Full Text Bug Listing

After upgrading baselayout (1.12.0_pre17-r3) and udev (090), the network
scripts no longer work correctly.

My computer has three onboard ethernet ports. I use eth0 for the connection to
the LAN and eth2 for the cable modem. eth0 has a static configuration and eth2
uses dhcp.

The problem occurs when bringing up net.eth2. The dhcp-client program tries to
setup _all_ interfaces, not just eth2. This destroys the configuration on eth0. 

If I bring up eth2 first then eth0, both interfaces work but I lose the
resolv.conf from dhcp.

post your /etc/conf.d/net file

also, are you using hot or cold plugging ?

Why would udev matter in this?

If you go back to 089 version of udev, does this get fixed?

I only mentioned this because it changed at the same time. Also this is the
first time I've used the new scripts that use udev for coldplug. udev was
trying to bring up net.eth1 when the system booted, but I figured out how to
fix that.

my /etc/conf.d/net:

config_eth0=( "192.168.1.4 netmask 255.255.255.0 broadcast 192.168.1.255" )
config_eth2=( "dhcp" )

Neither for the ethernet devices. I changed /etc/conf.d/rc to not allow
coldplugging of net.*

What version of dhcp have you got installed?

Try 3.0.3-r7

This corrects the problem.

I'm having similar problem. I have 2 interfaces: eth_wan0 configured using
ISP's dhcp and eth_lan0 with static IP. I'm running local dhcpd for subnet on
eth_lan0 too. When net.eth_wan0 is started, dhclient is run and it reconfigures
eth_lan0 using local dhcpd server provided IP. I got this problem after
upgrading baselayout from 1.11.15 to 1.12.4-r2. I have installed dhcp-3.0.3-r9.

Appending "${iface}" to dhclient commandline in /lib/rcscripts/net/dhclient.sh
on line 109 fixed the problem. But it's probably only hack, not a bugfix.

No, that's the correct fix. I cannot believe that no-one has spotted that!
Including me!

Will be in the next baselayout release.

Fixed in baselayout-1.12.4-r3
