Redhat System ADSL Configuration Guide

In this paper, we use the method of watching and command-line prompts to explain the detailed process of using ADSL dial-up Internet in red Hat from the angle of installation instance, in the hope that we can help friends who are encountering this difficulty.

You should first determine if you have a PPPoE application installed. If you do already have it installed, you can start the ADSL configuration with the Adsl-setup command at the terminal, prompting the process to be English. The approximate:

[Root@localhost root]# Adsl-setup

Welcome to the ADSL client setup. I'll run some checks on

Your system to make sure the PPPoE client is installed properly ...

The following DSL config is found on your system:

Device:name:

Ppp0 DSLppp0

Please enter the device if your want to configure the present DSL Config

(default ppp0) or enter ' n ' If you want to create a new ONE:PPP0//defaults to PPP0

LOGIN NAME

Enter your Login name (default sj00411210a1): Anthrax//Here replace my anthrax with your own username:)

INTERFACE

Enter the Ethernet interface connected to the ADSL modem

For Solaris, this are likely to be something LIKE/DEV/HME0.

For Linux, it'll be ethx and where ' X ' is a number.

(default eth0): eth0//Defaults network card device is eth0

Do you want the "link to come up" demand, or stay up continuously? If you are want it to come up on demand, enter the idle time into seconds after which the link should be dropped. If you are want the link to stay up permanently, enter ' no ' (two letters, lower-case.)

Note:demand-activated links do not interact-with dynamic IP addresses. Have some problems with demand-activated links.

Enter the demand value (default NO): no//It is OK to use the defaults here, no automatic dialing after disconnection.

Dns

Please enter the IP address of your ISP ' s primary DNS server. If your ISP claims that ' the server'll provide dynamic DNS addresses ', enter ' server ' (all lower-case) here. If you just press ENTER, I'll assume you know what to are doing and not modify DNS setup. Enter The DNS information here:202.96.134.133//Primary DNS address setting, which is replaced by your specific situation.

Please enter the IP address of your ISP ' s secondary DNS server.

If you just press ENTER, I'll assume there is only one DNS server.

Enter the secondary DNS server address here:202.96.134.133//second DNS addresses setting.

PASSWORD

Please enter your Password://Here Set the password, like the UNIX rule, the password does not echo, so don't think your keyboard is out of order:

Please re-enter your Password:

Confirm Password

Userctrl

Please enter ' Yes ' (two letters, lower-case.) If your want to allow normal user to start or stop DSL connection (default Ye s): Yes//whether to allow ordinary users to share ADSL.

Firewalling

Please choose the firewall rules to use. Note this these rules are very basic. You are are strongly encouraged to use a more sophisticated firewall setup; However, these are provide basic security. If you are are running any servers on your machine, you are must choose ' NONE ' and set up firewalling yourself. Otherwise, the firewall rules would deny access to all standard servers like Web, e-mail, FTP, etc. If you are using SSH, the rules would block outgoing SSH connections which allocate a privileged source port.

The firewall choices are:

0-none:this script would not set any firewall rules. You are are responsible for ensuring the security of your machine. You are are strongly recommended to use some kind of firewall rules.

1-standalone:appropriate for a basic stand-alone web-surfing workstation

2-masquerade:appropriate for a machine acting as an Internet gateway for a LAN

Choose a type of firewall (0-2): 1//Configure firewall level, depending on your needs.

Start this connection in boot time

Do you want to start this connection in boot time?

Please enter no or Yes (default NO): no//whether to allow automatic boot load, select No, or the system will start too slow!

Accept These settings and adjust configuration files (y/n)?

Select y, Configuration complete. You can start with the Adsl-start command, and you can stop with the Adsl-stop command.

For convenience, you can set up an application link on your desktop and command to use Adsl-start. So each time you double-click the shortcut icon can be set up ADSL link, as convenient as in Windows.

OK, let's start your online tour now. (Tip: If you can't link to a network based on the content of this article, try removing the current network card from the system Setup-> network and reconfiguring the ADSL entry.) )
