一.Linux与Linux之间的互拔:

请看图一:

我家里: 办公室:

机器名:j128 机器名:vms68

OS: RedHat5.1 OS: RedHat5.1

IP: 192.168.88.128 IP: 192.168.89.68

Internet

| [ttyS0] [ttyS1] [ttyS0]

|网线

|

机器名:j003

OS: Win98

IP: 192.168.88.3

第一步要配置Linux为ppp服务器,允许拔入,如姚飞所说:

使用mgetty

(以下假设modem装在ttyS0)

cd /etc

vi inittab

add :

d1:2345:respawn:/sbin/mgetty ttyS0 # COM1口允许拔入

d2:2345:respawn:/sbin/mgetty ttyS1 # COM2口允许拔入

then: init q # 重读配置文件/etc/inittab

注意, 如果想拔号出去, pppd 使用的设备也必须是/dev/ttyS0或/dev/ttyS1,

而不是/dev/modem, 要不然是拨不出去的.

我这样做后,j128和vms68都可允许拔入,但还不是ppp server,还需要以下几步:

在vms68里:

adduser ppp #新加一个用户

passwd ppp #为ppp起个密码

在/home/ppp下建一个脚本ppplogin,内容如下:

exec /usr/sbin/pppd 115200 modem asyncmap 0 proxyarp

192.168.89.68:192.193.89.69

##### LOCALIP:REMOTEIP

vi /etc/passwd

将这行ppp:xxxx:505:505:ppp acount:/home/ppp:/bin/bash

改为ppp:xxxx:505:505:ppp acount:/home/ppp:/home/ppp/ppplogin

在j128里:

adduser ppp #新加一个用户

passwd ppp #为ppp起个密码

在/home/ppp下建一个脚本ppplogin,内容如下:

exec /usr/sbin/pppd 115200 modem asyncmap 0 proxyarp

0.0.0.0:0.0.0.0.0 ###等vms68分配ip地址

vi /etc/passwd

将这行ppp:xxxx:505:505:ppp acount:/home/ppp:/bin/bash

改为ppp:xxxx:505:505:ppp acount:/home/ppp:/home/ppp/ppplogin

下一步要配j128拔到vms68,这很简单,

跟拔到Internet是一样的,文件ppp-onvms68如下:

# Script to initiate a ppp connection. This is the first part of the

# pair of scripts. This is not a secure pair of scripts as the codes

# are visible with the 'ps' command. However, it is simple.

#

# These are the parameters. Change as needed.

TELEPHONE=xxxx # The telephone number for the connection

ACCOUNT=ppp # The account name for logon (as in 'George Burns')

PASSWORD=xxxx # The password for this account (and 'Gracie Allen')

LOCAL_IP=0.0.0.0 # Local IP address if known. Dynamic = 0.0.0.0

REMOTE_IP=0.0.0.0 # Remote IP address if desired. Normally 0.0.0.0

NETMASK=255.255.255.0 # The proper netmask if needed

#

# Export them so that they will be available at 'ppp-on-dialer' time.

export TELEPHONE ACCOUNT PASSWORD

#

# This is the location of the script which dials the phone and logs

# in. Please use the absolute file name as the $PATH variable is not

# used on the connect option. (To do so on a 'root' account would be

# a security hole so don't ask.)

#

DIALER_SCRIPT=/home/ppp/ppp-on-dialer

#

# Initiate the connection

#

# I put most of the common options on this command. Please, don't

# forget the 'lock' option or some programs such as mgetty will not

# work. The asyncmap and escape will permit the PPP link to work with

# a telnet or rlogin connection. You are welcome to make any changes

# as desired. Don't use the 'defaultroute' option if you currently

# have a default route to an ethernet gateway.

#

exec /usr/sbin/pppd /dev/ttyS0 115200 modem $LOCAL_IP:$REMOTE_IP

defaultroute lock crtscts asyncmap 0 connect $DIALER_SCRIPT

debug

现在配vms68拔到j128,文件ppp-onj128如下:

# Script to initiate a ppp connection. This is the first part of the

# pair of scripts. This is not a secure pair of scripts as the codes

# are visible with the 'ps' command. However, it is simple.

#

# These are the parameters. Change as needed.

TELEPHONE=xxxx # The telephone number for the connection

ACCOUNT=ppp # The account name for logon (as in 'George Burns')

PASSWORD=xxxx # The password for this account (and 'Gracie Allen')

LOCAL_IP=192.168.89.68 # Local IP address if known. Dynamic = 0.0.0.0

REMOTE_IP=192.168.89.69 # Remote IP address if desired. Normally 0.0.0.0

NETMASK=255.255.255.0 # The proper netmask if needed

#

# Export them so that they will be available at 'ppp-on-dialer' time.

export TELEPHONE ACCOUNT PASSWORD

#

# This is the location of the script which dials the phone and logs

# in. Please use the absolute file name as the $PATH variable is not

# used on the connect option. (To do so on a 'root' account would be

# a security hole so don't ask.)

#

DIALER_SCRIPT=/home/ppp/ppp-on-dialer

#

# Initiate the connection

#

# I put most of the common options on this command. Please, don't

# forget the 'lock' option or some programs such as mgetty will not

# work. The asyncmap and escape will permit the PPP link to work with

# a telnet or rlogin connection. You are welcome to make any changes

# as desired. Don't use the 'defaultroute' option if you currently

# have a default route to an ethernet gateway.

#

exec /usr/sbin/pppd /dev/ttyS1 115200 modem $LOCAL_IP:$REMOTE_IP

lock crtscts asyncmap 0 connect $DIALER_SCRIPT

debug

这里要注意LOCAL_IP和REMOTE_IP要给值,还有的是在pppd里没有defaultroute。

因为vms68还要拔上Internet,所以不要defaultroute。

在j128上用ppp-onvms68拔上vms68,连通后telnet vms68,执行以下命令:

nohup sleep 30;ppp-onj128

然后在j128上断线,等待vms68拔入。拔通后,在j128上要执行以下命令:

route add -net 192.168.89.0 gw 192.168.89.69 ppp0

route add default gw 192.168.89.69 ppp0

ipfwadm -F -a m -S 192.168.88.0/24 -D 0.0.0.0/0

现在可再telnet vms68,在vms68上拔号上网,这样j003可通过j128,再通

过vms68上网,我也不用付任何费用。

二.Win98与Linux之间的互拔:

请看图二:

我家里: 办公室:

机器名:j128 机器名:vms68

OS: RedHat5.1 OS: RedHat5.1

IP: 192.168.88.128 IP: 192.168.89.68

Internet

| [ttyS1] [ttyS0]

|网线 |

| |

机器名:j003 |

OS: Win98 ---------------------------

IP: 192.168.88.3 电话网

这里vms68要象第一步所说的,要配成允许拔入的ppp server。

这里主要是win98的配置,首先象上Internet那样,在拔号网络里新建一个连接,

要注意两点,一要设置连通后弹出终端窗口,二是最主要的,在“控制面板”里

选“调制解调器”,选用来连线的modem,选“属性”按钮,选“连接”,再选

“高级”按钮,再在“附加设置”里输入&C0S0=001。

为什么要这样做?因为win98自带的ppp client会自动退出当远端ppp server挂线

时,因此要骗一骗win98,要modem不要报告断线,并自动应答拔入。&C0就是要

modem不要检测carrier,s0=001要modem在响一下后就应答。

现在配vms68拔到j003,文件ppp-onj003如下:

# Script to initiate a ppp connection. This is the first part of the

# pair of scripts. This is not a secure pair of scripts as the codes

# are visible with the 'ps' command. However, it is simple.

#

# These are the parameters. Change as needed.

TELEPHONE=xxxx # The telephone number for the connection

#ACCOUNT=ppp # The account name for logon (as in 'George Burns')

#PASSWORD=xxxx # The password for this account (and 'Gracie Allen')

LOCAL_IP=192.168.89.68 # Local IP address if known. Dynamic = 0.0.0.0
