RedHat 7.2 should come with an FTP server. If not you can download the rpm version from rpmfind.net and install it through command line.

The first thing you will want to do is to see if an FTP server is already installed. You can do this by doing the following from command line.

rpm -qa | grep ftp

If you don't see wu-ftpd listed, an FTP server is most likely not installed.

If wu-ftpd is not already installed you should be able to install it from the CD Rom or from the RPM from rpmfind.net. You can do it by doing the following.

mount /dev/cdrom
cd /mnt/cdrom/RedHat/RPMS/
rpm-iv wu-ftpd-2.8.1.i386.rpm (this may be different for you)
umount /dev/cdrom

Good luck!
