Re: [pgsql-www] FW: (AUSCERT ESB-2003.0563) CERT Advisory CA-2003-21

I have been running ProFTPD (www.proftpd.net) on all my servers for over 5
years now, including ftp3.ca. ProFTPD has apache like configuration as well
as modular expandability, can be configured to run as a stand alone daemon,
or through inetd and runs as an unprivlidged user.
