FTP Service in Orenosv

• Runs inside main HTTP server.
• FTP status can be viewed via HTTP server.
• User accounts can be added and modified while the service is running.
• User password file can be shared between HTTP and FTP services.
• User passwords can be either clear-text, MD5-hashed or encrypted.
• Allows ordinary users to change their password on HTTP service.(CGI)
• OS authentication of users and OS ACL checking are also supported.
• Resumable file transfers (UP & DOWN).
• Network bandwidth throttling per URL groups.
• EPRT/EPSV support for NAT and IPv6 environments.
• Support per-socket TCP keepalive to keep control connections up during long transfer.
• Supports -R option in NLST (recursive directory listing) for performance.
• Virtual directories (directory aliases) like HTTP server.
• User-specific virtual root directories.
• Large file (>2GB) support.
• Concurrent login limit per account or per host.
• Servers and clients that are both behind NATs can exchange files. (detects router's dynamic IP address).
• Supports FTPS (FTP over SSL) for secure FTP environment.
• Allows clients to set last modified time of files on server. (MFMT). Also supports extended MDTM format for the same purpose.
• UTF-8 support(RFC2640 + OPTS UTF-8 + "utf8 on"(explorer extension))�B
  However, because UTF-8 filenames are converted to OEM codepage of the host, filenames are restricted to those of the OEM codepage.
  UTF-8 functionality verified with Windows Explorer and Smartftp v1.0.970.
• Supports One Time Password (S/Key), which avoids sending user password in the clear over the network.

• Current implementation won't scale to hundreds of concurrent clients.
