: Hi Guys,
:
: It's been a while, but I just threw together a Redhat 7.0 FTP server and
: have a very basic question which has stumped me. Forgive me for what I am
: about to ask, but someone knows how to do this:
NT and other OS's have ACLs for this sort of thing. Linux/Unix uses groups.
RH uses a personal group system where everyone has their own group; your
superuser would have to be added to each personal group. You may need to do
some trial-and-error. Be careful about giving write access to the root
directory (i.e., don't 'chmod 700 /home/ftp').
Also, recognize that FTP is a security nightmare. Various ftpd have
histories of being exploited; you'll want to make sure you are watching for
security updates and installing them religiously. But even when it's
working correctly, there's the fact that your customers will be sending
their usernames and password in cleartext each time they access your system.
Given that you're allowing write access, be cautious about giving anonymous
access and test this setup thoroughly before you connect it to the net. If
you can afford the hassle of firewalling off access from everyone but your
customers, that would be nice.
