrote: > I've got a pretty bare bones system.
