I have a simple question and in spite of prescribing various linux related
mail lists i have never seen this one:
How do you bind a login/password to a certain ip?
The common way of allowing and denying access are the /etc/hosts.allow and
/etc/hosts.deny files but
assume an user 'borrows' his login/password to his buddy who also has an
account on the same linux machine.
That means, both are allowed users with authorized ip's in /etc/hosts.allow
but what if I want prevent such misusage?
Another question is if there is a way to gain root access *only* from
specific hosts, which I hopefully define somewhere in /
