	Well, the patch tape from Apollo seems to have solved our problems
with the routing problems.  I strongly suggest that you all get this patch
if you run DOMAIN/IX and TCP/IP.  I also found that a number of our nodes
had some problems with their software.  Here are some of the changed that
I made that helped out TCP/IP:

1.	Check your /sys/tcp/hostmap/local.txt file(s).  Your should be
        especially careful with GATEWAY nodes.  Do this:

	NET : 98.0.0.0 : APOLLO-RING :
	NET : 192.12.206.0 : IU-NET :
	GATEWAY : 98.0.0.1, 192.12.206.194 : DAPHNE.CS.INDIANA.EDU : DN560 : \
	 DOMAIN : IP/GW, GW/DUMB :
	HOST : 192.12.206.1, 98.0.0.1 : GATENODE.CS.INDIANA.EDU : VAX780 : \
	 UNIX : TCP/TELNET, TCP/FTP :

	and not:

	NET : 98.0.0.0 : APOLLO-RING :
	NET : 192.12.206.0 : IU-NET :
	GATEWAY : 98.0.0.1, 192.12.206.194 : DAPHNE.CS.INDIANA.EDU : DN560 : \
	 DOMAIN : IP/GW, GW/DUMB :
	HOST : 192.12.206.1 : GATENODE.CS.INDIANA.EDU : VAX780 : UNIX : \
	 TCP/TELNET, TCP/FTP :
	HOST : 98.0.0.1 : GATENODE.CS.INDIANA.EDU : VAX780 : UNIX : \
	 TCP/TELNET, TCP/FTP :

	I'm not sure if this caused a lot of problems with us since a lot of
	other things were messed up, but this works for us.

	Make sure and run makehost.sh after you make changes.

	If this file is messed up you usually get "Network Unreachable"
	types of errors.

2.	Make sure that you have a /sys/node_data[.*]/etc.inetd.conf file
	and that the right fields are uncommented.  Turned out we were
	running a few nodes with either no etc.inetd.conf file or one 
	that had EVERYTHING COMMENTED OUT.

	You usually get "Connection Refused" types of errors if this is
	wrong.

3.	Make sure that /etc/run_rc and /sys/node_data[.*]/etc.rc are
	BOTH mode 4755 (set uid to root).  The etc.rc is a bit of lore
	that I got from Apollo school.  Not sure if it is positively
	necessary, but I do it anyway.

	The idea is that lots of daemon must be run as root.  

4.	Make sure that you have PTYs in /sys/node_data[.*]/dev.  The
	best thing to do is:
			% cd /sys/node_data	/* or /sys/node_data.NNNN */
			% rm *ty*
			% /etc/crpty 16
	This will delete the old crusty PTYs and create fresh new ones.  

5.	Make sure that if you rlogin or rsh to an Apollo that the dots
	files (.rhosts, .login, .cshrc in particular) are owned by the
	correct person.  If you don't, you usually end up with either
	permission denied or an AEGIS shell.

6.	Make sure there are shell fields in /etc/passwd.

7.	Make sure that the GATEWAY runs /etc/routed via /sys/tcp/tcp_server -r
	and does not invoke it as /etc/routed anywhere.  Make sure that the
	non-Gateways do NOT invoke /etc/routed anyway/anyhow. [[THIS ONLY
	APPLIES IF YOU HAVE THE PATCH SINCE /sys/tcp/tcp_server -r IS PART
	OF THE PATCH]].

8.	If you have the patch, make sure all of your nodes are running with
	the patch version of tcp_server and that the gateway has the patch
	version of tcp_server, routed, rwho, and rwhod.  Make sure that all
	gateways are running this software too!  On bad gateway can ruin all
	of your routing tables.

	If you have questions or I've said something wrong, feel free to
correct me.  Anyway, hope this helps out if you are having TCP/IP problems.
