voip port forwarding

Work often encounter problems like the following: A port on the engine room server only allows local access, such as Monit management port 2812 Port, Dell Server management port 1311; some servers in the computer room have no public network IP address, only allowed through the intranet IP connection, such as MySQL serv

First introduce the environment:1. The host computer's operating system is scientific Linux, kernel version 2.6.18, hostname spvm02,ip address 135.100.101.102, and VMware Workstation 8 deployed.2. Guest (virtual machine) This side of the installed operating system is windows 7.3. Guest uses the VMNET8 network card to achieve Internet access through the NAT protocol.The feature that needs to be implemented is that other computers in the host network use Microsoft Remote Desktop to telnet to the g

Brief introduction: Most people know that SSH is used to replace the R command set, which is used for encrypted remote logins, file transfers, and even encrypted FTP (SSH2 built-in), so SSH becomes one of the most widely used services, and SSH has another very With the function of its port forwarding tunnel function, using this function, so that some unsafe

This article for everyone to share is the Node.js port forwarding implementation code for your reference, the specific contents are as follows #!/sbin/node var net = require (' net '); function ProxyPort (srcport,destserver,destport) {var server = Net.createserver (function (c) {//' connection ' listener C.on (' End ', function () {console.log (' src disconnected '); }); var client =

Iptables and network segment port forwarding Environment Description: You need to submit all packets accessing port 80 of the 192.168.1.20 host to 192.168.1.31 host for processing. Therefore, you need to perform the following operations on the host 192.168.1.20: 1. enable the routing forwarding function 1 echo "1">/pro

The command takes effect immediately, and the configuration still exists after rebooting the system.Disadvantages:(1) UDP not supported(2) xp/2003 need to install the ipv6,win7 above the system to bring their own.Execute command:(1) Installation environment support (can not be performed if IPV6 is already installed)netsh

cannot be received by machine C, the switch should have a forwarding list (CAM). The AMC table is used to establish the correspondence between the MAC address and the port. A port can correspond to many MAC addresses, (It seems that only one can be created under 802.1x.) it seems that there is no problem. The problem is that Cam is dynamically updated in real ti

Because only one server (win2003 server) needs to run ASP programs and PHP applications on the server, and does not want to use IIS to run PHP applications.In addition, if you do not want to run ASP programs on Apache, you need a solution for coexistence of Apache and IIS. IIS is the built-in iis6.0 of Windows2003 server. Apache is apache2.2.8. First, download and install Apache Then, stop the automatically started IIS server and modify the IIS port t
