| Hi there,
I would like to know which process opens TCP/IP port 10100. and who is the
owner of the process.
The machine is Sun E450, solaris 8.
when i execute command netstat, the output is below
[dbm@dbm /user/dbm]$netstat -na | grep 10100
*.10100 *.* 0 0 24576 0 LISTEN
203.239.148.41.10100 203.239.148.41.65294 32768 0 32768 0
CLOSE_WAIT
203.239.148.41.10100 203.239.148.41.65341 32768 0 32714 0
CLOSE_WAIT
203.239.148.41.10100 203.239.148.41.65345 32768 0 32714 0
CLOSE_WAIT
[dbm@dbm /user/dbm]$
Thanks in advance

if lsof is not installed you can use
bash# list=`ps -e -o pid` ; for item in $list ; do pfiles $item | grep port
| grep 10100 && echo $item ; done
to get the pid of the process.
