树莓派pppoe

连接的网络是移动（铁通）的宽带，不同的宽带的dns需要修改。

1.首先安装pppoe包

apt-get install pppoe

2.然后，复制conf文件/etc/ppp/pppoe.conf：

#***********************************************************************

# pppoe.conf

# Configuration file for rp-pppoe. Edit as appropriate and install in
# /etc/ppp/pppoe.conf
#

# pppoe-status shell scripts. It is *not* used in any way by the

# When you configure a variable, DO NOT leave spaces around the "=" sign.

# Ethernet card connected to DSL modem
ETH=‘eth0‘

# PPPoE user name. You may have to supply "@provider.com" Sympatico
# users in Canada do need to include "@sympatico.ca"
# Sympatico uses PAP authentication. Make sure /etc/ppp/pap-secrets
# contains the right username/password combination.
# For Magma, use [email protected]
USER=‘××××××ב

# Bring link up on demand? Default is to leave link up all the time.
# If you want the link to come up on demand, set DEMAND to a number indicating
# the idle time after which the link is brought down.
DEMAND=no
#DEMAND=300

# DNS type: SERVER=obtain from server; SPECIFY=use DNS1 and DNS2;
# NOCHANGE=do not adjust.
DNSTYPE=SPECIFY

# Obtain DNS server addresses from the peer (recent versions of pppd only)
# In old config files, this used to be called USEPEERDNS. Changed to
# PEERDNS for better Red Hat compatibility
PEERDNS=no

DNS2=211.98.4.1

# Make the PPPoE connection your default route. Set to
# DEFAULTROUTE=no if you don‘t want this.
DEFAULTROUTE=yes

### ONLY TOUCH THE FOLLOWING SETTINGS IF YOU‘RE AN EXPERT

# How long pppoe-start waits for a new PPP interface to appear before
# concluding something went wrong. If you use 0, then pppoe-start
# exits immediately with a successful status and does not wait for the
# link to come up. Time is in seconds.
#
# WARNING WARNING WARNING:
#
# If you are using rp-pppoe on a physically-inaccessible host, set
# CONNECT_TIMEOUT to 0. This makes SURE that the machine keeps trying
# to connect forever after pppoe-start is called. Otherwise, it will
# give out after CONNECT_TIMEOUT seconds and will not attempt to
# connect again, making it impossible to reach.
CONNECT_TIMEOUT=30

# How often in seconds pppoe-start polls to check if link is up
CONNECT_POLL=2

# Specific desired AC Name
ACNAME=

# Specific desired service name
SERVICENAME=

# Character to echo at each poll. Use PING="" if you don‘t want
# anything echoed
PING="."

# File where the pppoe-connect script writes its process-ID.
# Three files are actually used:
# $PIDFILE contains PID of pppoe-connect script
# $PIDFILE.pppoe contains PID of pppoe process
# $PIDFILE.pppd contains PID of pppd process
CF_BASE=`basename $CONFIG`
PIDFILE="/var/run/$CF_BASE-pppoe.pid"

# Do you want to use synchronous PPP? "yes" or "no". "yes" is much
# easier on CPU usage, but may not work for you. It is safer to use
# "no", but you may want to experiment with "yes". "yes" is generally
# safe on Linux machines with the n_hdlc line discipline; unsafe on others.
SYNCHRONOUS=no

# Do you want to clamp the MSS? Here‘s how to decide:
# - If you have only a SINGLE computer connected to the DSL modem, choose
# "no".
# - If you have a computer acting as a gateway for a LAN, choose "1412".
# The setting of 1412 is safe for either setup, but uses slightly more
# CPU power.
CLAMPMSS=1412
#CLAMPMSS=no

# LCP echo interval and failure count.
LCP_INTERVAL=20
LCP_FAILURE=3

# PPPOE_TIMEOUT should be about 4*LCP_INTERVAL
PPPOE_TIMEOUT=80

# Firewalling: One of NONE, STANDALONE or MASQUERADE
FIREWALL=NONE

# Linux kernel-mode plugin for pppd. If you want to try the kernel-mode
# plugin, use LINUX_PLUGIN=/etc/ppp/plugins/rp-pppoe.so
LINUX_PLUGIN=

# Any extra arguments to pass to pppoe. Normally, use a blank string
# like this:
PPPOE_EXTRA=""

# Rumour has it that "Citizen‘s Communications" with a 3Com
# HomeConnect DSL Modem DualLink requires these extra options:
# PPPOE_EXTRA="-f 3c12:3c13 -S ISP"

# Any extra arguments to pass to pppd. Normally, use a blank string
# like this:
PPPD_EXTRA=""

########## DON‘T CHANGE BELOW UNLESS YOU KNOW WHAT YOU ARE DOING
# If you wish to COMPLETELY overrride the pppd invocation:
# Example:
# OVERRIDE_PPPD_COMMAND="pppd call dsl"

# If you want pppoe-connect to exit when connection drops:
# RETRY_ON_FAILURE=no

3.接着配置pppoe

[email protected]:/mnt/pi_boot/home# pppoe-setup
Welcome to the Roaring Penguin PPPoE client setup.  First, I will run
some checks on your system to make sure the PPPoE client is installed
properly...

Looks good!  Now, please enter some information:

USER NAME

>>> Enter your PPPoE user name (default username): 用户名

INTERFACE

>>> Enter the Ethernet interface connected to the DSL modem
For Solaris, this is likely to be something like /dev/hme0.
For Linux, it will be ethn, where ‘n‘ 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 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

PASSWORD

>>> Please enter your PPPoE password:密码
>>> Please re-enter your PPPoE password:密码

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): 2

** Summary of what you entered **

Ethernet Interface: eth0
User name:          用户名
Activate-on-demand: No
DNS addresses:      Supplied by ISP‘s server
Firewalling:        MASQUERADE

>>> Accept these settings and adjust configuration files (y/n)? y
Adjusting /etc/ppp/pppoe.conf
Adjusting /etc/ppp/pap-secrets and /etc/ppp/chap-secrets
  (But first backing it up to /etc/ppp/pap-secrets-bak)
  (But first backing it up to /etc/ppp/chap-secrets-bak)

Congratulations, it should be all set up!

Type ‘pppoe-start‘ to bring up your PPPoE link and ‘pppoe-stop‘ to bring
it down.  Type ‘pppoe-status‘ to see the link status.
