Hi, I've been trying to use a SSL connection to an parent squid proxy, and the child squid always fails even I specifically asked it to stop verifying stuff here's the relevant config on child sslproxy_cert_error allow all sslproxy_flags DONT_VERIFY_PEER,DONT_VERIFY_DOMAIN cache_peer x.x.x.x parent 8443 0 no-digest no-query default ssl sslflags=DONT_VERIFY_PEER,DONT_VERIFY_DOMAIN,NO_DEFAULT_CA sslcert=ssl.pem sslkey=ssl.key and this appears in the cache.log 2012/03/03 02:50:51| fwdNegotiateSSL: Error negotiating SSL connection on FD 11: error:00000000:lib(0):func(0):reason(0) (5/-1/104) I've verified the parent side works fine, in fact, the server side has been implemented using stunnel and it works fine if I setup stunnel in local and tunnel squid through it. Cheers.
