Hi
I have just installed gentoo on a computer, i used 'genkernel -all' to build the kernel.

To find the name to use for the networks i did 'ifconfig -a':
Code:
 # ifconfig -a
enp1s0: flags=4163<BROADCAST,MULTICAST>  mtu 1500
        ether XX:XX:XX:XX:XX:XX  txqueuelen 1000  (Ethernet)
        RX packets 187  bytes 23866 (23.3 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 79  bytes 11965 (11.6 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
        device interrupt 16  memory 0xfaee0000-faf00000 

enp2s0: flags=4098<BROADCAST,MULTICAST>  mtu 1500
        ether XX:XX:XX:XX:XX:XX  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
        device interrupt 16  memory 0xfafe0000-fb000000 

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1  (Local Loopback)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0


I created a net.enp1s0
Code:
 # ls -l /etc/init.d/net.*
lrwxrwxrwx 1 root root     6 Apr 28 17:55 /etc/init.d/net.enp1s0 -> net.lo
-rwxr-xr-x 1 root root 17415 Apr 21 07:22 /etc/init.d/net.lo

and added it to rc level default:
Code:
 # rc-update
               binfmt | boot                         
             bootmisc | boot                         
               cronie |      default                 
                devfs |                       sysinit
                dmesg |                       sysinit
                 fsck | boot                         
             hostname | boot                         
              hwclock | boot                         
              keymaps | boot                         
            killprocs |              shutdown       
    kmod-static-nodes |                       sysinit
                local |      default                 
           localmount | boot                         
             loopback | boot                         
              modules | boot                         
             mount-ro |              shutdown       
                 mtab | boot                         
           net.enp1s0 |      default                 
             netmount |      default                 
               procfs | boot                         
                 root | boot                         
            savecache |              shutdown       
                 sshd |      default                 
                 swap | boot                         
            swapfiles | boot                         
               sysctl | boot                         
                sysfs |                       sysinit
            syslog-ng |      default                 
         termencoding | boot                         
         tmpfiles.dev |                       sysinit
       tmpfiles.setup | boot                         
                 udev |                       sysinit
              urandom | boot                         


When i reboot the computer, the network is not started,
but when i manually do '/etc/init.d/net.enp1s0 start' the network starts without a problem.
Interestingly, i have yesterday installed gentoo on an identical machine with the same installation cd, and there i did not have this problem.

The log file shows something weird:
Code:
Apr 28 17:32:19 squid_01 syslog-ng[2873]: syslog-ng starting up; version='3.7.2'
Apr 28 17:32:19 squid_01 crond[2901]: (CRON) STARTUP (1.5.0)

Apr 28 17:32:19 squid_01 /etc/init.d/net.eth0[2907]: ERROR: net.eth0 failed to start
Apr 28 17:32:19 squid_01 /etc/init.d/netmount[2995]: ERROR: cannot start netmount as net.eth0 would not start
Apr 28 17:32:19 squid_01 sshd[3019]: Server listening on 0.0.0.0 port 22.
Apr 28 17:32:19 squid_01 sshd[3019]: Server listening on :: port 22.

Why does it want to start net.eth0 (it doesn't even exist, and it is not shown by rc-update), and doesn't try net.enp1s0?

Can anybody help here?

Thank You
Jody

Do you follow guide?

https://wiki.gentoo.org/wiki/Handbook:X86/Full/Networking


But instead of eth0 put enp1s0?

I followed the installation handbook, but what i did can't be all wrong, because i can manually start the network.
But thanks for the link! What is especially interesting is the rc logging - i'll have a look into that.

But i i still don't understand, why my computer wants to start net.eth0...

Sounds like you did some of the recommendations for how to Keep classic 'eth0' naming.
Renaming - if happening - can be seen from dmesg.

charles17 ... that wouldn't explain how a non-existant service is started, and were this the case then that service wouldn't complain "interface eth0 does not exist".

@jody ... I'm hesitent to suggest anything with regard to the current openrc as I'm still using 0.12.4, and having given it some thought I can't think of a reason why your issue would occur. Anyhow, that said, please provide the following:

Code:
# ls -l  /etc/runlevel/default/*
# rc-status --all |tr -s ' '
# mount | grep run

You might try 'rc-update -u' but I'm inclined to think the issue is elsewhere.

best ... khay

@khayyam:
I did a 'rc-update -u' and rebooted: now the network came up as expected.
Thanks!
Jody
