avhai 탐색 서비스 충돌문제.

unity에서 ubuntu 고전으로 갔습니다.
그러니까 인터넷 시작시 avahi 탐색서비스와 충돌을 일으킨다고 하네요.
ms windows7 에서는 무선인터넷이 빠르다가, ubuntu로 갈아탄후 느려지길래
제 컴퓨터가 ubuntu에 최적화가 안되서 그런가 싶었는데 -_-
전에 보니까 avahi와의 충돌이 있었더군요.

전에 다른분이 올려주셨던 해결책 입니다. 우분트 8.04 더군요.

The dreaded eth0:avahi Ubuntu Feisty bug

I have a very simple setup. One wired network card, that's it. No wireless cards at all. Got a brand new machine with a freshly installed Feisty, on Thursday. Worked like a charm, I could surf the Internet with Firefox, and it was fast.

Immediately after the first reboot, the day after, I couldn't access the Internet anymore. My other two machines , who uses the same router/DHCP server, were still working, so I knew it wasn't a network problem. I could ping the router from the Feisty machine, but with packet loss ratios ranging between 40% - 100%. Firefox could not connect to Google or the internal routers webadmin GUI.

Network manager was showing an IP address of 0.0.0.0. If I used System->Administration->Network Tools->Devices, it showed:

* lo
* eth0 (IPv6)
* eth0:avahi (IPv4)

To make a long story short, this is what worked for me, to get it working again:

1. Network manager works best with only the loopback interface specified in the /etc/networking/interfaces file. Comment out lines in /etc/networking/interfaces, leaving only the loopback interface. Make a backup copy first ! I had to use vi, the other editor I tried left invisible characters which messed up the file completely.

sudo cp /etc/network/interfaces /etc/network/interfaces.bak
sudo vi /etc/network/interfaces

Your /etc/network/interfaces should look something like this after the edit:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# This is a list of hotpluggable network interfaces.
# They will be activated automatically by the hotplug subsystem.
# auto eth1

# iface eth1 inet dhcp

2. Next, get a DHCP address for eth1, overriding NetworkManager:

sudo dhclient

3. OK, we now have Internet access again and can use apt-get to reinstall a broken package

sudo apt-get --purge install avahi-autoipd --reinstall

4. Reboot.

After the reboot, Network Manager showed a proper IP address and not 0.0.0.0
I got Internet access back, and things were back to normal.

Using System->Administration->Network Tools->Devices, now showed, after fix:

* lo
* eth0 (IPv4, IPv6)
