Hi, I don't know if this has been asked before, but I'll try anyway. And please ignore this if you think it's not related to the topic of this list. :) I am going to do some testing with two computer (just for fun), both with SuSE 7.0, and a firewall between them (OpenBSD 2.7). The first computer will be accessed normally by users while the other one will be a NFS server to the first one (ie. the users homes will be automounted from the NFS server). - Is it possible to filter the NFS trafic well? - Do I need similar passwd/group/shadow/gshadow files on both computers? - Is it possible to have the NFS computer as master password storage for the first one? - Can RADIUS be used to this (I know a PAM exist for RADIUS, but will it fit my needs?)? - Other alternatives? NIS? NIS+? Transfer the files by SSH on a regular basis? The main question would be: what alternatives exist if you want to share user ids and passwords between two or more computers... and in a hopefully secure way (ie. if you get root on one computer, you won't be able to get the whole password list from the master). Have a nice day! Dan Sveen Olsen
