Karaf client failes to connect to a server under linux

I am trying to access an opendaylight server running on Linux in a back round process. I am running a distribution-karaf-0.2.1-Helium-SR1.

From what I understand in case you are trying to connect from the same machine all you need to do is run

./client and the connection will be done.

However all I get is :

[root@d20-srv-81-32 bin]# ./client Logging in as karaf 258 [pool-2-thread-2] WARN org.apache.sshd.client.keyverifier.AcceptAllServerKeyVerifier - Server at /0.0.0.0:8101 presented unverified key: [root@d20-srv-81-32 bin]#

When I to try to connect using a simple ssh: ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -p 8101 karaf@localhost the operation is successful.

Has any one encountered the issue?

Solution

  • in the end the issue was caused because i used the zip release of open day light helium.

    on the opendaylight download page there are two versions. one compressed as a zip and the other as tar.gz. from what i found there are system differences between them the zip is for windows and the tar for Linux.

    when i deployed the tar version on Linux the issue did not reproduce.
