Get the public key for a domain

Updated July 7, 2017


This article discusses a Serv-U limitation and workaround in retrieving the public key for a domain.


  • All Serv-U MFT versions
  • Linux OS


In common SFTP communication, the server sends a public key fingerprint to the client software. This fingerprint is cached for future connections.


Currently, Serv-U has no capability to send or retrieve the public key. As a workaround, you can use the ssh-keyscan command. Refer to examples in Can I automatically add a new host to known hosts? (© 2017 StackExchange Inc., available at, obtained on July 6, 2017.)
