[Bug 579941] Re: Upgrade removes eth0 from /etc/network/interfaces
According to a thread in the forum (http://ubuntuforums.org/showthread.php?t=1491242highlight=eth0+network+manager), my disabled networking was probably caused after a hibernate locked up the machine and I had to physically reboot it. Unfortunately, the solution in the thread is for Ubuntu, not KUbuntu which is what I'm running. -- Upgrade removes eth0 from /etc/network/interfaces https://bugs.launchpad.net/bugs/579941 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 579941] Re: Upgrade removes eth0 from /etc/network/interfaces
I read a bit about the current network interface management system and compared my setup with another Lucid install where networking works fine. Ashutosh, you're correct: my /etc/network/interfaces should not contain a line about eth0, Network Manager should pick up the hardware and activate it automatically. So why doesn't it? And, if 'ifup' and /etc/network/interfaces is the old way of doing things, what is the correct way? Here is the output of lshw, when the computer is started without 'eth0' in /etc/network/interfaces: $ sudo lshw -c network *-network DISABLED description: Ethernet interface product: NetLink BCM5789 Gigabit Ethernet PCI Express vendor: Broadcom Corporation physical id: 0 bus info: p...@:02:00.0 logical name: eth0 version: 11 serial: 00:30:1b:b9:70:1c capacity: 1GB/s width: 64 bits clock: 33MHz capabilities: pm vpd msi pciexpress bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion=3.102 duplex=half firmware=5789-v3.29a latency=0 link=yes multicast=yes port=twisted pair resources: irq:18 memory:dfef-dfef Why would it be disabled? After I explicitly activate eth0 with 'ifup', 'lshw network' does not show it as 'DISABLED' any more. What do I need to do to boot up enabled? -- Upgrade removes eth0 from /etc/network/interfaces https://bugs.launchpad.net/bugs/579941 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The network connection (for DHCP) should be either be allowed to automatically get configured through the 'Network Connections GUI' OR by including: auto ethX iface ethX inet dhcp where X is replaced by your preferred network card's number. Not both. -- Upgrade removes eth0 from /etc/network/interfaces https://bugs.launchpad.net/bugs/579941 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 579941] Re: Upgrade removes eth0 from /etc/network/interfaces
Ashutosh, why do you think anything was done through the Network Connections GUI? To be clear: I did a straightforward install from a KUbuntu Lucid CD, formatting my root partition first. Other than picking my timezone and partitions to format, I picked installer's defaults. The network connection then worked fine for over a week, during which I updated the installed packages at least once. Then a few days ago it stopped working. While trying to fix the problem, I realized that /etc/network/interfaces only contained the definition for loopback, and restored my network access by adding eth0 to this file. I didn't try fixing the problem via the GUI, because I didn't know about it. At any rate, something caused my network configuration to be lost, wherever it is defined by default -- in the GUI or /etc/network/interfaces. -- Upgrade removes eth0 from /etc/network/interfaces https://bugs.launchpad.net/bugs/579941 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 579941] Re: Upgrade removes eth0 from /etc/network/interfaces
I had almost the same problem.

[Bug 579941] Re: Upgrade removes eth0 from /etc/network/interfaces
(sorry I pressed post by mistake) 1) Ensure that the /etc/network/interfaces file has no 'auto eth0..' only 'auto lo'. Then create a new connections through 'Edit Connections' and enter the mac address and keep ipv4 to 'Automatic (DHCP)'. At first it didn't work, but later it did. But before that even I edited my interfaces file to add 'auto eth0...'. Connection was done properly but then something was wrong with the network connection panel applet (it did not show no matter what I did). I did what I was told (i.e point 1) and the connection was still proper and the applet was proper. The main point I kept reading was that it is recommended to try connecting using the applet rather than editing the interfaces file. So I thought I would share that. -- Upgrade removes eth0 from /etc/network/interfaces https://bugs.launchpad.net/bugs/579941 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Aha, thank you, I didn't realize that you had the same problem and that going through the GUI was the recommended way. Either way, whatever was done by default worked fine until some package upgrade messed it up. -- Upgrade removes eth0 from /etc/network/interfaces https://bugs.launchpad.net/bugs/579941 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
