[APP] Buienradar faulty DNS-queries

bartdiaz

Hi Buienradar-app-maker,

Thanks for this app, but checking my logs I found something odd:

My DNS-server logs a lot of queries from the Buienradar-app trying to find the domain gpsgadget.buienradar.nl, but somehow added the DHCP-suffix to this request, so it will end up sending a query containing gpsgadget.buienradar.nl.thuis.local which -ofcourse- can't be resolved by the public DNS-servers. After this query it fires some new DNS-requests containing the right DNS-name, gpsgadget.buienradar.nl

Maybe fixing this will make the app react quicker? Just a tip, hope this is useful :-)

Oct 24 18:50:35 dnsmasq[2122]: query[A] gpsgadget.buienradar.nl.thuis.local from 192.168.xxx.xxx
Oct 24 18:50:35 dnsmasq[2122]: query[AAAA] gpsgadget.buienradar.nl.thuis.local from 192.168.xxx.xxx

btw: I'm using Buienradar app version 2.1.2

Thanks for finding the issue but bugs needs to be reported at Github so Athom can do something with them

You'd better file a bug-report on the app:https://github.com/athombv/nl.buienradar
But I don't think it's the apps fault:
https://github.com/athombv/nl.buienradar/blob/master/node_modules/buienradar/lib/buienradar.js#L111
Three URL's a queried:
https://github.com/athombv/nl.buienradar/blob/master/node_modules/buienradar/lib/buienradar.js#L94
so looks like your DNS first looks on the internal network?

Weird! This is the only domain where my DHCP-suffix is added, that's why I thought it's the app... but if it's only the three hosts mentioned in your post.. well.... it's a mystery then ;-)
thanks anyway!

Well, it’s most probably the Homey OS that tries to resolve the host with the added suffix, but it is very likely caused by the returned ‘unknown host’ (or something similar) because gpsradar.buienradar.nl doesn’t exist, so it’s still a problem in the app. Not sure how dns resolving is implemented in homey, but going trough the dns suffix list if a dns query doesn’t resolve is very common.

That sounds like a valid reason!
