Recently upgraded to Raspbian Buster and squid 4.6. Since then I am unable to cache the Packages.xz that apt uses. The various other Pis using this proxy all end up downloading the 30MB Packages.xz every time. Does anyone have any suggestions on how to get it to cache? Cheers MarkJ squid -v Squid Cache: Version 4.6 Service Name: squid Raspbian linux access.log 1563597855.786 605 192.168.1.73 TCP_REFRESH_UNMODIFIED/200 15306 GET http://raspbian.raspberrypi.org/raspbian/dists/buster/InRelease - HIER_DIRECT/93.93.128.193 - 1563597855.811 620 192.168.1.73 TCP_REFRESH_UNMODIFIED/200 25429 GET http://archive.raspberrypi.org/debian/dists/buster/InRelease - HIER_DIRECT/93.93.128.133 - 1563597857.486 620 192.168.1.73 TCP_REFRESH_UNMODIFIED/200 205801 GET http://archive.raspberrypi.org/debian/dists/buster/main/binary-armhf/Packages.gz - HIER_DIRECT/93.93.128.133 application/x-gzip 1563597936.436 80026 192.168.1.73 TCP_MISS_ABORTED/200 2641974 GET http://raspbian.raspberrypi.org/raspbian/dists/buster/main/binary-armhf/Packages.xz - HIER_DIRECT/93.93.128.193 application/x-xz config file acl localnet src 192.168.1.0/24 # internal network acl localnet src fc00::/7 # RFC 4193 local private network range acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl l500-020b src 192.168.1.20 acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT acl ads dstdomain .ad1.pamedia.com.au acl ads dstdomain .ad3.pamedia.com.au acl ads dstdomain .adevents.com.au acl ads dstdomain .adinfinity.com.au acl ads dstdomain .ads.excitehome.net.au acl ads dstdomain .ads.fairfax.com.au acl ads dstdomain .ads.godaddy.com acl ads dstdomain .ads.google.com acl ads dstdomain .ads.ninemsn.com.au acl ads dstdomain .ads.optusnet.com.au acl ads dstdomain .ads.property.com.au acl ads dstdomain .ads.youtube.com acl ads dstdomain .adserver.news.com.au acl ads dstdomain .au.adserver.yahoo.com acl ads dstdomain .doubleclick.net acl ads dstdomain .googleadservices.com acl ads dstdomain .zoomdirect.com.au acl malware dstdomain am10.ru acl malware dstdomain deepspacer.com acl malware dstdomain trafficconverter.biz acl malware dstdomain .eu.interia.pl acl malware dstdomain .expo9.exponential.com acl malware dstdomain .flashtalking.com acl malware dstdomain .funad.co.kr acl malware dstdomain .luckytime.co.kr acl malware dstdomain .trafficholder.com acl malware2 dst 96.43.128.194 acl hiddenwasp dst 103.206.122.245 acl hiddenwasp dst 103.206.123.13 acl hiddenwasp2 dstdomain http://103.206.123.13 http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access deny ads http_access deny malware http_access deny malware2 http_access deny hiddenwasp http_access deny hiddenwasp2 http_access allow l500-020b manager http_access deny manager http_access allow localnet http_access allow localhost http_access deny all http_port 3128 cache_mem 448 MB maximum_object_size 320 MB memory_replacement_policy lru cache_replacement_policy heap LFUDA cache_dir aufs /var/spool/squid 18432 32 256 quick_abort_min -1 KB client_request_buffer_max_size 128 KB coredump_dir /var/spool/squid access_log /var/log/squid/access.log squid cache_log /var/log/squid/cache.log logfile_rotate 7 netdb_filename none refresh_pattern (\.deb|\.udeb)$ 1440 80% 10080 refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 host_verify_strict on max_filedescriptors 1200 dns_v4_first on pinger_enable off shutdown_lifetime 5 seconds _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
