Just to looking for AFS or Coda file system. I never use it but i think
that will do what u want.

I am looking for a utility that will allow me to synchronize folders
between my laptop, and my server where my documents are stored.
Currently I am NFS, but please allow me to elaborate why this is not
my ideal solution.
For the first reason, my dad is a bit paranoid when it comes to
security (I am only 15, so all equipment but my laptop are technically
his). He doesn't know about what I am doing to my server 99% of the
time, but I'd like to be able to assure him that I am as secure as I
can be. Therein lies my problem: I've had to open up 5 ports on my
firewall (to only the internal network, so that's is a good thing)
just to get NFS to work.
Second, I never have gotten NFS working 100%. I can transfer files and
all that, but when I am shutting down my laptop, one of the messages I
get is an error about not being able to connect to the lockd daemon. I
tried locking down the ports (instead of the randomly chosen ones),
but I don't think I did this quite right (not sure if it's client or
server side). I've never really looked into the issue that hard,
because I don't think it's causing me any problems because I'm the
only one in the house that uses NFS (I'm the only one with a duel-boot
with WinXP and FC4).
Along with the not 100% working idea, I've also have a mysterious bug
that I've been unable to correct, and when I posted a message to this
list, I got no replys, so since I know it has to do with my NFS, I'd
like to get rid of that troubled dependency (often times causes my
laptop to lock up).
Third, I travel to school with my laptop sometimes to work on projects
there, where, if I bring my own computer I can have whatever programs
I want compared to the school where I have no permissions to do
anything. I am limited to working in Windows only or else I get some
problems when my computer tries to connect to an NFS server that
doesn't exist.
Now I'd like to go over what I'm looking for.
I'm looking for (in order of importance)...
...a synchronization scheme that integrates into the Linux file
system automatically like samba or NFS does: I can mount the
remote folder directly into my file system and the client and
server are always in sync with each other (no need to run a
synchronization program).
...a scheme that will not just rely on the server for the content:
it will keep a local copy on the client, and once the daemon can
successfully connect to the server again, will go ahead and update
the server. In short, a local caching system.
...a daemon that only requires a single, locked down port to
operate so I can lock down my firewall further.
...(maybe a bit of a stretch but) a system that can do basic
network recognition. For example: My home network consists of a
192.168.2.0/24 subnet, and additionally the wireless's name is
"ournet" (substituted actual name). If I connect to a wireless
connection that is not "ournet", it won't even try connecting. If
connect to a lan and the subnet is 172.40.0.0/16 instead of my
home subnet (192.168.2.0/24), it won't even try connecting.
I'm really hoping someone out there has an answer for me. If there is
absolutely nothing that matches my wishes, maybe there is something
out there that comes close and is willing to listen to my ideas. I'm
also a bit of a novice programmer. My brother wants me to code this
myself, but I thought it'd be much easier ask you helpful people and
see if anything already existed (I don't really want to reinvent
wheels). If the project needs some help, I'd be willing to help coding
a bit, but I am VERY new to Linux programming and tend to have
unreliable working conditions (I'm subjective to my parent's whims and
how much they will allow me to sit in front of my computer), but some
help is better than none.
Thanks for any replies I get (which I'm hoping to be many :-D ),
Justin Willmert
