I noticed that the ping threw an exception in the new version if the target dns name was invalid. Could that be the case?

marcus67 commented 2 years ago

Hosts with invalid DNS names which are not recognized by ping only trigger an error message in the logging output. I hope this is OK now. @vaidls : Please, monitor your logging output for a while. If these messages occur you may have to choose different host names. Thanks for reporting!

Yes. It's standard Avahi (zeroconf) domian (.local.).

Then users disconects from network, it disapeares from DNS (which is local and self hosted), entries are added/removed dinamicaly.

So, dns gives resolve error and ping does not even start as ip is not found.
