Debian network settings: Linux Release Technology-Debian information. For more information, see the following. Some time ago it was a bit boring. We installed debian etch and freebsd through the virtual machine, because the company's computer standard system was win2k, I secretly installed an xp package for customers' business trips. (another reason is that xp can be installed at any time when there is a problem. Unlike a company's customized system, if it breaks down, it would be too troublesome to run it back for installation .) So it can be messed up on xp. Has been addicted to linux and bsd.
Some time ago, we upgraded the debian kernel and found that the Network was abnormal. The content modified by/etc/network/interfaces is invalid. I checked it carefully for a long time. The file was automatically modified by the new kernel. The line auto eth0 is missing.
Available:
# 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
# The primary network interface
# Added support for hot swapping
Allow-hotplug eth0
# Automatically activate the NIC and guess it. Wait for further data verification.
Auto eth0
Iface eth0 inet dhcp
The command to manually modify the ip address and route is as follows:
Ifconfig and route commands can be used to temporarily set IP addresses and gateways:
Ifconfig-a displays network settings
Ifconfig eth0 inet down first disable eth0
Ifconfig eth0 inet up 192.168.1.2 \
Netmask 255.255.255.0 broadcast 192.168.1.255 is a row. Set IP addresses
Route add default gw 192.168.1.1 eth0 set Gateway
If the route del default gw 192.168.1.1 gateway is incorrect, you can delete it. After setting it, you can use route to check
Set the DNS and directly write/etc/resolv. conf. It is okay to write a few more files, but I don't know if it will be used. The following two are Opendns, which is good, especially for users of China Telecom and China Telecom.
