Hello!
I made flask server on python which generate links with /<mac_address>.cfg URL path for each telephone in our organization. Configuration files are also generating for each telephone.

If i take new telephone from box. Telephone getting autoprovision server URL from DHCP server and updating all configuration. ALL GOOD.

Then i made some changes in configuration on telephone and started waiting until telephone will make request on autoprovision server. Ok! i see request, but configuration didn't changed back....

Code:

168.53.30 - - [20/Feb/2021 08:33:20] "GET /configs/805ec0ae9ab6.boot HTTP/1.1" 404 -

168.53.30 - - [20/Feb/2021 08:33:20] "GET /configs/y000000000000.boot HTTP/1.1" 404 -

168.53.30 - - [20/Feb/2021 08:33:20] "GET /configs/y000000000052.cfg HTTP/1.1" 404 -

168.53.30 - - [20/Feb/2021 08:33:20] "GET /configs/805ec0ae9ab6.cfg HTTP/1.1" 200 -

Please help to find what im doing wrong?

Ok. i founded problem and resolved it!

Code:

<134>Feb 20 09:17:38 ATP [1277]: ATP <6+info  > need_cmp_md5=1

<134>Feb 20 09:17:38 ATP [1277]: ATP <6+info  > cfg md5 same!

All problem was because md5 check... because telephone didn't want to update configuration if last downloaded file and new downloaded file have same md5.

I have made work around method to make md5 different. Every request from telephone i add in config file in the end date and time.
