Not clear how usernames are generated. Does every user have a fixed ID allocated to him/her? Because if the same username is used by two or more people I don't see the difference between the user account and the guest account. In any case, have a look at the postexec parameter in smb.conf. That should allow you to run a script (which can clean out the directory, e.g.) whenever a user disconnects from a share.

Re: [ilugd] [X-POST] Guest account in Ubuntu 10.04
Well I think the following can help you out. 1) for having a guest account simply create a account with any name (probably guest) that will never ask for password at login so you don't have to tell the password to everyone (if u want that account to be for public use) 2) for resetting home directories of users, you should put all your files (which u want to be there in the home directory at every login) at some different place and write a small bash/perl script to place them in user's home directory at every login after deleting whatever was there in user's home directory. Do let me know whether this was useful or useless. On Sat, Jul 24, 2010 at 9:29 PM, Kartik Singhal wrote: > We are setting up a lab in our computer center for encouraging students to > use linux.
