NTP server: Network time Protocol (NTP) is a protocol used to synchronize the timing of a computer, which allows the computer to synchronize its servers or clock sources (such as quartz clocks, GPS, etc.) It provides high-precision time correction (less than 1 milliseconds on LAN versus standard, dozens of MS on WAN) and can be referred to as a cryptographic ackn

I do not know how long has not updated the blog, this is actually long ago wanted to write but a drag is a few months, the recent procrastination is really crazy outbreak. Let's talk about what you want to write about today, but it's very simple, that is, how to use PowerShell to get a computer's public IP address in real time.
Openvpn is actually used for transmission at the application layer. You can select UDP/TCP as the transmission protocol. UDP is more commonly used. The reason is described in this article.
Why openvpn network?
If I want to access the network resources of the Organization at home, VPN is a good choice, but in general, setting up a VPN requires a VPN Server, that is, at least one real IP
Recently, the server is configured locally and the home bandwidth does not have a fixed IP address. Therefore, you must obtain your own public IP address. The server version of CentOS6.
Each site has a unique, public IP address that anyone can access from anywhere.
Internet Protocol Internet Protocol (IP) does not need to be introduced--we use it every day. Even if you don't use it directly, when you enter website-name.com on the browser, it looks for the IP
In a Kering host environment, typically all hosts in an office network do not have a public IP address, but they are able to access the Internet through a router (gateway) device with an IP address, which requires only NAT and forwarding capabilities. A device with such a fu
different network.to achieve communication between the two networks, you must pass through the gateway. If the host in Network a discovers that the destination host for the packet is not on the local network, forwards the packet to its own gateway, which is then forwarded by the gateway to Network B's gateway, and the gateway of Network B is forwarded to a host on network B.(as shown in the attached drawings). The process by which network a forwards packets to network B. So, only set up the
How does CentOS obtain the public IP address from the command line?
Recently, the server is configured locally and the home bandwidth does not have a fixed IP address. Therefore, you must obtain your own
This article mainly introduces the method of obtaining the IP address of the local public network, using the ip138 data, we refer to the use of it. The code is simple, look directly at the code nbsp; Code as follows: using System; Using System.Net; Using System.Text.RegularExpressions; nbsp; namespace Keleyi.com {nbsp; nbsp;
