ADSL device in Linux
Need a normal Linux at least one network card broadband device has been applied, and it has been opened
There are about several ADSL devices in the front market, and they have some subtle differences in the way.
This process of completing the Internet through virtual dialing, that is, using the PPPoE device for virtual dialing.
It is called a full-time cat, which is an automatic dialing work after power-on, then left to our interface is RJ45.
The gateway that is generally left to our Dalian area is 10.0.0.2, which is the easiest to deal with it, and finally directly distribute
Give the user a fixed IP, relatively easy to deal with
1. The first need is required to dial:
These devices communicate with the computer via the ETH interface, so the connection of the hardware device is first, especially
It is a broadband cat, must be confirmed correctly (otherwise, don't you do something for a while)
Then start the system, confirm whether the software is installed on the system (check it through rpm -qa | grep pppoe
Find), if there is no installed user, in the disc or go online to Down, after installing, ROOT users
Perform ADSL-SETUP, so that the setting status of the ADSL data is entered, requiring the user name to apply for a broadband.
And some other information, confirm that there is no problem, accept until the end (it is E text, but you can understand,
Simple, about a firewall setting, I usually don't use, choose 0, you can consider it.
After the configuration is complete, execute ADSL-START with root users, which will make ADSL dial-up work, will normal.
Online, if there is any specific problem, let's take a look at the log (/ var / log / messages) telling you what.
Stop ADSL and execute ADSL-STOP (very simple)
2. The other two are easier to deal with:
All-to-a cat: Just set your network card to IP's IP, then the gateway refers to the IP of the full-to-direction cat (10.0.0.2), basically no big problem
Fixed IP: Like a network card configured, you can get IP, gateway, and DNs can be done in filled in the application.
