Hello,
You can use this script :
#!/bin/ksh
#
# find from a port the pid that started the port # usage : port2pid.sh
<portnumber> #
line='------------------------------------------------------------------
-------'
pids=`/usr/bin/ps -ef | sed 1d | awk '{print $2}'`
# Prompt users or use 1st cmdline argument if [ $# -eq 0 ]; then
read ans?"Enter port you like to know pid for: "
else
ans=$1
fi
# Check all pids for this port, then list that process for f in $pids do
/usr/proc/bin/pfiles $f 2>/dev/null | /usr/xpg4/bin/grep -q
"port: $ans"
if [ $? -eq 0 ] ; then
echo "$line\nPort: $ans is being used by PID: \c"
/usr/bin/ps -o pid -o args -p $f | sed 1d
fi
done
exit 0
-------------------------

Regards,
Omer.

Subject: Investigating processes on open ports
Hello,
I was installing jboss 3.2.6. on Solaris 10 SPARC (Sun Netra 100). After
installation jboss could not start as some of the needed ports were
already opened. I tried to evaluate who uses the open ports with
following steps:
1) Jboss reports that he need three ports which are already in use:
1098, 4444, 8080.
2) I try to telnet to these ports and I see that really some process is
listening on these ports.
3) I am using netstat to gain some more information about listener on
specific ports: 8080, 4444, 1098. This is what I get:
bash# netstat -an|grep 8080
*.8080 *.* 0 0 49152 0 LISTEN
bash# netstat -an|grep 4444
*.4444 *.* 0 0 49152 0 LISTEN
bash# netstat -an|grep 1098
*.1098 *.* 0 0 49152 0 LISTEN
4) I am trying to find out a little bit more with command
/usr/local/bin/lsof -i :8080 (4444, 1098), but I do not get any output
for these ports.
5) Now I am checking configuration files under /etc and I am searching
for configuration file that contains string 4444 or 1098. I do not
execute the check for 8080 port, as in the meantime I have found out
that this port is used by Oracle-MTS.
I am using following command:
bash# find . -name '*' -a -type f -exec grep 1098 \{} \;
I do not get any output, meaning, no configuration file contains strings
which could lead me to some connection to our ports.
6) For the port 1098, I think it is used by sun cluster manager
rmiactivation, but I am not sure. Could be Oracle uses this port as
well.
Nevertheless, I did not get any information about the process which uses
these open ports. Eventually I got an impression that all three ports
are used by Oracle 10g.
How will I find out more information about which processes (PID) is
currently using these open ports?
Thank you very much for your prompt answer.
Best regards,
Marijan Mumdziev
P.S. "I need to get this machine working as soon as possible. Please
help! Send email and I will summarize to the list. :)"
