Bug#602764: ekiga: listens to wrong ip

[David Fries]

Package: ekiga
Version: 3.2.7-2
Severity: important
Tags: patch


Ekiga/opal initially listens to each individual ip:port on the system.
When a call is started it is picking the first non-localhost ip
address and binding to that one, which is a very bad guess as to which
IP the remote system is going to send RPT packets to.  This means if
the system has multiple ip addresses it either works, or all the
incoming UDP packets get rejected with an ICMP error because ekiga is
listening to a different ip and port.

Capture ekiga -d 4, and search for "Initial interface list:" for the
interface order.

Also, on startup not only does ekiga bind to each ip address it sends
out the initial subscribe SIP requests from each to the remote server.
In my case only one ip address is on the network which has a default
route, the other networks are in the 192.168.0.0 and 172.20.0.0
ranges, which is causing packets to be routed to internet with local
non-routable ip addresses.  If it isn't going to look at the routing
tables to figure out which local ip addresses can get to the route
system, it should just call connect, let the kernel assign the local
ip address, and read what that local ip address is.

Until some more sane algorithm is picked, here is a hack listen to all
of them.  I'm not going to call this the right solution, but it does
let me hear the other end.
