[Jool-list] How to debug joold?

[Nico Schottelius]

Hello again,

I am giving joold a second try (thanks for the log change!), now using
the multicast address ff05:db8:64::64 ("site local" according to
wikipedia).

Checking the session table on one of the two routers it looks good, but
the other router does not have the same entry. Sniffing traffic using

tcpdump -ni any port 6464

also does not show any outgoing or incoming traffic on that port.

Looking for

tcpdump -ni any icmp6

before starting joold also does not show any traffic. Shouldn't joold
send MLDv2 messages?

When I attach myself to joold using strace -fF, it stays in recvmsg and
does not do anything when a session is created.

Or asked differently: how do you usually debug joold communication? I
did not see any verbose: true or debug: true flags.

And I've seen the different instance names - should joold propagate all
session accross all instances by default or only selected ones?

Sorry for the newbie questions - jool(d) looks quite nice, but I'm not
yet fully used to how it is designed.

Best,

Nico
