[jitsi-users] Fwd: default settings - ever questioned...?!


#1

Hey Chris,
Apologies for the delay. Comments inline.

No worries, thanks for your answers - see comments inline, too

1.: !!Backup Resolver

This is quite inaccurate.

1. The backup resolver only kicks in if your primary DNS server is
misbehaving. If you have a valid DNS then queries to 8.8.8.8 would
never be sent.

What about the "Enable paralles DNS resolving" ?

As I said, parallel DNS resolving will _only_ kick in if your DNS server does not work.

2. Such queries are only made when you are connecting to a specific
account. Resolution for the actual addresses you are calling is
handled by the server.

So still, practically every time I start up my computer, Google get's my
ping...?

No. They don't. Their DNS server only receives a query when your DNS server is not working while you are trying to connect to your SIP/XMPP account.

On the whole we are currently satisfied with the compromise that we
get with 8.8.8.8 so we are unlikely to change this in the near future.

Sorry to nag, but what would be the issue or potential issue in changing
the entries to the ones mentioned?

The issues is that I don't see how this solves anything. Note that the list you pasted in your mail:

http://www.wikileaks.org/wiki/Alternative_DNS

That list also contains Google's 8.8.8.8.

So all in all I see two problems with changing:

1. I don't see how we reasonably determine whether the entity we go for satisfies the trust constraints you describe. In other words: why are the others better than Google? I don't see how we could objectively do that.

2. We need to make sure that they provide comparable reliability and speed in all kinds of the world. I don't currently know of a Jitsi contributor with enough spare time to perform such an evaluation.

Cheers,
Emil

I think every programs should default to go with the system's network configuration.
About every internet connected computer needs properly configured name resolution.

Please only ever do additional or different lookups if a savvy user explicitly configures this.
At best, trying to be "more inteligent than the user" here will make networking appear working
but not working (unreliably) on the computer, and is just asking for confusion on everyone.

Thanks for bringing these topics up!

That is what we do. Reading from all the questions about the parallel resolver, I think nobody actually understands what it does despite Emils good explanations.
