squid won't listen on configured port

Asked by Thomas

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 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 the logfiles was clear. No errors or warnings.

The System is running on xenial and all is uptodate.

thats my cache.log from a start:

If you change to a different port number by running:

sudo vi /etc/squid/squid.conf

Change:
http_port 3128
To:
http_port 3129

Then run:
systemctl restart squid

If you run:
netstat -plant | grep -i squid

Do you see it listening OK?

root@proxy:~# sed 's/http_port 3128/http_port 3129/g' -i /etc/squid/squid.conf
root@proxy:~# grep '^http_port' /etc/squid/squid.conf
http_port 3129

than I stopped squid and made sure, that no squid process is running, before I started the service again.

root@proxy:~# netstat -plant | grep -i squid
root@proxy:~# grep 3129 /var/log/squid/cache.log

# they gives me no output
