[comp.unix.questions] Mt Xinu 4.3BSD and two DEQNA's?

ernie@nucsrl.UUCP (Ernest Woodward) (08/26/87)

	In the past I requested information about the use of two DEQNA's on
ULTRIX v1.2 and 4.3BSD and had received several replies with good information.
Unfortunately, a system crash lost those mail notes and I was not able to
send information back to specific individuals. Now I have a similar problem
with the Mt Xinu's 4.3BSD and I thought I would post a note with another
question and also supply some information of the past experiences.

	As mentioned by several respondents of my ULTRIX question, when
booting off a kernel with a name other than /vmunix (e.g. /vmunix.new), the
'ps', 'netstat', etc. output does not get generated at the standard output
file. I was able to run ULTRIX v1.2 with two DEQNA's and everything worked
normally, as long as I booted off the kernel named /vmunix.

	My initial problem with use of two DEQNA's on the 4.3BSD system was
caused by the following statement:
	/etc/ifconfig qe0 inet xx.xx.xx.xx broadcast xx.xx.xx.xx up -trailers
The 'up' argument on this initial ifconfig command will cause the kernel to
panic. As mentioned by the respondents of my 4.3BSD-2 DEQNA's question, the
up argument should not be used on the initial ifconfig.

	I have now installed the Mt Xinu's 4.3BSD and have the following
set of statements in my /etc/rc.local file concerning ETHERNET:
	/etc/ifconfig lo0 localhost
	/etc/ifconfig qe0 inet 192.26.85.1 broadcast 192.26.85.0 -trailers
	/etc/ifconfig qe1 inet 128.174.5.131 broadcast 128.174.5.0 -trailers
I am able to boot the kernel up into single-user mode and perform several
basic functions. I have been able to run ping over the qe1 ethernet and
run all network utilities over the qe0 ethernet. The qe1 ethernet does not
have enough currently active hosts to perform other networking tests.
When I bring up multi-user mode, all the daemons get activated and the login
prompts are available. Once a person log's on, they are shown /etc/motd and
they get hung before the shell can give them a prompt. If I bring the
system up with only the qe0 ethernet (i.e. remove the ifconfig qe1 statement
from /etc/rc.local file), everything runs fine. As soon as I enter the
/etc/ifconfig qe1 inet ... line, several (and maybe all) processes hang.

	I am using the MicroVAX II as a gateway machine to ARPANET and
two ethernets. I am therefore running with two DEQNA's and ACC's ACP5250
(X.25 board for the qbus). I am running with the named and egp. I am not
currently using routed, instead, we use /etc/route add defaults in
several hosts on the network. I am concerned that there is some file 
somewhere in the system that limits the use of sockets or something unknown
to me. If anyone has an idea, please send the information to:

	ernie@eecs.nwu.edu
or	ernie@accuvax.nwu.edu
or	ernie@nuacc.bitnet

	Thanks to all the people who have sent me some extremely valuable
information in the past.
