| I went to FTP some file from another machine and ran into a problem I
had before with redhat 9.
It had something to do with two modes of FTP traffic and an entry that
had to be made manually in a configuration file.
Anyway, what happens is that I ftp to a host and login. When I ls I get
a connection refused message.

For FTP, you must open two ports, 20 and 21. Refer to your firewall's
documentation, which you do not identify, on your distribution, which you
do not identify.

Sorry, It is Fedora2 using (I believe) iptables. I did man iptables
and it doesn't tell me where the files are stored, at least in
language I can understand.

Why not use the GUI configuration tool instead of trying to sort it out
yourself? I ask this because you may not be quite ready to
hand-edit /etc/sysconfig/iptables and restart the service.
The configuration tool on FC2 is named "system-config-securitylevel". It is
listed as "security level" in the system settings menu under KDE. You can
run it from a shell:
$ system-config-securitylevel

Because it doesn't work. I have FTP checked and I still get connection
refused messages when I try to ls a remote computer.

It looks like I'm going to have to.

I'm running Gnome and found it but it doesn't work.

Maybe the connection was refused *there*. Did you check the remote firewall?
With that error message, the problem is more likely to be on the server,
not the client.

Yes, I tried different servers with the same results and I booted into
OS/2 and tried and had no problems.
Like I said, I had this problem last time I tried linux (redhad 9) and had
to manually edit iptables. The problem is that the documentation, like
all linux docs, is terribly written.
