how can we create a permanent connection between server and client?
You can't create a permanent connection. Once either system undergoes a shutdown the connection will be broken. Why would you want a permanent connection? Just set the server to constantly listen for new connections and have the clients connect as needed.
I want to create a connection which look for new data from a folder and when new data comes send it to serve and should not close automatically. And it is a images data.
A better method would be to have a script that watches that folder and opens connections to the server when new data enters that folder. That will remove the problem of having a constantly open connection and the server would only have to worry about listening for any new connections.
i run the code but it is not working
@Sirernest what was the error or the output? Have you try to run it with Python 2.7 or higher? Are you using Windows, Linux which OS?
Provide me more infos and may i or somEbody else is able here to help you out. :)
Check this out. File tranfer via socket. It is the easiest code https://youtu.be/SZyd7xGTBkw
Is this OS is linux?
@kimakuma no this is on Windows but i remember that is running also in Linux maybe with a few changes.
@hightTest nice thank you
The file transfer for large files is slow as hell of course if we can make it faster it could be good. Please check it guys
where does it save the file ?
Does this work on python 3.8? I can't quite seem to get it working (even when fixing the print statements).
On the client side he doesn't need to call f.close() but on the server side he needs it.
