Most of the logs for logging on to the linux pptp vpn user name pptpd are stored in files such as/var/log/messages,/var/log/daemon. However, after careful reading, the user name is not found in the logs, I don't know which account the user used to log on. So I looked at pppd man and found some environment variables, such as IPLOCAL and IPREMOTE. After testing, I found that PEERNAME is the user name, in this way, you can record in/etc/ppp/ip-up and/etc

You can build a virtual private network in countless ways. The minimal VPN implementation scheme consists of the Internet-connected ras pptp server, the Internet-connected client, and the PPTP connection between the above server and the client. As long as the ISP service or Internet connection is available, the client can establish a connection with your server from any corner of the world. However, most VP
customer, the ISP's pops must have the access server that allows the tunnel and the router that may be needed. The customer first enters the server by dialing. The server must be able to identify the connection.To establish a tunnel with a specific remote point, and then the server establishes a tunnel with the tunnel server, the user ID and password are usually used for authentication. In this way, the client establishes a direct conversation with the tunnel server through the tunnel. DoThis p
settlement.
The transmission network used by the tunnel can be any type of public interconnected network. This article mainly uses the Internet as an example to describe. In addition, you can create tunnels in the enterprise network. After a period of development and improvement, tunnel technology is currently mature, including:
1. SNA tunneling technology on IP Networks
When SNA data streams are transmitted over an enterprise IP network, SNA data packets are encapsulated in UDP and IP headers.

Data transfer phase
Once this 4-phase negotiation is complete, PPP begins forwarding data between the connecting peers. Each transmitted datagram is encapsulated within the PPP header, which is removed after it arrives at the receiving party. If you choose to use data compression in Phase 1 and you have completed the negotiation in Phase 4, the data will be compressed between transfers. Similarly, if you have chosen
