ADDITIONAL INFORMATION IN INSTALLING THE LINUX XKERNEL TO BOOT THE SUN
3/50

These notes are to be read in conjunction with the document explaining
how to setup the linux Xkernel. It can be found at:
http://www.sfn.saskatoon.sk.ca/~aa113/README.txt. If not there, then email
martin@kaveri.eas.asu.edu and ask for a copy. You will need only that
document and these notes here to setup a Sun 3/50, even if you are an
amateur as I was before!

Some things before starting
---------------------------

If you are going to use thin ethernet, use 50Ohm terminators and T
junctions. CHECK whether your Sun is jumped to use AUI Ethernet or BNC
connector(thin ethernet). The jumpers are 8, onto a red panel , and if you
are going to use thin ethernet, push all 8 to ON(up) or if you are
connecting it through AUI ethernet, push all 8 down(OFF). Check this; it
might save you a lot of problems. If you get a no carrier message when
requesting the IP address, then this is your problem.  

Let the Sun run its self testing. If one led is blinking at the end of the
tests, then everything is fine. Else consult the hardware FAQ on what the
problem might be. 

If you linux box has NE2000 network card, it will probably not be
compatible with the Sun. I boot mine using an etherexpress card. Use this
one if you can, for sure!

Read RFC1597 to put the correct addresses to your computer. DO NOT USE ANY
NUMBER YOU THINK, e.g. 152.34.78.123. Use numbers preferably starting with
192.168.23.xxx(0<xxx<256), if you are building your own small net in your
house. Else ask the network administrator to assign a number to you. BUT
DO READ RFC1597!!!

Things related to the document


EXTRACTING
csh or tcsh shell must run for the zcat... command to work. Else cd/usr
and tar -xvf linux-xkernel.tar.gz

1. Setting up hosts files

/etc/hosts on my computer would be

127.0.0.1 	localhost localhost.localdomain
192.168.23.10 	gmsparc.private.mynet.com gmsparc server
192.168.23.11 	xhost	gmsun

and 
usr/export/root/Xkernel.sun3/etc/hosts would be

192.168.23.11 	xhost
192.168.23.10 	primaryxdmhost server loghost fontserver

2. Setting up rarp
To see if rarp is installed use rarp -a and see if the computers are
listed. Put rarp -s ... into rc.local for sure!!!

3. This is an easy step to do; just read the notes on the main document

4. This is also an easy step; follow the relevant instructions

5. Your already installed versions of rpc.nfsd and rpc.mountd (either
Slackware or Redhat) will NOT work. You will have to compile the ones
provided with the Xkernel. To do this the instructions say that you should
do

./configure 
and then make.

Make in my computer did not  work, and gave me some errors. What I did was
I debugged the errors. Following are the main error ?I got:

>make
....
...
..
nfs_prot_xdr.c: In function `xdr_nfs_fh':
nfs_prot_xdr.c:78: parse error before `int'
make: *** [nfs_prot_xdr.o] Error 1

to fix this  I deleted the line 78 which contained the int i; (which
apparently in that function is not used at all) and rerun make(if you
run make clean, and then make you will again meet this error, and you will
have to fix it again). 
Finally, copy the two generated files to the already existing ones, and
restart, as noted in the main document.

6. Setup xdm as described in the main document

7. Setup up the font server, not the other(the font server is more
reliable and better to use, and easier of course to install)

8. So setup up the font server

9. Do not setup the NFS fonts

10. Test it. If you have done everything correctly as described in the
main document and as described in this notes, then everything should be
fine.
