I am still trying to track down the actual UDP port it listens on but as
far as I can tell, netstat -nlp shows port 1029 open but doesn't list
which process has it open.  lsof doesn't show xfs using UDP, but both show
the unix socket in use by xfs.  The xfs man pages talk about TCP port
assignment and I can't find the source for the -udpPort 0 workaround I am
playing with.  That all said :) when xfs is started with -udpPort 0, udp
port 1029 stops listening. *shrug*

Nah, paranoid is having a listing that denies all traffic from the IANA
reserved blocks properly listed and/or bitmasked so no one can use the
reserved addresses (and not just the RFC 1918 ones either :) to spoof
pakcets at my firewalls :)  as well as the known trojan port list, a black
hole list for known bad addresses.... *grin*

And as a side note, yes IPChains is designed to stop packets from getting
at all the services that are running on a particular box.  That was why I
originally posted that everyone needs to be running some sort of firewall,
ie IPChains.  As far as the policy settings for IPChains, they should
reflect your general security policy.  If your model is "That which is not
explicitly denied is allowed" then the IPChains policy rules for your
firewall should be -P ACCEPT.  If you go with a "That which is not
explicitly permitted is denied" then use the -P REJECT or -P DENY for your
chain policies.  I did not mean to imply in my first post that the ports
listening in the netstat output were listening THROUGH the firewall, but
showed the need for a firewall to be put in place :)
