Netstat|grep 3050 says:
----
bash-2.04$ netstat |grep 3050
Proto RefCnt Flags Type State I-Node Path
unix 1 [ ] STREAM CONNECTED 3050 /tmp/.ICE-unix/1962
----

So it seams it is connected (hmmm interesting).
I notice that I am the owner (as user ed) of the i-node!! Let's do a restart
of the linux machine:
Restarting the interbase server with ibmgr -start =>>>> it says that is
running already (root starts interbase in the rc.local), and YES I can
connect with gsec !!!!???!!!
And netstat says that the address isn't in use !!! Good news .... but why
==>

Hmmm, this is weird!!!
Nothing changed within the last try, besides that I clean some files in the
home dir!!
How can I see who was connecting to this port ?, that is, who is using the
above i-node ?
(what is happening !!!!)
