[9fans] Network Configuration

[9fans] Network Configuration

[Ray Amberg]

Hi everyone,

Thanks again for helping me get the Sis900-based ethernet card working on 
my machine.  I'm sorry to bother again, but I've got a new problem trying 
to get the machine configured to work on our network.  I've read through 
the Network Configuration wiki, and while I learned a few things, some 
things still remain cloudy (my networking knowledge is minimal too, 
apologies).

I have a Belkin router, which is located at 10.50.50.1 on the LAN, and 
whose computers start at 10.50.50.100.  There are a couple of other 
computers, using Windows and Linux, and they are automatically assigned
IP addresses when they connect to the router.  I think this is another way
of saying the router has its own DHCP server.  On a query of one of the
Windows machines, I found that the Gateway, DHCP Server, and DNS server 
were all 10.50.50.1, the address of the router.

Trying to make sense of the Network configuration wiki, I added the 
following to my /lib/ndb/local file:

ip=10.50.50.104  ipsubmask=255.255.255.0
 	ipgw=10.50.50.1
 	dns=10.50.50.1

I manually put in 10.50.50.104, and have a feeling I shouldn't be doing 
this.  In any case, the result was a failure.  The plan9 machine can ping 
itself at 10.50.50.104, but can't ping 10.50.50.1.  DNS queries fail with 
the error: dns: temporary failure.

I tried looking through previous 9fans posts for ways to configure a 
simple connection to a router, unsuccessfully.

Would someone be so kind as to help me find a way to get the ethernet 
card connected to the router, and hence, the internet?  Apologies again, 
I'm not exactly sure what I'm doing.  Thanks for your time.

Sincerely,
Ray Amberg

Hello..

I'm a newbie... :p

Take a look at your /rc/bin/termrc ? seems necessary to address a DHCP..

I'd recommend choosing an address outside of the dhcp pool of
addresses; for instance 10.50.50.94. Modify /lib/ndb/local to reflect
the change. Add the following to either your termrc or cpurc
configuration file:

     ip/ipconfig -g 10.50.50.1 ether /net/ether0 10.50.50.94 255.255.255.0

Review the termrc or cpurc configuration file and ensure the following
is stated:

     /ndb/dns -r

For testing purposes, try modifying the /lib/ndb/local file as
suggested then run the two commands before modifying any other files.
If you can connect at that point then add the commands to your
configuration.

Re: [9fans] Network Configuration

[Ray Amberg]

Thanks for the response.  I edited my /lib/ndb/local to look like this:
 	ip=10.50.50.94 ipsubmask=255.255.255.0
 		ipgw=10.50.50.1
 		dns=10.50.50.1

And here's the result of the commands suggested:
 	% ip/ipconfig -g 10.50.50.1 ether /net/ether0 10.50.50.94 
255.255.255.0
 	% ndb/dns -r
 	% ssh eon.cs.ucr.edu
 	ssh: dialing eon.cs.ucr.edu: cs: temporary problem: dns: dns 
failure

This error message occurs after a long pause.  I also still cannot ping 
the router.

What do you see when you ping 10.50.50.94?

I'll transliterate the mu symbol as an M.

this is my sujestion:

in /lib/ndb/local

ipnet=your-net ip=10.50.50.0 ipmask=255.255.255.0
      sys=my-system

then uncomment this in /rc/bin/termrc or /rc/bin/cpurc :

#if(! test -e /net/ipifc/0/ctl)
#	ip/ipconfig >/dev/null >[2=1]

Re: [9fans] Network Configuration

[Ray Amberg]

Thank you for the suggestion.  I changed the entry in /lib/ndb/local to 
look exactly as you specified, then uncommented the lines in /rc/bin/termrc.

When I restarted the computer and logged in, it hanged for a long time, 
and then said this before starting up:
init: starting /bin/rc
ndb/dns: can't read my IP address

And then of course, I could not ping anything.

Re: [9fans] Network Configuration

What driver are you using, ethersis.c or ether83815.c?
I ask this becase I couldn't get the 83815 driver to work
properly for my sis 900.

try changing the ipconfig line in your termrc to:
ip/ipconfig -DG

btw, as stated in plan9.ini(8) the 83815 driver doen't set
the right ethernet address for the sis 900 , so I added:
ether0=type=83815 ea=xxxxxxxx
then, ip/ipconfig worked, but I couldn't ping anywhere
and I didn't get an error message, so I'm still using ethersis.c.

I'm still using the ether83815.c driver.  I think I am running into the 
same problem that you had, because ipconfig now works, but I can't ping 
anywhere, really.

I'll give the ethersis driver a shot and post the results.

Upon recompiling the kernel with the line:

and putting the following in /lib/ndb/local:
ipnet=my-net ip=10.50.50.0 ipmask=255.255.255.0

I was able to ping the router and get connected to the internet.  Thanks 
for the help!

if i can find something with the SIS chipset i'll see if i can
put any required code into ether83815.c.
that one supports only the cards i had.

Re: [9fans] Network Configuration

[andrey mirtchovski]

i wrote the ethersis.c driver back in 2002 but never submitted it for
inclusion because i only tested it on the one on-board card i had
available. indeed i haven't had any other SIS cards since then.

charles, if you want to incorporate ethersis into ether83815 you're
welcome to :)
