arduinomdns's Issues

Service query message sends some junk

The service query message appends some data that shouldn't be transmitted.
I will create a more thorough explanation soon.

Wrong Service type in WifiRegisterExample

The example starts out with udp as the protocol used for mDNS but when registering the service it tries to use TCP which will cause it to crash

addServiceRecord crashes in MDNS.cpp

In more than one location, space is created with something like:

char* mem = malloc( strlen( text ) );

followed by something like:

strcpy(mem, text);

This only mallocs enough memory for the number of characters in the text, but not for the terminating null, so that the strcpy writes outside the bounds of the allocated memory.

Better to do something like:

char* mem = malloc( strlen(text) + 1 ); // so that there's room for the terminating null.

Service Discovery returns garbage data

When I use one arduino to generate an MDNS service, and another arduino to listen to the service...

The service name is OK
The IP address is OK, but sometimes, it's 0.0.0.0?
The port is not the same port advertised by the arduino? Sometimes it is a random number.
The text content is arbitrary garbage

It seems like adding the service record is OK, as on my host computer, I don't have issues reading the text data,

...but the service discovery on arduino is very broken?

Include latest TrippyLighting fixes?

Hello dear developers,

I see that the trippylighting branch has a few additional commits/fixes (june-august 2017) since the last one here (april 2017). Would it be possible/necessary to include these in the arduino-libraries fork?

See: https://github.com/TrippyLighting/EthernetBonjour/commits/master

Cheers,

Brian.

Missing character

During my tests I found that a character is missing.

In my code I use:
mDNS.addServiceRecord("_ewillie._tcp", 1883, MDNSServiceTCP, "testdata");

When I look with Discovery.app ( www.tildesoft.com ), I only see the text: estdata
The first character is missing.

Please release version and tag

I am looking a way to to pin my dependencies, would this be possible to have tags in this repo ?

Eventually aligned the arduino sdk ones

Does ArduinoMDNS update its mDNS cache automaticly?

I am not that into mDNS but I read several times now that mDNS machines can update their mDNS cache automaticly.

When an mDNS client needs to resolve a host name, it sends an IP multicast query message that asks the host having that name to identify itself. That target machine then multicasts a message that includes its IP address. All machines in that subnet can then use that information to update their mDNS caches. Wikipedia

Does ArduinoMDNS library does this too or is it only possible to query for a host or a service which are both blocking operations?
