local address announcements

Hi everyone,

you can find the current version of my enhanced tinc using subversion:
svn://tardyon.mon-clan.de/tinc

I allowed anonymous read access, so feel free to download the sources.
Unfortunately, my enhancements are based on a rather old git-checkout from
Guus.
The version should run under windows and Debian/Ubuntu.


Best,

Daniel

Hi,

Can you please e-mail me the local address announcements patch? Or tell me
where to get it? I have a setup in which I can test/use it.


Thanks,

Hi,

Are you sure it is anonymous? It keeps asking for passwords.

svn checkout svn://tardyon.mon-clan.de/tinc .

It asks me for username and password

Hi,

sorry, my bad. I tested with cached credentials.
It should work now.

Best,

Daniel

It spits out some errors. Also doesn't seem to work.
Debian system.
Replaced line 313 by:
	logger(LOG_ERR, "getifaddrs: Call to %s (%s) failed: %s",
"SIOCGIFFLAGS", inet_ntoa(((struct sockaddr_in *)&ifr ->
ifr_ifru.ifru_addr) -> sin_addr), strerror(errno));

Logging output is:

The system only has eth0, lo and of course the tinc device.

Ok, now it starts without any errors.

Still doesn't work though: 192.168.11.18 and 192.168.11.124 don't detect
each other (their names are clientbp and verweg):

There was a problem with verifying remote HMACs.
I forgot to adjust the packet length (to include the newly added flags).
Therefore, verifying HMACs in function try_harder always failed and packets
could not be allocated to nodes.

I fixed that issue, and tinc should be more stable now, although adjacent
nodes do not see each other 100% of the time.
Sending/receiving UDP packets sent to the public interfaces works though.

To reflect the change in the protocol, I increased the protocol version to
18, making it incompatible with previous tinc versions.

Hi Daniel,

Any news on the local address announcements code?
Am really eager to put it in production :-)
