 Posted: Sun Jun 19, 2005 8:53 pm Post subject: new baselayout and tun/tap [solved] |
 |
|
I'm using a bridge and a tun/tap device to communicate with an instance of user mode linux (UML). My configuration already worked fined with the 'old' baselayout.
I switched to the new baselayout recently. Since then I can't connect the UML instance via the net any more, while the bridge itself is functional after editing the /etc/conf.d/net, so I can connect my box from other machines on the local net.
I suspect the problem with the tun/tap mechanism because I found in the log of the UML instance the error TUNSETIFF failed, errno=1.
These are the relevant lines from my /etc/conf.d/net:
| Code: | brctl_br0=( "setfd 0" "sethello 0" "stp off" )
bridge_br0="eth0 tap0"
config_br0=("192.168.222.105 broadcast 192.168.222.255 netmask 255.255.255.0")
routes_br0=("default gw 192.168.222.104")
config_tap0=("null")
config_eth0=("null")
depend_br0() {
need net.eth0 net.tap0
}
|
All /etc/init.d/net.* are symbolic links to /etc/init.d/net.lo
TIA!
Matthias

I have a similar setup. Here is my new /etc/conf.d/net file. I've been using the new baselayout a while now and never had any troubles.
| Code: | # /etc/conf.d/net:
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/conf.d/net,v 1.7 2002/11/18 19:39:22 azarah Exp $
# eth0 : WAN
# eth1 : Untrusted wireless network
# eth2 : Trusted wired network, bridged with tap0 / Zero configuration segment
# tap0 : OpenVPN clients from untrusted network, bridged with eth2
# br0 : Ethernet bridge of trusted wired network and VPN clients from wireless.
# Globals
modules=( "iproute2" )
# WAN Interface
config_eth0=( "dhcp" )
fallback_eth0=( "192.168.100.11/24" )
# Untrusted wireless network
config_eth1=( "172.25.2.254/24" )
# Trusted wired network and bridge
config_eth2=( "null" )
config_tap0=( "null" )
bridge_br0=( "eth2 tap0" )
brctl_br0=( "setfd 0" "sethello 0" "stp off" )
config_br0=( "172.25.1.254/24")
depend_tap0() {
need openvpn net.eth1
}
depend_br0() {
need net.tap0 net.eth2
}

I don't see anything more than minor syntatic differences, really.

thank you for your reply, bigfunkymo
It turned out that the problem was a dependency issue. If I make sure that the tuntap-devices are created before the UML is started, everything works like charm.
BTW: I really like the new net-configuration. |

Me too but I would like to have something like:
| Code: | n22 ~ # cat /etc/conf.d/net
# net.eth0
config_eth0=("dhcp" || "adsl")
dhcpcd_eth0="-t 15"
dhcp_eth0="nontp"
|
So at work I would get an ip adress from the dhcp server where at home the system automatically connects to my ISP immediately after dhcp failed.
Anything planed for the future in this direction ? |
