problem with the tunnel ssh in whonix gateway connection refused

[y010]

hello

i installed recently the open ssh server and client

sudo apt-get install openssh-server openssh-client

but it shows me connection refused

root@host:/home/user# ssh -D 1080 10.0.2.15
ssh: connect to host 10.0.2.15 port 22: Connection refused

i tried to put this in iptables

sudo iptables -I INPUT -p tcp -m tcp --dport 22 -j ACCEPT

but the result doesn’t change…

in sudo iptables -L -n it shows

ACCEPT tcp – 0.0.0.0/0 0.0.0.0/0 tcp dpt:22

systemctl status sshd is running ( active)

i changed the port to 2222

root@host:/home/user# sudo nano /etc/ssh/sshd_config
root@host:/home/user# sudo service ssh force-reload
root@host:/home/user# ssh user@10.0.2.15 -p 2222
ssh: connect to host 10.0.2.15 port 2222: Connection refused

i put the ip and the port in the section of port forwanding in the router

and i changed this sudo nano /etc/tor/torrc i put Socks5Proxy 127.0.0.1:1080 ( is it correct?)

i don’t know what i am missing …

lynx program failing with 'Can't access startfile'?

How to solve 'Connection refused' errors in SSH connection?

ssh: connect to host 127.0.0.1 port 2222: Connection refused

Can you copy/paste your ssh_config and sshd_config files? Both should be edited to reflect the port you’re choosing to use, and if you’re trying to log in as root then your configurations have to be such that that is allowed.

Hi @y010

Could be a uwt issue. This thread may be helpful:

prejudice people would like to create a connection between a workstation vm whonix and my pc, and after I figured out how to do. create a tunnel between my workstatione and a remote server, but before that I'm having trouble, first I would like to confirm that the command ssh remote_username@remote_host remote user is created for the user on the server ssh? in my case FreeSSHd tab users, and remote host is by user name or IP of the machine ?, and here is my question which ip? the inside? if I tr…

hello

thanks for your reply

here we go

This is the ssh client system-wide configuration file. See

ssh_config(5) for more information. This file provides defaults for

users, and the values can be changed in per-user configuration files

or on the command line.

Configuration data is parsed as follows:

1. command line options

2. user-specific file

3. system-wide file

Any configuration value is only changed the first time it is set.

Thus, host-specific definitions should be at the beginning of the

configuration file, and defaults at the end.

Site-wide defaults for some commonly used options. For a comprehensive

list of available options, their meanings and defaults, please see the

ssh_config(5) man page.

hi thanks for your reply

i was searching info and i found this too

Tunnels/Connecting to Tor before a proxy

On the Stream Isolation page, there is a list of applications that are pre-configured to use uwt wrappers. Follow the instructions below in order to disable this.

The following instructions permanently deactivate all uwt wrappers and remove stream isolation for uwt wrapped applications system-wide. Consequently, all uwt wrapped applications revert to the default system networking configuration.

If you want more granular control of uwt wrapper deactivation, see Stream_Isolation#Deactivate_uwt_Stream_Isolation_Wrapper.

Open /etc/uwt.d/50_user.conf in an editor with root rights.

If you are using a graphical Whonix or Qubes-Whonix, run.
[select code]
kdesudo kwrite /etc/uwt.d/50_user.conf

If you are using a terminal-only Whonix, run.
[select code]
sudo nano /etc/uwt.d/50_user.conf

Add.

[select code]
uwtwrapper_global=“0”

Save and exit.

in my case i want to create a connection between gateway and workstation vm ( in the gateway i want to create the tunnel ssh)

[pookie]

Hi!

Something just occurred to me - are you attempting to access Whonix from another VM or from your host machine? Because if you want to SSH to a guest from its host, you’ll have to configure your network a little differently. Someone with more intimate understanding of Whonix will have to chime in and address the potential security concerns of doing this, assuming there are any - I just don’t know enough to say.

[y010]

Hi

Thanks for reply C:

I am trying to connect the gateway and the Workstation with the purpose to redirect the traffic (tunnel ssh+tor )

Both are vm

Well, don’t worry you’re helping me a lot =)

If someone wants to Join the conversation

He/she is welcome

Hi @y010

Unfortunately I can’t offer you much help with this as I do not use SSH with Whonix.

The best advice I can give you would be to remove the Whonix specific part of your question as per https://whonix.org/wiki/Support#Free_Support_Principle .

If you are able to to that you can focus on just getting SSH to connect. You may be able to find more people to help you with that on Unix and Linux Stack Exchange or other Help forums. ; )
