<TD class=14px>一、操作环境: <BR><BR>机器系统与配置:三台机器的关健部件 <BR>第一台:台式机,双网卡,8139和8029,操作系统RedHat 8.0 <BR>第二台:Toshiba notebook,PC卡。RTL-8139/8139C/8139C+,操作系统RedHat 8.0 <BR>第三台:台式机,8029网卡,操作系统windowme <BR>Hub[集线器]:Tp-Link 10M,8口 <BR>ADSL,乙太口,非路由。 <BR>二、网卡设置如下: <BR>在第一台机器的双网卡的接法:把ADSL接在eth0上,把eth1接在HUB上。 <BR>第一块网卡的ip设置: <BR>ip地址:192.168.0.1 <BR>掩码:255.255.255.0 <BR>第二块网卡的设置 <BR>ip地址:192.168.0.2 <BR>掩码:255.255.255.0 <BR>在这两块网卡中,不要设置网关。 <BR>++++++++++++++++++++++++++++++++++++++++ <BR>第二台:Toshiba notebook的网卡设置 <BR>IP:192.168.0.6 <BR>掩码:255.255.255.0 <BR>网关:192.168.0.1 <BR>DNS:设置电信给的,或者下面的也行 <BR>202.96.134.133 <BR>202.96.168.68 <BR>++++++++++++++++++++++++++++++++++++++++ <BR>第三台机器的网卡设置 <BR>P:192.168.0.8 <BR>掩码:255.255.255.0 <BR>网关:192.168.0.1 <BR>DNS:设置电信给的,或者下面的也行 <BR>202.96.134.133 <BR>202.96.168.68 <BR>三、设置ppp拔号, <BR>1]删除原来的ppp的ADSL链接。 <BR>如果redhat-config-network原来已经用 redhat-config-network设置的ppp的ADSL连接拔号,用下面的命令调用删除。 <BR>#redhat-config-network <BR>2]在终端上以root权限运行 <BR>#adsl-setup <BR>进入设置过程: <BR>Welcome to the ADSL client setup. First, I will run some checks on <BR>your system to make sure the PPPoE client is installed properly... <BR><BR>LOGIN NAME <BR><BR>Enter your Login Name (default root): ADSL提供商给的用户名,写在这里 <BR><BR>INTERFACE <BR><BR>Enter the Ethernet interface connected to the ADSL modem <BR>For Solaris, this is likely to be something like /dev/hme0. <BR>For Linux, it will be ethX, where X is a number. <BR>(default eth0): eth0这是ADSL通过第一台机器的第一张网卡eth0提供上网 <BR><BR>Do you want the link to come up on demand, or stay up continuously? <BR>If you want it to come up on demand, enter the idle time in seconds <BR>after which the link should be dropped. If you want the link to <BR>stay up permanently, enter no (two letters, lower-case.) <BR>NOTE: Demand-activated links do not interact well with dynamic IP <BR>addresses. You may have some problems with demand-activated links. <BR>Enter the demand value (default no):在这里按一下回车就行了。 <BR><BR>DNS <BR><BR>Please enter the IP address of your ISPs primary DNS server. <BR>If your ISP claims that the server will provide dynamic DNS addresses, <BR>enter server (all lower-case) here. <BR>If you just press enter, I will assume you know what you are <BR>doing and not modify your DNS setup. <BR>Enter the DNS information here: 202.96.134.133这是DSN,最好用你本地电信给的 <BR>Please enter the IP address of your ISPs secondary DNS server. <BR>If you just press enter, I will assume there is only one DNS server. <BR>Enter the secondary DNS server address here: 202.96.168.68这是第二个DNS,也是电信给的。 <BR><BR>PASSWORD <BR><BR>Please enter your Password:在这里把ADSL提供商给的密码写上 <BR>Please re-enter your Password: <BR><BR>USERCTRL <BR><BR>Please enter yes (two letters, lower-case.) if you want to allow <BR>normal user to start or stop DSL connection (default yes): yes <BR><BR>FIREWALLING <BR><BR>Please choose the firewall rules to use. Note that these rules are <BR>very basic. You are strongly encouraged to use a more sophisticated <BR>firewall setup; however, these will provide basic security. If you <BR>are running any servers on your machine, you must choose NONE and <BR>set up firewalling yourself. Otherwise, the firewall rules will deny <BR>access to all standard servers like Web, e-mail, ftp, etc. If you <BR>are using SSH, the rules will block outgoing SSH connections which <BR>allocate a privileged source port. <BR><BR>The firewall choices are: <BR>0 - NONE: This script will not set any firewall rules. You are responsible <BR>for ensuring the security of your machine. You are STRONGLY <BR>recommended to use some kind of firewall rules. <BR>1 - STANDALONE: Appropriate for a basic stand-alone web-surfing workstation <BR>2 - MASQUERADE: Appropriate for a machine acting as an Internet gateway <BR>for a LAN <BR>Choose a type of firewall (0-2): 2 <BR><BR>Start this connection at boot time <BR><BR>Do you want to start this connection at boot time? <BR>Please enter no or yes (default no):yes <BR><BR>** Summary of what you entered ** <BR><BR>Ethernet Interface: eth0 <BR>User name: ADSL用户名 <BR>Activate-on-demand: No <BR>Primary DNS: 202.96.134.133 <BR>Secondary DNS: 202.96.168.68 <BR>Firewalling: MASQUERADE <BR>User Control: yes <BR>Accept these settings and adjust configuration files (y/n)?y <BR><BR>三、在/etc/rc.d/rc.local中加入如下: <BR><BR>echo 1 > /proc/sys/net/ipv4/ip_forward <BR>iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o ppp0 -j MASQUERADE <BR><BR>四、重新启动机器。就OK了。</TD></TR></TBODY></TABLE> |
