Reproduceable. Forgot to say: it is ifplugd-0.28-alt4 which is in this distro. BTW, this problem doesn't occur in a 4.0 system (Lite 4.0.x): $ rpm -q ifplugd etcnet dhcpcd ifplugd-0.28-alt3 etcnet-0.9.7-alt0.M40.1 dhcpcd-1.3.22pl4-alt3.0 $ but, as I have described in the report, occurs in a 4.1 system (Desktop 4.1): $ rpm -q ifplugd etcnet dhcpcd ifplugd-0.28-alt4 etcnet-0.9.7-alt0.M41.1 dhcpcd-3.0.17-alt4 $ (In reply to comment #2) > BTW, this problem doesn't occur in a 4.0 system (Lite 4.0.x): So, the only significant difference seems to be in dhcpcd. > $ rpm -q ifplugd etcnet dhcpcd > ifplugd-0.28-alt3 > etcnet-0.9.7-alt0.M40.1 > dhcpcd-1.3.22pl4-alt3.0 > $ > > but, as I have described in the report, occurs in a 4.1 system (Desktop 4.1): > > $ rpm -q ifplugd etcnet dhcpcd > ifplugd-0.28-alt4 > etcnet-0.9.7-alt0.M41.1 > dhcpcd-3.0.17-alt4 > $ (In reply to comment #3) > (In reply to comment #2) > > BTW, this problem doesn't occur in a 4.0 system (Lite 4.0.x): > > So, the only significant difference seems to be in dhcpcd.

Perhaps, the newer dhcpcd (> 3.0) should conflict with this version of ifplugd, so that dhcpcd wouldn't be upgraded in a system with the old incompatible ifplugd. And ifplugd should be fixed.

Perhaps, the solution is the solution of https://bugzilla.altlinux.org/show_bug.cgi?id=19582 . Sorry, I'm largely out of that context by now. Just in case, look at ifplugstatus(8) to verify that there's no additional problem with e.g. kernel driver or ifplugd link detection. could you test recent etcnet please ? В 4.1/branch исправления не будут вноситься уже технически (заглушена очередь на сборку), поэтому прошу ошибки, актуальные для sisyphus/p7/t7, перевесить на текущие ветки или сизиф. |
etcnet-0.9.7-alt0.M41.1 dhcpcd-3.0.17-alt4 in Desktop 4.1.1RC 2008/11/15. My default eth0 configuration is to use DHCP and Zeroconf. I booted the computer with the Ethernet cable plugged in, and in the network, there constantly was a running DHCP during the described case. It successfully configured the interface by DHCP, the connection worked. Then I unplugged this computer, and after several hours plugged it back. It didn't bring back the correct configuration. The configuration after re-plugging was missing the DHCP-assigned IP address: # ifconfig eth0 Link encap:Ethernet HWaddr 00:13:A9:91:2A:52 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2929 errors:0 dropped:0 overruns:0 frame:0 TX packets:3053 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2034756 (1.9 MiB) TX bytes:510247 (498.2 KiB) Interrupt:17 eth0:avahi Link encap:Ethernet HWaddr 00:13:A9:91:2A:52 inet addr:169.254.5.91 Bcast:169.254.255.255 Mask:255.255.0.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:17 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:72 errors:0 dropped:0 overruns:0 frame:0 TX packets:72 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:3428 (3.3 KiB) TX bytes:3428 (3.3 KiB) # The relevant logs (excerpts from /var/log/messages): on boot (it did it well): Dec 28 16:36:57 localhost kernel: sky2 eth0: enabling interface Dec 28 16:36:57 localhost kernel: sky2 eth0: Link is up at 100 Mbps, full duplex, flow control both Dec 28 16:36:57 localhost klogd: klogd startup succeeded Dec 28 16:36:57 localhost udevd-final: Handling remaining udev events: succeeded Dec 28 16:36:57 localhost rc: Starting fbsetfont: succeeded Dec 28 16:36:57 localhost /etc/net: ERROR: /etc/net/scripts/ifup-common: No TYPE is specified for iface 'wmaster0' and can't guess automatically.
