PureFTPd Manager is a production-quality and standard-conformant FTP server.
Edit by : PureFTPd Manager is a simple Cocoa frontend to PureFTPd, a free (BSD), secure, production-quality and standard-conformant FTP server based upon Troll-FTPd, for Mac OS X.
ust a quick update to let you know that PureFTPd Manager 1.7 is out. It runs on Mac OS 10.2+ and has successfully been tested with Mac OS 10.5 (fresh install and update scenarii).

Id also like to thank you all for your Patience and all your kind emails.
Cheers to you all and Merry Christmas !
Its a Minimal server (112KB) with directory aliases, virtual users, FTP/TLS capabilities and Bonjour support.
It can transfer at 1.2MB/s (scp/sftp max speed is around 350KB/s).
A Default certificate for FTP/TLS is installed to /etc/pureftpd.pem. You can use this one or replace it by your own self-signed certificate.

The package is accessible through the Installer.app, under the Network category.
People who feel clever enough to install it manually can download the archive here.

Im also working on PureFTPd Manager to make it compatible with Mac OS 10.5. More news on that later. you can free download PureFTPd Manager 1.7 now.
