    What OS X server process is using port 20222?

    [nirvana:/etc] admin% netstat -aA
    Active Internet connections (including servers)
    Socket Proto Recv-Q Send-Q Local Address Foreign Address (state)

    <snip>

    445477c tcp4 0 0 *.20222 *.* LISTEN

    Through packet capture I also find this 10.2.6 Xserve attempting to reach one of our other Xserves on port 20222. I’d like to know why and turn it off. With netstat I also find /tmp/slpRAdmin_ipc active. Can anyone tell me what instantiates slpRAdmin_ipc?

    Other info:

    – At a time in the past, Server Status on this Xserve was used to check that other Xserve. The reference to that server has been removed from Server Status.

    – FWIW, according to IANA service port 20222 is for ipulse-ics – Ericsson iPulse ICS (Ipulse Cluster System) protocol.

    – Searching through the ADC docs I don’t find any reference to slp_ipc and no reference connecting SLP to the use of the IPC service port. Also, with 10.2 SLP was deprecated in favor of Rendezvous.
