I would like to send all my IMAP client authentication to IMAP backend server via NGINX IMAP proxy server. I want to know how I can bypass auth_http script or tell the script to complete the authentication process forward directly to backend server.
Is there any workaround to acomplish this task? I'd appreciate if someone guide me with this.
I have used auth.php module that is available on NGINX official site.
file location: var/www/html/auth.php
And in nginx.conf
mail { auth_http localhost/auth.php server_name proxy.domain.com //my server name is different }

I know it can go to a local port with proxy_pass, and there's also stuff like FastCGI and wsgi. Is there a list of these ways nginx can send requests to my server?
I have configured a simple NGINX reverse proxy to use with TFS client for code check-in and checkouts and create build piplelines using Azure DevOps. The nginx proxy is configured on a cloud VM and TFS is located in om-prem data center so the requests comes to tfs via VPN tunnel. But we are getting multiple errors like:
Technical information (for administrator):
HTTP code 413: Request Entity Too Large
D:\TFS\abc\Demo Project 9\Source Code\AES\packages\Microsoft.ApplicationInsights.DependencyCollector.2.8.1\content\ApplicationInsights.config.transform: TF30063: You are not authorized to access nginx/1.14.0 (Ubuntu).
Here is my proxy:
server {
listen 8080;
location / {
proxy_pass http://10.x.x.0:8080/tfs
}
}
Nginx can't handle NTLM authentication properly.
As a workaround, you could try to write a pure reverse proxy with socket in NodeJS.
More detail about this, take a look at here: How to reverse proxy a TFS server
I have an NGINX Server set up, I'd like to take a request and forward it to another application on a TCP port.
Let's say I have the following JSON payload
{
"someKey1": 1234,
"someKey2": "a string"
}
This is sent inside query parameters like the following
https://mywebsite.com?payload=%7B%0A%20%22someKey1%22%3A%201234%2C%0A%20%22someKey2%22%3A%20%22a%20string%22%0A%7D
Is there a way to forward that JSON payload to TCP port 1234 natively with NGINX?
Additionally, can I do any pre-processing of the above payload prior to it being forwarded to TCP port 1234. For example, I'd like to covert the above JSON to
someKey1=1234,someKey2="a string"
And then forward this data to TCP port 1234
I understang I'd have to create some sort of REST endpoint using something like springboot to do this, but I'd really like to try and accomplish the above natively with NGINX if possible.
Nginx's primary purpose is HTTP server/proxy.
It can be scripted via ngx_http_lua_module, but for your task it is much simpler to make an app/microservice that will listen HTTP and forward your custom protocol, or modify your app that listens mentioned port to understand HTTP.
When your endpoint talks HTTP - nginx can then be used for routing:
location /some_path/ {
proxy_pass http://localhost:1234/;
}
location /some_other_path/ {
proxy_pass http://localhost:1235/;
}
NGINX is simple web-server, which accepts HTTP requests and forwards them to configured location (may be application server, or any other web-server), and responds back on HTTP to the requester. Data can't be processed inside NGINX.
You can configure forwarding rules in default file under sites-available directory in NGINX installation directory.
Here is the nice tutorial of NGINX configuration which might help you.
I'm trying to setup an FTP subdomain, such that all incoming SFTP requests to (say) ftp.myname.com, get routed to a particular internal server, (say) 10.123.456 via port 22.
How do I use nginx to route this traffic?
I've already setup the SFTP server, and can SFTP directly to the server, say:
sftp username#123.456.7890, which works fine.
The problem is that when I setup nginx to route all traffic to ftp.myname.com, it connects, but the passwords get rejected. I have no problems routing web traffic to my other subdomains, say dev.myname.com (with passwords), but it doesn't work for the SFTP traffic:
server {
listen 22;
server_name ftp.myname.com;
return .............
}
How do I define the return sting to route the traffic with the passwords?
The connection is SFTP (via port 22).
Thanks
Aswering to #peixotorms: yes, you can. nginx can proxy/load balance http as well as tcp and udp traffic, see nginx stream modules documentation (at the nginx main documentation page) , and specifically the stream core module's documentation.
You cannot do this on nginx (http only), you must use something like HaProxy and a simple dns record for your subdomain pointing to the server ip.
Some info: http://jpmorris-iso.blogspot.pt/2013/01/load-balancing-openssh-sftp-with-haproxy.html
Edit:
Since nginx version 1.15.2 it's now possible to do that using the variable $ssl_preread_protocol. The official blog added post about how to use this variable for multiplexing HTTPS and SSH on the same port.
https://www.nginx.com/blog/running-non-ssl-protocols-over-ssl-port-nginx-1-15-2/
Example of configuring SSH on an upstream block:
stream {
upstream ssh {
server 192.0.2.1:22;
}
upstream sslweb {
server 192.0.2.2:443;
}
map $ssl_preread_protocol $upstream {
default ssh;
"TLSv1.2" sslweb;
}
# SSH and SSL on the same port
server {
listen 443;
proxy_pass $upstream;
ssl_preread on;
}
}
I just tried with http ans https to fetch data in the for of json from server, while I try with http its working fine but when I try with https getting error. Is there any way to handle "https" request if server is not cofigured with SSL.
no, there isn't any way if the server isn't configured to user SSL. However if you want TLS encryption you could use a SSH tunnel. If you can't configure your application to use SSL you could configure a http server like Apache or nginx to act as an SSL Proxy.
