From: Kousik Maiti on 21 Jan 2010 07:00 You need cross connected cable to connect 2 pc via lan card . http://en.wikipedia.org/wiki/Ethernet_crossover_cable After connecting 2 pc via that cable you just put ip address of same class .. Then you can communicate between 2 pcs On Thu, Jan 21, 2010 at 5:15 PM, Rodolfo Medina <rodolfo.medina(a)gmail.com>wrote: > Rodolfo Medina wrote: > > >>> I just bought the Acer One netbook, on which Lenny seems to work fine.. > >>> What I need now is: > >>> > >>> 1) connect it to my old Hyundai laptop so to share data between the > two; > >>> > >>> 2) periodically save, e.g. to the Hyundai the changes I made in my home > >>> directory in the Acer and viceversa.

Maybe > some special option of rsync? How are you calling rsync? That's exactly what it doesn't. It only transfers files that have changed, and only the parts that have changed. Naturally, it needs to look at each file to see if they are equal or not, it cannot guess which files are changed. By default this is based on the modification time (and possibly size, I'm not sure), which is rather fast. -- "Hey! Who took the cork off my lunch??!" -- W. C.

That saves some configuration hassle. Else just buy a crosslink cable and set the networks on both computers appropriately. > I'd keep it simple : ssh + rsync. Run: rsync -auvz --delete ssh://remotepc/dir/on/other/pc /dir/on/this/pc to get the new stuff from the other pc to the one you're currently working on. To update, just reverse: rsync -auvz --delete /dir/on/this/pc ssh://remotepc/dir/on/other/pc -auvz does: -a => archive: saves permissions, users etc, -u => update: only newer files are transmitted. without this option older changes will be transmitted too, which might result in a loss of current changes -v => verbose: can also use -P, giving a progress indicator -z => compress: faster over (slow) networks Sjoerd PS.
