Tcp ip port open but no such process (merged: Release A Port)

i want to kill a tcp connection by killing its pid
with netstat -an i got the tcp ip connection on port 5914
but when i type ps -a or ps-e there is not such process running on port 5914
is it possible that because i do not log on with proper user account i can not see that process running?

You need lsof to see pids and ports, generally speaking. Some OS have network artifacts in a per proc directory subtree like /proc/$PID/, so you can find the port there through an entry name. The ps can show you the command line, but that does not have to reveal any socket ports.

I assume this to be the wrong forum.
Does your netstat provide the -p option? It will output the PID of the process, then.

i tried lsof.
i am not that much familiar with unix.
when i type lsof it gives me lots of information in command line in a way that i can not see the previous commands that i typed (is there any command like /p that bring information page by page?)
but in that given information from lsof i can not find neither the port i see the port 5914 nor its corresponding ip that i saw in netstat -a for that particular port.
is there any way too release that port?

yes excuse me i post it on related forum

one of my system ports are busy and i dont know how to kill it
in netstat -a i see that the port are being used with a given ip but in ps -e i can not find that port being used by a process.
how can i kill that process or release that port.

Use the less (or more ) command :

netstat -tlp | less
# netstat -tlpn
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 127.0.1.1:53            0.0.0.0:*               LISTEN      1113/dnsmasq
                              ^--- port                                         ^--- PID

Can't the gods move a thread to a new forum? It's just rdbms values!

The lsof is most portable:

netstat -tlp |grep <port_no>
 
lsof | grep <port_no>

i tried but it didnt work it seems that the netsat tell me that such pid exist but in real there is not such a process.
here is the scenario
i connected to this server as a client and run a backup application on client.
the server use the port 5914 for this application.
withnetsat i can see that this port is in listening state and even the connection between server and client is in establishment state but there is not really anything about that pid in ps or lsof
is it really possible?

Is there any virtualization on this box? :smiley:

Share some of the output with us, sanitized if necessary.

thanks i am not at the office but i will explain more when i use netstat it says
that not all processes could be identified,non-owned process info will not be shown you would have to be root too see it all.
do you thinks because of wrong user it can not identify the process?
here is the connection that i want to kill with its port no.(netstat)
tcp 0 0 10.20.111.14:5914 10.20.110.1:1112 established

netstat -nlpn did not give me any further information about this connection

If you are not root, you cannot see other people's processes. You cannot be sure who is using a port but it is not your process. Can you move your server to another port?

Usually, when a high (>1023) port is connected to a low port, the high port is randomly assigned on a user client socket() call and the low port is where it connected, as low ports are restricted to root only at the time of binding. Port 1112 is Intelligent Commiunications Protocol or mini-sql, nominally, but could be anything. Service Name and Transport Protocol Port Number Registry Is 1112 in /etc/services ?

As DGPickett noted you cant see the output of lsof if the process using port 5914 is not owned by you or if you do not have root privileges...so can you post the output of the following cmd...

lsof -i:5914

yes i am definitely sure that 1112 port for client is a random port because i run this particular application in another client connected to exact similar server although the server port was 5914 the client port was different from 1112.some other random port.i have to mention that when i used the so called "server" it is not really a server it is a high tech optical equip that use unix bash shell for operating sys.and for logging on to different unit of this equip i should use ssh.

when i type lsof -i | 5914
here is the output
sh: 5914: command not found

Pls run the commands DGPickett proposed in post #2 and post output here WRAPPED IN CODE TAGS so we can see what your problem is. And, please, enter them as posted; don't modify at all!

EDIT: by moderators merging two threads, post #2 has become #8 ... pls have in mind...

You are right. I'll transfer the thread to where it belongs.

and the lsof -i | grep 5914
has no output.
that is the result with no modification

There's no port 5914 in that output; I presume the process is gone. In post#11, you show

tcp        0            0 10.20.111.14:5914                10.20.110.1:1112          established 

. Neither port is found in the IANA services file, so both are locally/user defined, and it's difficult to tell the client from the server. Do you have access to node 10.20.110.1 to run a netstat over there?
BTW - you don't need netstat -a ; netstat -t... will do...

that is the problem because there is no 10.20.110.1 in the network anymore.the client is disconnected for a long time but the server think that this connection still exist.
