Hi I am trying to build a squid that runs ssl_bump and icap to allow me to write a keyword filter for the kids that will cover ssl pages. I have ssl_bump working and my icap client is also happily talking to squid. for testing currently I have the icap disabled and I am just focusing on the ssl_bump functions. I have built squid as follows: Squid Cache: Version 3.4.3 configure options: '--prefix=/usr' '--includedir=/usr/include' '--datadir=/usr/share' '--bindir=/usr/sbin' '--libexecdir=/usr/lib/squid3' '--localstatedir=/var' '--sysconfdir=/etc/squid3' '--disable-snmp' '--enable-delay-pools' '--enable-ssl' '--enable-ssl-crtd' '--enable-linux-netfilter' '--enable-eui' '--enable-icap-client' '--enable-gnuregex' and set up the conf file as shown at the end of the message. when I use the proxy and go to http://news.google.com everything is fine and it all works OK when I go to https://news.google.com some elements (mainly graphics and thumbnails) fail to load and I get log entries like this 2014/02/08 23:27:55.237| url.cc(386) urlParse: urlParse: Split URL 'ssl.gstatic.com:443' into proto='', host='ssl.gstatic.com', port='443', path='' 2014/02/08 23:27:55.237| HttpHeader.cc(407) HttpHeader: init-ing hdr: 0x9908538 owner: 2 2014/02/08 23:27:55.237| HttpRequest.cc(70) HttpRequest: constructed, this=0x9908528 id=56 2014/02/08 23:27:55.237| Address.cc(369) lookupHostIP: Given Non-IP 'ssl.gstatic.com': Name or service not known 2014/02/08 23:27:55.237| HttpHeader.cc(557) parse: parsing hdr: (0x9908538) User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:25.0) Gecko/20100101 Firefox/25.0 Proxy-Connection: keep-alive Connection: keep-alive Host: ssl.gstatic.com if I do a lookup on the ssl.gstatic.com my local DNS (dnsmasq on the squid host) returns a valid address straight away. it also fails on 2014/02/08 23:27:54.623| peer_select.cc(265) peerSelectDnsPaths: Find IP destination for: news.google.com:443' via news.google.com 2014/02/08 23:27:54.623| ipcache.cc(647) ipcache_nbgethostbyname: ipcache_nbgethostbyname: Name 'news.google.com'. 2014/02/08 23:27:54.623| Address.cc(369) lookupHostIP: Given Non-IP 'news.google.com': Name or service not known 2014/02/08 23:27:54.623| ipcache.cc(695) ipcache_nbgethostbyname: ipcache_nbgethostbyname: MISS for 'news.google.com' And this is odd because it loads the page in the first place. I have also tried a build with --disable-internal-dns and get the same result (but I still use the local dnsmasq) Does this hit any chords with anyone? thanks in advance.
