[ProgSoc] Synchronising files (with encrypted transport and centralised storage)
I have an interesting problem which I have been thinking about for a
while. I would like to have the files on two or more machines
synchronized. Unfortunately there is a firewall between the two
machines, but I can use a third-party FTP server to store the
centralized version. However, I don't trust the FTP server, and would
like the data encrypted whilst it is transported and stored.
Office PC <=> FTP server----Firewall------ <=> Home
(secure) syncs to (unsecure) syncs to
Does anyone know any software that synchronises files between two
machines, using FTP (though I'm open to other ideas) and that would
either provide encryption support, or allow running another arbitrary
program to encrypt/decrypt the files that have changed?
The best idea I have so far, is to use the perl 'mirror' scripts. I was
going to use one of the options that allow you to specify a compression
program to do the encryption/decryption, although it could be tricky.
Unfortunately, I think 'mirror' is only uni-directional. I need
bi-directional. I thought about using 'rsync' but it would most likely
require another port to be opened (unless I run it with 'ssh'). It also
doesn't support running commands.
Thanks in advance!!
