Thanks. I have fixed this now -- details at http://stackoverflow.com/questions/33690689/no-matching-host-key-type-found-apache-mina-sftp-server
> You ought to update to version 1.0 before moving on. At the time, I couldn’t find a 1.0 version of "sshd-sftp" I didn't realise that it is included in "sshd-core" v 1.0. That wasn't the main fix though; I had to add in BouncyCastle and pass the right magic string to "hostKeyProvider.setAlgorithm". -----Original Message----- From: Stefan Magnus Landrø [mailto:stefan.lan...@gmail.com] Sent: 13 November 2015 13:41 To: users@mina.apache.org Subject: Re: Apache MINA SFTP server - "no matching host key type found" You ought to update to version 1.0 before moving on.
