How to use a socks5 proxy? about sshtunnel HOT 18 CLOSED

Please update the sshtunnel package and retry.

from sshtunnel.

This is not possible. What you're trying to achieve is not connecting to the SSH gateway through a SOCKS5 proxy. There's no support for dynamic application-level port forwarding (equivalent to OpenSSH's client -D option).
What you can do instead is a tunnel for a single destination, if that fulfils your requirements.

from sshtunnel.

If what you mean is how to make an ssh connection to a server behind a socks5 proxy, you may first create a proxy (i.e. with pysocks) and pass it to sshtunnel. I removed the restriction for the proxy argument in SSHTunnelForwarder so now any socket-like object may be used (see sock parameter information for more details).

import socks

SOCKS5_PROXY_HOST = '1.2.3.4'
SOCKS5_PROXY_PORT = 1080
s = socks.socksocket()
s.set_proxy(socks.SOCKS5, SOCKS5_PROXY_HOST, SOCKS5_PROXY_PORT)

tunnel = sshtunnel.SSHTunnelForwarder(
    ('ssh_server_ip', 22),
     ssh_username='user',
     ssh_password='secret',
     remote_bind_address=('127.0.0.1', 5555),
     ssh_proxy=s,
)

from sshtunnel.

I modified according you. but It not working?
Source code:

import sshtunnel
import socks

SOCKS5_PROXY_HOST = '127.0.0.1'
SOCKS5_PROXY_PORT = 1080
s = socks.socksocket()
s.set_proxy(socks.SOCKS5, SOCKS5_PROXY_HOST, SOCKS5_PROXY_PORT)

tunnel = sshtunnel.SSHTunnelForwarder(
    ('182.69.xxx.70', 22),
     ssh_username='admin',
     ssh_password='admin',
     remote_bind_address=('127.0.0.1', 5555),
     ssh_proxy=s,
)
tunnel.start()
#
print(tunnel.local_bind_port)

Error:

I updated and tried then didn't show bug it. But It's not working( It's don't run to command line this
print(tunnel.local_bind_port) )

from sshtunnel.

Yeap, I think I know where the error is. Could you please re-update (from source, not pypi) and retry?

from sshtunnel.

Still error:

from sshtunnel.

That seems more like a local issue. It's working as expected with a socks proxy set up with openssh.

[...] the target machine actively refused it

from sshtunnel.

I don't understand why it not working. the target machine actively refused it
I want to download a mp3 file with socks5 and It must be download fast. Please help me and share for me a example code to do it.
Thanks

from sshtunnel.

@thehung12a3 the example already provided should be valid. At first that could not work because before 0.0.8.3 the proxy had to be a paramiko.Proxycommand instance. Now this restriction is gone and any socket-like object may be used as proxy.
You may first try if you can access via your proxy with openssh:

$ ssh -o ProxyCommand='nc -x YOUR_PROXY_IP:YOUR_PROXY_PORT %h %p' \
 SSH_SERVER_TARGET -L <...>

from sshtunnel.

I can not access via socks5 in firefox browser. When you release version0.0.8.3?. I'm waiting it and hope all is well.

Can you describe or make a draw of what you have at the moment? I'm not sure I'm understanding your problem properly. With the changes I already did I was able to achieve the following:

                         +---------+
                    1080 |         |
                         | socks5  |   22+----------+  443-----------+
        +----------------> proxy   +----->  SSH     +---->    Web    |
       <-----------------+         <-----+  server  <----+    server |
                         |         |     |          | ^  |           |
                         |         |     +----------+ |  +-----------+
                         |         |                  |
                         +---------+                  +
                                                    tunnel

The scenario in this diagram worked for me with the code pasted before.

from sshtunnel.

I run the above code snippets then It's still the occur attunnel.start()

File "C:\python-64bit\python-2.7.10.amd64\lib\site-packages\socks.py", line 687, in connect
    raise ProxyConnectionError(msg, error)
socks.ProxyConnectionError: Error connecting to SOCKS5 proxy 127.0.0.1:1080: [Errno 10061] No connection could be made because the target machine actively refused it

I used pip to uninstall sshtunnel and install from new source. But not working?. I don't know how to fix it?

My scenario:
I will run the above code snippets to a connection with socks5. After that I open a firefox browser and access with socks5 to download a file mp3

from sshtunnel.

I still don't understand what's the role of the SSH tunnel here. Where is your proxy? (behind/in front of the SSH server), where's your web service (tunnelled/not tunnelled over the SSH tunnel)?
A picture is worth a thousand words BTW.

I wanted it to be like this. https://www.youtube.com/watch?v=COg_LB4Fe5o

hi
please help create socks5 with ssh auto login

from sshtunnel.

@fernandezcuesta I came here when looking for an ssh -D equivalent aka SOCKS over SSH tunnel in python. Above, in 2016, you stated that this is not supported. However, you did not state any reason or rationale why it isn't or might not be added in the future.

Can you please explain a bit why this is not supported yet, how this might be implemented and if you would like to see contributions towards it?

from sshtunnel.

Hi there. The idea was to keep it as simple as possible and not expend much time supporting what you can achieve with other packages (e.g. asyncssh).
Anyway feel free to contribute, it'll be more than welcome.
