service. Let's talk about the FTP virtual server. Note that FTP has two ports, 20 and 21, both of which must be mapped, and the method is the same as above. First, disable the FTP service for the HASB-100 on another configuration page. Submit and save. Then, add two mappings to the Virtual Server Page. Just like HTTP, we will not talk about them here. In other settings, www.2cto.com has DMZ settings. By default, the DMZ settings are disabled. You must enable the functions of virtual servers in

=" 222 "/> to implement Remote port mirroring, you must configure a special vlan called Remote-probe VLAN, all reported images are transmitted to the Image Port of the destination switch through this vlan. Source switch: The switch where the monitored port is located. It forwards the image traffic up through the Remote-probe VLAN and to the intermediate switch o

You must enable this function to enable the virtual server in the LAN. Go to the vro and click "other settings"> "NAT"> "add ". Select "REDIRECT" as the rule ty

traffic to the Rspanvlan (in the case of a switch running iOS, you need to set up a different port as the reflection port); On the destination switch port, You need to set the forwarding of information in Rspanvlan to the target port of the connection monitoring host. iOS

If each port on a vswitch has a host. So without listening and learning, it is easy to cause a broadcast storm. The Spanning Tree Protocol STP is generated to solve such problems. How the Spanning Tree works: The international standard for Spanning Tree Protocol is 802.1b. the Network Bridge/switch that runs the Spanning Tree Algorithm communicates configuration information with other switches through the Network Bridge Protocol Data Unit BPDU withi

settings are complete. At this time, the Internet can access the internal 10.0.0.10 by entering the IP address of the HASB-100 in IE, of course, 10.0.0.10 to open the HTTP service. Let's talk about the FTP virtual server. Note that FTP is two ports, 20 and 21, both of which must be mapped to the vro port. The method is the same as above. First, disable the FTP service for the HASB-100 on another configuration page. Submit and save. Then, add two mapp

If you want to get a deeper understanding of how it works: Read "UNIX network Programming"Socket, we generally refer to a long connection, but there is a short connection, the correct explanation is:1. If it is a short link, use the Sync socket. such as HTTP servers, forwarding servers, and so on.2. If it is a long link, use an asynchronous socket. such as communication systems (Qq/fetion), webgame and so on.Introduce me to the construction of the env

When connecting a computer to a switch, it may take 30 seconds or more for the computer to communicate with the network. If you are in a hurry to use, 30 seconds of waiting is enough to make you feel very long. Let's see how we can speed up the port initialization process for the switch. Understanding the process of switch port initialization When you connect a device to a

　　Today to use Python to write a port detection applet to detect some specific service port is not occupied, suddenly found that they do not know how to query the Linux port is occupied, God, quickly learn.How Linux looks at ports1, Lsof-i: Port number is used to view the occupancy of a

There are many things worth learning about the router port ing settings. Here we mainly introduce how to set the TP-Link R460 router port ing. First, find the router address and the Intranet IP address of the user's computer. The hidden address of the TP-Link R460 router is 192.168.1.1. Open IE, ENTER the router address in the address bar, such as 192.168.1.1 (implicit), ENTER, and fill in the login name a

In the main menu midpoint "Nat", there will be a "NAT channel list" To install the Web server on the internal PC 192.168.1.2 as an example, the general default port for the Web is 80, set as follows: In the NAT channel list Mupltiple Port forwarding fill in the following content: Action:add Channel N1 Protocol:tcp Incoming

1. back up iptables # cp/etc/sysconfig/iptables/var/tmp first. Port 80 must be enabled, and the following three lines of IP address and lan must be specified: first, disable all port 80 and enable port 80 at the end of the ip segment 192.168.1.0/24. enable port 80 at the ip segment 211.123.16.123/24 # iptables-I INPUT-

There are many problems with router port ing on the network. For vrouters of various models, I have a question and answer topic below. I hope to cover all questions about using vro port ing. Please leave a message to add. First, find the router address and the Intranet IP address of the user's computer. The hidden address of the TP-Link R460 router is 192.168.1.1. Open IE and enter the router address in th

, listening, learning, forwarding, and failure. The entire process takes 15 seconds. Therefore, if you are sure what you want to connect to, you can terminate this process. Test the Ethernet Channel Configuration The next step is to test the Ethernet channel, which is bound with the switch port to provide more Ethernet connections. If one channel fails, the Ethernet channel usually provides redundancy. This
