SSH Intranet Port Forwarding combat
Guide
As you know, SSH is a secure transport protocol that is used more on the connection server. But in fact, in addition to this feature, its tunnel forwarding function is more attractive.
If the Linux server between the two intranet needs to log in with each other, or need to access a port on the i
Firewalls and switches are still commonly used. So I studied how firewalls and switches implement Intranet/Internet isolation. Here I will share with you, hoping to help you. With the maturity and rapid development of network and Internet technologies, more and more enterprises and institutions have begun to set up networks to automate office work and share Internet information. However, security issues have also emerged. iMaxNetworks (memory network

Note that the this documentation, referring to an IP address as an IPv4 address or an IPV6 address was a semantic property O f the address, not just the length of the byte slice:a 16-byte slice can still is an IPv4 address.

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
The Android interface is made up of layouts and components, and the layout is like a frame in the building, and the components are the bricks in the building. Components are arranged according to the layout requirements, which makes up the interface that the user sees. The five major layouts for Android are linearlayout (linear layout), Framelayout (single frame layout), relativelayout (relative layout), Ab

StoryboardsIn Xcode, Storyboard is a tool that allows us to visualize the application interface, you can first see the layout area of one or several iOS device screen sizes in the storyboard file, and then you can get from the component library (Object Library), you can also define the connection between screen layouts by dragging and dropping components into the layout area of the screen (such as buttons, pictures, text boxes, labels, etc.).In Xcode
After the lesson, I found that I am interested in the layout of Android, because the UI is the most intuitive to us, everyone wants to pursue a beautiful program. After Class I compare the book and then search the information on the internet roughly summed up a bit.There are a few of the layouts we use in Android: LinearLayout (Linear layout), Relativelayout (relative layout), tablelayout (table layout), Absolutelayout (absolute layout), Framelayout (

Many programs in the local area network can be applicable, but between the external network and intranet and between intranet and intranet is not feasible. The problem is NAT, this article will introduce the next 5 Nat penetration method, solve the internal and external network exchange. 1. Fully conical (full Cone) NAT

The author of the school through ADSL set up routes to share the Internet. The extranet gateway and DNS are 10.0.0.138, the external network port IP address is 10.0 0.1, and the subnet mask is 255.255.255.0. Self-built sites are placed on the server, on the server has been

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
