Thank you David.

So this confirms that the the netlink interface has not changed and it is working.
I have no 5.13 or a similar generation system to check.

@Tony: this would tell me that your issue is probably not related to an internal ampr-ripd anomaly.

Maybe try to use the main table as a test (nu -t 44 parameter) and see if the routes appear...

BTW: what is the output of your 'ip route list table 44' command?

The command line seems ok (but you can actually drop the password parameter since the default one is used if not set via -p),
The good question is if the newer kernels changed something in their netlink behavior...

Could someone confirm if they have ampr-ripd successfully running on a 5.13 kernel?

Hi Marius, thanks for replying.  Here's the information you requested.

Kernel version:

# uname -a
Linux pridenet1 5.13.0-52-generic #59-Ubuntu SMP Wed Jun 15 20:17:13 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

Command line:

/usr/local/sbin/ampr-ripd -s -r -t 44 -i tunl0 -p pLaInTeXtpAsSwD -a 44.136.76.0/24 -L vk3jed@qf23dg

Hi Tony,

The SIGALRM is just the signal sent by the kernel as a result of a timer
set up by ampr-ripd to trigger 30 sec from receiving the last RIP
routing set and is an expected behavior.
It triggers the purging of obsolete route entries and has nothing to do
with the update of the routing tables, which happens on the fly via a
netlink socket during RIP processing on reception.

If the encap.txt is correctly saved, that means that the RIP data was
parsed successfully and sent to the kernel.

What kernel version do you use?
Can you post your ampr-ripd command line used to start up the daemon?
