[9fans] Plan9 CPU server

[9fans] Plan9 CPU server

[Nyan Htoo Tin]

Hi all, I've successfully tried plan9 on qemu/virtualbox.
But I don't understand what is CPU server that I usually saw in plan9
doc/manual??
I'd like to know details...link/pointer would be appreciated.

I've downloaded http://www.9gridchan.org/9grid_node_img and used
drawterm.
But I have no idea how to connect from plan9 machine.
Let's say after I've booted CPU server using this command
 qemu -hda ventigridserver.qcow2.img -redir tcp:2567::567 -redir tcp:
17010::17010 -m 256

I could use drawterm. But How do I connect from another plan9 machine?
I've tried cpu -h gridserver but not successful....

I'm not sure about the 9gridchan images in particular, but if you're
trying to connect from another Plan 9 machine, *in general*, you want
to add some stuff to /lib/ndb/local. If your cpu/auth server is called
gridserver, the computer you want to connect *from* should have
entries something like this:

auth=gridserver authdom=yourauthdomain

sys=gridserver dom=gridserver.yourauthdomain ip=<its IP>


Then you can do cpu -h gridserver.

Hope this helps

After I start qemu with

 qemu -hda ventigridserver.qcow2.img -redir tcp:2567::567 -redir tcp:
17010::17010 -m 256
I start again this time with: qemu -hda ventigridserver.qcow2.img
The one I want to connect *from* /lib/ndb/local file has these lines
also:
authdom=the9grid auth=gridserver
.....
sys=gridserver authdom=the9grid
    auth=gridserver
When I do cpu -h gridserver,
cpu: can't dial: gridserver: cs: can't translate address: dns:
resource does not exist

Thanks for your help...

You might want to read http://plan9.bell-labs.com/sys/doc/9.html in
order to learn more about the distributed nature of plan9.

1. I really do not think it is a good idea to boot two instances of
qemu using the same hard disk
2. After you boot the second system (preferably by making a copy of
the disk image), try running "ip/ipconfig" and "ndb/dns -r" just for
kicks and giggles. Oh, and put an ip= field into your /lib/ndb/local,
in this case I think you might need it.

And then if that doesn't work, just use drawterm the way the site
recommends. It'll also make your qemu CPU server run faster.
