[CentOS] Squid as interception HTTPS proxy under CentOS 7

Hi all,

I am trying to configure squid as a interception HTTPS proxy under CentOS 7. At every https request, I am receiving a certificate error.

My current config for squid is:

# My localnet acl localnet src 172.22.55.0/28 acl localnet src 172.22.58.0/29

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

# # Recommended minimum Access Permission configuration: # # Deny requests to certain unsafe ports http_access deny !Safe_ports

# Deny CONNECT to other than secure SSL ports http_access deny CONNECT !SSL_ports

# Only allow cachemgr access from localhost http_access allow localhost manager http_access deny manager

# We strongly recommend the following be uncommented to protect innocent # web applications running on the proxy server who think the only # one who can access services on "localhost" is a local user #http_access deny to_localhost

# # INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS #

# Example rule allowing access from your local networks. # Adapt localnet in the ACL section to list your (internal) IP networks # from where browsing should be allowed http_access allow localnet http_access allow localhost

# And finally deny all other access to this proxy http_access deny all

# Squid normally listens to port 3128 #http_port 3128

# Uncomment and adjust the following to add a disk cache directory. #cache_dir ufs /var/spool/squid 100 16 256

# Leave coredumps in the first cache dir coredump_dir /var/spool/squid

# # Add any of your own refresh_pattern entries above these. # 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

# My custom configuration http_port 8079 http_port 8080 intercept https_port 8081 ssl-bump intercept generate-host-certificates=on dynamic_cert_mem_cache_size=4MB key=/etc/squid/custom.private cert=/etc/squid/custom.cert

# Anonymous proxy forwarded_for off request_header_access Allow allow all request_header_access Authorization allow all request_header_access WWW-Authenticate allow all request_header_access Proxy-Authorization allow all request_header_access Proxy-Authenticate allow all request_header_access Cache-Control allow all request_header_access Content-Encoding allow all request_header_access Content-Length allow all request_header_access Content-Type allow all request_header_access Date allow all request_header_access Expires allow all request_header_access Host allow all request_header_access If-Modified-Since allow all request_header_access Last-Modified allow all request_header_access Location allow all request_header_access Pragma allow all request_header_access Accept allow all request_header_access Accept-Charset allow all request_header_access Accept-Encoding allow all request_header_access Accept-Language allow all request_header_access Content-Language allow all request_header_access Mime-Version allow all request_header_access Retry-After allow all request_header_access Title allow all request_header_access Connection allow all request_header_access Proxy-Connection allow all request_header_access User-Agent allow all request_header_access Cookie allow all request_header_access All deny all

# SSL Bump Config always_direct allow all ssl_bump server-first all sslproxy_cert_error deny all sslproxy_flags DONT_VERIFY_PEER

I have tried disabling "sslproxy_cert_error" and "sslproxy_flags" directives, without luck.

Any ideas about what am I doing wrong?

Thanks.
