Nginx - I don`t understand //SOLVED\\

[Kalle13]

Hi,

I want to get wpad support on my pfsense (2.3.2) and I am following this manual https://nguvu.org/pfsense/pfSense-2.3-WPAD-PAC-proxy-configuration-guide/
At the point where I have to test the second nginx instance I get this output

[2.3.2-RELEASE][admin@pfSense.localdomain]/root: /usr/local/sbin/nginx -c /usr/local/etc/nginx/nginx-wpad.conf
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] still could not bind()

After a little research:

Why is nginx listening on port 80?
The option for the web GUI is checked on https  ???
I don`t understand this.
Can anyone give me a hint, please.

Thank you and best regards.

It listens on 80 to offer a redirect to 443. System / Advanced / Admin Access / WebGUI Redirect.

Thank you, that worked for me!  ;D

Best regards.

hi … i also got the same error and have followed the instructions explained before, but still experience the same thing.

The following output results after execution of the code: sockstat -l | grep: 80

[2.4.2-RELEASE][admin@pfSense.mylocal]/root: sockstat -l | grep :80             
www      nginx      97632 7  tcp4   *:80                  *:*
root     nginx      97523 7  tcp4   *:80                  *:*

Just a question :
@christianit:

….

www      nginx      97632 7  tcp4   *:80                  *:*

"www" ??
First time I see nginx running on pfSEnse with such an identity.
For me it's "root" everywhere.

[christianit]

I do not know why the "www" identity can appear other than "root".

and one question

is it correct for the "nginx" folder located in / usr / local / www relating to the nginx-dist folder in the same location? because in the case I experienced like that and does it affect?

thanks.

@christianit:

This isn't 'normal' at all.
Or, actually, it's simple. You think you have a pfSense device, but you don't. It's something else.
Re install completely - and I even advice you not to use the backup of the config.

The problem is in the script "check_proxy_wpad.sh". His must edit, like so:

#!/bin/sh

status=$(/bin/ps -wx | /usr/bin/grep 'nginx-wpad.conf' | sed -e '/grep/d')

if [ "$status" == "" ];then
    /usr/local/sbin/nginx -c /usr/local/etc/nginx/nginx-wpad.conf
else
    exit 0
