<div class="markdown_content"><p>Hello,<br/> I did kernel update as described by Edwin <br/> l <a class="" href="http://forum.codesys.com/viewtopic.php?f=26&amp;t=5652&amp;start=30&amp;p=15463&amp;lan=en" rel="nofollow">viewtopic.php?f=26&amp;t=5652&amp;start=30#p15463</a> l <br/> I have tried kernel 4.4.14-bone-rt-r11, tried 4.9.13-bone-rt-r4<br/> <a class="" href="https://www.rcn-ee.com/deb/jessie-armhf/" rel="nofollow">https://www.rcn-ee.com/deb/jessie-armhf/</a></p> <p>also tried 4.4.52-ti-rt-r91<br/> <a class="" href="https://github.com/beagleboard/linux/commits?author=RobertCNelson" rel="nofollow">https://github.com/beagleboard/linux/co ... ertCNelson</a></p> <p>Every time when I update to RT kernel I loose SSH access to BBB. <br/> In case of problem with SSH, BBB FAQ says:<br/> Delete the file called "dropbear_rsa_host_key" in the location of /etc/dropbear/.<br/> Then you need run the command '/etc/init.d/dropbear start'. </p> <p>After update to RT kernel directory /etc/dropbear/ does not exist and no command /etc/init.d/dropbear</p> <p>Any suggestions how to activate SSH?</p> <p>Thanks</p></div>
