I solved it: ctwm by default runs m4 on .ctwmrc. It defines
several macros, among them HOSTNAME, CLIENTHOSTNAME and SERVERHOST.
To get the values of these a nameservice lookup is done. With
/etc/host.conf saying "hosts\nbind" and the right /etc/hosts
entries for my machine the ns lookups no longer ask a remote ns.

It's also very cool for getting your menus set up correctly.  Instead
of having to adjust every single menu entry for a machine (say) when
you switch from telnet to ssh, you can just change one macro, and
reload the file.  Magic!

1. Using IPFilter to NAT Locally-Generated Traffic


I am looking for a NAT solution for Solaris 8 that is equivalent to
what the OUTPUT section of iptables provides for Linux.  My goal is to
trick some network monitoring applications on a Solaris server into
thinking that they have local access NATed devices that sit on provate
networks.  To do this, I need to be able to NAT the destination
address on packets that this application generates from the true
private address to the routable NAT address before it leaves the
server itself.

Everything I have read has pointed to IPFilter as the NAT solution of
choice for Solaris but I do not see how I can create the traffic flow
I am looking for.  If IPFilter can do this for me, how do I configure
it properly?
