I have never understood why. Today I found that the test environment is 64-bit, And the pptpd I installed is a 32-bit package. Find the reason. Download and install it again. OK. Normal. The installation document (the installation information comes from the network, which is slightly modified in this article. Save as install. sh and modify permissionsChmod777 instll. sh run sh install. sh ):

Note:
1. The following is the installation package for the 64-bit environment. For a 32-bit environment, you only need to modify the comment line after ##32 #64.
2. localip is the ip address of the vpn pipe, and remoteip is the ip address range allocated to the client connection.
3. Change "ms-dns" to "available local dns ".
4. Information stored in chap-secrets client connection information is in sequence: User Name, service name, password, and allowed ip address. The service name is defined in the name of options.ppt pd. The default value is pptpd.
