New question #680111 on Ubuntu: https://answers.launchpad.net/ubuntu/+question/680111
I can't get squid to listen on port 3128. I see in cache.log the following line: 2019/04/08 07:38:48 kid1| Accepting HTTP Socket connections at local=[::]:3128 remote=[::] FD 11 flags=9 but the port seams not to listen: root@proxy:~# netstat -naptu|grep 3128 gives me no output - btw. with grep squid I only get: root@proxy:~# netstat -naptu|grep squid udp 0 0 0.0.0.0:40325 0.0.0.0:* 922/(squid-1) udp6 0 0 ::1:55086 ::1:56111 VERBUNDEN 922/(squid-1) udp6 0 0 ::1:56111 ::1:55086 VERBUNDEN 922/(squid-1) udp6 0 0 :::41648 :::* 922/(squid-1) What I have done to so far, to find/fix the problem: a) apt --reinstall install squid squid-common squid-langpack b) extracted the default squid.conf from deb and used them. c) checked logfiles cache.log and syslog (last one filtered to squid and port 3128) d) checked systemctl status squid.service e) stopped squid, runned "rm -rv /var/spool/squid/*", started squid all was running without errors and logfiles was clear. No errors or warnings. thats my cache.log from a start: 2019/04/08 10:20:01 kid1| Set Current Directory to /var/spool/squid 2019/04/08 10:20:01 kid1| Starting Squid Cache version 3.5.12 for
