During update, the Karaf related configuration was removed from File
<Site configuration> refers to the openHAB Documentation File Locations, in this case for Linux.
If the relevant configuration is added again:
org.apache.karaf.shell:sshHost = 0.0.0.0
remote access to the Karaf console is working again.
I’ve not had any issues with the Karaf console after upgrading to 2.3.0-SNAPSHOT.
My line is current disabled:
#org.apache.karaf.shell:sshHost = 0.0.0.0
But I can connect to the console :9001 without any issues.
I would have suggested checking the IP address, in case DHCP gave it something different, but since you said it works after adding the config setting, that doesn’t sound like it’s the cause.
