I had forgotten to update my password in /etc/ppp/options.  I'm calling a
server running NT.  Now the log looks like this:

LEGEND
12.34.56.1, eth1 = my humble client cable modem
192.168.1.* = the remote network I'm trying to connect to

(Actually this is the second time I've done it this boot-up.  The first
time it used ppp0, and though I did "ifconfig ppp0 down", it didn't
recycle the interface this time)
