Strange chineese sites in OH2 logs

Add-ons Bindings
1

I have ESP12 with SIM800 configured in items (http binding), but not connected to power now.
Looks like http binding try connect to strange sites.
I dont understand what is this:

Can you post your .items entries for the ESP12?

Maybe the ESP12 is sending to OH2 these URLs

3 
//######################## GSM ############################## 
Number	ESP_GSM_Uptime  "Uptime"  (gStore)  { mqtt="<[oh2agdisk:/esp/gsm/sensors/uptime:state:default]" }
Number	ESP_GSM_Memory  "Freemem"  	{ mqtt="<[oh2agdisk:/esp/gsm/sensors/freemem:state:default]" }
Switch	ESP_GSM_Ping  "GSM в сети [MAP(on_is_da.map):%s]"  <network>  (gPing)  {channel="network:device:192_168_1_12:online" }

most likely this one is causing the “trouble”.
I assume that the response that this http call is making has these URLs included in it.

What happens if you use a browser and access this specific URL?

http://192.168.1.12/simread?clear=1

Did you reprogram your ESP12 with a new sketch or you are using it with whatever was loaded to it?

5

No, my ESP12 is turned off all this time.

OH2 could have received the string as a response from a previous connection to the ESP12
Try to turn it on and check the output of the http request (http://192.168.1.12/simread?clear=1)

This error (StringIndexOutOfBoundsException) is usually associated with a wrongly formatted string that is included in a response to a call.

Try to check the following from Karaf console also:

smarthome:items list |grep ESP_GSM_Simread

and check the “State=”

7 

openhab> smarthome:items list |grep ESP_GSM_Simread
ESP_GSM_Simread (Type=StringItem, State=NULL, Label=GSM log, Category=null)
openhab>

I never turn on ESP12 with OH2, i moved items file from OH1 to OH2, since that time ESP was turned off.

8

Have you tried log:set TRACE org.openhab.binding.http in the console?

9

This is incoming request from Internet which has nothing to do with your bindings. I suppose your openhab is exposed to internet and it is just being scanned. Attacker just uses bogus host name while using your valid remote IP address.

Why I have the same problem ? my OH is exposed but behind a VPN
