tinc - Mar 2014 - Tons of "Failed to decrypt and verify packet"

Hi all,

I tried Tinc 1.1 from git on 4 nodes, each one in a datacenter.

They were able to ping each other, etc... but I had problem with
multicast, nothing seemed to pass (all is OK with Tinc 1.0.23).

I checked logs and on every nodes I have a lot of:

Failed to decrypt and verify packet

And

Error while decrypting: error:00000000:lib(0):func(0):reason(0)


So I get back to 1.0.23 which works fine...

What could be the problem?

All nodes are 2.6.32, is there any problem with it ?

Thank you :)

Florent

Are you running tinc on windows? I found this bug too.
You need add "ExperimentalProtocol = no" to tinc.conf on all nodes.

There is no problem on both unix/linux nodes.

Just an email to confirm the bug.

I was doing tests in a virtual network using network namespaces, with
ExperimentalProtocol=yes
So obsviously all nodes are running the same executable.
In addition to the many "Failed to decrypt and verify packet", I had
many dropped packets.

Downgrading to 1.1pre9 fixed the issue.
