Package: network-manager Version: 0.9.4.0-10 Severity: normal Tags: ipv6 Dear Maintainer,
These lines appear in /var/log/syslog every 5 min May 12 07:52:11 sleipnir NetworkManager[6719]: <info> Policy set 'Wired connection 1' (eth0) as default for IPv4 routing and DNS. May 12 07:52:11 sleipnir NetworkManager[6719]: <info> Policy set 'Wired connection 1' (eth0) as default for IPv6 routing and DNS. When it happens, eth0 gets another IPV6 address, for example: eth0 Link encap:Ethernet HWaddr 00:0a:95:66:9c:38 inet addr:192.168.8.14 Bcast:192.168.8.255 Mask:255.255.255.0 inet6 addr: 2002:XXXX:61ef:1:c20:268e:2d67:67a8/64 Scope:Global inet6 addr: 2002:XXXX:61ef:1:188b:efac:7164:7dd8/64 Scope:Global inet6 addr: 2002:XXXX:61ef:1:569:ac30:a77e:7b90/64 Scope:Global inet6 addr: 2002:XXXX:61ef:1:503b:ffd9:1adc:c27c/64 Scope:Global inet6 addr: 2002:XXXX:61ef:1:20a:95ff:fe66:9c38/64 Scope:Global inet6 addr: fe80::20a:95ff:fe66:9c38/64 Scope:Link inet6 addr: 2002:XXXX:61ef:1:5441:2c23:a00b:cdd8/64 Scope:Global UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:24328 errors:0 dropped:0 overruns:0 frame:0 TX packets:20851 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3793711 (3.6 MiB) TX bytes:5166528 (4.9 MiB) Interrupt:41 Base address:0x4800 This system was installed a few weeks ago. I believe I have made no network configuration whatsoever - just relying on standrad DHCP for IPv4 and Autoconfigure for IPv6. I have one other Debain 7.5 system (an armv5tel system, not a PowerPC) on the network, without this problem. I have a very simple 6to4-configured OpenWRT router that advertises the IPV6 network. The clients autoconfigure. I also have several other computers with different operating systems (Xubuntu, Mac OS X, Windows 7) on the network - none of them have problems with several IPV6 addresses. I noticed this problem because the avahi-deamon consumed 99% cpu when I had almost 200 IPv6 addresses: /var/log/syslog: (almost 200 lines like the next line) May 11 07:44:28 sleipnir avahi-daemon[2350]: Withdrawing address record for 2002:XXXX:61ef:1:90d1:46d6:3b17:5f0a on eth0. (then) May 11 07:44:28 sleipnir rsyslogd-2177: imuxsock begins to drop messages from pid 2350 due to rate-limiting May 11 07:44:45 sleipnir NetworkManager[2174]: <warn> error monitoring device for netlink events: No buffer space available May 11 07:44:45 sleipnir minissdpd[3915]: recvmsg(s, &hdr, 0): No buffer space available I understand I may be better off without the avahi-daemon, but switching it off does not fix the problem. Restarting Network Manager brings me down to TWO IPV6-addresses (which is one too much, as I understand it): root@sleipnir:~# service network-manager restart ; /sbin/ifconfig [ ok ] Stopping network connection manager: NetworkManager. [ ok ] Starting network connection manager: NetworkManager. eth0 Link encap:Ethernet HWaddr 00:0a:95:66:9c:38 inet addr:192.168.8.14 Bcast:192.168.8.255 Mask:255.255.255.0 inet6 addr: 2002:XXXX:61ef:1:20a:95ff:fe66:9c38/64 Scope:Global inet6 addr: fe80::20a:95ff:fe66:9c38/64 Scope:Link inet6 addr: 2002:XXXX:61ef:1:8431:f293:326a:4e5/64 Scope:Global UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:35676 errors:0 dropped:0 overruns:0 frame:0 TX packets:28823 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:5006172 (4.7 MiB) TX bytes:6793477 (6.4 MiB) Interrupt:41 Base address:0x4800 According to syslog the problem appeared for the first time on 2014-05-09. According to /etc/apt/history.log the system had not been updated since 2014-05-01. I updated it as soon as I found the problem, but with no success. I belive the problem with TWO addresses has been present since I installed the system. At that time I just found it peculiar. But getting more and more addresses with time is new since May 9. This is an Apple PowerBook. The wireless network (eth1) is disabled. The computer is on 24/7, acting as a test webserver. Workaround: add to /etc/crontab 59 * * * * root service network-manager restart Restarting the computer also takes me down to two addresses, but does not solve the problem. Below is standard reportbug output, run as root, otherwise I got permission error with: /etc/polkit-1/localauthority/10-vendor.d/org.freedesktop.NetworkManager.pkla I find this all strange enough to file a bug report. Thank you all for making a fantastic job with Debian!
