If your SSH proxy connection is going to be used often, you don't have to pass them as parameters each time. you can add the following lines to <code>~/.ssh/config</code>
<pre><code>Host foobar.example.com
 ProxyCommand nc -X connect -x proxyhost:proxyport %h %p
 ServerAliveInterval 10
</code></pre>
then to connect use
<pre><code>ssh foobar.example.com

I was using the following lines in my <code>.ssh/config</code> (which can be replaced by suitable command line parameters) under Ubuntu

<pre><code>Host remhost
 HostName my.host.com
 User myuser
 ProxyCommand nc -v -X 5 -x proxy-ip:1080 %h %p 2&gt; ssh-err.log
 ServerAliveInterval 30
 ForwardX11 yes

When using it with Msys2, after installing <code>gnu-netcat</code>, file <code>ssh-err.log</code> showed that option <code>-X</code> does not exist. <code>nc --help</code> confirmed that, and seemed to show that there is no alternative option to handle proxies.

So I installed <code>openbsd-netcat</code> (<code>pacman</code> removed <code>gnu-netcat</code> after asking, since it conflicted with <code>openbsd-netcat</code>). On a first view, and checking the respective man pages, <code>openbsd-netcat</code> and Ubuntu <code>netcat</code> seem to very similar, in particular regarding options <code>-X</code> and <code>-x</code>.
With this, I connected with no problems.

This is how I solved it, hoping to help others later.
My system is debian 10, and minimal installation.
I also have the same problem like this.
<pre><code>git clone git@github.com:nothing/nothing.git
Cloning into 'nothing'...
nc: invalid option -- 'x'
nc -h for help
ssh_exchange_identification: Connection closed by remote host
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
</code></pre>
Or
<pre><code>git clone git@github.com:nothing/nothing.git
Cloning into 'nothing'...
/usr/bin/nc: invalid option -- 'X'
nc -h for help
ssh_exchange_identification: Connection closed by remote host
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
</code></pre>
So, I know the nc has different versions like <code>openbsd-netcat</code> and <code>GNU-netcat</code>, you can change the nc in debian to the openbsd version, but I choose to change the software like <code>corkscrew</code>, because the names of the two versions of nc in system are same, and many people don’t understand it well. My approach is as follows.
<pre><code>sudo apt install corkscrew
</code></pre>
Then.
<pre><code>vim ~/.ssh/config
</code></pre>
Change this file like this.
<pre><code>Host github.com
 User git
 ProxyCommand corkscrew 192.168.1.22 8118 %h %p
</code></pre>
<code>192.168.1.22</code> and <code>8118</code> is my proxy server's address and port, you should change it according to your server address.
It's work fine.

I am trying to connect to my virtual server through a proxy but I can't connect, it just hangs. I'm assuming this is because it's not getting through our proxy.

I have tried exactly the same thing at home and it works perfectly. I'm on OSX using Terminal to connect.

Can anyone advise me how I can get through the proxy with SSH?

Connect with SSH through a proxy

虚拟服务器

服务器

CentOS

Ubuntu

我不知道我在这里做什么，所以如果你能帮助我，请记住这一点！我正在尝试通过代理连接到我的虚拟服务器，但我无法连接，它只是挂起。我猜这是因为它没有通过我们的代理。我在家里也试过完全一样的方法，而且效果很好。我在OSX上使用终端连接。有人能告诉我如何通过SSH的代理吗？
