I'm working on the cleanup when my time permits ... a lot of this time goes into bug reports that aren't any. (In reply to comment #0)

hi suse developers ..
sorry for bothering you again with network scripts but .. eh.
suse network scripts are unclear, complicated and works badly in 11.2 .. there are many issues like bad invoking dhcpcd via /sbin/ifup-dhcp which leads to preserving dhcpcds' own resolv.conf and so ..
issues are for example:
1) dhcp client survives after carrier removal, iface has address as is up
Change from "At Boot Time" to "On Cable Connection" in yast2 network or manually set STARTMODE="ifplugd" in the ifcfg files. When you have multiple interfaces as wireless and wired, then set also IFPLUGD_PRIORITY, using higher number for the preferred link and lower number to the another, e.g.: 10 for wireless and 20 for wired ethernet; it will cause that wired link is used when carrier is there, otherwise wireless.
2) etc/resolv.conf is preserverd using strange way, so you need to manually kill dhcpcd (dhcpcd -x $iface) and run it again after carrier removal a plug in again
This is not needed in above case, when ifplugd is used. You also don't need to kill dhcpcd manually. Calling the ifdown-dhcp script directly should do it for you. Also "rcnetwork restart eth0".
3) dhcp client is invoked for all iface at startup even if there is no link
In STARTMODE=onboot (auto), yes. See above. You can set STARTMODE=ifplugd.
4) rc scripts produces errors while waiting for *mandatory devices
See above. You can also disable / change this: adjust MANDATORY_DEVICES and/or the WAIT_FOR_INTERFACES variables in network/config.
5) at least ipv6 on/off switch in yast doesn't work ..
Different problem => yast2 network. See bug 558020 - disable ipv6 in YaST2. It is also the only true problem that I see here. 1...4 are caused by the configuration / missed link monitoring. It would be also possible to enable the ifplugd on ethernet interfaces by default (in some cases it is enabled by default, except when the interface is used as bridge port? only when a wireless interface is there/configured?). Feel free to open an enhancement request bug or fate for yast2-network on 11.3. I reassign to the yast2-network maintainer, because of disable_ipv6. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
