Description:DHCPCD 9.0.1-2 used with IWD

I had an IP address, no name resolution.
After several reboots I downgraded to 8.1.7-1 which resolved it.

Apr 19 12:04:11 carlos dhcpcd[866]: ps_dostop: Connection
refused

resolv.conf while it's broke..

# Generated by dhcpcd from wlan0.dhcp
# /etc/resolv.conf.head can replace this line

resolv.conf after downgrade..

# Generated by dhcpcd from wlan0.dhcp
# /etc/resolv.conf.head can replace this line
domain Home
nameserver 192.168.1.1
# /etc/resolv.conf.tail can replace this line

@arojas

Done.

Comment by Mal Haak (insanemal) - Monday, 20 April 2020, 05:17 GMT

Just to add to this, it also breaks routing.

@John Barks

Can you please link the upstream ticket

Downgrade fixes it... I'm not sure it's "just" a DHCPCD issue.

Comment by Antonio Rojas (arojas) - Monday, 20 April 2020, 06:13 GMT

Please test 9.0.1-3

@insanemal the NM issue is a different one, and unlikely to be fixed anytime soon: https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/410

Comment by Mal Haak (insanemal) - Monday, 20 April 2020, 08:06 GMT

Ahhh thanks for that.

Sorry for that.

Comment by John Barks (Zod) - Monday, 20 April 2020, 13:31 GMT

Installed 9.0.1-3 and rebooted
No Ip Address

Downgraded to 9.0.1-2 and rebooted
No IP Address

Downgraded to 8.1.7-1 and rebooted
Got an IP address and name resolution

Comment by Antonio Rojas (arojas) - Monday, 20 April 2020, 16:07 GMT

Should be fixed in 9.0.1-4, please confirm

Comment by John Barks (Zod) - Monday, 20 April 2020, 16:23 GMT

That fixes it.

I'm good to go, this ticket can be closed as far as I am concerned.

Comment by Milian Wolff (milianw) - Wednesday, 22 April 2020, 21:30 GMT

I'm still seeing errors with 9.0.2, it looks like the permissions on the folder aren't properly fixed?

As I said above, Networkmanager problems are a different issue altogether, and the dhcpcd plugin has been disabled in the latest release
