 |
|
My box has no IP set for both eth0 or eth1.
| Code: | eth0: flags=4419<UP,BROADCAST,RUNNING,PROMISC,MULTICAST> mtu 1500
ether 00:25:90:6e:94:fc txqueuelen 1000 (Ethernet)
RX packets 15846113197 bytes 21025107832049 (19.1 TiB)
RX errors 0 dropped 1199261 overruns 27 frame 0
TX packets 11872464826 bytes 11768381533276 (10.7 TiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device memory 0xfb920000-fb940000
eth1: flags=4419<UP,BROADCAST,RUNNING,PROMISC,MULTICAST> mtu 1500
ether 00:25:90:6e:94:fd txqueuelen 1000 (Ethernet)
RX packets 24656507833 bytes 2893130107855 (2.6 TiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 24562942737 bytes 5552907337463 (5.0 TiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device memory 0xfb900000-fb920000

However I do have 2 bridge devices into which eth0 and eth1 are assigned in /etc/conf.d/net.
| Code: | bridge_br0="eth0 b0x00 b0x01 b0x02"
bridge_br1="eth1 b1x00 b1x01 b1x02" |
Now when I want to launch postfix I get the following strange and rather unwanted behaviour.
| Code: | ~ # /etc/init.d/postfix start
* Caching service dependencies ... [ ok ]
* Bringing up interface eth0
* No configuration specified; defaulting to DHCP
* dhcp ...
* Running udhcpc ...
* start-stop-daemon: failed to start `/bin/busybox' [ !! ]
* ERROR: net.eth0 failed to start
* Bringing up interface eth1
* No configuration specified; defaulting to DHCP
* dhcp ...
* Running udhcpc ...
* start-stop-daemon: failed to start `/bin/busybox' [ !! ]
* ERROR: net.eth1 failed to start
* Starting postfix ... [ ok ]
|
It seems that postfix is happy about the system and seems to be able to deal with mail. However I would rather not fire up udhcpc in the process.
Any hints anyone on how to prevent udhcpc from being launched?
Cheers,

guid0 ...
"you need to configure the ports to null values so dhcp does not get started", see the section "Bridging" in /usr/share/doc/openrc-<version>/net.example.bz2
| Code: | config_eth0="null"
config_eth1="null" |
