Packet looping back to...

[Oliver Belikan]

Hi,

I use tinc1.0.3 with a WinXP SP2 box to connect to a linux-server. After
startup of tincd the connection from XP-box (Oliver) is established but
i receive a routing error:

"Cannot route packet from Oliver (MYSELF): unknown IPv4 destination
address 224.0.0.22" and
"Packet looping back to Oliver (MYSELF)!"

I?ve no idea where the address 224.0.0.22 comes from. My hosts file is:

/hosts/Oliver
Subnet = 192.168.4.0/24
-----BEGIN RSA PUBLIC KEY.................

In TAP-Device i use
IP: 192.168.4.1
Mask: 255.255.255.0


I tried to change "Subnet = 192.168.4.0/32" in hosts/Oliver, but
received no other result.

Any ideas what is wrong ?
Thank you.

The 224.0.0.22 thing is Windows trying doing some kind of autodetection

You should change it to Subnet = 192.168.4.1/32.

Ok thank you.
I changed /host/Oliver to 192.168.4.1/32 and as a result the "Packet
looping back..." seems to be gone, but the entry "Cannot route packet
from Oliver (MYSELF): unknown IPv4 destination address 192.168.4.255" is
still to see in the logfile.

No ping, no ssh is possible from the Win XP box. Needs Win XP some
special running (remote)-services ?

Again my Files:
\hosts\Oliver
Subnet = 192.168.4.1/32
Address = 192.168.4.1
-----BEGIN RSA PUBLIC KEY-----
...
-----END RSA PUBLIC KEY-----


\hosts\Server
Subnet = 192.168.10.0/24
Address = 217.24.201.66
-----BEGIN RSA PUBLIC KEY-----
...
-----END RSA PUBLIC KEY-----

IP TapWin32-Adapter: 192.168.4.1
Subnetmask: 255.255.255.0



Win XP SP2 Firwall is temporary switched off.

I?ve no idea where the address 224.0.0.22 comes from. My hosts file

The 224.0.0.22 thing is Windows trying doing some kind of autodetection

I tried to change "Subnet = 192.168.4.0/32" in hosts/Oliver, but
received no other result.

You should change it to Subnet = 192.168.4.1/32.

192.168.4.255 is caused, again, by Windows trying to autodetect
whatever.

\hosts\Oliver
Subnet = 192.168.4.1/32
Address = 192.168.4.1

Remove that Address line or change it to the public IP address of
Oliver.

\hosts\Server
Subnet = 192.168.10.0/24
IP TapWin32-Adapter: 192.168.4.1
Subnetmask: 255.255.255.0

You should change the subnet mask to 255.255.0.0.
