style="font-family: Helvetica,Arial,sans-serif;">Hi,<br><br>I've been
using Dropbear for many years to establish tunnels to a relay server. I
recently updated my Linux server which upgraded Dropbear from 2015.67
to
2016.74. Now all connections to the server drop after the idle_timeout
period set by the -I parameter. All clients use dbclient and initiate
the tunnel with a -K keep-alive value set to about <span
__postbox-detected-content="__postbox-detected-date"
class="__postbox-detected-content __postbox-detected-date"
style="display: inline; font-size: inherit; padding: 0pt;">1/3 the</span>
idle_timeout,
which in 2015.67 (and 2013.60 before that) would keep the tunnel alive,
even if unused, until manually killed. <br><br>dropbear server
parameters: <br> dropbear -p <span
__postbox-detected-content="__postbox-detected-date"
class="__postbox-detected-content __postbox-detected-date"
style="display: inline; font-size: inherit; padding: 0pt;">1234 -w</span>
-a -I 650<br><br>dbclient call: <br>
dbclient user@server -p 1234 -R 54321:localhost:2345 -K 200 -g -f <span
__postbox-detected-content="__postbox-detected-date"
class="__postbox-detected-content __postbox-detected-date"
style="display: inline; font-size: inherit; padding: 0pt;">-N</span> -i
~/.ssh/id_rsa<br><br><br>I don't see anything in the release notes
that
would seem to affect these setting. What am I missing? Unfortunately
there is no simple downgrade of Dropbear in my server's package
manager; I can
build a downrev if necessary but hope to avoid that if this is just a
subtle change in the parameter handling.<br><br>Thanks!</span></div>
