OK, I tried that; however, setkey seems to return two messages as soon
as it's started, and then nothing while vpnc runs. For reference,
here is the output:
nbudin[at]kenichi-2:[~/vpnc-nortel-414]: sudo setkey -xH
14:03:58.906489
00000000: 02 0b 00 00 06 00 00 00 00 00 00 00 00 00 00 00
00000010: 02 0b 00 01 02 00 00 00 00 00 00 00 42 30 00 00
sadb_msg{ version=2 type=11 errno=0 satype=1
len=2 reserved=0 seq=0 pid=12354
14:03:58.906576
00000000: 02 0b 00 01 02 00 00 00 00 00 00 00 42 30 00 00
(These two messages came immediately when I ran the command. I then
repeatedly attempted to log into the VPN in a different terminal, but
nothing ever appeared in the setkey output.)
