这几天【zhè jǐ tiān】不在【bú zài】🐗学校了📮，回家得【huí jiā dé】👯用猫拨号上网【hào shàng wǎng】😜了🧐，在【zài】🐗win7下【xià】🕢面拨号一点问题都💦没有【méi yǒu】，在【zài】🐗Fedora下【xià】🕢，使用拨号上网【hào shàng wǎng】😜就不是那么简🙈单了🧐，下【xià】面是🕋我在【zài】🐗Fedora 14上尝试过的🥇方法【fāng fǎ】（对老版本的🥇fedora也同样奏效），还是比【hái shì bǐ】🍪较方便的🥇。Fedora提供了【tí gòng le】🧐配置工👨具来设【jù lái shè】置拨号上网【hào shàng wǎng】😜的🥇参数🍞。这里要【zhè lǐ yào】使用的【shǐ yòng de】🥇工具有三个【sān gè】：pppoe-setup, pppoe-connect 和 pppoe-stop.

但在使用这些【yòng zhè xiē】工具之🏭前，先把自📹己提升🌄到root权限【quán xiàn】，用su或者su -命令就【mìng lìng jiù】可以【kě yǐ】🚽。

pppoe-setup: 设置拨🗞号参数，使用一【shǐ yòng yī】〰次就行【cì jiù háng】了。

pppoe-connect: 在终端【zài zhōng duān】✋里输入用以拨【yòng yǐ bō】⚓号上网。

pppoe-stop: 很容易【hěn róng yì】🤙理解🐺，这是用来断开【lái duàn kāi】链接的。

首先【shǒu xiān】，使自己⏸成为根用户【yòng hù】😄（root用户【yòng hù】😄）。

[cynicholas@cynicholas ~]$ su
Password:

然后运行pppoe-setup命令。

[root@cynicholas]# pppoe-setup

然后你🕛会看到【huì kàn dào】pppoe-setup会输出如下的🤣提示【tí shì】。

Welcome to the PPPoE client setup. First, I will run some checks on
your system to make sure the PPPoE client is installed properly...

现在【zài】它📠提示你输入你【shū rù nǐ】在【zài】ISP所用的用户名【yòng hù míng】（也叫做🏾帐号,比如我【bǐ rú wǒ】家就是🔇座机号🔼码）。

LOGIN NAME

Enter your Login Name (default work): 051212345678

然后你会看到😴如下提💩示🕣，这时他会提示🕣你输入【nǐ shū rù】使用连接的以【jiē de yǐ】太网接【tài wǎng jiē】口【kǒu】🐳，不需要【bú xū yào】输入任📓何内容，默认值即可。

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):
现在【xiàn zài】系统【xì tǒng】要求询【yào qiú xún】问你是🐰否希望👿在没有联网的情况下，系统【xì tǒng】是否在【shì fǒu zài】🎇空闲一段时间后，自动切【zì dòng qiē】断同网【duàn tóng wǎng】络的连接🦌。我不喜【wǒ bú xǐ】欢这样，我希望在不用【zài bú yòng】🐘的时候，自己手动断掉【dòng duàn diào】📥连接🦌。于是选择默认🍺值🈳，直接输入回车👤。

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):

接下来，要求你🎞输入如【shū rù rú】何设置🔜DNS参数，我选择【wǒ xuǎn zé】😪的是输入【rù】：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

现在【xiàn zài】💭，要求你【yào qiú nǐ】🥦输入对应于帐户的密【hù de mì】码🍒,系统【xì tǒng】会让你🍷输入两次密码🍒确认。

PASSWORD
Please enter your Password: xxxxxx
Please re-enter your Password: xxxxxx

对于下面的提【miàn de tí】问【wèn】，你可【kě】以不予理会【huì】，使用👭系统🤡的默认🍸参数即💰可【kě】。

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【xià miàn yào】求你输入防火【rù fáng huǒ】墙的选🍮择【zé】，我选择【zé】🦅了没有使用防🙋火墙。

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

现在它要求你确定是【què dìng shì】否在【fǒu zài】🚕系统启动时自动去拨号🗺，一般来讲，这是一【zhè shì yī】种浪费💛，所以我【suǒ yǐ wǒ】🕎们选择输入默认值，直接输【zhí jiē shū】🔊入回车【rù huí chē】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):

现在【xiàn zài】，系统开始总【kāi shǐ zǒng】结你设置的参✂数【shù】📀。要求你👓确认，此时，你可以输入一【shū rù yī】个小y来确认🗝。

** 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【hǎo le】😌，当你看🤑到这句【dào zhè jù】话表明【huà biǎo míng】你的参数设置结束了🚉。

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🤯，此时你【cǐ shí nǐ】还无法【hái wú fǎ】🎵联网，你必须手动建立连接，此时需🗿要运行pppoe-connect命令💷。如果你看到了【kàn dào le】类似下面的输【miàn de shū】💑出表明【chū biǎo míng】你可以【nǐ kě yǐ】上网了🎺。

[root@cynicholas ~]# pppoe-connect
RTNETLINK answers: No such process
Using interface ppp0
Connect: ppp0 <--> /dev/pts/2
PAP authentication succeeded
local  IP address 121.228.29.197
remote IP address 218.4.77.56
primary   DNS address 61.177.7.1
secondary DNS address 221.228.255.1

此时你可以运行下面【háng xià miàn】🖖的命令【de mìng lìng】，如果看💺到域名被正确解析且有回应【yǒu huí yīng】🐣，则一切OK

[root@cynicholas ~]# ping www.baidu.com

最后【zuì hòu】，如果需要断掉【yào duàn diào】✏连接👶，可以运【kě yǐ yùn】㊗行下面这个命令：

[root@cynicholas~]# 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

如果你看到了【kàn dào le】最后一行的错🎸误报告🍞，不予理【bú yǔ lǐ】😊会它【huì tā】。

OK,一切大功告成。
