[9fans] fossil+venti install and network?

[csant]

I feel like an echo from the past.

	http://9fans.net/archive/2005/07/308

Same here - I had the network correctly configured on a fossil only
system, I re-installed everything, this time with fossil+venti.
Re-configured everything according to the detailed notes I took, so the
system is configured in the same way. However, I get the same
	ndb/dns cannot read my ip address

The above thread has a few suggestions, but none of them work, and I don't
seem to find a final "yes, it worked" reply. Well, it doesn't, for me. Is
networking done in some different way, when running fossil+venti rather
than just fossil? What am I doing wrong now?

/c :)

i'm not quite sure what your problem is.  but it looks like myipaddr() is bombing out.
you don't even seem to have a loopback address configured.

what does "ns | grep /net" give you?  you should have at least this:

bind  /net /net
bind -a '#l' /net
bind -a '#I' /net
mount -a '#s/cs' /net

(assuming you have an ethernet card. ;-))

Yessir, I do - exactly that.

Two of them: one doesn't seem to be recognized, though:

	term% ls /net/ | grep ether
	/net/ether0

Heia,

thanks to Sascha Retzki for pointing me into the right direction:
In /rc/bin/termrc I had the following:
	if(test -e /net/ipifc/0/ctl)
		ip/ipconfig >/dev/null >[2=1]
and
	if(test -e /net/ipifc/0/ctl)
		ndb/dns -rf $NDBFILE
which caused failure. The tests are there by default. I removed the tests  
and have now only
	ip/ipconfig >/dev/null >[2=1]
	ndb/dns -rf $NDBFILE
and everything works fine.

Why was the test working fine with a fossil only system, but not with  
fossil+venti?

The tests are failing because there is an ip device bound to /net/ipifc/0
before termrc is run. In this case it's a loopback device started by the
kernel for venti to listen on. In a fossil only system the loopback device
is not started and the tests succeed.

My cpurc (based on one from the labs) does this:
---
# site-specific startup
if (test -e /rc/bin/cpurc.local)
	.   /rc/bin/cpurc.local

#  [...]

# cpu-specific early startup, notably cron
if (test -e /cfg/$sysname/cpurc)
	.   /cfg/$sysname/cpurc

#  [...]

# start up internet if we don't already have an address
if(! grep u /net/ipselftab | grep -sv 127.0.0.1)
	ip/ipconfig
if(! grep -s 127.0.0.1 /net/ipselftab)
	ip/ipconfig loopback /dev/null 127.1
---

which should be more robust.

One of my current tasks is to simplify administration.  I'll be back
at the labs tomorrow (Monday) and will look into why we don't have
a similar cpurc nor /cfg on sources.  At minimum, one wants /cfg/pxe for
pxe booting.

I find it strange:
   after setting up /lib/ndb/local and 'ip/ipconfig -g..'
   line in /rc/bin/termrc and reboot

the system on reboot keeps complaining:
    ndb/dns cannot read my ip address

and hence no network. I have compared the above mentioned
files with working fossil only installation..

[Steve Simon]

you need to make sure your ip/ipconfig line is above the

if(test -e /net/ipifc/0/ctl)
	ndb/dns -rf $NDBFILE

entry so dns ios started properly.

alternatively you could add ipconfig to /rc/bin/termrc.local which is
"dotted" (read included) into termrc in an apropriate place.

It is! I will try to redoit the whole installation.

I did try that too.

Thanks for the response.

Iswar,

Depending on your needs, an alternative solution is to add something
similiar to the following in your /rc/bin/cpurc file:

sysname='{cat/dev/sysname}
switch($sysname){
case iswar
     ip/ipconfig -g 192.168.0.1 ether /net/ether0 192.168.1.20 255.255.255.0
     ndb/dns -r
case rattan
     ndb/dns -srn
case *
     ndb/dns -r
}
