Build a VPN Server Based on redhat9 (kernelversion2.4.20-8)

Build a VPN Server Based on redhat9 (kernelversion2.4.20-8) -- Linux Enterprise Application-Linux server application information. The following is a detailed description. I used the VPN configuration based on win2000/win2003. It took me a long time to configure the Linux-based VPN Server !!!!
A VPN (Virtual Private Network) is an extension of a Private Network. It can be connected through a shared Internet or a public Network.

Simulates a point-to-point dedicated connection to send data between a local computer and a remote computer.

Allows both parties to establish a free and secure point-to-point connection. The following describes how to quickly build a VPN Server.

Software to be downloaded:
Pptp-1.6.0-1.i386
Ppp-2.4.3-4.rhl9.i386
Pptpd-1.3.0-0.i386
Kernel-mppe-2.4.20-8.i686

Check whether the corresponding software package has been installed in your system. If not, use the upgrade.
Run the following commands:
Installation: rpm-ivh xxx. rpm
Upgrade: rpm-Uvh xxx. rpm
The installation is complete.

1. If version below 2.6.15-rc1 needs to add MPPE to kernel
# Rpm-kernel-mppe-2.4.20-8.i686

Run the following command to check whether the kernel MPPE patch is successfully installed:
# Modprobe ppp-compress-18 & echo OK
If OK is displayed
You do not need to add MPPE to the kernel

2. Install and update ppp
# Rpm-Uvh ppp-2.4.3-4.rhl9.i386.rpm

3. Install pptpd
# Rpm-ivh pptp-1.6.0-1.i386

4. edit/etc/pptp. conf
You only need to enter the last two rows:
Localip 192.168.100.1 // define the IP address on the server (that is, the ip address of ppp0 after the connection)
Remoteip 192.168.1.1-30 // define the Client IP address.
Save.
5. edit/etc/ppp/chap-secrets
You only need to add:
"User" pptpd "password" * // modify user and password to your username and password.
Or:
"User" pptpd "password" 192.168.1.1 // after replacing * with an ip address, it is the ip address after the client is connected.
Save.
6. edit/etc/ppp/options.ppt pd
You only need to add:
Ms-dns 202.101.172.35 // Replace the ip address with your dns ip address.
Save.
7. Start the service.
/Etc/rc. d/init. d/pptpd start or service pptpd start

8. Use the win system to create a new vpn connection. Enter the Server ip address, user name, and password.


I just tested it in the LAN and can use it normally. If you have any questions, please feel free to advise me!
