Se você executar ss
ou netstat
, os valores Recv-Q
e Send-Q
produzirão essa saída.
I.E
$ ss -nt
State Recv-Q Send-Q Local Address:Port Peer Address:Port
ESTAB 203 0 192.168.1.2:36122 198.xxx.xxx.xxx:80
CLOSE-WAIT 1 0 192.168.1.2:43870 140.xxx.xxx.xxx:80
Eu adicionei um programa python simples para demonstrar isso.
#/usr/bin/python
from time import sleep
from socket import *
import subprocess
if __name__ == "__main__":
sock = socket(AF_INET, SOCK_STREAM)
sock.setsockopt(IPPROTO_TCP, TCP_CORK, 1)
sock.connect(('www.google.com', 80))
length = sock.send("GET / HTTP/1.1\r\nHost: www.google.com\r\n\r\n")
sport = sock.getsockname()[1]
print "Length of sent data: {0}".format(length)
subprocess.call(["ss" ,"-nt", "sport", "=", ":{0}".format(sport)])
sock.close()
Que produz
Length of sent data: 40
