Greetings,



We have a application running on our websphere 5.1 enviroment. In one of our enviroments we suddently cant access the application due to what i think is a closed port. Do you guys know which port is used after the handshake sequence?



A=Client

B=Websphere



A contacts b using port 2809

b establish a handshake with A using port XXX

The session is now established during port/range?



netstat -an |grep "Running IP of Websphere Server"
