NM gets it wrong

[Tim Niemueller <tim niemueller de>]

Hi guys.

I have been doing some work on OpenVPN. The good news: The new modes
(shared key and password) are working in my test setup. Finished some of
the features requested/bugs reported.

I still can't fix the problem that has already been described earlier
(by j bootlab): If the VPN connection is established, OpenVPN assigns
two IPs. From the clients point of view the remote address is the
server, the local is the own IP. Both are transmitted via OpenVPN.

In my test case the server has address 10.9.0.5, the client 10.9.0.6. So
the output should look like:

tim evilgenius:[~/dev/NetworkManager]# ifconfig tun0
tun0      Link encap:UNSPEC  Hardware Adresse [...]
          inet addr:10.9.0.6  P-t-P:10.9.0.5  Maske:255.255.255.255
[...]

it looks like this right after the connection has been started! And
OpenVPN gives this information to the helper. But as soon as this
information is sent to NM the output looks like:

tim evilgenius:[~/dev/NetworkManager]# ifconfig tun0
tun0      Link encap:UNSPEC  Hardware Adresse [...]
          inet Adresse:10.9.0.6  P-z-P:10.9.0.6  Maske:255.255.255.255
[...]

Not the inet addr and P-t-p addresses, they are the same! I have
double-checked. The OpenVPN service sends the correct information to NM.
I added output to the openvpn service and used dbus-monitor to see what
actually gets send.
I'm not even sure if this is a problem. A route to the remote address is
correctly set. In the example given this looks like:
tim evilgenius:[~/dev]# route -n
Kernel IP Routentabelle
Ziel            Router          Genmask         Flags Metric Ref    Use
Iface
10.9.0.5        192.168.4.1     255.255.255.255 UGH   0      0        0 ath0
192.168.4.0     0.0.0.0         255.255.255.0   U     0      0        0 ath0
169.254.0.0     0.0.0.0         255.255.0.0     U     0      0        0 lo
0.0.0.0         0.0.0.0         0.0.0.0         U     0      0        0 tun0

And although I cannot ping the remote IP I'm still able to route traffic
over that connection.

Does anybody have an idea where this gets messed up and why and where NM
sets the P-t-P address or what I did so horribly wrong and actuall _if_
this is a problem. Did you do any more tests j?


Another thing that I noticed that if you edit two VPN connections of
different VPN type (vpnc and openvpn) one after another the second time
it will show you both widgets stacked on one screen. Is that a problem
that I introduced or something that is not been seen yet since there has
been only one VPN service till now?
