Nitrogen Mdsal northbound server is slow to accept SSH connections

Bug Resolved Won't Do Unassigned Vratko Polak Mon, 21 Aug 2017 12:52:48 +0000 Wed, 5 Sep 2018 13:19:18 +0000 Wed, 5 Sep 2018 13:19:18 +0000 3.0.2 General 0 2 <p>Yeah, this seems like performance regression in setting up SSH connection to NETCONF northbound servers in some cases. This was possibly introduced by bumping crypto libraries to newer versions or tweaking some crypto settings.</p> <p>Updating NETCONF user guide with this regression:<br/> <a href="https://git.opendaylight.org/gerrit/#/c/62664/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/62664/</a></p> <p>This causes the large part of NETCONF MDSAL suite to be unusable, since setting up the SSH connection to MDSAL northbound is its first step. Increasing timeout to 60 seconds so the suite can connect to MDSAL northbound and perform its other tests.<br/> <a href="https://git.opendaylight.org/gerrit/#/c/62665/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/62665/</a></p> <p>moved to ODL parent project</p> <p>The loop-back connection is no longer used and this only happens on first startup.</p> Development External issue ID 9020 External issue URL Issue Type Rank 0|i023dr:
