Check process từ port trong Linux, Solaris, AIX

Mục đích: Xác định process từ port.

Cách dùng: 

./port2process.sh -p 2233

Script:

# vi port2process.sh

#!/usr/bin/ksh # # PCP (PID con Port) # v1.08 30/12/2008 sam@unix.ms # # If you have a Solaris 8, 9 or 10 box and you can't # install lsof, try this. It maps PIDS to ports and vice versa. # It also shows you which peers are connected on which port. # Wildcards are accepted for -p and -P options. # # Many thanks Daniel Trinkle trinkle@cs.purdue.edu # for the improvements! i=0 while getopts :p:P:a opt do case "${opt}" in p ) port="${OPTARG}";i=3;; P ) pid="${OPTARG}";i=3;; a ) all=all;i=2;; esac done if [ $OPTIND != $i ] then echo >&2 "usage: $0 [-p PORT] [-P PID] [-a] (Wildcards OK) " exit 1 fi shift `expr $OPTIND - 1` if [ "$port" ] then # Enter the port number, get the PID # port=${OPTARG} echo "PID\tProcess Name and Port" echo "_________________________________________________________" for proc in `ptree -a | awk '/ptree/ {next} {print $1};'` do result=`pfiles $proc 2> /dev/null| egrep "port: $port$"` if [ ! -z "$result" ] then program=`ps -fo comm= -p $proc` echo "$proc\t$program\t$port\n$result" echo "_________________________________________________________" fi done elif [ "$pid" ] then # Enter the PID, get the port # pid=$OPTARG # Print out the information echo "PID\tProcess Name and Port" echo "_________________________________________________________" for proc in `ptree -a | awk '/ptree/ {next} $1 ~ /^'"$pid"'$/ {print $1};'` do result=`pfiles $proc 2> /dev/null| egrep port:` if [ ! -z "$result" ] then program=`ps -fo comm= -p $proc` echo "$proc\t$program\n$result" echo "_________________________________________________________" fi done elif [ $all ] then # Show all PIDs, Ports and Peers # echo "PID\tProcess Name and Port" echo "_________________________________________________________" for proc in `ptree -a | sort -n | awk '/ptree/ {next} {print $1};'` do out=`pfiles $proc 2>/dev/null| egrep "port:"` if [ ! -z "$out" ] then name=`ps -fo comm= -p $proc` echo "$proc\t$name\n$out" echo "_________________________________________________________" fi done fi exit 0
