Is possibile to use proxy with sftp connection ?

let Client = require('ssh2-sftp-client'); let sftp = new Client(); sftp.connect({ host: '127.0.0.1', port: '8080', username: 'username', password: '******' }).then(() => { return sftp.list('/pathname'); }).then((data) => { console.log(data, 'the data info'); }).catch((err) => { console.log(err, 'catch error'); });

I use this type of code but is there an option for setting proxy ?

I struggled a bit for having this module work behind a corporate proxy, trying with ssh2, socksv5 and some of its forks.

I finally got it working using the (very simple to use) socks module.

Here is my solution:

import { SocksClient } from 'socks';
import SFTPClient from 'ssh2-sftp-client';

const host = 'my-sftp-server.net';
const port = 22; // default SSH/SFTP port on remote server

// connect to SOCKS 5 proxy
const { socket } = await SocksClient.createConnection({
  proxy: {
    host: 'my.proxy', // proxy hostname
    port: 1080, // proxy port
    type: 5, // for SOCKS v5
  },
  command: 'connect',
  destination: { host, port } // the remote SFTP server
});

const client = new SFTPClient();
await client.connect({
  host,
  sock: socket, // pass the socket to proxy here (see ssh2 doc)
  username: '.....',
  privateKey: '.....'
});

// client is connected

My bad, got this working using @jmorino solution, just dunno why but i need to pass the socket property in the object… my code is as follow:

const {socket} = await SocksClient.createConnection(options)
                console.log('SCOCKET CONNECTED. Connecting to SFTP...')
                const sftp_client = new SFTPClient();
                await sftp_client.connect({
                    host: '****',
                    sock: socket.socket,
                    port: 22, // Normal is 22 port
                    username: '***',
                    password: '***',
                    algorithms: {
                        serverHostKey: ['ssh-rsa', 'ssh-dss'],
                    },
                }).then(async () => {

                    console.log('SFTP CONNECTED!')
    

                }).catch((err) => {
                    console.log('error ' + err)
 
                });
