[Openswan Users] Distro upgrade broken ppp connection?

[Mark Williams]

Hi all,

Over the weekend (possibly foolishly) i did a 'apt-get dist-upgrade"
to squeeze as lenny didnt have some newer packages i needed.

Now im having some VPN connection issues :(
Ive gone over my old confs, and fixed up all the new ipsec, xl2tpd and
ppp confs/errors where ive found them.

ipsec/xl2tpd connects ok (from what i can tell), but pppd seems to
drop the connection immediately.

My VPN up script looks like (worked in the past):
ipsec auto --up cf-tunnel
sleep 10s
echo "c cf-tunnel" > /var/run/xl2tpd/l2tp-control

On running, i get:

104 "cf-tunnel" #1: STATE_MAIN_I1: initiate
003 "cf-tunnel" #1: ignoring unknown Vendor ID payload

/var/log/messages shows:
Nov  1 15:05:37 linux pppd[1718]: pppd 2.4.5 started by root, uid 0
Nov  1 15:05:37 linux pppd[1718]: Using interface ppp0

Ive done some googling on the "Terminating on signal 15" problem,
butwithout much help.

Any ideas on where i can look for more info on why pppd is failing?

Thanks in advance!
