This is my new method ;-) and I can use ping :-)
I= f any thinks is ok, I can write it in the wiki.

Installing Plan9 network for QEMU (Linux)

Do you nee= d:

* Support for tunneling in kernel, with 802.1q:

tun: "N= etwork device support" -> "Universal TUN/TAP device driver sup= port"
bridging: "Networking options" -> "802.1d Ethernet Bridging"

* The bridge-utils package

First, lo= ad the Tunneling kernel support as modules

add "tun" to /etc/modules

Load it now (do= not reboot ;-)):=20 modprobe tun

* Create this= script:

darky:~# cat kixconf
IFACE=3Deth0
BRIF=3Dbr0
IPORIG=3D`/sbin/ifconfig $IFACE | grep = "inet addr" | cut -d: -f2 | cut -d" " -f1`
IPGW=3D`netstat -nr | grep ^" 0.0.0.0" | awk -F" " '{print $2} '`
IPBCAST=3D`/sbin/ifconfig $IFACE | grep "Bca= st" | cut -d: -f3 | cut -d" " -f1`

echo "Interface =3D " $IFACE
echo "Bridge if =3D " $BRIF
echo "IP =3D " $IPORIG
echo "Gateway =3D " $IPGW
echo "Broadcast =3D " $IPBCAST

ifconfig $IFACE down
brctl addbr $BRIF
ifconfig $I= FACE 0.0.0.0 promisc up
ifconfig $BRIF $IPORIG netmask 255.255.255.0 broadcast $IPBCAST up
brctl stp $BRIF off
brctl s= ethello $BRIF 1
brctl addif $BRIF $IFACE
route add default gw $IPGW
darky:~#

Now, configure /etc/qemu-ifup, and set the +x bit (chm= od 755 /etc/qemu-ifup) like this:

darky:~# ls -l /etc/qemu-ifup
-rwxr-xr-x 1 root root 60 2006-08-= 19 12:57 /etc/qemu-ifup
darky:~# cat /etc/qemu-ifup
#!/bin/sh
ifconfig $1 0.0.0.0 promisc up
brctl addif br0 $1
darky:~#
<= br>Now, you can use your Plan9 as a physical node in your network, then configure the Plan9 scripts as http://plan9.bell-labs.com/wiki/plan9/Network_configuration/index.h= tml

For boot the Plan 9 you shoud use this command:

/usr/bin/qemu -m 128 -hda '' -net nic,vlan=3D0,macaddr=3D00:11:22:33:44:55 = -net tap,vlan=3D0,ifname=3D -localtime &

2006/8/19, Ronald G Minnich < rminnich@lanl.gov>:
here's how I run qemu so as to get things going. This allow= s me to
drawterm into it.

qemu qemu.vesaroot &

Gets me a cpu = kernel going

sleep 5 && dhcpd -d

gets me the dhcpd
a run looks like this:

[root@q plan9]# qemu qemu.vesaroot &= sleep 5&& dhcpd -d

No subnet declaration = for ath0 (192.168.0.104).
** Ignori= ng requests on ath0.  If this is not what
    you want, please write a subnet declaration

Send= ing on   Socket/fallback/fallback-net
DHCPDISCOVER from 52:54:= 00:12:34:56 via tun1
DHCPOFFER on 172.20.0.2 to 52:54:00:1= 2:34:56 via tun1

DHCPACK on 172.20.0.2 to 52:54:00:12:34:56 via tun1


(note the DHCPREQUE= ST -- that's my plan 9)
(the error message is unimportant)

OK, wh= at's the config look like? dhcpd.conf:
subnet 172.20.0.0 netmask 255.255.255.0 {=
            = ;   range 172.20.0.2 172.20.0.2 ;
      = ;         default-lease-time 600;
            = ;      max-lease-time 7200;
  &n= bsp;            opti= on subnet-mask 255.255.255.0;
 = ;            &n= bsp;   option routers 172.20.0.1;
           &nb= sp; }
host qemu {
         hardwar= e ethernet 52:54:00:12:34:56;
       =   fixed-address xtest;
}

xtest is (from /etc/hosts):
172.20.0.2 xtest


ok but how did tu= n1 get configured? You need to set up /etc/qemu-ifup

[root@q etc]# cat /etc/qemu-ifup
#!/bin/sh
tun=3D$1
sudo /= sbin/ifconfig $1 172.20.0.1
sudo /sbin= /iptables -N nat
sudo /sbin/iptables -t nat -F
sudo /sbin/iptables -t= nat -A POSTROUTING -s=20 172.20.0.1 -j MASQUERADE
sudo /sbin/ip= tables -t nat -A POSTROUTING -d 172.20.0.1 -o $tun
sudo echo 1 > /proc/sys/net/ipv4/ip_forward
[root@q etc]= #


this allows me to drawterm into the plan 9 cpu server running o= n my laptop.

If this all works, then put it in the wiki :-) This is = on FC4.
