vnc problem: unable to connect to vnc server

[Giulio Morgan <mickle@panix.com>]

I am trying, unsuccessfully, to make a VNC connection from Windows98 (office of
my client) to my woody machine. Perhaps I am misunderstanding something about
the usage of VNC, and if anyone could help, I would really appreciate it.

I start the vncserver by
        $ vncserver :4,
then check for my password in ~/.vnc/passwd. I discover it to be
        \111A\222\333P\444L\555,

I then launch vncviewer from the windows machine, and am prompted for the
address I wish to establish a connection to, I type in "my dynamic ip
address:4", and I am then prompted for "session password", and type
        \111A\222\333P\444L\555,
and I get a notification: VNC authentication failed!

Following is the vnc log for this session, and I am unable to decipher what I
am doing incorrectly, and, as mentioned, need help

Any thoughts will be much appreciated. Also, one trivial question, what is the
easiest way for me to determine my ip address. Currently, I check the ppp log
which identifies the address of the local and remote machines when a connetion
is established. This involves "su"ing, opening and scanning the log, looking
for a smarter way. Sorry for the dumb question.

Thanks very much,
