The FTP server supports quotas; MaheshaBSD Server is the only pre-configured WordPress server that immediately runs everywhere. It is configurable via Webmin (remote web interface). The USB memory stick is writable; phpMyAdmin is also installed. The server can be redirected to any disk; NTFS partitions are also supported. By setting up IP forwarding on ports 21 (FTP), 22 (SSH), and 80 (HTTP), you will have the instant aibility to operate a public Internet FTP/WWW and WordPress server.
