Weird incoming connections in LOG window ?

Post by tontze »

Do i need to be worried when i see "incoming connection from xx.xx.xx.xx" from unknown ip´s for me ?

If i browser to the addresses, there is like d-link sharecenter, which i dont own(whos is it then ?), and Any time & Any where ip surveillance login page, which i dont know either ...

Are these my neighbour´s wifi devices maybe ?

Is your Domoticz installation reachable from the outside?
What you probably see are 'robots' trying to connect on port 8080, because this is published.

Advice:
- Only publish Domoticz to the outside on https (443)
- If publish Domoticz on http, don't use port 8080 but choose other and redirect to correct internal address
- Use Firewall
- Optional: use Fail2Ban

I have a Vera Edge on the LAN the insists upon connecting with my Domoticz Pi. I have no clue what that's about. I'm ignoring it for now but it is... odd.

I have 4g modem which have firewall in it. As far as i know, these connections started at same time when i added mi light ibox to my home network .. Ptopably this doesnt have anything to do with this but ..

I have dyndns in use tho, and have forwarded port 8080 to intranet, need to change this and see what happens.

Hi, some more information..

As i cancelled dyndns, it didnt have effect on incoming connections. I had a feeling that this all started when i bought MiLight bridge and some bulbs..

Why do MiLight bridge have this in settings:

It can be changed in AP settings :
