One, dynamic public network IP environment1, Environment Description:Routers are assigned a dynamic public IP and have routing management privileges, and Linux hosts are deployed in the routed intranet. How to implement external network SSH access to intranet Linux host?2. Solution:Use nat123 dynamic Domain name resolution to solve dynamic public network IP problems.3, the implementation process:Method One:
stop spoofing, the target computer will not be able to access the network normally, resulting in user O M accidents.
To sum up, there are many problems with ARP spoofing blocking methods. Therefore, Intranet security products should use this method dialectically.
1. Avoid being single and adopt multiple blocking methods

A man's martial arts: the idea of Intranet penetration testing (2)

When encountering obstacles, sometimes you can use different ideas to break through. In many cases, you can only stop here. Here are some of my summ

The shell method in the case is relatively simple. We only focus on the limited space, starting from obtaining permissions.Install BackdoorAfter entering the system, my RP was so lucky that it turned out to be the root permission...View passwd account informationDirectory tree structure:Because Intranet penetration is required and permissions may be lost a
Today to tell you how to use the port mapping, not through the Gateway Open intranet method.
First: The use of the premise
Need to have a public network of IP. If we now have a public network of ip:210.210.21.21
II: Tools to use
1.lcx.exe

Three: Method explanation
Method One: Use Lcx.exe to map.
(1) We will upload the Lcx.exe to the public network IP, in the public IP on the DOS environment in the implementation of Lcx–listen Port 1 Por

As we all know, SSH is a secure transport protocol, which is more used in connecting servers. But in addition to this function, its tunnel forwarding function is more attractive.
If the two intranet between the Linux server need to log in with each other, or need to access a port in the intranet, worry that there is no public network IP, you can use the method has Ngrok (https://ngrok.co

The current work environment cannot be connected to the Internet, but there are some wireless hotspots around, use a laptop to connect to the wireless network, you can access the Internet, but if you connect to the Intranet, you can not connect to the Internet, this is very troublesome, so I try to find some ways to solve this problem, so that the Intranet and the Internet can be connected at the same time
Environment Description:The router is assigned a dynamic public IP, and has router login administrative rights, and the Web server is deployed in the router's internal network. How to publish the intranet website to the extranet for public access?Solution:Intranet use nat123 dynamic Domain name resolution, real-time domain name fixed to the routing public IP, and then on the router to do site port mapping. When an extranet accesses a Web site, it uses

Point-to-point technology has been widely used in recent years, mainly represented by QQ, Skype, BT, Thunder, PPStream, PPLIVE, qvod. We can see that as long as the data volume is large, and the use of transit servers requires a certain amount of input applications, we can consider using P2P technology. There are two benefits: 1. It can reduce costs and investment. 2. Improve transmission performance. There are a lot of materi
