下面就我在linux(在centOS4.4,rhel as 4,fc5下測試通過)下如何通過adsl拔號與共享上網作一個簡單的記錄,希望對新手有所幫助.
1、拔號上網 1.1拔號軟體 linux下的拔號軟體很多,但比較好的是rp-pppoe,一般linux系統會自帶拔號軟體,如果你沒裝,請自己到google去找一個來裝上. 1.2拔號設置 切換為root用戶,只有root才能配置. $ su Password: # /sbin/adsl-setup 按提示設置用戶名、密碼、DNS、及其它相關信息,下面是我的參考配置: Welcome to the ADSL client setup. First, I will run some checks on your system to make sure the PPPoE client is installed properly...
The following DSL config was found on your system:
Device: Name: ppp0 DSLppp0
Please enter the device if you want to configure the present DSL config (default ppp0) or enter 'n' if you want to create a new one:
LOGIN NAME
Enter your Login Name (default xyn0699647):
INTERFACE
Enter the Ethernet interface connected to the ADSL modem For Solaris, this is likely to be something like /dev/hme0. For Linux, it will be ethX, where 'X' is a number. (default eth0):
Do you want the link to come up on demand, or stay up continuously? If you want it to come up on demand, enter the idle time in seconds after which the link should be dropped. If you want the link to stay up permanently, enter 'no' (two letters, lower-case.) NOTE: Demand-activated links do not interact well with dynamic IP addresses. You may have some problems with demand-activated links. Enter the demand value (default no):
DNS
Please enter the IP address of your ISP's primary DNS server. If your ISP claims that 'the server will provide dynamic DNS addresses', enter 'server' (all lower-case) here. If you just press enter, I will assume you know what you are doing and not modify your DNS setup. Enter the DNS information here:
PASSWORD
Please enter your Password: Please re-enter your Password:
USERCTRL
Please enter 'yes' (two letters, lower-case.) if you want to allow normal user to start or stop DSL connection (default yes):
FIREWALLING
Please choose the firewall rules to use. Note that these rules are very basic. You are strongly encouraged to use a more sophisticated firewall setup; however, these will provide basic security. If you are running any servers on your machine, you must choose 'NONE' and set up firewalling yourself. Otherwise, the firewall rules will deny access to all standard servers like Web, e-mail, ftp, etc. If you are using SSH, the rules will block outgoing SSH connections which allocate a privileged source port.
The firewall choices are: 0 - NONE: This script will not set any firewall rules. You are responsible for ensuring the security of your machine. You 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): Please enter a number from 0 to 2 The firewall choices are: 0 - NONE: This script will not set any firewall rules. You are responsible for ensuring the security of your machine. You 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): 0
Start this connection at boot time
Do you want to start this connection at boot time? Please enter no or yes (default no):
** Summary of what you entered **
Ethernet Interface: eth0 User name: xyn0699647 Activate-on-demand: No DNS: Do not adjust Firewalling: NONE User Control: yes Accept these settings and adjust configuration files (y/n)? y Adjusting /etc/sysconfig/network-scripts/ifcfg-ppp0 Adjusting /etc/ppp/chap-secrets and /etc/ppp/pap-secrets (But first backing it up to /etc/ppp/chap-secrets.bak) (But first backing it up to /etc/ppp/pap-secrets.bak)
Congratulations, it should be all set up!
Type '/sbin/ifup ppp0' to bring up your xDSL link and '/sbin/ifdown ppp0' to bring it down. Type '/sbin/adsl-status /etc/sysconfig/network-scripts/ifcfg-ppp0' to see the link status.
