Hello there, I have, using Daniel's tip, used curl from command line of my RaspberryPi. It worked OK. The same URL from ./FTPupload did NOT work, error code file attached. So Daniel can very well be correct: the URL used is not the one I programmed. Any way one can see what the program sends to the network? Debug the outgoing data. My exact version of ftpupload.c is attached. Where is the problem hiding? Nils Den 2015-08-11 kl. 19:09, skrev Daniel
