OSerr = 23

[hannakt]

I get an OSError:23 when I am in a loop listening for socket connctions.
The error occurs after 4 successful runs thought the loop and reports the dummy data back to the client.
ON the 5th try, the error pops up.

The code was stolen from a similar application running successfully on Raspberry Pi.
I.E. if there are subtle differences in how the socket calls should be handled, I didn't catch them.

What is OSError:23 ???

Any ideas?

P.S. first time posting to any forum, so I'll get formatting done better next time.

I get this error:

File "/flash/sockets/st_02.py", line 41, in listen
OSError: 23
>>>

On this Executed code:
[CODE]
def listen():
HOST = '' # accept connections from anyone, else supply IP address of client.
PORT = 65000

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
s.listen(7)

print (" Socket Server is : 'Listening' ")

while True:
#41 --> c, addr = s.accept() # Get socket object and client IP and port addresses ************ Line # 41 *******************
print ('Accepted connection from ',addr)
cmd = c.recv(1024)
if not cmd: break
cmd = 'get_temp' #fake it for now

print ( 'Command received = ' + str(cmd) )
print (cmd)
if cmd == 'get_temp':
print ('Decoded the get_temp cmd.')
temp_C = read_sensor()
print ("function returned temp is : " + temp_C)
c.send(str(temp_C))
print ("Sent to client : " +str(temp_C) + " Degrees C. ")

c.close
[/CODE]

Solved the issue..
sockets were not being closed.

At the very bottom of the code posted you will see:

c.close
vs
c.close()

Next problem is to learn how to post code blocks properly

Cheers and happy new year to all,

I think you've posted the code blocks properly. However, the first few posts from a new member are moderated. Then system also suppresses formatting (like code blocks), so once moderation is removed if you go back and view those posts then they'll magically appear to be fine.
