Yes, I read the documentation for Kerberos and it seems to be too complicated. I think that it is an overkill to connect to computers. In my case the LAN is the whole University and it is very easy to spoof an IP, I checked that. So NFSv3 might not be such a good idea. How about NFSv3 over a ssh tunnel? That should be easy to implement. I compared the transfer of a file of 700Mb between scp (encrypted) and samba not encrypted, and the result is: -scp: 38 seconds, and 25% of overhead in one of the 4 cores of the computer -samba: 18 seconds and no overhead So in my case I think it can be acceptable to do a ssh tunnel as most of the times most of the cores of the computer are not used and there is not a big traffic of data. Are there other disadvantages of using a ssh tunnel? Thanks, Dan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
