Bug 186385 – >=net-misc/dhcpcd-3.0.19 netlink: Network is unreachable

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Timo Gurr (RETIRED) 2007-07-23 21:57:00 UTC]

I had to package.mask >=net-misc/dhcpcd-3.0.19 on my rented server since I'm not able to get a working eth0 with that versions.

Let me know if you need more information, also I'm not able to get a static setup working. I tried
config_eth0=( "87.106.14.69 netmask 255.255.255.255 broadcast 87.106.14.69" )
routes_eth0=( "default via 10.255.255.1" )
but no success.

Reproducible: Always

Could you attach wireshark traces for the dhcp transaction from both dhcpcd versions please?

ChangeLog mentions bug 186386.
186386 should be replaced with 186385.
