<div class="markdown_content"><p>Hi,<br/> Thanks for the advice!<br/> I'll try tomorrow and I will write immediately.<br/> Network settings work through the file /etc/network/interfaces in Debian 8.6? <br/> I thought all the network settings in Debian 8.6 (Jessie) made through the service ConnMan, and file /etc/network/interfaces is not used.</p> <p>The original post I got this from can be found here: <a class="" href="https://groups.google.com/forum/#!topic/beagleboard/yfNwIk_dWlg" rel="nofollow">https://groups.google.com/forum/#!topic ... fNwIk_dWlg</a>.<br/> Thanks to Brian Anderson for the original comment.</p></div>
