What process is listening on a certain port on Solaris?

Question

So I log into a Solaris box, try to start Apache, and find that there is already a process listening on port 80, and it\'s not Apache. Our boxes don\'t have lsof installed,

I think the first answer is the best I wrote my own shell script developing this idea :

#!/bin/sh
if [ $# -ne 1 ]
then
    echo "Sintaxis:\n\t"
    echo " $0 {port to search in process }"
    exit
else
    MYPORT=$1
    for i in `ls /proc`
    do

       pfiles $i | grep port | grep "port: $MYPORT" > /dev/null
       if [ $? -eq 0 ]
         then
           echo " Port $MYPORT founded in $i proccess !!!\n\n"
           echo "Details\n\t"
           pfiles $i | grep port | grep "port: $MYPORT"
           echo "\n\t"
           echo "Process detail: \n\t"
           ps -ef | grep $i  | grep -v grep
       fi
    done
fi
