problem with vnc viewer not drawing a window

["Michael Litchard" <michael%schmong.org@localhost>]

vncviewer starts, but gives this error message
main:        InStream max string length exceeded

It will not draw a window

Here's the log from the machine running vncserver

xrdb: Can't open display ':1'

xterm Xt error: Can't open display: :1
twm:  unable to open display ":1"

I tried setting the DISPLAY variable to this
192.168.1.112:1
and here are the contents of /sys/.vnc/xstartup
#!/bin/sh

xrdb $HOME/.Xresources
xsetroot -solid grey
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
twm &


Could someone help me troubleshoot this? Thanks.


What is slightly irritating is I had vnc working on another (now dead)
computer, and I can't find the tutorial from which I got my original
xstartup file.
