Python - 프로세스 네트워크 연결상태 확인방법(tcpview)

tcpview처럼 프로세스별 네트워크 연결상태를 확인하는 방법을 알아보니 psutil 을 사용하여 확인이 가능하다고 하네요

psutil를 설치하고 조금 비슷하게 따라해봤습니다.

import psutil

def tcpview():
    strOut = ''
    strFormat = '%-30s\t%-5s\t%-15s\t%-20s\t%-5s\t%-20s\t%-5s\n'
    strOut = strFormat% ('process','pid','status','local address','port','remote address','port')
    strOut += '------------------------------\t-----\t---------------\t--------------------\t-----\t--------------------\t-----\n'
    
    for conn in psutil.net_connections():

        if conn.status == 'NONE':
            continue
        
        proc = psutil.Process(conn.pid)
        name = proc.name()
        pid = conn.pid
        status = conn.status
        local_ip = conn.laddr[0]
        local_port = conn.laddr[1]
        remote_ip = conn.raddr[0] if conn.raddr else ''
        remote_port = conn.raddr[1] if conn.raddr else ''

        strOut += strFormat%(name, pid, status, local_ip, local_port, remote_ip, remote_port)

    print(strOut)
