下面这个 /etc/ppp/options
选项文件能够被用来与CISCO终端服务器的
PPP线连接。
crtscts # enable hardware flow control
modem # modem control line
noipdefault # remote PPP server must supply your IP address
# if the remote host does not send your IP during IPCP
# negotiation, remove this option
passive # wait for LCP packets
domain ppp.foo.com # put your domain name here
:remote_ip
# put the IP of remote PPP host here
# it will be used to route packets via PPP link
# if you didn't specified the noipdefault option
# change this line to local_ip
:remote_ip
defaultroute # put this if you want that PPP server will be your
# default router
连接:
使用 Kermit (或其他 modem
程序来拨号), 然后输入您的用户名和口令
(或在远程主机上启用 PPP 所需的其他信息)。
退出 Kermit (并不挂断连接)。
键入下面这行:
#
/usr/sbin/pppd /dev/tty01
19200
一定要使用正确的速度和设备名。
现在您的计算机已经用PPP连接。 如果连接失败,
您可在文件 /etc/ppp/options
中添加
debug
选项, 并查看控制台信息以跟踪问题。
下面这个/etc/ppp/pppup
脚本能自动完成这三个步骤:
#!/bin/sh
pgrep -l pppd
pid=`pgrep pppd`
if [ "X${pid}" != "X" ] ; then
echo 'killing pppd, PID=' ${pid}
kill ${pid}
fi
pgrep -l kermit
pid=`pgrep kermit`
if [ "X${pid}" != "X" ] ; then
echo 'killing kermit, PID=' ${pid}
kill -9 ${pid}
fi
ifconfig ppp0 down
ifconfig ppp0 delete
kermit -y /etc/ppp/kermit.dial
pppd /dev/tty01 19200
/etc/ppp/kermit.dial
是一个 Kermit
脚本, 它会完成拨号, 并在远程主机上完成所有需要的身份验证过程
(这份文档的最后有一个脚本实例)。
使用下面这个脚本/etc/ppp/pppdown
断开PPP连线:
#!/bin/sh
pid=`pgrep pppd`
if [ X${pid} != "X" ] ; then
echo 'killing pppd, PID=' ${pid}
kill -TERM ${pid}
fi
pgrep -l kermit
pid=`pgrep kermit`
if [ "X${pid}" != "X" ] ; then
echo 'killing kermit, PID=' ${pid}
kill -9 ${pid}
fi
/sbin/ifconfig ppp0 down
/sbin/ifconfig ppp0 delete
kermit -y /etc/ppp/kermit.hup
/etc/ppp/ppptest
通过执行/usr/etc/ppp/ppptest
,
看看pppd
是否仍在运行:
#!/bin/sh
pid=`pgrep pppd`
if [ X${pid} != "X" ] ; then
echo 'pppd running: PID=' ${pid-NONE}
else
echo 'No pppd running.'
fi
set -x
netstat -n -I ppp0
ifconfig ppp0
执行脚本
/etc/ppp/kermit.hup
以挂起moderm, 这个文件包含:
set line /dev/tty01 ; put your modem device here
set speed 19200
set file type binary
set file names literal
set win 8
set rec pack 1024
set send pack 1024
set block 3
set term bytesize 8
set command bytesize 8
set flow none
pau 1
out +++
inp 5 OK
out ATH0\13
echo \13
exit
也可以用chat
代替kermit
:
以下两个文件用以建立pppd
连接。
/etc/ppp/options
:
/dev/cuad1 115200
crtscts # enable hardware flow control
modem # modem control line
connect "/usr/bin/chat -f /etc/ppp/login.chat.script"
noipdefault # remote PPP serve must supply your IP address
# if the remote host doesn't send your IP during
# IPCP negotiation, remove this option
passive # wait for LCP packets
domain your.domain
# put your domain name here
: # put the IP of remote PPP host here
# it will be used to route packets via PPP link
# if you didn't specified the noipdefault option
# change this line to local_ip
:remote_ip
defaultroute # put this if you want that PPP server will be
# your default router
/etc/ppp/login.chat.script
:
ABORT BUSY ABORT 'NO CARRIER' "" AT OK ATDTphone.number
CONNECT "" TIMEOUT 10 ogin:-\\r-ogin: login-id
TIMEOUT 5 sword: password
一旦这些被安装且修改正确, 您所要做的就是运行pppd
, 就像这样:
#
pppd
/etc/ppp/options
要包括下面这些内容:
crtscts # Hardware flow control
netmask 255.255.255.0 # netmask (not required)
192.114.208.20:192.114.208.165 # IP's of local and remote hosts
# local ip must be different from one
# you assigned to the Ethernet (or other)
# interface on your machine.
# remote IP is IP address that will be
# assigned to the remote machine
domain ppp.foo.com # your domain
passive # wait for LCP
modem # modem line
下面这个脚本/etc/ppp/pppserv
使pppd以服务器方式启动:
#!/bin/sh
pgrep -l pppd
pid=`pgrep pppd`
if [ "X${pid}" != "X" ] ; then
echo 'killing pppd, PID=' ${pid}
kill ${pid}
fi
pgrep -l kermit
pid=`pgrep kermit`
if [ "X${pid}" != "X" ] ; then
echo 'killing kermit, PID=' ${pid}
kill -9 ${pid}
fi
# reset ppp interface
ifconfig ppp0 down
ifconfig ppp0 delete
# enable autoanswer mode
kermit -y /etc/ppp/kermit.ans
# run ppp
pppd /dev/tty01 19200
使用脚本/etc/ppp/pppservdown
停止服务器:
#!/bin/sh
pgrep -l pppd
pid=`pgrep pppd`
if [ "X${pid}" != "X" ] ; then
echo 'killing pppd, PID=' ${pid}
kill ${pid}
fi
pgrep -l kermit
pid=`pgrep kermit`
if [ "X${pid}" != "X" ] ; then
echo 'killing kermit, PID=' ${pid}
kill -9 ${pid}
fi
ifconfig ppp0 down
ifconfig ppp0 delete
kermit -y /etc/ppp/kermit.noans
下面的 Kermit 脚本
(/etc/ppp/kermit.ans
) 能够启用/禁用您 modem
的自动应答模式。 其内容类似下面这样:
set line /dev/tty01
set speed 19200
set file type binary
set file names literal
set win 8
set rec pack 1024
set send pack 1024
set block 3
set term bytesize 8
set command bytesize 8
set flow none
pau 1
out +++
inp 5 OK
out ATH0\13
inp 5 OK
echo \13
out ATS0=1\13 ; change this to out ATS0=0\13 if you want to disable
; autoanswer mode
inp 5 OK
echo \13
exit
一个名为/etc/ppp/kermit.dial
的脚本用于向远程主机
进行拨号和验证。 您要根据需要定制它。 要加入您的登寻名和密码,
您还要根据 modem 和远程主机的反应修改输入语句。
