port 443 already in use (on another IP adress...)

[lug-gh]

You can set the Admin Adapter to a certain IP, but it doesn't seem to check if the port is free on this IP, but if any IP is using port 443.

The admin instance is bound to 10.0.0.10 and there is also an nginx server running on the host which is bound to 10.0.0.11:443.

Thus, the port that the admin instance wants to use is not occupied, but it still complains about this as an error and does not start. I always have to stop nginx first to then be able to start iobroker.

This is what it looks like when I start iobroker first, then nginx.

netstat -tuln | grep ':443' 
tcp        0      0 10.0.0.11:443        0.0.0.0:*               LISTEN     (nginx)
tcp        0      0 10.0.0.10:443       0.0.0.0:*               LISTEN	(iobroker)

2022-08-27 11:25:20.922  - error: admin.0 (236362) port 443 already in use
2022-08-27 11:25:20.924  - info: admin.0 (236362) Terminated (ADAPTER_REQUESTED_TERMINATION): port 443 already in use

2022-08-27 11:25:24.974  - error: host.iobroker instance system.adapter.admin.0 terminated by request of the instance itself and will not be restarted, before user restarts it.

I don't see any logical reason for this, so I think it's a bug when checking port usage.

[Apollon77]

right, there is no host rovided for the port check ... so providing the settings.bind (if not 0.0.0.0) to https://github.com/ioBroker/ioBroker.admin/blob/master/lib/web.js#L1031 as additional second parameter in that call should fix that ... could you try that out?

Sorry, I don't understand what to do, I'm no developer :)

[Apollon77]

Ok, then for you to try...

• open /opt/iobroker/node_modules/iobroker.admin/lib/web.js
• change line 1031 from https://github.com/ioBroker/ioBroker.admin/blob/master/lib/web.js#L1031 to

                    adapter.getPort(settings.port, (!settings.bind || settings.bind === '0.0.0.0') ? undefined : settings.bind || undefined, port => {

The line number above refers to the very latest Beta Admin version, so check the content please

Restart admin, try again

[lug-gh]

Thanks! Looks good, if the port is not used I can start the admin adapter, and if it's occupied I cannot.

[Apollon77]

Ok,then I will bring this in a next update

[Apollon77]

Other adapters that could benefit:

ioBroker.contact/main.js: adapter.getPort(settings.port, (port) => { ioBroker.egigeozone/main.js: adapter.getPort(settings.port, function (port) { ioBroker.geofency/main.js: adapter.getPort(settings.port, port => { ioBroker.harmony/harmony.js: adapter.getPort(61991, port => { ioBroker.lovelace/main.js: adapter.getPort(server.settings.port, port => { ioBroker.megad/main.js: adapter.getPort(adapter.config.port, function (port) { ioBroker.megadd/main.js: adapter.getPort(adapter.config.port, function (port) { ioBroker.megaesp/main.js: adapter.getPort(adapter.config.port, function (port) { ioBroker.simple-api/main.js: adapter.getPort(settings.port, port => { ioBroker.socketio/main.js: adapter.getPort(settings.port, async port => { ioBroker.swagger/main.js: adapter.getPort(settings.port, port => { ioBroker.telegram/main.js: adapter.getPort(adapter.config.port, port => { ioBroker.template-rest/main.js: adapter.getPort(settings.port, function (port) { ioBroker.web/main.js: adapter.getPort(settings.port, port => { ioBroker.wetty/main.js: adapter.getPort(settings.port, function (port) { ioBroker.xterm/main.js: adapter.getPort(settings.port, async port => { iobroker.paw/main.js: adapter.getPort(adapter.config.port, function (port) { iobroker.terminal/main.js: adapter.getPort(settings.port, function (port) { ioBroker.admin/lib/web.js: adapter.getPort(settings.port, port => { ioBroker.tronwallets/lib/web.js: adapter.getPort(settings.port, port => {

[Apollon77]

Awesome!

[lug-gh]

Well, for me it seems to break the iobroker.admin instance after reboot.

iobroker status admin.0

Instance "admin.0" is running

So i create a dummy log entry to be sure where the log starts before the reboot echo "########## DUMMY NACHRICHT admin.0 - ab hier wenn port 443 beim boot NICHT belegt ist" >> /opt/iobroker/log/iobroker.current.log && reboot

wait for the reboot to be done

grep 'admin.0' /opt/iobroker/log/iobroker.current.log

and this, even if port 443 is not used!

netstat -tulpn | grep ':443:' no output, to verify: echo $?

1

to get the adapter up i have to execute this after the boot: iobroker stop admin.0 && iobroker start admin.0

The adapter "admin.0" was stopped.
The adapter "admin.0" was started.

iobroker status admin.0

Instance "admin.0" is running

[Apollon77]

If this error comes then the adapter can not bind the server to port 443 ... please try to run "iob fix" to fx pot permission issues.

Additionally: getaddrinfo EAI_AGAIN means that there are DNS issues!!

[lug-gh]

please try to run "iob fix" to fx pot permission issues

Unfortunately iob fix didn't help to fix it

there are DNS issues!!

Hmm, so my DNS server logs all requests, and all requests from my Pi were answered successfully, strange.

      Also, I'm not sure if this issue is related to this github-issue, or would that be better handled separately?

[lug-gh]

@foxriver76 the issue is still existent

[lug-gh]

extended debugging

Strange, did some more testing, even if the port 443 is not used by any other process - after a reboot of my raspberry pi, the adapter fails to start.

I see the getaddrinfo Errors, but I cannot see a reason why that happens.

Edit: to ensure these errors are not by dns, I added the dns records to /etc/hosts, then I dont get getaddrinfo errors, but

2023-08-10 21:43:03.749  - warn: admin.0 (584) Cannot check node.js versions: Error: connect ENETUNREACH 104.20.23.46:443 - Local (0.0.0.0:0)

So, iobroker want's to start before network is up?

Edit 2: Okay, it seems like the raspberrypi is the issue - well - more or less. If I disable the autostart (systemd service file), reboot the pi, and go to htop, I see a 100% CPU load for 2-3 minutes. After that drops to <10% I manually start iobroker, and that's it. So the load at boot is the issue.

[lug-gh]

❓ But, why am I getting that error message with the port already being used? Is this message displayed if the check for update/nodejs version fails, or because the check if the port is already in use runs into a timeout?

[raintonr]

I just updated from 6.4.4 to 6.8.0.

Kills admin with these messages in the log:

2023-09-03 08:11:51.288  - error: admin.0 (11549) port 443 already in use

netstat shows no processes using 443:

$ netstat -anp | grep LISTEN | grep 443

Strangely iob start admin.0 does nothing. But restart does at least try and start the instance:

$ iob start admin.0
$ iob restart admin.0
The adapter "admin.0" was started.

However, it dies again:

This is a major bug!

[Apollon77]

Please run "iob fix". Still happens? Also with newest beta version?

[raintonr]

Please run "iob fix". Still happens? Also with newest beta version?

iob fix solved this scenario for me. No beta (see version number in log above).

[mcm1957]

@raintonr Just for Info: According to log js-controller: 5.0.8. This is beta and not the newest beta :-). But likely not related to this issue

[lug-gh]

@Apollon77 should I create a new issue? It is clear that under certain circumstances, an incorrect or misleading error message is displayed. A generic error message is better than a misleading message, right?

[Apollon77]

Yes a new issue fpr better error mesagwer would be cool ... or a PR :-)
