portube t  -p 3307 -R 127.0.0.1 -P 3306
portube tran  -p 3307 -R 127.0.0.1 -P 3306

portube l -p 9917 -P 9907
portube listen -p 9917 -P 9907

Locally, the ip1:port1 host and the ip2:port2 host are actively connected. After the connection is successful, the data is forwarded between the two hosts. Short and long connections are not supported.

portube s -l 127.0.0.1 -p 3307 -R 127.0.0.1 -P 9907
portube slave  -l 127.0.0.1 -p 3307 -R 127.0.0.1 -P 9907
