Synchronization
 
Hi,

First of all, I'm completely new to Linux and really need your help!

I have a dedicated server that I rent with a french company (OVH) with Redhat 7.2 that I access through the webmin interface. A website is hosted on this server. Clients will upload images on this server. What I need to do is to synchronise the folder that will contain the images with a folder on my server here in Mauritius in real time, i.e. when a client upload an image it will directly come to my folder here on my server.

Does anyone has a clue on how I will do this?

With many Thanks,

Laurent Fayolle

You could use a combination of inotify and ftp on the French server to send the new file to your Mauritius server or you could NFS soft mount the relevant subdirectory on the French server onto your Mauritius server.

Thanks for your quick answer fpmurphy.

I downloaded inotify_tools from sourceforge, and tried to install it using a tutorial on how to install an app, and it does not work, here is the output:

Could you help me with this?

I really don't know how I will use this with an ftp to make it work... As already said before, this is the very first time I work on a linux environment...
