Nginx shellinabox proxy_pass

Hello,

I am trying to get nginx to work with shellinabox. I guess what I am really having trouble with is proxy_pass, such that when I enter the URL;

http://mydomain/shell

It loads the shellinabox page from port 4200. I used to have this working with Apache but cannot figure it out with Nginx.

At present I have created a server block which I have been playing around with, but I havent been able to get any response from it;

server {
 server_name shell;
 listen 80;
 listen   [::]:80;
 location ~ ^/shell/ {
    proxy_pass http://localhost:4200;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 }
}

The reason I need this is because my office blocks port 6789 . . . . so I need to access it through the /shell sub URL if I want to access my CLI from work - which I don sometimes if things go wrong.

Does anyone have a solution for this?

Thanks for the response. I had seen, read and played around with the ideas in your post but without success. I just had a bit of a play around again with to dig into the problem a bit further.

I can specify 1 x server block, for example, shellinabox and get this to work. When I then specify another, for example, nzbget then nzbget will work but shellinabox will not. Looking at the logs leads me to believe that the server blocks Im specifying are conflicting with each other. I see error messages like;

2014/10/12 16:31:59 [error] 4808#0: *4 open() "/var/www/shell" failed (2: No such file or directory), client: 192.168.2.3, server: rutorrent, request: "GET /shell HTTP$l HTTP/1.1", host: "192.168.2.20"

Which shows that the rutorrent server block is trying to resolve for http://mydomain/shell (i.e. shellinabox)???

Here is the rutorrent server block (which is working) is there something I cant see in it that is specifying it to be a default for other server blocks?

server {
   server_name rutorrent;
   #listen 80;


    location / {
        root /var/www;
        index index.php index.html;
    }


    location /RPC1 {
        include /etc/nginx/scgi_params;
        scgi_pass backend2;
    }


    location ~  \.php$ {
        # Filter out arbitrary code execution
        location ~ \..*/.*\.php$ {return 404;}


        include /etc/nginx/fastcgi_params;
        fastcgi_param SCRIPT_FILENAME /var/www$fastcgi_script_name;
        fastcgi_index index.php;
        fastcgi_pass  backend;
    }


    location ~ /\.ht {
        deny  all;
    }
}


upstream backend {
    server unix:/var/run/php5-fpm.sock;
}


upstream backend2 {
    server unix:/tmp/rpc.socket;
}

In my sites-enabled I have the following files; default, openmediavault-webgui, rutorrent, shell, nzbget. I can only get one of rutorrent, shell, nzbget to go at any given time. . . . i.e. I need to un-symlink rutorrent and nzbget to get shell to work etc.

Very confused.
