For security reasons, you should install ProFTPD using an unprivileged user and group. As the root user:
groupadd -g 46 proftpd && useradd -c proftpd -d /srv/ftp -g proftpd \ -s /usr/bin/proftpdshell -u 46 proftpd && install -v -d -m775 -o proftpd -g proftpd /srv/ftp && ln -v -s /bin/false /usr/bin/proftpdshell && echo /usr/bin/proftpdshell >> /etc/shells
Install ProFTPD as an unprivileged user by running the following commands:
./configure --prefix=/usr --sysconfdir=/etc \ --localstatedir=/var/run && make
Now, as the root user:
install -v -d -m775 -o proftpd -g proftpd /srv/ftp: Create the home directory for ProFTPD.
ln -v -s /bin/false /usr/bin/proftpdshell: Set the default shell as a link to an invalid shell.
echo /usr/bin/proftpdshell >> /etc/shells: Fake a valid shell for compatibility purposes.
The above two commands can be omitted if the following directive is placed in the configuration file:
By default, proftpd will require that users logging in have valid shells. The RequireValidShell directive turns off this requirement. This is only recommended if you are setting up your FTP server exclusively for anonymous downloads.
--sysconfdir=/etc: This prevents the configuration files from going to /usr/etc.
--localstatedir=/var/run: This uses /var/run instead of /usr/var for lock files.
This is a simple, download-only sample configuration. See the ProFTPD documentation in /usr/share/doc/proftpd and consult the website at http://www.proftpd.org/ for example configurations.
