openHAB installed, started, but no webinterface

Setup, Configuration and Use Installation
1
  • Platform information:
    • Hardware: Intel® Atom™ CPU D410 @ 1.66GHz, 2 cores
    • OS: debian 8
    • Java Runtime Environment: 8
    • openHAB version: 2.4
  • Issue of the topic: I’m new to openHAB and recently installed openHABian on my debian 8. I had some issues with python and java when installing, but these seem to have been fixed.
    When I however want to access the webviewer on port 8080, I don’t get a web connection.

Here is some output that demonstrates current configuration:

netstat -anp | grep 8080

The installation is completely default, so no ports have been changed or whatsoever. I however see from the netstat output that no java service seems to be listening on port 8080.

I had another service running which redirected traffic from port 8080 to 8443, so I killed that service. I tried disabling the host-based firewall rules completely.

Can somebody shed some light on this?

2

Is this the very first time of starting up?

It can take… A VERY long time to self configure.

Refresh the web browser occasionally

You’ll first see a Jetty error

Then the openHAB2 start page will begin to build

4

This is indeed the first time.

I re-installed yesterday and still don’t see a web page. It shouldn’t take that long?

5

Yeah, a day is probably too long.

Have you tried the https port / URL ?

What does…

systemctl status openhab2

give you?

I’m out of ideas now :frowning_face:

6

Check the log file for any exceptions and try to change the port. Seems like the java process cannot open that specific port on your host.

7

HTTPS port (8443) provides the same result.

systemctl status openhab2

If I then do,

Nothing comes back, same with 8433

In /etc/default/openhab2, I set:

I really am shooting in the dark here, as I’m very much a Velbus hardware chap, who is still learning openHAB2. (98% Velbus knowledge, 2% coding / software)

May I ask if you’re looking at the web server from the same machine, or over a network?

(I had a client who had terrible network issues that were blocking all kinds of things)

10

Much appreciated though!

I’m connecting through my internal network. An iptables rule has been made for 8080 and to be sure there is no iptables issue, I flushed the ruleset completely.

I however do see a (new?) error message in the log:

journalctl -u openhab2.service -b

I didn’t see this before, is this something of a known issue (with Eclipse?)?

11

After some digging this seems to be a known issue in Eclipse, removing specific files (TableLock and fileTable) should fix this.

So I searched these:

locate -r eclipse | grep Table

/var/lib/openhab2/cache/org.eclipse.core.runtime/.manager/.fileTableLock
/var/lib/openhab2/cache/org.eclipse.osgi/.manager/.fileTable.3
/var/lib/openhab2/cache/org.eclipse.osgi/.manager/.fileTable.4
/var/lib/openhab2/cache/org.eclipse.osgi/.manager/.fileTableLock

Removed these files and restarted openhab.
Still no service listening on port 8080 (or another port that I tried).

12

Solved, I completely de-installed and now installed through linux apt-get method instead of hassle free openHabian and worked instantly…
