I use proftpd, which works OK with the standard debian config (included 
below). Most likely the problem is with file permissions. What you need to 
know is which username the ftp daemon uses for anonymous connections - 'ftp' 
in the standard debian setup. Then make sure the files you want to access 
anonymously are readable by this user. E.g. as root, go into the relevant 
directory and do 'chown ftp *'. Or to do this for all subdirectories, do 
'find /var/ftp/pub -print0 | xargs -0 chown ftp'. Alternatively, leave the 
ownership as it is, but make the files world-readable using 'chmod o+r *'

$ cat /etc/proftpd.conf
# This is a basic ProFTPD configuration file (rename it to
# 'proftpd.conf' for actual use.  It establishes a single server
# and a single anonymous login.  It assumes that you have a user/group
# "nobody/nogroup" and "ftp" for normal operation and anon.
