account permissions.

[Geoff Shang]

Hi:

I assume you mean outgoing FTP and telnet.  These are just executable
programs, with permissions that can be set like any other.  for example, I
have a telnet that is owned by root with group root and it has the
permissions rwxr-xr-x.  Now, I could change the group to telnet and make it
rwxr-x---.   Then only the users I put in the telnet group would be able to
access it.

there are options to the adduser command to fascilitate putting people in
existing groups, or moving people accross to existing groups.
Alternatively, you can add them by hand to the appropriate group in the
/etc/group file.

Geoff.
