nfs pipe and xwd

I'm trying to make a mini utility to grab and annotate screen shots. I have 2 workstations (call them "here" and "there") My home directory is physically located on there and NFS mounted on here. "xwd | display" should let me grab the contents of an x window and open it with ImageMagick's display function and it works fine in every case except when I'm logged in to here when it fails with "Segmentation fault (core dumped)" If I do "xwd > filename" and then "display filename" it works. Any suggestions?

Re: nfs pipe and xwd

Could you try something like:

on here
# xwd -display there

Check the
# xwd -help
for more options.

xwd -display there doesn't work because then xwd waits for me to pick a window there which I can't because I'm here.When I ctrl-c to quit I get the usual "seg fault-core dump"

Any other suggestions?
