I have not done this before, but it looks do able. Are your user going to be using ssh, or is this just a SMB box? If it is just a SMB box, then I would just set the shell account to "nologin" since that is separate from the SMB account. Also I guess you could set a up firewall and restrict the ports that can talk on the LAN. -Erik- _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
