Hi Eliezer,

SQUID started listening only after I run "ip6tables -P INPUT ACCEPT". I had searched everywhere on the internet regarding this issue and no one mentioned that IPV6 iptables rules could stop squid from listening on TCP ports. And Squid just started without any complaint. To my limited knowledge, it seems no other software behaves like this?    At first I was indeed suspecting that the issue is related to IPV6. I had tried recompiling SQUID without IPV6 and disabed IPV6 using sysctl.conf, nothing worked. It never occured to me that my IPV6 INPUT POLICY could be the culprit.
  Again, many thanks for your help
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

root@host8d66c97880:~# netcat -v -l -4 34568
Listening on 0.0.0.0 34568
^C
root@host8d66c97880:~# netcat -v -l -6 34568
Listening on :: 34568

I configured it to listen on 34568


netcat -v -l -6 4444
netcat -v -l -4 4444
