[jitsi-users] dns issue on OSX while using openVPN


#1

While using Jitsi on OSX we have discovered a potential issue/bug. The
openvpn server pushes an internal DNS server to the OS X computer, however
Jitsi is unable to resolve the DNS of the private server. I have attempted
to add entries to the hosts table as well as tested DNS resolution from the
terminal. DNS is working normally on all other applications with the
exception being Jitsi. DNS continually fails, and calls are unable to be
made when connecting to the server using only the IP address. Any
suggestions would be greatly appreciated. I have read through the log
files and verified that DNS is the culprit.
Thanks,

The hosts file is not used in Jitsi due to a limitation in dnsjava, as
mentioned multiple times on the list.

The list of DNS servers is refreshed whenever an interface comes up or goes
down. You should see something like "Reloading resolver config, default DNS
servers are: ..." in the log. If OpenVPN doesn't work with virtual
interfaces that go up or down OR somehow modifies State:/Network/Global/DNS,
we have no chance of knowing that there is a new DNS server.

What you could try is to set the parallel resolver
(Tools->Options->Advanced->DNS) to your DNS server behind the VPN and
setting a very low threshold to kick in.
