    Ports 623 & 624


    I have installed Mandrake 10.1 on a double Xeon that serves as:

    a) Webserver
    b) MailServer
    c) Samba Server
    d) dns server
    e) Application Server (Java RMI)

    I am running nmap localhost and all seem to be ok with my open ports.

    When I try nmap with the static ip, I get this:

    623 unknown filtered
    624 unknown filtered

    I have no idea what this is all about! As far as I know there is no known service using these ports and I do not use a firewall to filter them! Is there any possibility of introtion ? What should I do in this case?

    I'm not sure quite what is going on, but this list of ports says that the ports do:
    asf-rmcp 623/tcp ASF Remote Management and Control Protocol
    asf-rmcp 623/udp ASF Remote Management and Control Protocol
