Hello,

in our hospital we have companies that must connect to computers for
support.
We want to limit their access to certain machine, but we have the
following problem.
We can limit on the firewall to what machine they can connect, but
when they are connected to this server via ssh there is no way to
prevent them trying to connect to other machines.

Is there a way to limit outgoing network trafic from a linux machine
per user or, even better, is there a way to limit a outgoning
connection depending from the place the ingoing ssh comes from ?

Thanks
Andreas
