I have a simple socket server set-up to send some numbers to a client in the intranet. While testing, I stop the server.py script from terminal(CTRL+C) which later causes busy server error in Safari when I try to reach the same page.
I saw this serverfault question But the issues are:
I could not find the /etc/init.d/networking restart file. I am using Mac and this is for Linux. Also it is an overkill for every-time I test my server. At least 10 times an hour.
Inserting the option SO_REUSEADDR in the code did help Address already in use but I reckon that my server is up but is in a busy state. Using the answer here, I had edited the code to this:
host = <my machine address>
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
port = 8080
s.bind((host, port))
What changes do I make on my server to remove this error in Safari?
Safari can’t open the page "my-ip" because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait for a few minutes and then try again.
Output of lsof -i:8080, after stopping the script was
python3.7 11881 <user> 3u IPv4 <Device> 0t0 TCP <my machine address>?:http-alt (LISTEN)
I did kill 11881 and then re-run the code but got the same message in Safari.
Output of netstat -na | grep "8080" was
tcp4 0 0 <my machine address>.8080 *.* LISTEN
while the script was running and nothing when I KeyboardInterrupt it.
Firefox shows the page momentarily and then shows the error page
The connection was reset
Chrome shows an empty page only.
Update: It works in python 2.7 but not in 3.5. The difference in the code comes at:
c.send('\n')
in 2.7 and
c.send(bytes('\n'.encode('utf-8')))
in 3.5 where
c is
c, (client_host, client_port) = s.accept()
Rest is all the same.
I had accidentally commented out a line
c.recv(1000)
Where c is mentioned in the question.
I found it when I compared this to an older version of the same file.
