Hi list, Since I upgraded the OS to CentOS 7.2 and Squid to 3.5.12 (RPM from www1.ngtech.co.il the local squidclient gets no answer if pointed to localhost: # squidclient -v -p 3128 mgr:info Request: GET cache_object://localhost/info HTTP/1.0 Host: localhost User-Agent: squidclient/3.5.12 Accept: */* Connection: close . ERROR: Cannot connect to [::1]:3128 Same with IPv4: # squidclient -v -h 127.0.0.1 -p 3128 mgr:info Request: GET cache_object://127.0.0.1/info HTTP/1.0 Host: 127.0.0.1 User-Agent: squidclient/3.5.12 Accept: */* Connection: close . According to netstat squid is listening: # netstat -tlpn Aktive Internetverbindungen (Nur Server) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 927/sshd tcp 0 0 0.0.0.0:3128 0.0.0.0:* LISTEN 1373/(squid-9) tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1814/master tcp6 0 0 :::80 :::* LISTEN 923/httpd tcp6 0 0 :::22 :::* LISTEN 927/sshd tcp6 0 0 ::1:25 :::* LISTEN 1814/master Even there it is strange that it does not listen anymore on IPv6 even if there was no change in the config file. The relevant part looks like this: http_port 0.0.0.0:3128 http_port [::]:3128 http_port [::1]:3128 Aside this squidclient problem everything runs fine. Any idea?
