Hello, could someone tell me an alternative to NFS, which is safer? I search for an implementation authenticated not only over uid and gid. I think about DCE DFS, but there is'nt an implementation for linux yet. Have someone a hint or some experience in this case? Bye, Michael

What about ssh with scp to copy files. If you create keys and enter them in the ~/.ssh/authorized_keys you can copy files without password prompt. You have a secure authentification and can copy the files crypted and compressed (with "scp -C").

Performance is a problem. scp is wonderful, but by encrypting or compressing it wastes a lot of time. Encryption is not really needed in some intranets. So how could we use the tool and tell it to just plainly copy files after authentification without encryption? Anybody knows? Rainer

I don't look for another scp or rcp. What I want, is a distributed file system. Thank you, Michael
Hi Michael,

system. Thank you, Michael
Have a look at rsync, it's on the suse distribution, if I'm not mistaking... Regards, Jan. -- mailto:jan@spier.be http://www.spier.be SPIER bvba, Knaptandstraat 96 - 9100 Sint-Niklaas - Belgium Tel: + 32 3765 9061 Fax: + 32 3765 9062

This is good if you have some small files but I don't want to copy large data files (> 100 MB) to hold them twice. I search for a distributed file system with an authentification routine. For small data I use scp of course. Thank you. Bye Michael

Well I fear there is no alternative which you can simply plug in. There is: NFS v4: Based on NFS, but not yet finished (no code exists) http://www.nfsv4.org Andrew File System: Offers everything you want, but I don't know how stable it is. AFS is supported for a wide range of platforms. At DASY in Zeuten I heard it took quite some time until it was working. (IBM AFS) http://www.transarc.com/Product/EFS/AFS/index.html http://oss.software.ibm.com/developerworks/opensource/afs/ http://www.openafs.org/ Coda File System: Opensource project similar to IBM's AFS. http://www.coda.cs.cmu.edu/ And for copying files I also would recommend rsync (rsync.samba.org), but this is not what you want. I therefore would recommend: Stay with your NFSv3 system. If you don't have controll over all clients, you may deside to export only the user directories of that system or make sure that only you can become root on those computers. http://nfs.sourceforge.net/nfs-howto/ (If you use NIS: Note that there are also numberous problems!) If you cannot assure that you cannot controll root on that client, you should have a look at the AFS.
