Re: [foxboro] Copying Displays to remote workstations


This brings one question to my mind however: if you run pdfpack on the same
newly-saved graphic on two different stations (same nodebus), does it
generate the same output file on both?  Or is it a station-specific thing?

This is the main reason for using rsync. It does not use the time stamp
of the file but actually does a checksum of the contents. It does this
in a way that is highly optimised for high latency,slow throughput
links.
Each end of the transfer does a checksum of the files and determines the
byte differences and offset into the file. Only these bytes are sent.
Eg: If you had to synchronise a large file, say 1 GB, that only had 1
byte difference, rsynch would compare the files and sent 1 byte and the
offset to update the target file.
Obviously to minimise traffic it should not be using an nfs/rfs file.
To minimise traffic rsync can rsh/ssh to the target machine and do the
update.
