[squid-users] SQUID refuses to listen on any TCP Port

[Eliezer Croitoru]

Hey Ben,

The next step in this situation is to try and connect with netcat from a
remote host and also locally.
>From what I understood the issue was a firewall issue so Squid was
listening.
I can also assume that squid was listening.
Just For future reference:
Try to run the next commands:
sudo netstat -ntlp
sudo ss -ntlp

and send their output to us.
In ubuntu you will not see any "squid" when running plain netstat or ss.

All The Bests,
Eliezer

Hello,

It looks like that if I start installing it right after OS installation, 
it works. But not if I install any packages, for example, make, 
gcc,strongswan and so on. once it stop working, it will not work anymore 
even if I remove all aforementioned packages. reboot also doesn't help. 
I also tried it on Debian 11. no luck either! it only works in old ubuntu 16
I can be 100% sure that squid is not listening on any TCP ports. running 
these commands looks fine

Thanks for your being patient and kind

Listening on 0.0.0.0 34568
^C
root at host8d66c97880:~# netcat -v -l -6 34568
Listening on :: 34568

I configured it to listen on 34568
