           Summary: Internet Call keeps trying a non-existing IP
           Product: Communication
           Version: unspecified
          Platform: N800
        OS/Version: Maemo
            Status: UNCONFIRMED
          Severity: normal
          Priority: Medium
         Component: Internet Call
        AssignedTo: rtcomm at maemo.org
        ReportedBy: parejkoj at speakeasy.net
         QAContact: internet-call-bugs at maemo.org


SOFTWARE VERSION:
4.2008.30-2

I recently updated my N800 to Diablo, but then was unable to use the Internet
Call function (which runs telepathy, correct?), because the tablet was giving
my firewall grief.  After some digging, I found that the tablet was repeatedly
trying to connect to a non-existent IP (192.168.1.66) on a random,
high-numbered UDP port (>49000) and my Linux firewall was blocking all such
connections (doing exactly as I told it to do!).  I've changed the "drop" rule
to "reject" and calls now go through, but I'm wondering why the tablet is
trying to access that IP.

I can provide a tcpdump of an attempted internet call or more details of my
home network configuration, which is roughly as follows:

           /-> wireless (192.168.3.x) -> N800
firewall (192.168.1.1)
           \-> wired (192.168.1.x) -> desktop

This happens every time I attempt a call with the tablet, and happened
immediately after reflashing and installing the OS2008 update with via SSU, so
it isn't due to some other piece of software.  "lsof -i" during an attempted
Internet Call confirms that "telepathy" is the process that is poking at the
above IP.

I would not have figured this out if it weren't for the fact that my firewall
(an Ultrasparc-60 running Debian) apparently briefly freezes up due to the
large number of DENYs it has to issue, which I suspect is the real reason the
Internet Calls don't go through: the route dies.

This is very odd behavior.
