 Posted: Fri Nov 07, 2008 9:15 am Post subject: Virtual Box -- automatically get ip |
 |
|
hello everyone...
Id like to have a initscript of my eth0 device that gets the IP automatically and forwards the settings for my VirtualBox (Bridge connection) cause I'm learing as a networkegineer but have no knoledge about programming.
Who can help me??
and here's my /etc/conf.d/net.eth0
| Quote: | # This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d. To create a more complete configuration,
# please review /etc/conf.d/net.example and save your configuration
# in /etc/conf.d/net (this file :]!).
#config_eth0=( "192.168.1.56 netmask 255.255.255.0 brd 192.168.1.255" )
#routes_eth0=( "default via 192.168.1.1" )
config_eth0=( "dhcp" )
# dhcp_eth0="nodns nontp nonis"
#######################################
### virtual machine####################
# For every VM create an interface,
# set user to the one who going to use the
# interface.
tuntap_vbox0="tap"
tunctl_vbox0="-u fysi"
config_vbox0="192.168.1.56"
# config_eth0="null"
# Add here all interfaces that you want to bridge
# eg eth0, but make sure to add config_eth0="null"
rc_need_br0="net.vbox0"
bridge_br0="vbox0 eth0"
# The following will be the host IP, it can be the default router
# for the VM in routing mode.
# You can use dhcp here if you like, it makes sense if you want
# to bridge your VM into the real network.
config_br0="dhcp"
#config_br0="192.168.151.1/24"
brctl_br0="setfd 0
sethello 0
stp off"

Rename /etc/conf.d/net.eth0 into /etc/conf.d/net and create a symlink /etc/init.d/net.vbox0 that points to /etc/init.d/net.lo:
| Code: | mv -i /etc/conf.d/net.eth0 /etc/conf.d/net
ln -s net.lo /etc/init.d/net.vbox0 |
Also make sure you added support for bridging in your kernel configuration:
| zgrep '^CONFIG_BRIDGE=' /proc/config.gz: | | CONFIG_BRIDGE=m |
or
| grep '^CONFIG_BRIDGE=' /usr/src/linux/.config: | | CONFIG_BRIDGE=m |
EDIT: Also uncomment
| Code: | | # config_eth0="null" |

well the symlink was alredy created...
the module was already loaded[quote]grep '^CONFIG_BRIDGE=' /usr/src/linux/.config
CONFIG_BRIDGE=y
heres my new /etc/conf.d/net
| Quote: |
config_eth0=( "dhcp" )
# dhcp_eth0="nodns nontp nonis"
#######################################
########### virtual machine ###########
# For every VM create an interface,
# set user to the one who going to use the
# interface.
tuntap_vbox0="tap"
tunctl_vbox0="-u fysi"
config_vbox0="dhcp"
# config_eth0="null"
# Add here all interfaces that you want to bridge
# eg eth0, but make sure to add config_eth0="null"
rc_need_br0="net.vbox0"
bridge_br0="vbox0 eth0"
# The following will be the host IP, it can be the default router
# for the VM in routing mode.
# You can use dhcp here if you like, it makes sense if you want

config_br0="dhcp"
#config_br0="192.168.151.1/24"
brctl_br0="setfd 0
sethello 0
stp off"

I think the problem is caused by the following line of startup
| Quote: |
...
creating bridge br0.... [OK]
adding ports to br0
network interface vbox0 does not exitst
please verify hardware or kernelmodule (driver) [!!!]
starting eth0
....
|
so internet works on my gentoo but not on virtual box...
thanks for your help

First your bridge is still badly configured: your eth0 is configured to receive an address from DHCP. All interfaces that are part of a bridge *must* have their config_iface variable set to "null":
| Code: | config_vbox0="null"
config_eth0="null" |
Next you should have these symlinks in /etc/init.d/:
| ls -l /etc/init.d/net.*: | lrwxrwxrwx 1 root root 6 aoû 31 00:33 /etc/init.d/net.br0 -> net.lo
lrwxrwxrwx 1 root root 6 aoû 27 00:00 /etc/init.d/net.eth0 -> net.lo
-rwxr-xr-x 1 root root 14682 oct 15 13:30 /etc/init.d/net.lo
-rwxr-xr-x 1 root root 2074 oct 15 13:30 /etc/init.d/netmount
lrwxrwxrwx 1 root root 6 aoû 27 14:15 /etc/init.d/net.vbox0 -> net.lo |
You should also make sure that module tun gets loaded at boot -- udev doesn't load it automatically, you have to add it to /etc/conf.d/modules if you have baselayout-2* (it looks like that's what you have):
| /etc/conf.d/modules: | | modules_2_6="${modules_2_6} tun" |
Add net.br0 to any runlevel (default for instance) and add this to your /etc/conf.d/net:
| /etc/conf.d/net: | depend_br0()
{
need net.eth0
need net.vbox0
} |
Hope I forgot nothing .

What exactly doesn't work? If you have an error message, please post it here.
EDIT: Also post the results of ls -l /dev/net/tun. You should get:
| ls -l /dev/net/tun: | | crw-rw-rw- 1 root root 10, 200 nov 18 08:49 /dev/net/tun |
If this is not what you have, check /etc/udev/rules.d/50-udev-default.rules:
| grep tun /etc/udev/rules.d/*: | | /etc/udev/rules.d/50-udev-default.rules:KERNEL=="tun", NAME="net/%k", MODE="0666", OPTIONS+="ignore_remove" |
