Re: [Help-gnunet] gnunet-dns interface

[Christian Grothoff]

Dear Calvin,

SVN HEAD is currently having some connectivity issues, which are my
current priority to address. I don't know which version you're using,
but if it is SVN HEAD it might do to wait a few days and update
(assuming I manage to find & fix the issue(s), it is top on my list though).

The gnunet-dns virtual interface is used as one way how GNUnet can
intercept DNS queries to pass them to the GNU Name System.  So depending
on how you configured your system, it should be normal but not cause any
trouble, as only DNS traffic should be passed there anyway.  GNUnet's
own traffic (DNS and otherwise) will go through your normal network
interfaces.

Now, you should probably also see a gnunet-vpn interface for the GNUnet
VPN, unless you simply didn't configure that service to run (but in that
case I wonder why the DNS interceptor is running).

Finally, you should be able to just stop your peer and use
"gnunet-transport -t" or gnunet-setup (if you installed gnunet-gtk) to
test your network configuration.  If that works, most likely bugs are to
blame and not your configuration.

Happy hacking!

Christian
