Getting Error while pushing .csv file to SFTP location

[hameetkaur]

Hi,

I have came across a requirement where I need to post a .csv file to my mid server and push to an SFTP location.

My SFTP location uses a username + password authentication method .

For that I am using the export set, and try to call a MID Server Script Include through a JavaScript probe, but that does not seem to be working. Could any one please help?

var SFTP = Class.create();
SFTP.prototype = {
    initialize: function() {
        this.File = Packages.java.io.File;
        this.J2ssh = Packages.com.sshtools.j2ssh;
        this.targetHost = probe.getParameter('host'); //hostname or IP address of the SFTP server
        this.targetPort = probe.getParameter('port');
        this.targetUser = probe.getParameter('user');
        this.targetPassword = probe.getParameter('password');
        this.targetFile = probe.getParameter('target') + probe.getParameter('filename');
        this.sourceFile = probe.getParameter('source') + probe.getParameter('filename');
        this.deleteFile = probe.getParameter('deletefile');
    },
    fileTransfer: function() {
        try {
            this._sftp();
            if (this.deleteFile) {
                this._deleteFile();
            }
        } catch (ex) {
            ms.log('SFTP Error: ' + ex);
        }
    },
    _authenticate: function(ssh) {
        var passwordAuth = new this.J2ssh.authentication.PasswordAuthenticationClient();
        passwordAuth.setUsername(this.targetUser);
        passwordAuth.setPassword(this.targetPass);
        var result = ssh.authenticate(passwordAuth);
        if (result != new this.J2ssh.authentication.AuthenticationProtocolState().COMPLETE) {
            throw 'SFTP Authenticate Failed: ' + this.targetUser + '@' + this.targetHost + ':' + this.targetPort;
        }
    },
    _deleteFile: function() {
        try {
            new this.File(this.sourceFile)['delete']();
        } catch (ex) {
            throw 'SFTP Delete: ' + ex;
        }
    },
    _sftp: function() {
        ms.log('SFTP Connect: ' + this.targetUser + '@' + this.targetHost + ':' + this.targetPort);
        var ssh = new this.J2ssh.SshClient();
        try {
            ssh.connect(this.targetHost, this.targetPort, new this.J2ssh.transport.IgnoreHostKeyVerification());
            this._authenticate(ssh);
            this._transfer(ssh);
        } catch (ex) {
            throw 'SFTP Error: ' + ex;
        } finally {
            ssh.disconnect();
        }
    },
    _transfer: function(ssh) {
        try {
            sftp = ssh.openSftpClient();
            sftp.put(this.sourceFile, this.targetFile);
            ms.log('SFTP Transfer: ' + this.sourceFile + ' copied to ' + this.targetHost + ':' + this.targetPort);
        } catch (ex) {
            throw 'SFTP Transfer: ' + ex;
        } finally {
            sftp.quit();
        }
    }
};

While running this I got below error message :
The Transport Protocol thread failed
java.io.IOException: The socket is EOF at com.sshtools.j2ssh.transport.TransportProtocolInputStream.readBufferedData(TransportProtocolInputStream.java:187)

while running the below command  on MID server, I got below error:

ssh -vvv <user>@<host>

debug1: kex: algorithm: curve25519-sha256

debug1: kex: host key algorithm: rsa-sha2-512

Please note that  I am using 'j2ssh' (Java Library)  in my MID Server Script Include.
