教你在Fedora8下撥號上網

←手機掃碼閱讀     火星人 @ 2014-03-25 , reply:0

Fedora8發布,我早早地將它下載安裝。大的風格沒有明顯地變化,但是感覺到啟動速度快樂很多,這也許是gnome-2.20做了許多改進吧。多謝開發組的大拿了。現在最重要的事情是要上網,所以趕快配置Fedora上網。

在fedora下,使用撥號上網是一件比較麻煩的事情,不過如果你願意手動配置的話,這些也不是一件特別麻煩的事情。下面是我在Fedora 7/8 都嘗試過的方法,比較方便。因為Fedora提供了配置工具來設置撥號上網的參數。我們這裡要使用的工具是pppoe-setup, pppoe-connect, pppoe-stop.

但是在使用上述工具你必須具備超級用戶的許可權,否則是無法完成本文介紹的方法。

pppoe-setup: 設置撥號參數,使用一次足矣(假設你比較幸運的話)

pppoe-connect: 每次撥號時運行此工具,既可以完成撥號上網

pppoe-stop: 每次斷網時,可以運行此工具,拆除同網路供應商的連接。

在本文中,綠色的部分均為手動輸入的內容。

首先,使自己成為根用戶。

[work@localhost ~]$ su

Password:

然後運行pppoe-setu命令。該命令位於/sbin/ (在/usr/sbin/ 下面也有一個同樣的命令,這是一個符號連接到/sbin/的同名)

[root@localhost work]# /sbin/pppoe-setup

然後你會看到pppoe-setup會輸出如下的提示。

Welcome to the PPPoE client setup. First, I will run some checks on

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

LOGIN NAME

現在它提示你輸入你在ISP所用的用戶名(也叫做帳號)。

Enter your Login Name (default work): 1002999

然後你會看到如下提示,這時他會提示你輸入使用連接的乙太網介面,不需要輸入任何內容,默認值即可。

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):

現在系統要求詢問你是否希望在沒有聯網的情況下,系統是否在空閑一段時間后,自動切斷同網路的連接。我不喜歡這樣,我希望在不用的時候,自己手動斷掉連接。於是選擇默認值,直接輸入回車。

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):

接下來,要求你輸入如何設置DNS參數,我選擇的是輸入:server。

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

現在,要求你輸入對應於帳戶的密碼(這有些類似於你在銀行帳戶的密碼一樣,這些參數可以從你的互聯網服務提供商得到),系統會讓你輸入兩次密碼確認。

PASSWORD

Please enter your Password: xxxxxx

Please re-enter your Password: xxxxxx

對於下面的提問,你可以不予理會,使用系統的默認參數即可。

USERCTRL

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

normal user to start or stop DSL connection (default yes):


下面要求你輸入防火牆的選擇,我選擇了沒有使用防火牆。

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

現在它要求你確定是否在系統啟動時自動去撥號,一般來講,這是一種浪費,所以我們選擇輸入默認值,直接輸入回車即可

Start this connection at boot time

Do you want to start this connection at boot time?

Please enter no or yes (default no):

現在,系統開始總結你設置的參數。要求你確認,此時,你可以輸入一個小y來確認。

** Summary of what you entered **

Ethernet Interface: eth0

User name: *sunzhou_110

Activate-on-demand: No

DNS addresses: Supplied by ISP's server

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)

好了,當你看到這句話表明你的參數設置結束了。

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.

但是,此時你還無法聯網,你必須手動建立連接, 此時需要運行pppoe-connect命令。如果你看到了下面的綠色輸出表明你可以在網上衝浪了。 :)

[root@localhost work]# /sbin/pppoe-connect

/sbin/pppoe-connect: line 285: ip: command not found

/sbin/pppoe-connect: line 357: ip: command not found

Using interface ppp0

Connect: ppp0 <--> /dev/pts/1

Remote message: Authentication success,Welcome!

PAP authentication succeeded

local IP address 222.62.108.148

remote IP address 222.62.104.1

primary DNS address 211.98.2.4

secondary DNS address 61.233.9.9

此時你可以運行下面的命令,如果看到域名被正確解析且有回應,則一切OK

[work@localhost ~]$ ping www.kernel.org

PING pub.kernel.org (204.152.191.37) 56(84) bytes of data.

64 bytes from pub2.kernel.org (204.152.191.37): icmp_seq=1 ttl=48 time=311 ms

64 bytes from pub2.kernel.org (204.152.191.37): icmp_seq=2 ttl=48 time=318 ms

64 bytes from pub2.kernel.org (204.152.191.37): icmp_seq=3 ttl=48 time=327 ms

最後,如果在網上玩夠了,則需要斷掉連接,可以運行下面的命令

[root@localhost ~]# /sbin/pppoe-stop

Terminating on signal 15

Connect time 0.6 minutes.

Sent 2558 bytes, received 2166 bytes.

cat: /var/run/pppoe-adsl.pid.start: No such file or directory

pppoe: read (asyncReadFromPPP): Session 5001: Input/output error

如果你看到了最後一行的錯誤報告,不予理會它。怎麼樣,在Fedora上進行網上衝浪也不是這麼麻煩吧。
