 |
|
Hi,
I'm still new to Gentoo. After last update I got my network interface renamed and I cannot seem to get networking to start automatically on boot anymore. No idea what I'm doing wrong. My previous interface was enp1s0. Now it's enp2s0. Below are few outputs which I find interresting, but let me know if you need any more information:
| Code: |
rc-update show
bootmisc | boot
consolekit | default
dbus | default
devfs | sysinit
dmesg | sysinit
fsck | boot
hostname | boot
hwclock | boot
keymaps | boot
killprocs | shutdown
local | default
localmount | boot
loopback | boot
modules | boot
mount-ro | shutdown
mtab | boot
net.enp2s0 | 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

Then after doing:
| Code: |
ifconfig enp2s0 up
dhcpcd enp2s0
|
everything works fine. But again - I can't make it start by default on boot.
Thanks for help in advance

mlisicki ... can you post the output of the following:
| Code: | | # awk '!/(^#|^$)/' /etc/rc.conf |
and ...
| Code: | | # ls /etc/runlevels/default/ |
best ... khay |

Here you are. And thanks for the response.
| Code: |
$ awk '!/(^#|^$)/' /etc/rc.conf
rc_shell=/sbin/sulogin
rc_logger="YES"
unicode="YES"
rc_tty_number=12
$ ls /etc/runlevels/default/
consolekit dbus local net.enp2s0 netmount sshd syslog-ng
|
For me it looks like I didn't commit/refresh something. Maybe the answer is obvious? I said I'm a noob in Gentoo yet. I completely restarted the system though. I don't assume I have to recompile the kernel or load any new modules. Maybe after the update something is not loading on boot correctly? Although I don't seem to have any more errors there.
Cheers. |

mlisicki ...
I was looking for where net.enp1s0 might be, as its not set in the default runlevel and there is no symlink to net.lo. From the above it doesn't seem to be anywhere so its a bit of a mystery. Did you perhaps add some {use,need,after} definition to any of the files in /etc/conf.d/?
| Code: | | # grep enp1s0 /etc/conf.d/* |
I'm really not sure where this is coming from, is your system clock correct? You might try the following:
| Code: | | # rc-update --update |
You could also explicitly state that net.enp1s0 doesn't provide 'net' ... but this doesn't really tell us why netmount expects to start it and not net.enp2s0.
/etc/rc.conf
| Code: | rc_net_enp1s0_provide="!net"
rc_dhcpcd_provide="!net" |
If neither of these provides a solution then please post /var/log/rc.log and any relevant sections from dmseg.
best ... khay |

netmount no more provides nfs, this is provide by nfsmount.
netmount still provides network, but even correct, i'm not sure any samba shares should be default state as "network" in a linux env. For me network would more fit nfs.
Perhaps you were saying "network" to tell us "nfs" shares are no more mount?
Might also disable new name scheme, as it fail for you (wow i was thinking that thing never fail !) ; because for whatever reason name was change, it mean it might change again soon or later.
rc_need="net.enp2s0" should also be change to rc_need="net" in order to prevent next name change failure.
And i share khayyam suspicion that net.enp1s0 was add into some use,need,after config files. Maybe instead of changing it to enp2s0 better change it to net also, so anyone providing net will run instead to wait for a specific interface. |

| Wow. I would never expect this to be a solution. The same day I did my update I was also changing some hardware in my machine and I had a reason to restart the bios. After that I didn't care so far to adjust the clock there. Doing that solved all the issues. Thanks a lot Khay! (and everyone esle trying to help). |

Wow, good catch guys!
I didn't realise an incorrect RTC could break the network card init... how does that even happen!?  |

Cyker ... because openrc keeps a dependency tree cache, if a file in /etc/init.d/ is newer than the clock then the cache is askew.
