UNIX for Dummies Questions & Answers

Howdy Experts,

This is my first post here and I am posting because I have not been able to find an answer for this question.
How do you find out what process is listening on a given port? I do not have "lsof" available and how do we find this out without logging in as Root.

I know that this has been brought up several times and I have tried those suggestions but I could never get it to work.
Im using Solaris 10.

Folks,
All help will be monumentally appreciated

Sincerely,
King Koopa

Code:

#!/bin/ksh
        pfexec pfiles /proc/* 2>/dev/null | nawk -v port=$1 '
/^[0-9]/ { cmd=$0; type="unknown"; continue }
$1 == "SOCK_STREAM" { type="tcp" }
$1 == "SOCK_DGRAM" { type="udp" }
$2 == "AF_INET" {
        if ((port!="")&&($5!=port)) continue;
        if (cmd!="") {
                printf("%s\n    %s:%s/%s\n",cmd,$3,$5,type); cmd="";
        }
}'

oops... you said no root.... my oops...

you could always use sudo... true?

you need root access of some form.

so basically , I am a production support guy for this application XYZ , and i dont have root or sudo to root( thats the way things are here at my company) then there is no way i would be able to kill a rogue process that wont let go of my port? I can only su to a specific user that owns the application and thus the process owner would also be that very user.

Can netstat not help me in this case?

You can certainly run pfiles on processes you own. You only need to be root (or to have the rbac required privilege) for processes run by a different user.
