pasUnity 4.69.0.0 RTM is now generally available.

This release of pasUnity brings a major update to the File Transfer Agent, adding implicit FTPS, an SFTP server, and new controls over which protocols each agent accepts.

SFTP

The File Transfer Agent can now run an SFTP server on its own port.  SFTP users sign in with their portal credentials and see the same matrix folders they see over FTP, and uploads are stored as data files exactly as FTP uploads are.  Each agent has its own Ed25519 and RSA host keys, and an agent can copy its host keys from another agent so that agents sharing one address present the same key to clients.  The SSH server uses modern key exchange (including curve25519 with strict key exchange) and AES encryption, allows file transfer only (no shells, commands or port forwarding), and slows down repeated failed sign-ins from the same address.

FTPS

The File Transfer Agent can now run implicit FTPS (TLS from the first byte, traditionally port 990) alongside FTP.  Each agent can now choose whether its FTP port accepts plain FTP, explicit FTPS (AUTH TLS), or both, so you can require encryption before anyone signs in.  Passive data connections can be limited to a configured port range to simplify firewall rules.

FTP Improvements

The FTP server has been reworked for compatibility with a wider range of clients, including WinSCP and curl.  Directory listings and file times now follow the FTP standards, TLS connections now close cleanly so completed transfers are no longer reported as failed, and each connection now runs independently so idle clients no longer slow down other users.  Changing the FTP port or turning FTP off now takes effect immediately.

Agent Editor

The Agent Editor groups the file transfer settings together, enables each setting only when it applies, and shows a tooltip for every option.  The help has been updated to cover SFTP, implicit FTPS, the protocol options and the passive port range.
