Hello, I used external helper with squid 3.5.xx several years without any problem. Now I tried to upgrade to squid 4.0.21 and squid seems to work fine, but I get many logentries like: --snip-- 2017/09/14 07:43:12 kid3| WARNING: blockhostsdomain ACL is used in context without an ALE state. Assuming mismatch. 2017/09/14 07:43:12 kid3| WARNING: blockhostsip ACL is used in context without an ALE state. Assuming mismatch. 2017/09/14 07:44:12 kid4| WARNING: blockhostsdomain ACL is used in context without an ALE state. Assuming mismatch. 2017/09/14 07:44:12 kid4| WARNING: blockhostsip ACL is used in context without an ALE state. Assuming mismatch. --snip-- when I switched the acls to a file list, the warnings are gone. my acls for external helpers look like: external_acl_type blockhostiptype ttl=3600 negative_ttl=3600 grace=50 children-max=10 children-startup=2 %DST /usr/bin/dnsbl-ip.pl bl acl blockhostsip external blockhostiptype external_acl_type blockhostdomaintype ttl=3600 negative_ttl=3600 grace=50 children-max=10 children-startup=2 %DST /usr/bin/dnsbl.pl dbl acl blockhostsdomain external blockhostdomaintype when I replaced to above lines with this two, the warnings are gone: acl blockhostsip dst "/etc/squid/blockhosts.ips" acl blockhostsdomain dstdomain "/etc/squid/blockhosts.domains" but I want to use the external helpers, because the lists were updated many times a day and a reconfigure of squid has an impact of 2-3 seconds. As I said before, squid works fine and checks the acls, but I get many warnings in the cache.log and don't know the cause of it. -- Regards Dieter -- I do not get viruses because I do not use MS software.
