Problem description:When implementing Destination NAT, if you need to access the mapped public IP address from the Intranet, there will be some problems by default. You can ping the ing IP addre
Theoretically, as long as the computer connected to the network is accessible, it is difficult to implement it due to technical level or other reasons. For example, a computer in the LAN only opens Web Services, this service is only available for Intranet users, but there is no direct access for Internet users. Therefore, to allow Internet users to access system services in the LAN, port ing and other operations must be performed. Port ing is often us

1. Reinforce and infect the EXE file protection targets outside the system disk.
2. Start the keyboard record and copy the USB device file.
3. Record the target anti-virus software.
4. Capture the hash.
5. Obtain the target network environment. The workgroup is also a domain environment.
6. Search for any network management software on the host.
5. Search and download all the docxls ppt files on the host.

Use openvpn in linux to log on to the Intranet of the remote server
Requirement: in some environments with strict network requirements, we are unable to remotely access the company's Intranet in a remote location, which brings us great inconvenience. However, we can achieve it easily through openvpn, next we will introduce it.

On the Ali Cloud, the intranet of all virtual machines (cloud servers) created by the same account is directly connected. Azure, however, was completely different, a bit overwhelmed at first, and then groped for it--only virtual machines in the same subnet (subnet) in the same virtual network (network) in Azure could communicate directly through the intranet and share them with this blog post.

Bkjia.com exclusive Article] Speaking of enterprise network security protection, Internet security technology is mature, such as some firewalls, vulnerability scans, and intrusion detection have been well developed. Many enterprises have emphasized the deployment of Internet security products while ignoring the threat of Intranet security. In many cases, the real threat comes from the internal, and many confidential information leaks are caused by poo
In recent years, network security has become the core content of enterprise network deployment. Intranet is a major component of network applications, and its security has been paid more and more attention. According to incomplete statistics, 15% of the investment in building an intranet outside China is used to enhance the network security of the Intranet. Secur
I once saw an article on the Internet that introduced a method for direct access to the intranet. In fact, we only need to use the port ing tool to easily penetrate the intranet. Port ER is a tool like this. it is even more worth mentioning that it breaks away from the command line mode and provides a graphic interface operating environment. I. basic ideas

The existing server can access both inside and outside the network, can also be accessed by the extranet, binding the domain name. Intranet has a Web site to allow users to access the network (assuming the user killed without a VPN), as follows.
Intranet site address such ashttp://192.168.1.2/index.phpWhen an extranet user accesses my server http://mydomain.me/index.php , they can see and operate the same
As more and more Linux servers are installed on the Intranet, you must upload the installation disk to install software on each server. It is troublesome and time-consuming to configure the local yum service. You can install the yum service on a Linux server on the Intranet, and then other servers can directly modify the repo file to use the yum service.

Many of the calling resources (databases, web interfaces, etc.) in the intranet environment of the company are mapped by domain name-IP through the intranet DNS service.However, when the DNS mappings are changed, the resources connected in the application are not changed.Previously, it was generally considered that the Linux DNS cache resulted in a complete analysis today, with the following results:1.
