value pair input squid.conf

youngsuh — Tue, 29 Jun 2021 17:34:12 GMT

Has anyone extracted the value pair squid.conf file to create a list of approve vs block URLs?

Here is sourcetype that I was able to adjust

CHARSET=UTF-8
DATETIME_CONFIG=CURRENT
SHOULD_LINEMERGE=false
category=Structured
description=A variant of the conf source type, with support for nonexistent timestamps
disabled=false
pulldown_type=true
LINE_BREAKER=([\r\n]+)

Here is the sample input: (masked host and IP for security)

# log_mime_hdrs on

# Turn off caching
cache deny all

# Disable ICMP pinger
pinger_enable off

# Consult local hosts file
# hosts_file /etc/hosts

# Set squid pidfile location
pid_filename /var/run/squid/squid.pid

# Set squid access logging location and use more human-readable format
access_log stdio:/var/log/squid/access_combined.log logformat=combined
access_log daemon:/var/log/squid/access_default.log logformat=squid

# Set cache logging location
cache_log /var/log/squid/cache.log

After thinking thru the process. squid.conf would have approve and deny list of traffic in the configuration. So, you would only need a section of .conf file parse instead of trying to parse all the fields. here is the regex used to parse and build the lookup to monitor squid access logs for what's outside the approve and deny traffic.

^acl\s(?P<acl_name>[^.\s]+)\s+\w+\s(?P<dest_domain>[-a-zA-Z0-9@:%._\+~#=]{1,256})
