Getting Multiple Copies of dhcpcd for Same Network Card


Hi,

I've got a strange problem when I re-boot my machine. The machine has 2 network cards, an old ne2000 that connects to my cable modem and a NatSemi for the internal network. Both cards are 'modprobed' from rc.netdevices, and work perfectly. But, I'm seeing multple copies of dhcpcd being spawned off for the ne2000 card. (The NatSemi has a static IP). It's usually 2 copies that start, but occaisionally, I see 3. Here's what I see today, from a "ps -ef":

root 96 1 0 Mar07 ? 00:00:00 /sbin/dhcpcd -t 10 -d -R eth0
root 98 1 0 Mar07 ? 00:00:00 /sbin/dhcpcd -t 10 -d -R eth0

I've checked the rc.inet1 script, and that has NOT been modified from the initial install. There is only one place that dhcpcd gets called. The rc.inet.conf file looks correct, as it only has dhcp=yes for the ne2000.

If I run rc.inet1 from a command prompt, it ALWAYS only starts a single copy of dhcpcd.

I've tried to debug the scripts at boot time, but am having a couple of problems with that. (See my other post).

Any ideas why dhcpcd wants to start more than once.

Cheers,
Eddie

I know I posted this reply in my other question, but I think it's more appropriate here:



Well, after a bunch of searching around on my system, I found a 2nd place where rc.inet1 is called. It's also called from /etc/hotplug/net.agent. And the only change I've made recently was to enable rc.hotplug so my USB ports are available at boot time for a UPS.

And guess what else I found. This in a SuSE sysconfig package changelog:

- is_iface_available(): It will now only modprobe <interface> if called from ifup, because it must not trigger unwanted hotplug events (#13178, dhcpcd was started twice)

Looks like Slack has the same bug. As long as I can work out what that cryptic comment means.

Cheers,
Eddie
