CentOS7  连网  拨号上网  PPoe网

 

在安装之前,请确定是否安装  rp-pppoe-3.5.rmp 

如果没有安装,请使用 --replacepkgs  先强制安装它  (CentOS-7-x86_64-Everything-1511.iso 包文件夹内有)

如果没有安装,下面的请不要看了

 

[flx@localhost ~]$ su root # 密码:注意是 root 的密码  如果 是 root 登录,这步免了

 

[root@localhost flx]# pppoe-setup (如果没有安装,会提示未找到命令等的英文提示

Welcome to the PPPoE 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

  ppp1         DSLppp1 

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: aaa

Device 'aaa' is not found in the list, please choose the correct one

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 02802408215): 02802408215 //(输入宽带用户名,也就是那个宽带帐号)

INTERFACE 

Enter the Ethernet interface connected to the PPPoE 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)://(选择网络设备,敲回车,系统默认选择)

 

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): no //(问你是否按需拨号,还是持续连接网络)

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: server//(选择 DNS ,这表示使用 ADSL 拨号会自动获得的 DNS 服务器IP 地址,自动获取就输入 server 吧)

 

PASSWORD

 

Please enter your Password://这里输入宽带密码(当然密码看不见)

Please re-enter your Password://重复输入宽带密码  (密码输入不匹配 就会提示重新输入   Sorry, the passwords do not match.  Try again? (y/n)y  )

 

USERCTRL

 

Please enter 'yes' (three letters, lower-case.) if you want to allow

normal user to start or stop DSL connection (default yes): no    //(是否允许普通用户启动、关闭)

 

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): 0 //(选择 firewall 的规则,我选择 0 ,不使用防火墙 )

 

Start this connection at boot time

 

Do you want to start this connection at boot time?

Please enter no or yes (default no):yes  // (问你是否选择随机启动) 

** Summary of what you entered ** 

Ethernet Interface: eth0

User name:          02802408215

Activate-on-demand: No

DNS addresses:      Supplied by ISP's server

Firewalling:        NONE

User Control:       no

Accept these settings and adjust configuration files (y/n)? y    // (确认一下是否接受设置,如果输入的信息正确 选择 y 重输入这些选择 n)

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/pppoe-status /etc/sysconfig/network-scripts/ifcfg-ppp0'

to see the link status.

 

[root@localhost flx]# pppoe-start

 

 重新启动  这一步很重要  发现能连网了
