*Solved*

Hello,

I am installing Gentoo (Kernel 3.8.13 64bit) on a laptop and I am attempting to use the NetworkManager app to manage interfaces.

The problem is that when I set up NetworkManager I have the following problems:

#1. Network Manager Starts but is Inactive; it never gets the IP on initial start.

Here is my log of the OpenRC startup process. As you can see, when it starts it is marked as inactive. If I use DHCPCD, however, I get the IP right away. Not sure why there is a delay of any kind.

#2. Network Manager eventually forks over to DHCPCD and gets an IP. However, for some reason it discards the IP and then marks the interface as inactive/disconnected

Here is the relevant log from Syslog showing what happens.

I see that NetworkManager seeks an IPV6 address but never finds it. Shouldn't the script/process keep the IPv4 address and just get a link-local IPv6 address?

So, in short, what do I need to do to get NetworkManager to work as it should?

Here is other information that might be relevant:

/etc/conf.d/net

Kernel Config

Dmesg

IFConfig

Let me know what else I can provide.

Thank you in advance for your time.

dhcpcd | * Starting DHCP Client Daemon ... FAIL....

Code:

sudo rc-update delete dhcpcd default


post the results of "rc-update" its much cleaner than that and says what run level your processes start at.

also make sure you have no net.eth0 or net.wlan0 starting...

i also do not have wpa_supplicant starting.... id remove that too

I made the change, here is the result.

I will restart and see what the status is.

OK, this was it! I had no idea you needed to have DHCPCD disabled as well.

These services must have been competing with each other. Everything works as expected now.

Thank you for the help.

id purge the wpa_supplicant if thats still there.... (now i know im correct in saying what level to delete it from...)

Code:

rc-update delete wpa_supplicant default


/etc/mtab -> /proc/self/mounts

is a symlink on my system from systemd requiring it that way.... network manager was a good choice for me as it makes boot time quite a bit quicker... i do use openrc on this laptop as some of the systemd unit files are not ready for production. i should test if removing the mtab updates works as i get messages saying "mtab is a symlink: skipping" this is a note to myself, as im in the middle of updating tons of stuff and i know my booting is broken right now....... plz dont test on ur own might break system... do the wpa part only

removing mtab updates so far so good at 1 test reboot....
