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 _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
