ftp on a subdomain?

[Nineballo]

Is it possible to host an ftp server on a subdomain such as ftp.example.com, either using some weird Nginx config or something else.

 

I'm hosting the ftp server on Ubuntu server 18 with vsftpd

 

i tried doing a reverse proxy with nginx and ended up with the whole ftp not supported thing...

This was the config I tried, its just a modified version of the one I use for http.

 

server {
  listen 80;
  listen 443;
  server_name ftp.nineball.wtf;
  location / { # Or / if hosting at the root.
      proxy_pass ftp://0.0.0.0/;
      proxy_set_header Host $host;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection upgrade;
      proxy_set_header Accept-Encoding gzip;
  }
}

It results in this error when restarting nginx

I think someone has a proxy that will let you pass ftp traffic. Did you try that?

[Nineballo]

Nope but I will right now, was hoping for an nginx solution or even a dns solution (if that's a thing).

dns can do it, but would point to anouther ip, do you have multiple ips to use?

 

I found this that might work https://github.com/yaoweibin/nginx_tcp_proxy_module

i have two but i wanna keep everything on that main server. I was experimenting with the proxy thing but i couldn't figure it out. I was experimenting with the built in proxy tcp thingy.

If you have 2, you can point both to the server with the router and port forwarding and nat. What is your network setup?

[Nineballo]

a vps and and a small computer behind my home router

I run everything through cloudflare

Also my networking knowledge is awful so heads up you might have to explain things a little...

A friend solved this for me... all it took was an A record with the ftp:// prefix.
