Bug 234389 – dhcp_eth0="release" in /etc/conf.d/net not working

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Pedro Palhoto 2008-08-10 16:01:20 UTC]

In /etc/conf.d/net, dhcp_eth0="release" is not releasing the IP address on /etc/init.d/net.eth0 stop.

Manually doing dhcpcd --release works fine. It is not advised to do it in /etc/conf.d/local.stop as it disables network access before cleanly stopping network services on a reboot/poweroff.

The objective is to maintain the same internal network IP address on a dual-boot machine.

Reproducible: Always



Expected Results:  
I should see a DHCP RELEASE in the router's log when stopping net.eth0.

What version of dhcpcd do you have installed?

[Comment 3 Roy Marples 2008-08-15 20:45:10 UTC]

I don't have a machine with baselayout-1 to test this on anymore, but this works fine for openrc-0.2.5 and dhcpcd-4.0.0_rc5, verified with wireshark.

[Comment 4 Peter Volkov (RETIRED) 2008-09-10 09:48:45 UTC]

Pedro, could you try to install openrc and report back if that works for you?
