PAM has known issue with port 8550 is always queried when it make connection to target device with ssh/rdp.
There is KB describe this issue. And enhancement request is also raised for disable/enable query on SFA port(8550)
I am wondering if this behavior changed in latest PAM or lastest PAM still query port 8550 when make connection.
Also is there any other way to mitigate this problem other than reject package in firewall setting?
