Error Connecting to ODL Karaf

brfoster — Tue, 18 Oct 2016 03:23:18 GMT

I just installed the Boron release of ODL. I get an error when I try to connect to the Karaf client interface. Any pointers?

[gibson@rickenbacker bin]$ ./status

Running ...

[gibson@rickenbacker bin]$ ./client -u karaf

Logging in as karaf

Update:

I found this discussion and seems to be my same issue...

https://ask.opendaylight.org/question/1524/karaf-client-failes-to-connect-to-a-server-under-linux/

Just like this person, I can SSH connect to the karaf client (see below). However, the client script still fails with "Authentication failed". I didn't have this issue with the previous "Beryllium" release.

[gibson@rickenbacker bin]$ ssh -p 8101 -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no karaf@localhost

I am running the Boron release and do not see this issue. What happens when you start karaf initially? For comparison, here is what I get:

---

ECKELCU-M-H15L:bin eckelcu$ ls

And then from another window I try to connect to karaf:

I am also curious as to which version of Java you are using:

---

ECKELCU-M-H15L:bin eckelcu$ java -version

java version "1.8.0_77"

Java(TM) SE Runtime Environment (build 1.8.0_77-b03)

Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode)

Re: Error Connecting to ODL Karaf

Well, it turned out the Java version was the issue!

I was originally using the OpenJDK...

$ java -version

openjdk version "1.8.0_101"

OpenJDK Runtime Environment (build 1.8.0_101-b13)

OpenJDK 64-Bit Server VM (build 25.101-b13, mixed mode)

Then I downloaded and installed the Oracle Java SE...

$ java -version

java version "1.8.0_111"

Java(TM) SE Runtime Environment (build 1.8.0_111-b14)

Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)

Now everything works including DLUX (which was also broken before).

Previously, OpenJDK 1.7 worked with my Beryllium release. When I updated to OpenJDK 1.8 for Boron it fails.

Great, glad that did the trick.
