This section is intended to give system administrators a list of configuration tests to help them toward a working system.
netstat can print network connections, routing tables, interface statistics, masquerade connections, and multi cast memberships. with these command options we list all the TCP/IP connections with reference to the programs that have opened these TCP/IP sockets.
Port 32768 and 32768 is used by the NFS layer within D-Cache which is based upon rpc, this service is essential for rpc.
Port 111,1939 and 33808 is used by portmapper which is also involved in the rpc dependencies of D-Cache.
Port 34075 is for postmaster listening to requests for the Postgres database for D-Caches SRM application.
33823 is used for internal D-cache communication.
2811 is used to Communicate to the the client.
8443 is the SRM port.
2288 is used the web interface to D-Cache.
22223 is used for the D-Cache admin interface.
22125 is used for the D-Cache Dcap Protocole.
22128 is used for the D-Cache GSI enabled Dcap Protocole.
22158 is used for the D-Cache admin interface.
33080, 22128, 22125 is used for D-Cache in some way but I am not sure what.
Since D-cache is built around a replacement of NFS to manage the file system rpc is deeply coupled to D-Cache here is a dump of rpcinfo -p on a combined pool and admin node.
