question: restrict access to a machine on user-basis
hello everybody, does anyone have an idea how to restrict access to a machine on user-basis? For what I have in mind, it would be desireable, that some users can access the machine only via ftp, but not via ssh, etc. thanks rüdiger

How many different types of users do you have? If you have a group of unix users (which need ssh etc) and a group of users using linux only as a file server, you might try to authenticate against a different database. E.g. ldap or a samba-pdc for the fileservices, but not for "true" unix users, which would need a shadow entry. This is just a simple suggestion, not the general answer to your question. CU, Lars.

PAM has the answer to all your questions :-)
This is exactly what /lib/security/pam_group.so (PAM group authentication module) was designed for...

thanks rüdiger
Use /bin/false for users who do not need shell access. Praise
