Difficult process of configuring Ubuntu9.10AMD64 Network

I suddenly wanted to install Ubuntu9.10AMD64-bit to try something different. After all, I said that the 9.10 startup speed was much faster, but I didn't realize that the speed was fast, but I thought it was slow. So I took the opportunity to download the AMD64 ISO when I got offline. After the network cable is unplugged for the first installation, the DHCP configuration step during the installation process is skipped. After the installation, the system starts a black screen, and the bios self-check fails. The green light of the monitor does not shine. Unmount the device, unplug the hard drive wire, boot the device, and re-plug the device into the BIOS.

Unmount the device, unplug the hard drive wire, boot the device, and re-plug the device into the BIOS.

After you enter the system and configure the network, you cannot automatically obtain the IP address. Add the following according to the solution found on the Internet:

Auto eth0

Iface eth0 inet dhcp

To/etc/network/interfaces, and then restart the network:

Sudo/etc/init. d/networking restart

No effect, even if you restart the machine. The file/etc/resolv. conf cannot be found;

The second installation plug in the network cable, to the DHCP step can not be automatically configured, had to skip;

After the installation, delete network-manager, download the deb of pppoeconf in windows, and install-configuration in ubuntu to connect to the network.

It seems that the network configuration of 9.10 is really a problem, and it has plagued a lot of people. In the past, 9.10 32bit was used well. How can I automatically configure the 64 bit version of DHCP?

Solution to pppoeconf disconnection:

Modify the/etc/pppd/options file and find the location of the following two rows:

Lcp-echo-interval 30

...

Lcp-echo-failure 4

The two lines mean that the system sends an echo request to the ADSL server every 30 seconds to check whether the connection is normal. If the ADSL server does not respond for 120 seconds (30 seconds and seconds), the system will think that there is a problem with the connection and the connection is automatically disconnected.

Change lcp-echo-failure to a larger number:

Lcp-echo-interval 30

...

Lcp-echo-failure 20

It seems that the problem of frequent disconnection can be solved.
