Open Karaf console on Pi via ssh?

[pahansen (Paul Hansen)]

When I have oh2 running from a headless Pi3 installed via apt-get or dpkg -i , how do I use the karaf console? I ssh into the pi to do all my maintenance work, and use Designer for my configuration edits, but have no idea how to actually use the karaf console to get better logging, or delete caches, etc.

If you have a shell, you can

sudo /usr/share/openhab2/runtime/karaf/bin/client

to get the karaf console.

Alternativly do

 ssh openhab@localhost -p 8101

with pw: habopen

Important: When logging in the first time, give it 2 or 3 minutes, see here

ssh openhab@localhost -p 8101

How connect to it without password, where I must put my id_rsa file?

Just for tracking, public key authentication is also available:

Karaf console

You need to add public key (most likely .ssh/id_rsa.pub) to authorized keys in Karaf. You can edit ${OPENHAB_HOME}/userdata/etc/keys.properties. This is flat property file where key is username and value is public key used for authentication. Public key must be without perfix (ssh-rsa) and comment at the end, just one long string. After comma you need to assign group, so whole line looks like this openhab=sshkey,_g_:admingroup.
