Internet Connection IP changed is shown, but connection did not change

[todrees1967]

Is there an existing issue for this?

• I have searched the existing open and closed issues and I checked the docs https://github.com/jokob-sk/NetAlertX/tree/main/docs

Current Behavior

I am getting constant messages (5-6 times a day) that the IP of my internet conncetion has changed. One message shows 0.0.0.0 as the IP the next one shows my "real" internet IP. This message shoudn't appear, since I have a static IP v4 using a cable connection (Vodafone, Germany) and the connection is not disconnected usually.

Seems the problem is related to that entry in the logs:

11:25:50 [INTRNT] DIG result : ;; communications error to 208.67.222.222#53: timed out

Why is the connection to the opendns Resolver timing out? Can I configure any other/different DNS server?

Expected Behavior

Not getting a timeout from OpenDNS when checking the internet IP.

Steps To Reproduce

Hi There,

Thanks a lot for this much detail.

You should be able to change the DNS server by adjusting the setting INTRNT_DIG_GET_IP_ARG:

[todrees1967]

Hi,

if I change the dns, I am no longer getting the right response, the command seems to be

dig -4 myip.opendns.com @resolver1.opendns.com

but if I am doing

dig -4 myip.opendns.com @dns.google.com

I not getting the right answer. Can you help me with that?

[todrees1967]

After checking https://askubuntu.com/questions/95910/command-for-determining-my-public-ip, it seems, that this dig command can be only used with OpenDNS to retrieve the IP. There are other options, but they are using a different command.

Any suggestions?

[jokob-sk]

Hi there,

Could you please try this setting?

@ns1.google.com -t txt o-o.myaddr.l.google.com

[todrees1967]

Hi there,

also with a different DNS provider the problem remains the same. I tried this command many times directly on the same linux server using the shell and I never got a problem. Is there anyway to take a more detailed trace on executing the command?

[jokob-sk]

Hi there,

Can you post the logs with the google DNS in place? I'm starting to think that if 2 different DNS server configs produce the same result then potentially the internet is actually down during the scan. Would that be possible?

[todrees1967]

Hi there,

the error message reimains the same:

10:45:12 [INTRNT] In script
10:45:12 [INTRNT] INTRNT_DIG_GET_IP_ARG: -4 @ns1.google.com -t txt o-o.myaddr.l.google.com
10:45:12 [INTRNT] - Retrieving Internet IP
10:45:17 [INTRNT] DIG result : ;; communications error to 216.239.32.10#53: timed out
"xx.yyy.zzz.xx"
10:45:17 [INTRNT] Current internet_IP : 0.0.0.0

I know for sure, that the internet is not down. I am working from homeoffice, if at the that time the connection was down, I would habe recognized it.

NetAlertx runs on Docker on an Ubuntu 22 LTS Server, that is connected with LAN to the router. The server itself has a lot power, i7with 32 GM RAM and SSD on NVME.

I have create a script in parallel that runs on the Ubuntu host itself, using the same command. And I have to admit, that sometimes I am also getting a timeout here.

So far I have no idea, what causese htis problem. Since the time of occurences really vary, it might be only a very little temporary problem. At least my router does not show reconnect in this log.

What do you think of sending the DIG command three times in a row and only if all three commands are failing having a corresponding messsage in the log?

[jokob-sk]

This should be available in the next release. Please have a look at the netalertx-dev docker image, in about 15 minutes (or after the last action finishes) from now.

Make sure you refresh your browser cache - and click the 🔄 refresh button in the top right corner.

It would be great if you could test this (backup everything first or use a new container) on your end by switching to the above image and letting me know if the issue was resolved.

Thanks in advance,
j

Hi there, sorry for coming back that late, i was on vacation and some time off. I just updated the image and will come back here, if this happens again. Thanks for fixing this.
