Hi, I struggled long to migrate fully from initd to systemd. Now before I do the step from 12.3 to 13.2, i have concerns of ifup being replaced. Not much answers found googling around. A. can ifup be used instead of wicked B. is migration easy? following setup (IPv4 only): 2 physical network cards (RTL8111/8168) eth0: LAN (DHCPd running on the machine) eth1: (static ip) as connection to VDSL2 modem dsl0: PPPoE dial-up device lo tun0: openvpn server running tun1: vpnc connection (manually created on demand using vpnc) isdn0: backup ISDN dial-in connection (started manually) modem0: backup UMTS dial-in connection (started manually) C. firewall configuration I adjusted SuSEfirewall2 configuration a lot (routing,masquerading,forwarding,...) and added custom scripts for traffic shaping using tc and iptables. have i take care of anything regarding this? Thank's a lot in advance for any info/hints. It is very hard to find information about, especially point C.

How is it related to systemd?

As far as I know - not officially. You may be able to removed wicked and install sysconfig back, but I did not look how difficult it is (I use NM).

...

B. is migration easy? following setup (IPv4 only): 2 physical network cards (RTL8111/8168) eth0: LAN (DHCPd running on the machine) eth1: (static ip) as connection to VDSL2 modem dsl0: PPPoE dial-up device lo tun0: openvpn server running

That may be a problem, someone recently posted that tunX interfaces were not activated by wicked on startup.

...

tun1: vpnc connection (manually created on demand using vpnc) isdn0: backup ISDN dial-in connection (started manually) modem0: backup UMTS dial-in connection (started manually) C. firewall configuration I adjusted SuSEfirewall2 configuration a lot (routing,masquerading,forwarding,...) and added custom scripts for traffic shaping using tc and iptables. have i take care of anything regarding this?

I believe that firewall does not depend on underlying networking implementation, but I may be wrong here.

...

How is it related to systemd? No relation, just mentioned I have concerns doing such "big steps".

do you mean http://lists.opensuse.org/opensuse-factory/2014-11/msg00207.html luckily that doesn't seem to be unsolvable.

I believe that firewall does not depend on underlying networking implementation, but I may be wrong here. I read opensuse uses a wicked extension as firewall. Maybe i should build up a test machine. but hard to test the corresponding scenarios on a different machine.

Thanks Paul

You don't need to use bizarro NIC names like enp5s0 if you don't want. IOW, if you want eth0 & eth1, use net.ifnames=0 on your kernel cmdline or /etc/udev/rules.d/80-net-setup-link.rules or one of the other avoidance configs from the bottom of http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterface...

Personally, I like the bizarro rules. (There's always SOMEBODY ;-) Gotten use to them with openbsd, and they aren't as bizarro as they first seem. You can just look at the nic to know which name its using and know which cable goes there.

Even if I look directly at the port and it is numbered, I am unable to work out which bizarro name it is likely to have.

Well I guess that's what permanent markers were invented for. Regardless of name scheme chosen, you don't want to be opening the case, to check chip-set. So I do that once, get out pen, done. At least we only have a few fake (software) adaptors to ignore.

Oh? Maybe you can "just look" if the machine is freestanding, the end(s) of the cable(s) is/are visible, and/or the cover is easily opened, but many are not so when the need or desire arises. -- "The wise are known for their understanding, and pleasant words are persuasive."

You don't need to use bizarro NIC names like enp5s0 if you don't want.

Personally, I like the bizarro rules. (There's always SOMEBODY ;-)

Gotten use to them with openbsd, and they aren't as bizarro as they first seem. You can just look at the nic to know which name its using and know which cable goes there.

That said, I can't remember how I ended up with old-school names on my fresh install of 13.2 laptop, but I did, and didn't bother to change it.

Add net.ifnames=0 to your grub configuation

Could you give example (especially of "which cable goes there")?

Even if I look directly at the port and it is numbered, I am unable to work out which bizarro name it is likely to have.

If your system supports returning slot names, you should get sX for them. As long as you trust vendor to implement it correctly :)

...

Except for desktops and laptops (which both typically have only one interface), I always rename to ethX.

One reason for inventing new names was avoiding name clash with automatic kernel assignment. This still applies. If you do not like "predictable" names (I do not) use something like netXX. But do not use ethXX, as it puts you back on square one. The only case when it is sure to work is when your names are the same as autossigned by kernels, in which case you can simply leave it to kernel in the first place. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
