Я пытаюсь провести простое тестирование. У меня есть следующая простая программа, взятая непосредственно из https://docs.python.org/2/library/simplehttpserver.html
import SimpleHTTPServer
import SocketServer
import sys
address = sys.argv[1]
port = int(sys.argv[2])
Handler = SimpleHTTPServer.SimpleHTTPRequestHandler
httpd = SocketServer.TCPServer((address, port), Handler)
print "serving at port", port
httpd.serve_forever()
Я запускаю ее следующим образом
$ python run-server.py 10.167.71.255 9000
serving at port 9000
, но когда я пытаюсь проверить соединение, используя nc на том же хосте я получаю ошибку ниже:
$ nc -zv 10.167.71.255 9000
nc: connectx to 10.167.71.255 port 9000 (tcp) failed: Permission denied
также см. Ниже:
$ ping 10.167.71.255
