port triggering vs port forwarding

You can bind the remote server port Remote_port to the local port, where-c is data compression,-f is the background operation, only when the user name password is prompted to the foreground. -N is not a remote command, which is useful in the case of only port forwarding. -G allows the remote host to connect to the loca

port name. Click the port number to configure port properties. The actual port rate is displayed. If the port is not connected, it is displayed --. Full duplex mode, half duplex. If the port is not connected, it is displayed --.

three-layer switch port, meaning that the limit is three layer switch port uplink and downlink traffic control, similarly, if the three-layer switch port is not connected to the PC, but a two-layer switch, then the lower-level devices can be on the upper bound speed limit. Note: Each interface supports only one policy per direction, and one policy can be used f

to your server, make a forwarding setting on the router, which is the port mapping setting that allows Internet users to send requests to the router and forward them to the server or Web site you have established. This is the port mapping. Because the different router manufacturers have different names, some are called virtual servers, some are called NAT settin

The Ethernet port of a vswitch has three link types: 1. Access user mode; 2. Trunk link Trunk mode; 3. Hybrid is similar to Trunk but more advanced than trunk; (1) Access Port: Only the Ethernet frame of the default vlan is allowed, that is, only one vlan can belong to. The Access port is tagged with a vlan after the Ethernet frame is received, and the vlan label

What is port ing? Port ing is also called port forwarding. The port ing process is like your home is in room 2410, Building B, in a residential area. Your friend came to you and found the door of the residential area. I don't know which layer you live on? I asked the guard w

the forwarding table, the access user first performs MAC address authentication, after the MAC address is successfully authenticated, perform IEEE 802.1x authentication. This user is allowed to access the network only when both authentication methods are successful. In this mode, the port allows only one user to access the network, that is, the first user who passes the two authentication methods. Www.2cto

port is VLAN 1 when the port receives a message without VLAN tag, the message is forwarded to the port that belongs to the default VLAN (if the port's default VLAN ID is set). When the port sends a message with VLAN tag, if the VLAN ID of the message is the same as the default VLAN ID of the

Reference: https://www.xuebuyuan.com/3182300.htmlThe concept of port:In Network technology, ports (port) have roughly two meanings:One is the physical port, for example, ADSL Modem, hub, switch, router used to connect other network devices interface, such as RJ-45 Port, SC port and so on.The second is the logical

Development is based on Node. js WEB applications are very convenient, but the service port is very painful. Because Linux kernel requires that common users only use port numbers greater than 1024, so common users can run Node. the js service cannot listen to port 80. Note: Do not use the ROOT user to run Node. js service! This will lead to unpredictable security

Today, we will summarize the Packet Handling process for the three ports in a vlan. An Access port is generally used to connect to the Access layer and can only belong to one vlan. In general, directly connect to the Acess port of the PC. Receive a packet and check whether there is VLAN information. If no VLAN information exists, append the PVID of the port and p

What is port ing: Port ing (NAT or napt) refers not to a port in the physical sense, but to a port in the TCP/IP protocol. It is a logical port. Port ing: if a computer on the Intranet needs to access the Internet,

From FoolishQiangblog Some people often ask me this question "how to enter the intranet" and how to answer it. In summary, it is a sentence "break through the gateway and use port redirection to enter the intranet ". The first choice is to break through the gateway (GetWay), which is easy to understand, because an intranet must always access the internet through the gateway. As for how to break through the gateway, this is no different from accessing

packet and determines whether VLAN information exists. If yes, it determines whether the hybrid port allows data from this VLAN to enter. If yes, it forwards the packet, otherwise, discard (in this case, the untag configuration on the port does not need to be considered, and the untag configuration only works for sending packets). If it does not exist, append the PVID of the
