Hi,

I have following problem: dhcpcd fails at always boot but it usually works fine when the boot ends. I need it working from the begging since I mount some nfs resources. I tried various versions of dhcp clients but the problem remains. I would be grateful for any tips. These might help:

Code:

 * Bringing up interface eth0
 *   dhcp ...
 *     Running dhcpcd ...
dhcpcd[13996]: version 5.5.6 starting
dhcpcd[13996]: all: not configured to accept IPv6 RAs
dhcpcd[13996]: eth0: waiting for carrier
dhcpcd[13996]: eth0: carrier acquired
dhcpcd[13996]: eth0: rebinding lease of 10.42.1.130
dhcpcd[13996]: eth0: broadcasting for a lease
dhcpcd[13996]: timed out
dhcpcd[13996]: allowing 8 seconds for IPv4LL timeout
dhcpcd[13996]: eth0: probing for an IPv4LL address
dhcpcd[13996]: eth0: checking for 169.254.203.111
dhcpcd[13996]: timed out
 [ !! ]
 [ !! ]
 * ERROR: net.eth0 failed to start


When it works:
Code:

dhcpcd[15449]: version 5.5.6 starting
dhcpcd[15449]: all: not configured to accept IPv6 RAs
dhcpcd[15449]: eth0: rebinding lease of 10.42.1.130
dhcpcd[15449]: eth0: acknowledged 10.42.1.130 from 10.42.0.6
dhcpcd[15449]: eth0: checking for 10.42.1.130
dhcpcd[15449]: eth0: leased 10.42.1.130 for 3600 seconds
dhcpcd[15449]: forked to background, child pid 15487                      [ ok ]
 *     received address 10.42.1.130/17                                    [ ok ]


My /etc/conf.d/net file contains only:
Code:

Is this a 100% wired path? Is there wireless involved anywhere?

I would suggest: --noarp

From: man dhcpcd

Unfortunately it didn't help:
Code:

Necro-post, I know, but I am having the exact same issue as the OP, but on my entire subnet. At my office, we have a single DHCP server which hosts multiple subnets. When I connect any of my Gentoo boxes to subnet A, they have no problem rebinding a lease, but when they are connected to subnet B, I get the same weird error as the OP. As you can imagine, this wreaks havoc with many of the web services I need to start at boot. Having to manually restart all of these services each time I reboot is a pain, and a real problem if the server were to go down at a time when I could not access it locally.

Any ideas on what could be causing this, or where I could look for more info?

Thanks!

I've got a similar problem:

* Bringing up interface enp0s4
* dhcp ...
* Running dhcpcd ...
dhcpcd[1211]: version 6.2.0 starting
dhcpcd[1211]: DUID 00:01:00:01:1a:82:40:83:00:0e:a6:39:c9:50

dhcpcd[1211]: enp0s4: rebinding lease of 10.136.229.237
dhcpcd[1211]: enp0s4: DHCP lease expired
dhcpcd[1211]: enp0s4: soliciting a DHCP lease
dhcpcd[1211]: timed out
dhcpcd[1211]: allowing 8 seconds for IPv4LL timeout
dhcpcd[1211]: enp0s4: probing for an IPv4LL address
dhcpcd[1211]: enp0s4: offered 10.136.229.237 from AAA.BBB.CCC.DDD
dhcpcd[1211]: timed out
dhcpcd[1211]: exited
[ !! ]
[ !! ]
* ERROR: net.enp0s4 failed to start

Already emerged dhcpcd with -ipv6 and already tried adding a delay of 3 seconds in the preup.
Problem persists. Anyone got any ideas?

I was having this exact issue with dhcpcd timing out on boot. I 'fixed' it by switching the driver to be a module instead of compiled in.

I realise this is odd and subjective so YMMV. For me the problem was random but seemed to happen more often then not. Since I switched it hasn't happened once, this was two weeks ago with a power cycle at least once a day. Don't know if it's a coincidence but it's an easy thing to try.

Edit: btw the driver was e1000e

My driver for the net card is already loaded as a module (sis900 in my case). The problem must be something else.
I concluded that if I remove the file /var/lib/dhcpcd/netXXX.leases before starting the dhcpcd service, it always succeeds at getting an address, although it takes something like 20 or 30 seconds.
