. VPN can be understood in this way, Linux clients use a virtual network device PPP0 (Windows clients can also be understood as a VPN virtual network card), connected to the server's virtual networking device Ppp0, so that the client joined the server-side ppp0 on the network. Localip is the IP address that can be assigned to the server-side ppp0, and REMOTEIP wi

1) Install DKMS package RPM--install dkms-1.12-2.noarch.rpm This is supported by dynamic kernel modules. You need to use it at the kernel level to simplify installation and configuration. This will make almost everything transparent to the user during the installation process. 2) Install the PPP kernel module RPM--install kernel_ppp_mppe-0.0.4-2dkms.noarch.rpm The Point-to-Point Protocol installs your "modem" or any device that makes up your connection. This is part of your core. 3 Determi

In Linux, any software accesses the Internet through proxy (non-vpn). in windows, SocksCap32, ProxyCap, FreeCap, and Proxifier can access the Internet through proxy.

be done using the skb_copy_expand function. Fill in the ipip header field after the allocation. At this point, most of the logic of the ipip protocol has been clearly described. The following is a function value note. Static int This function is the place where the application interacts. To put it bluntly, it is the place where the Linux system commands ifconfig and IP commands are used as an excuse, creating tunnels, deleting tunnels, changing IP a

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

VPN Client Connection Linux server access slows down how to solve There are three ways to solve the problem: Method One: Edit pptpd source code, increase MTU; Method Two: Use a script to increase the MTU after the PPTP interface is connected to the up; Method III: Do not use MPPE encryption; The first, although fundamentally solves the problem, but because the level problem gives up; the third becaus

My Vyatta operation has been very good, with Ros and Cisco do tunnel connected to Vyatta run OSPF used to turn the wall, the effect has been good. When you use Windows to connect to a VPN, however, you often open the page timeout, but the ping is normal everywhere, so you suspect an MTU or MSS problem. After several twists and turns, when the Web page timed out, a large number of exceptions occurred in the Vyatta log: 21:02:39 Xirang kernel: [483817
