How can i get the network working with 9vx

[pmarin]

Hi all.
I am trying to use the 9front iso image [1] with 9vx and I get the
following error:
grep: can't open /net/ipselftab: '/net/ipselftab' cs: file does not
exist
ndb/dns: can't read my ip address

With 9atom and plan9 the networking works out of the box.

[1] 9front-943.31a104b0a861.iso

Cheers.

Are you using any virtual ethernet device with 9vx? Because if you are
not, 9vx will use the ip stack of the host. In this case, 9vx /net
will include some files, but ipselftab is not one of them.

You will also get errors if you try to run ndb/dns or ip/ipconfig from
a 9vx booted with 9atom or plan9. The difference is that they do not
try to start the network by default.

You could comment a few lines in termrc to avoid the error. Networking
should be working fine.

added issue to bugtracker here:

http://code.google.com/p/plan9front/issues/detail?id=93&colspec=ID%20Type%20Status%20Priority%20Milestone%20Owner%20Summary%20Subsystem

i dont have a linux installation to test right now...

as you describe it, seems to be mostly a matter of detecting 9vx and not
doing ip/ipconfig and dns at all because 9vx provides these files for you
in #I right?

A solution would be to test if $sysname is 'vx32' AND there is no
/net/eth0. You probably want to start the network if you are using
virtual ethernet devices.

I don't have a 9front tree in my 9vx machine just now, but I will try later.

$sysname may be set before any scripts are run. 9vx can use some
equivalent of plan9.ini.

You are right, an user could overwrite the value of sysname. A better
test to know if we are inside 9vx may be to check for '#Z'

Let's just run 8l 10 times and see if it crashes at once point ...
