Hi Mauricio, Thanks for your reply. No, I'm not using NIS or DNS to export hosts names. (or at least I didn't know how to configure => so I persume I didn't set them) > Are you using NIS to export the hosts names? Or just using DNS? [root@localhost yffung]# less /etc/auto.master # # $Id: auto.master,v 1.4 2005/01/04 14:36:54 raven Exp $ # # Sample auto.master file # This is an automounter map and it has the following format # key [ -mount-options-separated-by-comma ] location # For details of the format look at autofs(5). #/misc /etc/auto.misc --timeout=60 #/smb /etc/auto.smb /net /etc/auto.net > What does it says the file /etc/auto.master?

[root@localhost yffung]# mount /net/sf mount: can't find /net/sf in /etc/fstab or /etc/mtab > And what happens if you try to mount that dir by using the "mount" command? Thanks alot.
