OSError [Errno 99] - python

Question

i want to execute the following simple server code:

import socket

s = socket.socket()         # Create a socket object
host = socket.gethostname() # Get local          


        

Answer 1

Try set the SO_REUSEADDR option to the socket:

s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

Answer 2

If it works using the ip address but not using hostname.

You should have something like this in your /etc/hosts mapping ip to hostname.

127.0.0.1   localhost
127.0.1.1   your_hostname_here

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Your /etc/hostname should obviously be the same as above.

Reboot and you should be able to ping your hostname successfully.

You can also use socket.gethostbyname(socket.gethostname()) to get the i.p as opposed to the hostname
