# If your apt-cacher machine is directly exposed to the Internet and you are
# worried about unauthorised machines fetching packages through it, you can
# specify a list of IPv4 addresses which are allowed to use it and another
# list of IPv4 addresses which aren't.
# Localhost (127.0.0.1) is always allowed. Other addresses must be matched
# by allowed_hosts and not by denied_hosts to be permitted to use the cache.
# Setting allowed_hosts to "*" means "allow all".
# Otherwise the format is a comma-separated list containing addresses,
# optionally with masks (like 10.0.0.0/22), or ranges of addresses (two
# addresses separated by a hyphen, no masks, like '192.168.0.3-192.168.0.56').
allowed_hosts=10.0.0.0/24
denied_hosts=*
# And similarly for IPv6 with allowed_hosts_6 and denied_hosts_6.

# w.x.y.z and are handled as IPv4.

# This thing can be done by Apache but is much simpler here - limit access to

# Apt-cacher can generate usage reports every 24 hours if you set this
# directive to 1. You can view the reports in a web browser by pointing
# to your cache machine with '/apt-cacher/report' on the end, like this:
# http://yourcache.example.com/apt-cacher/report
# Generating reports is very fast even with many thousands of logfile
# lines, so you can safely turn this on without creating much
# additional system load.
generate_reports=1
# Apt-cacher can clean up its cache directory every 24 hours if you set
# this directive to 1. Cleaning the cache can take some time to run
# (generally in the order of a few minutes) and removes all package
# files that are not mentioned in any existing 'Packages' lists. This
# has the effect of deleting packages that have been superseded by an
# updated 'Packages' list.
clean_cache=1
# Apt-cacher can be used in offline mode which just uses files already cached,
# but doesn't make any new outgoing connections by setting this to 1.
offline_mode=0
# The directory to use for apt-cacher access and error logs.
# The access log records every request in the format:
# date-time|client ip address|HIT/MISS/EXPIRED|object size|object name
# The error log is slightly more free-form, and is also used for debug
# messages if debug mode is turned on.
# Note that the old 'logfile' and 'errorfile' directives are
# deprecated: if you set them explicitly they will be honoured, but it's
# better to just get rid of them from old config files.
logdir=/var/log/apt-cacher
# apt-cacher can use different methods to decide whether package lists need to
# be updated,
# A) looking at the age of the cached files
# B) getting HTTP header from server and comparing that with cached data. This
# method is more reliable and avoids desynchronisation of data and index files
# but needs to transfer few bytes from the server every time somebody requests
# the files ("apt-get update")
# Set the following value to the maximum age (in hours) for method A or to 0
# for method B
expire_hours=0
# Apt-cacher can pass all its requests to an external http proxy like
# Squid, which could be very useful if you are using an ISP that blocks
# port 80 and requires all web traffic to go through its proxy. The
# format is 'hostname:port', eg: 'proxy.example.com:8080'.
#http_proxy=proxy.example.com:8080
# Use of an external proxy can be turned on or off with this flag.
# Value should be either 0 (off) or 1 (on).
use_proxy=0
# External http proxy sometimes need authentication to get full access. The
# format is 'username:password'.
#http_proxy_auth=proxyuser:proxypass
# Use of external proxy authentication can be turned on or off with this flag.
# Value should be either 0 (off) or 1 (on).
use_proxy_auth=0
# This sets the interface to use for the upstream connection.
# Specify an interface name, an IP address or a host name.
# If unset, the default route is used.
#interface=
# Rate limiting sets the maximum bandwidth in bytes per second to use
# for fetching packages. Syntax is fully defined in 'man wget'.
# Use 'k' or 'm' to use kilobytes or megabytes / second: eg, 'limit=25k'.
# Use 0 or a negative value for no rate limiting.
limit=0
# Debug mode makes apt-cacher spew a lot of extra debug junk to the
# error log (whose location is defined with the 'logdir' directive).
# Leave this off unless you need it, or your error log will get very
# big. Acceptable values are 0 or 1.
debug=0
# To enable data checksumming, install libberkeleydb-perl and set this option
# to 1. Then wait until the Packages/Sources files have been refreshed once
# (and so the database has been built up). You can also nuke them in the cache
# to trigger the update.
# checksum=1
# Print a 410 (Gone) HTTP message with the specified text when accessed via
# CGI. Useful to tell users to adapt their sources.list files when the
# apt-cacher server is being relocated (via apt-get's error messages while
# running "update")

#cgi_advise_to_use = Server relocated. To change sources.list, run perl -pe "s,/apt-cacher\??,:3142," -i /etc/apt/sources.list
# Server mapping - this allows to hide real server names behind virtual paths
# that appear in the access URL. This method is known from apt-proxy. This is
# also the only method to use FTP access to the target hosts. The syntax is
# simple, the part of the beginning to replace, followed by a list of mirror
# urls, all space separated. Multiple profile are separated by semicolons
# Note that you need to specify all target servers in the allowed_locations
# options if you make use of it. Also note that the paths should not overlap
# each other. FTP access method not supported yet, maybe in the future.

# Permitted Index files - this is the perl regular expression which matches all
# index-type files (files that are uniquely identified by their full path and
