If I use the RSP probe to monitor a Linux server on the other side of a fire wall, what ports do I need opened? I know that ssh is necessary, but are there other ports as well?
Here is the Knowledge Doc for your question.
TCP Ports Needed by the rsp Probe
To retrieve remote data, the rsp probe uses:Commands on UNIX/Linux systems on SSH, using port 22
Note: The probe supports only password-based and key based authentication. Keyboard-Interactive and authentication less method are not supported. If the unix-based remote server is not password-based or key-based authentication that is enabled, the rsp probe is unable to discover the remote host.
