user based ftp and sendmail restriction
 

Hi all,

Do anyone know how we can disable the sendmail and ftp client from linux box based on user account? For example. i want to disable user A only not able to use the entire services from all my linux box.

Thanks..

I've never tried it but I think you can do it with /etc/hosts.allow and /etc/hosts.deny. For example:

/etc/hosts.allow:

ALL: ALL

/etc/hosts.deny:

smtp: user@example.com
vsftp: user@example.com

This will enable all users and disable user@example.com from access. Try it.
