TIMEOUT=5
def ping(ip,port,timeout=TIMEOUT):
try:
cs=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
address=(str(ip),int(port))
status = cs.connect_ex((address))
cs.settimeout(timeout)
#this status is returnback from tcpserver
if status != NORMAL :
print ERROR
else:
print NORMAL
except Exception ,e:
print ERROR
print "error:%s" %e
return ERROR
return NORMAL
if __name__=='__main__':
if len(sys.argv) < 3 :
print ur'请按照如下格式使用: ./tcp.py www.jb51.net 80'
sys.exit(1)
ip = sys.argv[1]
port = sys.argv[2]
try:
timeout = sys.argv[3]
except IndexError ,e:
timeout=TIMEOUT
ping(ip,port,timeout)
希望本文所述对大家的Python程序设计有所帮助。
