Hello list, I am a squid newbie, but i am working on it. So please forgive my lack of knowledge. Sometimes several flash videos don't load or it takes a long time for starting the video. I have read that dns resolution is often a problem for long loading times. But DNS works fine, the squid server isn't busy and the flash browser plugin is up to date. As far as i know squid has a really good debug log. But as long as i don't know what i am searching for, it is not easy for me to identify/solve this problem. Maybe somebody can give me a hint? I am using squid 3 from ubuntu 10.04 repositories, havp as parent proxy and authentication via ADS. It is a virtual machine on vSphere5. 2gb ram, raid 10 for /var/spool/squid3. Here is my squid.conf: cache_mem 64 MB maximum_object_size 10000 KB maximum_object_size_in_memory 128 KB cache_replacement_policy heap LFUDA memory_replacement_policy heap GDSF cache_dir aufs /var/spool/squid3 8000 256 256 dns_nameservers 10.4.1.20 cache_peer localhost parent 8899 0 no-query no-digest url_rewrite_program /usr/bin/squidGuard -c /etc/squid/squidGuard.conf url_rewrite_children 20 cache_effective_user proxy error_directory /usr/share/squid3/errors/de-de auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 20 startup=0 idle=1 auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic auth_param basic children 5 auth_param basic realm Domain Proxy Server auth_param basic credentialsttl 2 hours auth_param basic casesensitive off authenticate_cache_garbage_interval 10 seconds authenticate_ttl 300 seconds external_acl_type nt_group ttl=5 children=5 %LOGIN /usr/lib/squid3/wbinfo_group.pl acl INTERNET_SQUID external nt_group internet acl snmptest snmp_community public acl manager proto cache_object acl localhost src 127.0.0.1/32 acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 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 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 snmp_port 3401 snmp_access allow snmptest localhost snmp_access deny all http_access allow manager localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow localhost http_access allow INTERNET_SQUID http_access deny all icp_access deny all htcp_access deny all http_port 3128 hierarchy_stoplist cgi-bin ? access_log /var/log/squid3/access.log squid cache_log /var/log/squid3/cache.log squid refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern (cgi-bin|\?) 0 0% 0 refresh_pattern . 0 20% 4320 icp_port 0 Thanks a lot and have a good time! -- Marcel
