Compare files across 2 UNIX boxes

Compare files across 2 UNIX boxes
Is it possible to compare two files which reside on different UNIX boxes?
(I'm using HP POSIX/Korn)
Consider the scenario of a pre-production environment (box 1) and a production environment (box 2) I would like to check if some files on both boxes match or not.
It's quite straightforward on one box:
#----------------------------------------------------
# Function to compares files and display differences
#
# $1 = file1, $2 = file2
#
# cmp with option -s gives the following return codes:
# 0 - identical
# 1 - different
# 2 - inaccessable/other
#----------------------------------------------------
function fn030_compare_file {
cmp -s $1 $2
if [[ $? -gt 0 ]]
then
echo "*** Difference in files! -----> $1 <---> $2"
else
echo "*** OK, Files identical -----> $1 <---> $2"
fi
return
}
The only alternative I can think of is to copy the files to one box, then compare from there.
NOTE: I found an excellent shell script which recursively compares the contents of two directories on one box (to find this do a google search on "cmptree"...)

GENBOX(1) General Commands Manual GENBOX(1) NAME
genrbox - generate a RADIANCE description of a box SYNOPSIS
genrbox mat name xsiz ysiz zsiz [ -i ][ -r rad | -b bev ] DESCRIPTION
Genbox produces a RADIANCE scene description of a parallelepiped with one corner at the origin and the opposite corner at (xsiz, ysiz, zsiz). The sides of the box will be parallel to the three coordinate planes. The surfaces that make up the box will be modified by mat and their identifiers will begin with name. The -i option can be used to produce a box with inward directed surface normals. The -r option can be used to specify the radius for rounded edges. The -b option can be used to specify the indentation for beveled edges. EXAMPLE
To produce a rectangular box made of wood with beveled edges: genrbox wood box1 5 8 3 -b .5 > box1 AUTHOR
Greg Ward BUGS
Because spheres and cylinders are used to construct boxes with rounded edges, a transparent box of this type appears quite messy. SEE ALSO
