Re: [9fans] Help with networking on Virtual Box

[Patryk Laurent <plaurent@me.com>]

Hi Peter,

I had the same DNS issue under VirtualBox. Here is my procedure after every reboot (I am new to plan9 so there may be a better way):

1. Run ip/ipconfig
2. cat /net/ipselftab to find your VM's internal ip (10.0.x.x?)
3. Set your IP in /lib/ndb/local  ip = …
4. Run ndb/dns -r

I don't know enough about plan9 to know why this is necessary.  I pieced this procedure together using the docs and help from the IRC channel. 

Plan9 is really cool though -- enjoy!

Best,
Patryk
