I install the machine with the "KDE Workstation" options. When I log in as a normal user, I try to FTP to the local host. It connects, then hangs for a moment (without offereing a chance for me to log in). Then, it gives a message: service not available, and quits. FTP works to other sites for me. FTP appears to be a started service by looking at the inetd.conf file (it's not commented out).
I am experiencing the same problem with the same symptoms. I also have this problem with Telnet. These utilities worked fine a few days ago and since then, I have installed a different monitor and have worked on getting a PPP connection up and running.
What does the log file "/etc/messages" say? Also try "telnet 127.0.0.1 21" and take a note about what it says...
Workstation installs don't install an ftp server by default, so the behavior is correct. rpm -i /mnt/cdrom/RedHat/RPMS/wu-ftpd-2.6.0-1.i386.rpm should fix this. If you want to permit anonymous access, install the anonftp RPM as well. If you have installed wu-ftpd and anonftp, feel free to reopen this bug.
