No internet connection after boot

English Network/Internet
1

Hi

System setup:
Clean 12.1 install on brand new disk. Nothing special.
eth0 -> local LAN
eth1 -> to DSL modem (dsl0)
dsl0 -> to internet
All devices are set to STARTMODE=‘auto’ and USERCONTROL=‘no’

After every reboot ifconfig only shows eth0 device. To access the internet I either need to run yast and configure something in DSL or network connection or run “systemctl start network.service”.
I read https://fedoraproject.org/wiki/How_to_debug_Systemd_problems but could not find a solution to my problem. After reboot systemctl list-units -t service --all shows:

Anyone could probably help me finding the issue here?

Well, when your eth1 is not configured after boot, I guess we should have a look at /etc/sysconfig/network and the file* ifcfg-eth1* there. Please post the ooutput of

cat /etc/sysconfig/network/eth*
3

I checked this already. The only differences between ifcfg-eth0 and ifcfg-eth1 are the names an IP addresses. diff ifcfg-eth0 ifcfg-eth1 shows:


4c4
< IPADDR='10.0.0.5/24'
---
> IPADDR='192.168.200.1/24'
6c6
< NAME='MCP77 Ethernet'
---
> NAME='DECchip 21142/43'

The content of ifcfg-eth0 is:

BOOTPROTO='static'
BROADCAST=''
ETHTOOL_OPTIONS=''
IPADDR='10.0.0.5/24'
MTU=''
NAME='MCP77 Ethernet'
NETWORK=''
REMOTE_IPADDR=''
STARTMODE='auto'
USERCONTROL='no'

The content ofifcfg-dsl0 is

BOOTPROTO='none'
DEVICE='eth1'
MODEM_IP='10.0.0.138'
NAME='DSL-Verbindung'
PPPD_OPTIONS=''
PPPMODE='pppoe'
PROVIDER='tonline-dsl'
STARTMODE='auto'
UDI=''
USERCONTROL='no'
VPIVCI=''

The strange thing is that after i type (sometimes i need to do this two times) “systemctl start network.service” everything works. Thus, I suspect that systemd is not aware that eth1 and dsl0 should be started directly.
I also enabled LogLevel=debug and LogTarget=syslog-or-kmsg in /etc/systemd/system.conf but could not see anything strange in /var/log/messages

When I am asked to post the ouput of cat /etc/sysconfig/network/ifcfg-eth*, I post:

boven:~ # cat /etc/sysconfig/network/ifcfg-eth*
BOOTPROTO='static'
BROADCAST=''
ETHTOOL_OPTIONS=''
IPADDR='10.0.0.154/24'
MTU=''
NAME='82801G (ICH7 Family) LAN Controller'
NETWORK=''
REMOTE_IPADDR=''
STARTMODE='auto'
USERCONTROL='no'
boven:~ #

Thus everybody can see what my prompt is (reveal the working directory and the user) that I pasted the required command correct (sometimes people do not copy/paste, but make typos), and the required complete output (which is shown by the new prompt).

I may post other things that I think might be of interest, but I at least would post what is asked for. This may be of minor interest here, but offering something like a diff output instead might hide something crucial. Do not forget you are having a problem. You are allready working on it for some time and you most probably will have looked into many places where you decided “these are of no interest to my problem”. But you did not find it. Others will proably walk another path in getting the information that might help them to find what your problem is. That is good, because often the original debugger walked into some path with a dead end. A refreshing new approach might lead to an Eureka. Please do not hamper other people helping you in not giving them what they ask for (or at least give arguments why you don’t). They might get irritated and go elsewhere without even telling you.

After this small lesson in “how to help people trying to help you”, please relax :wink:

When you have the idea that systemd might be doing this, then use the old sysvinit by pressing F5 when in the boot screen. When this functions to your satisfaction, the following step (but we can discuss that here) could be using sysvinit automaticaly (by-pass) and filing a bug report.

As you wish. Here is the output of cat /etc/sysconfig/network/ifcfg-eth*:


hal:/etc/sysconfig/network # cat /etc/sysconfig/network/ifcfg-eth*

BROADCAST=''
ETHTOOL_OPTIONS=''

Since it does work sometimes, when started manually, I suspect systemd too. Reboot, hit F5 in GRUB, pick Sytem V as the initprogram and let us know what happens.

Reboot, hit F5 in GRUB, pick Sytem V as the initprogram and let us know what happens.

With this, everything works like a charm.

Two things here:

  1. I want this new fancy systemd thing everybody else is so excited about. So I will continue, hopefully with your help, to find a solution to my problem. I don’t think that my system setup is that special.
  2. I don’t want to waste your time. If you just could point me in the right direction to find the error. Something like enable debug here, look at the following … Just something where I can start searching for the problem.

One strange thing that i just found during my different reboots is that sometimes systemd starts dsl0. But it never starts eth1.

When you have the idea that systemd might be doing this, then use the old sysvinit by pressing F5 when in the boot screen. When this functions to your satisfaction, the following step (but we can discuss that here) could be using sysvinit automaticaly (by-pass) and filing a bug report.

I stay to my text: file a bug (documenetd as good as possible). And the cooperate with the people behind the Bugzilla in providing more information if they ask for it. They are the developers and know much better where to look and check the code then we can do.

There are already serveral systemd related bugs e.g. Access Denied Access Denied
