Hi Marius, yeah it's weird. Manual route entries work fine, just that
ampr-ripd is silently not adding its routes. Not having any error messages
makes troubleshooting very difficult.
I'll try the main table, but here's my table 44. These routes have been
added either in my startampr script or by hand. Ignore the odd /24 within
the 44.31 /16, that was due to manual adjustments for unrelated technical
issues.
I can give the main table a try as a test (though will have issues
operationally).
ip route show table 44
default via 169.228.34.84 dev tunl0 onlink
44.31.0.0/16 via 112.213.34.1 dev eth0
44.31.48.0/24 via 112.213.34.1 dev eth0
44.31.169.0/24 via 10.43.21.3 dev ztc3q6v23i onlink
44.94.17.129 via 112.213.34.1 dev eth0 proto 44
44.136.76.0/24 dev ztuzesnqjd scope link

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 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?
Marius, YO2LOJ

Hi,
been having a few issues with IPIP tunnels of late. On my original
server (a R-Pi), which I recently resurrected, ampr-ripd suddenly
started segfaulting on startup for no obvious reason. The old system
also had a few limitations and an ageing SD card, so I decided to move
my gateway to a VPS, and updated the gateway IP in the portal
accordingly.
I ported my setup to the new server and built the latest (2.41)
ampr-ripd. I've verified that I am receiving the RIP broadcasts, and
ampr-ripd writes the encap.txt file in /var/lib/ampr-ripd. However, I
am not seeing any route updates in table 44 (the routing table I use for
ampr routing - I am using the recommended policy routing). The only
clue I get as to something not being right is a line:
SIGALRM received
I'm guessing that signal has something to do with the routing table not
being updated, but there's no other clues to help me troubleshoot.
Anyone have any ideas?
