I cannot say it better than already mentioned on my own blog [1]. Being so critical for the management of DeforaOS, this project also has a page here [2], and can therefore be downloaded from multiple places:

• HTTPS: https://www.defora.org/os/project/download/12/DaPortal
• HTTP: http://ftp.defora.org/pub/projects/daportal/
• FTP: ftp://ftp.defora.org/pub/projects/daportal/
