Error with connection after linux OS update (NED: cisco-apicdc-id)

[Ben Kelly]

I'm seeing the error below when trying to perform a sync-from on a APIC (NED: cisco-apicdc-id):-

admin@ncs# devices device svlngen4-fab1-apic1 sync-from

result false

info Failed to connect to device svlngen4-fab1-apic1: connection refused: INSTANCE

admin@ncs# devices device svlngen4-fab1-apic1 sync-from

result false

info Failed to connect to device svlngen4-fab1-apic1: connection refused: Could not initialize class org.apache.http.conn.ssl.SSLConnectionSocketFactory

I recently did an OS update (ubuntu), so suspect that's the likely culprit.

We recently saw a problem with some of the NEDs. The problem is that JAR files are put in the shared-jar directory, for apic this was commons-xxx.jar and httpxxx.jar. These should be in the private-jar directories of NEDs. This should be fixed in the latest APIC NED.

Please also check your other NEDs, if you have another NED with wrongly places jars, they can affect the APIC NED and give the problem above.

In general, the only jar in the shared-jar should be XXX-ns.jar, i.e. the generated namespace jar for the packet/NED itself.

I checked my the APIC NED and those file are in the private-jar directory, so that's not the cause of the issue.

Let me know if you need any logs/trace captures.

What about the other NEDs?

I've got the Cisco ASA NED setup on that system and I've verified that it's working fine
