Finally, we successfully configured packet forwarding from one interface to another on the firewall Linux machine using iptables. This article teaches you to connect your private interface to the Internet. Instead of bridging interfaces, You can route data packets fr
Tags: database server securecrt navicat SSH tunnel Port forwardingFor security reasons, the database server is typically deployed only on the intranet, or if it is deployed on a public network, but only for certain designated IPs. But if the data is eventually queried by the public, there will always be a channel to access the database. The following uses Navicat and SECURECRT to achieve database access to two different scenarios.Scenario One: The database server opens the SSH service on the pub

Have you ever encountered this situation? Your Firewall reports that a computer with a certain IP address in the LAN is attacking you, but the firewall does not prompt the name of the computer that is launching the attack, who is the computer under attack? (your computer may be poisoned )? One morning, you just went to work. After you turned on your computer and found that you couldn't

The Client IP address needs to be obtained in the project, and relevant information is searched on the Internet. Here I will summarize some of my usage.For future reference.Generally, we obtain the IP address through the following code:String IP = system. Web. httpcontext. C

In some requirements, it may be necessary to know some system information about the front-end programs connected to SQL Server, such as the computer name of the front-end connection, the IP address, when to start requesting the connection, and when to end the connection.If you are not familiar with SQL Server's system functions or views, this functionality may seem more complex, but in fact, the dynamic man

DHCP is a commonly used protocol service. It plays an important role in managing network IP addresses. So let's take a look at the relevant content this time. It mainly introduces DHCP addresses and other related content.

Running an operating system under a virtual machine, especially a Linux system, is already a very common practice. Sometimes you want to build a (simulated) server under a virtual machine for host access, such as setting up a telnet/ssh server. At this point, you will find that every time you start a virtual machine, VMWare assigns a dynamic IP address to the virtual machine system, which makes it inconveni
