Hi Team, I am using the "tap-sftp" from singer https://github.com/singer-io/tap-sftp Getting one issue saying

paramiko.ssh_exception.SSHException: Incompatible ssh peer (no acceptable host key)

For this I made a change in the client.py

self.transport._preferred_keys = ('ssh-rsa', 'ecdsa-sha2-nistp256', 'ecdsa-sha2-nistp384', 'ecdsa-sha2-nistp521', 'ssh-ed25519', 'ssh-dss')

def __try_connect(self):
        if not self.__active_connection:
            try:
                self.transport = paramiko.Transport((self.host, self.port))
                self.transport.use_compression(True)
                self.transport._preferred_keys = ('ssh-rsa', 'ecdsa-sha2-nistp256', 'ecdsa-sha2-nistp384', 'ecdsa-sha2-nistp521', 'ssh-ed25519', 'ssh-dss')
                self.transport.connect(username = self.username, pkey = self.key)
                self.sftp = paramiko.SFTPClient.from_transport(self.transport)
            except (AuthenticationException, SSHException) as ex:
                self.transport.close()
                self.transport = paramiko.Transport((self.host, self.port))
                self.transport.use_compression(True)
                self.transport._preferred_keys = ('ssh-rsa', 'ecdsa-sha2-nistp256', 'ecdsa-sha2-nistp384', 'ecdsa-sha2-nistp521', 'ssh-ed25519', 'ssh-dss')
                self.transport.connect(username= self.username, pkey = None)
                self.sftp = paramiko.SFTPClient.from_transport(self.transport)
            self.__active_connection = True
            # get 'socket' to set the timeout
            socket = self.sftp.get_channel()
            # set request timeout
            socket.settimeout(self.request_timeout)

Even after making this change, its not resolving the issue.

What type of key are you using? What version of

paramiko

is the tap using?

I was using "2.6.0" but after upgrading the issue is resolved. Thanks

Nice!
