Re: [suse-security] NFS over VPN
I appreciate all the feedback, it really made me reconsider a few things. But what about real-time updates though? As far as i know, rsync could be used from cron or something similar, in other words in timed bursts, so if one machine dies the other one (backup) is not guaranteed to have up-to-date information. That is why i was thinking nfs... On Thu, 21 Sep 2000, Volker Kuhlmann wrote:
recently at the place where i work a collegue came up with an idea to use nfs over vpn to sync our webservers. i have not done much work with either, and i have two questions about it. first, is this a practical solution? and second, im a bit stumped about resources on the subject (i do have nfs documentation, but not much of vpn resources, and nothing on how to combine the two).
Arrrg - you want rsync. What you suggest is an absolute waste of time! rsync is one of the most useful tools around. You can as easily have it use ssh instead of rsh. Problem solved. No need to set up VPNs.

In what way you would use NFS? You have a third server, a NFS server, ain't? But what do you do if that server crashes? Then both your WWW-Server are unable to work... Usually you need somewhere to "disks" (maybe on different servers) that keep those data. If so, you need to sync or copy between those disks anyways. So you would nfs-mount the other disk and make a local sync or copy. Here you would use rsync to improve speed (or a similar tool which is optimized for such purposes). If you use rsync, you don't need NFS, since rsync is able to work via networks. You won't get in trouble with security, since rsync is able to use SSH. To put it in one sentence:
Arrrg - you want rsync.
