Public bug reported: Since few days, when I turn on my laptop (Dell Inspiron 6000), I have eth0 & eth1 active at boot, but only eth0 is used, eth1 is the wifi card, and I don't use it.
So, I do a "sudo ifconfig eth1 down", but less than a minute later, eth1 has woke up. But when I check just after typing the command, eth1 doesn't appears, so she's inactive, and she turns on without any human action. For help, I give you my /etc/network/interfaces, and my ifconfig with eth0 and eth1 up. /etc/network/interfaces : [EMAIL PROTECTED]:/# cat /etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.0.2 netmask 255.255.255.0 gateway 192.168.0.1 #auto eth1 #iface eth1 inet dhcp #auto eth2 #iface eth2 inet dhcp #auto ath0 #iface ath0 inet dhcp #auto wlan0 #iface wlan0 inet dhcp ifconfig with eth0 and eth1 up : [EMAIL PROTECTED]:/etc# ifconfig eth0 Lien encap:Ethernet HWaddr 00:11:43:76:F8:EF inet adr:192.168.0.2 Bcast:192.168.0.255 Masque:255.255.255.0 adr inet6: fe80::211:43ff:fe76:f8ef/64 Scope:Lien UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Packets reçus:16553 erreurs:0 :0 overruns:0 frame:0 TX packets:10968 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:1000 Octets reçus:21587912 (20.5 MiB) Octets transmis:867690 (847.3 KiB) Interruption:201 eth1 Lien encap:Ethernet HWaddr 00:12:F0:41:E2:98 inet adr:192.168.0.31 Bcast:192.168.0.255 Masque:255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 Packets reçus:0 erreurs:0 :0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:1000 Octets reçus:0 (0.0 b) Octets transmis:0 (0.0 b) Interruption:177 Adresse de base:0xe000 Mémoire:dfdfd000-dfdfdfff ** Affects: Ubuntu Importance: Undecided Status: Unconfirmed -- eth1 interface wakes up after sudo ifconfig eth1 down https://launchpad.net/bugs/94713 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
