python socket.connect -> timed out why?

I'm fairly naive in this regard. I'm not sure why my connection is timing out. Thanks in advance.

#!/usr/bin/env python
import socket

def socket_to_me():
    socket.setdefaulttimeout(2)
    s = socket.socket()
    s.connect(("192.168.95.148",21))
    ans = s.recv(1024)
    print(ans)

the trace back generated by this code

Traceback (most recent call last):
  File "logger.py", line 12, in <module>
    socket_to_me()
  File "/home/drew/drewPlay/python/violent/networking.py", line 7, in socket_to_me
    s.connect(("192.168.95.148",21))
  File "/usr/lib/python2.7/socket.py", line 224, in meth
    return getattr(self._sock,name)(*args)
timeout: timed out

its a fake address, i think you are reading violent python if you want to make that work, type socket.gethostname() instead of fake ip address it will get connected to your machine.This is my code:

    def Socket_to_me(ip,port,time):
        try:
            s = socket.socket()
            s.settimeout(time)
            s.connect((ip,port))
            ans = s.recv(1024)
            print(ans)
            s.shutdown(1) # By convention, but not actually necessary
            s.close()     # Remember to close sockets after use!
        except socket.error as socketerror:
            print("Error: ", socketerror) 

call the method by:
Socket_to_me(socket.gethostname(),1234,10)

Change 192.168.95.148 to 127.0.0.1 (localhost - connecting to yourself) and run this program on the same machine. That way you'll have something to connect to.

You don't need to alter the default timeouts for all new sockets, instead you can just set the timeout of that particular connection. The value is a bit low though, so increasing it to 10-15 seconds will hopefully do the trick.

First, do this:

s = socket.socket()

Then:

s.settimeout(10)

And you should use "try:" on the connect, and add:

except socket.error as socketerror:
    print("Error: ", socketerror)

This will bring up the systems error message in your output and handle the exception.

Modified version of your code:

def socket_to_me():
    try:
        s = socket.socket()
        s.settimeout(2)
        s.connect(("192.168.95.148",21))
        ans = s.recv(1024)
        print(ans)
        s.shutdown(1) # By convention, but not actually necessary
        s.close()     # Remember to close sockets after use!
    except socket.error as socketerror:
        print("Error: ", socketerror)
