you will see all established and waiting connection.
check for lines with LISTENINg on it.
If something is runnning on port 389 you will see it.
netstat -a
You need "-a" option.

sorry it should be
#netstat -a

or better to see only daemons:
#netstat -a | grep LISTEN

In lines check that ldap or 389 doesn't exist in first column. It means that there is no daemon listening on port 389.

Another way is to telnet to the port, eg:

telnet localhost 389
netstat is the tool for the job, eg: to check the occupied port being used and the
appplication who use them, use command:

netstat –anP tcp

To find out the program listening
to a paticular tcp port

netstat -a | grep LISTEN | grep port-no

    check port 80:
    netstat -a | grep LISTEN | grep 80

man netstat
to learn more details.

and see http:Q_20887412.html

If you want to find out the process ID run on a particular port, you can use the following


echo -n "which port?> "
read port

for pid in `ps -ef -o pid | tail +2`
  foundport=`pfiles $pid 2>&1 | grep "sockname:" | grep "port: $port$" |
'{print $NF}'`
  if [ "$foundport" != "" ]; then
    foundproc=`pfiles $pid 2>&1 | grep "^$pid:"`
    echo "$foundproc, $foundport"
