SP_error: (-11) Illegal session was supplied
hi,

im trying to get spread and wackamole running to build a simple
cluster of vpnservers. the cluster should consist of two nodes
which are both online and get one out of two vips assigned.
one of the vips are told to the clients resolving vpn.dom.com.
i use simple dns roundrobin.
when one of the machines gets a problem the othermachine detects it -
shoots the machine in the head and gets the other vip assigned.

i just cant get wackamole running.

here is the output when running "wackamole -d -c /etc/wackamole.conf"

connecting to 4803
Clean_up called
Dequeued arp spoof notifier.
No such interface
Dequeued arp spoof notifier.

Spread connect failed [-9].

...and-so-on



i played around with wackamole.conf,spread.conf and spread.access_ip
but nothing seems to change the behavior :(

i included those configs below. anyone got a clue what i have done wrong =
?
for completeness: i use linux-2.4.21, on debian woody, wackamole-2.0.0
and spread-3.17.1.


thanx in advance

ok, fixed it, it had something to do with authentification.
now i set it to NULL (spread.conf) and everything works fine.
only thing i see is when i add the -d flag to wackamole on
startup it segfaults.

thanx

Can you provide a full back trace of the segfault? Compile wackamole
with -g (might be default). Run (as root):

gdb ./wackamole
r -d

then when it segfaults type: "bt full" and mail back the output.

BTW, your prefer line looks suspect. You should remove it completely.
Wackamole isn't managing your "real" ip addresses, so it doesn't care
about them. And you preferred an entire subnet... I think you
configuration will accomplish what you want without a Prefer directive
at all.

Thanks!
