Im trying to set up an ftp server on my linux box running slack 9.1, with a 2.6.8.1 kernel. When I connect from another linux box, it seems to work fine, and I can transfer files with no problem. However, from windows, I can connect, but cannot transfer any files. I continually get the message "Permission Denied" for any file with whatever local permissions in any directory. Also, I am unable to login as root, it just wont take the password, is this just some sort of thing where I cant login as root to an ftp server? Here's the text of proftpd.conf, in case that helps. Thanks.

ServerName "ProFTPD Default Installation"
ServerType standalone
#ServerType inetd
DefaultServer on

Port 21
Umask 022

MaxInstances 30
# Set the user and group that the server normally runs at.
User nouser
Group nogroup

# This next option is required for NIS or NIS+ to work properly:
#PersistentPasswd off

SystemLog /var/log/proftpd.log
TransferLog /var/log/xferlog

# Normally, we want files to be overwriteable.
<Directory /*>
AllowOverwrite on
</Directory>

# A basic anonymous FTP server configuration.
# To enable this, remove the user ftp from /etc/ftpusers.
<Anonymous ~ftp>
RequireValidShell off

# We want clients to be able to login with "anonymous" as well as "ftp"

# Limit the maximum number of anonymous logins

# We want 'welcome.msg' displayed at login, and '.message' displayed
# in each newly chdired directory.
DisplayLogin welcome.msg

# Limit WRITE everywhere in the anonymous chroot

Well, you can't login as root because you have a file called /etc/ftpusers, which is a userlist of all forbidden userids to login via FTP.

As for your Windows file xfer problem -- are you using the EXACT SAME username and password when you're logging in from your other Linux box?

Thanks for pointing out the ftpusers file. Yes, I'm using the exact same user and pass for the windows computer as for the linux one, and theres no case-sensitive issues. I did manage to get a connection and successfully transfer files with my friend's laptop (Windows XP) hooked onto my LAN. However, the transfer was slow, ~2 kb/s, and the files were corrupted when they came out on the other end. The files were just MP3s, and when I played them on his computer they were a garbled mess of noise. Still no luck from a foreign computer just over the internet though.
