+# This is the config file for apt-cacher. On most Debian systems you can safely #

+# Commented defaults or examples are given. They can be changed here, or        #
+# overridden using a fragment placed in ./conf.d/                               #
+#################################################################################
+
+### GENERAL ###
+
+# The location of the local cache/working directory. This can become quite
+# large, so make sure it is somewhere with plenty of space.
+#
+#cache_dir = /var/cache/apt-cacher
+
+# The directory to use for apt-cacher access and error logs.
+# The access log records every request in the format:
+#
+#  date-time|PID|client IP address|HIT/HEAD/MISS/EXPIRED/NOTMOD|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.
+#
+#log_dir = /var/log/apt-cacher
+
+# The email address of the administrator is displayed in the info page and
+# traffic reports.
+#
+admin_email = {{ apt_cacher.get('admin_email', 'root@localhost') }}
+
+# Daemon port setting, only useful in stand-alone mode. You need to run the
+# daemon as root to use privileged ports (<1024).
+#
+# For standalone daemon auto startup settings please edit the file
+# /etc/default/apt-cacher.
+#
+#daemon_port = 3142
+
+# Optional settings, user and group to run the daemon as. Make sure they have
+# sufficient permissions within the cache and log directories. Comment the
+# settings to run apt-cacher as the invoking user.
+#
+group = www-data
+user = www-data
+
+# optional setting, binds the listening daemon to specified IP(s).
+#
+#daemon_addr = localhost
+
+# 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 = 1
+
+# 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 delete them from the cache to
+# trigger the database update.
+#
+#checksum = 1
+
+# Importing checksums from new index files into the checksum database can cause
+# high CPU usage on slower systems. This option sets a limit to the number of
+# index files that are imported simultaneously, thereby limiting CPU load
+# average, but, possibly, taking longer. Set to 0 for no limit.
+#
+#concurrent_import_limit = 1
+
+# CGI mode is deprecated.
+#
+# Send 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 = Please use http://cacheserver:3142/ as apt-cacher access URL
+#cgi_advise_to_use = Server relocated. To change sources.list, run 
+# perl -pe "s,/apt-cacher??,:3142," -i /etc/apt/sources.list
+#
+# To further facilitate migration from CGI to daemon mode this setting will
+# automatically redirect incoming CGI requests to the specified daemon URL.
+#
+#cgi_redirect = http://localhost:3142/
+
+### UPSTREAM PROXY ###
+
+# 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
+
+# External http proxy sometimes need authentication to get full access. The
+# format is 'username:password'.
+#
+#http_proxy_auth = proxyuser:proxypass
+
+# Use of the configured external proxy can be turned on or off with this flag.
+# Value should be either 0 (off) or 1 (on).
+#
+#use_proxy = 0
+
+# 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 = eth0
+
+# Rate limiting sets the maximum bandwidth in bytes per second to use for
+# fetching packages.  Use 0 value for no rate limiting.
+#
+#limit = 0
+
+### ACCESS and SECURITY ###
+
+# Server mapping - this allows mapping virtual paths that appear in the access
+# URL to real server names. The syntax is the part of the beginning of the URL
+# to replace (the key), followed by a list of mirror URLs, all space
+# separated. Multiple mappings are separated by semicolons or commas, as
+# usual. Note that you need to specify all keys (or use the 'PATH_MAP'
+# shorthand) in the allowed_locations option, if you make use of it. Also note
+# that the paths should not overlap each other.
+#
+# The keys are also used to separate the caching of multiple distributions
+# within a single apt-cacher instance if distinct_namespaces is also set.
+#
+#path_map = debian ftp.uni-kl.de/pub/linux/debian ftp2.de.debian.org/debian ; 
+# ubuntu archive.ubuntu.com/ubuntu ; 
+# security security.debian.org/debian-security ftp2.de.debian.org/debian-security
+#
+# There are 2 default internal path_map settings for the Debian and Ubuntu
+# changelog servers which will be merged with this option.
+#
+#   debian-changelogs packages.debian.org
+#   ubuntu-changelogs changelogs.ubuntu.com
+#
+# These can be overridden by specifying an alternative mirror for that key, or
+# deleted by just specifying the key with no mirror.
+#
+#path_map = debian-changelogs
+
+# From version 1.7.0 there is support for caching multiple distibutions (eg
+# Debian and Ubuntu) within the same apt-cacher instance. Enable this by setting
+# distinct_namespaces to 1. Distribution package files are cached in separate
+# directories whose names are derived from the relevant path_map key. So
+# generally there will be a path_map key => server(s) setting for each
+# distribution that is cached. Having enabled distinct_namespaces, existing
+# packages can be imported into the correct directory by running (as root)
+#
+#  /usr/share/apt-cacher/apt-cacher-import.pl -u {cache_dir}/packages
+#
+#distinct_namespaces = 0
+
+# If the 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 IP addresses which are allowed to use it and another list of
+# IP addresses which are prohibited.
+#
+# Localhost (127.0.0.1, ::1 and ::7f00:1) are 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" (which was the
+# default before version 1.7.0). The default is now ''.
+#
+# The format is a comma-separated list containing addresses, optionally with
+# masks (like 10.0.0.0/24 or 10.0.0.0/255.255.255.0), or ranges of addresses
+# (two addresses separated by a hyphen with no masks, specifying a valid subnet,
+# like '192.168.0.0-63' or '192.168.0.0 - 192.168.0.63') or a DNS resolvable
+# hostname.  The corresponding IPv6 options allowed_hosts_6 and denied_hosts_6
+# are deprecated (but will still be honoured, if set). IPv6 addresses can now be
+# added directly to allowed_hosts and denied_hosts along with IPv4 addresses.
+
+allowed_hosts = {{ apt_cacher.get('allowed_hosts', '*') }}
+denied_hosts = {{ apt_cacher.get('denied_hosts', '') }}
+
+# Only allow HTTPS/SSL proxy CONNECT to hosts or IPs which match an item in this
+# list.
+#
+#allowed_ssl_locations =
+
+# Only allow HTTPS/SSL proxy CONNECT to ports which match an item in this list.
+# Adding further items to this option can pose a significant security risk.  DO
+# NOT do it unless you understand the full implications.
+#
+#allowed_ssl_ports = 443
+
+# Optional setting to limit access to upstream mirrors based on server names in
+# the URLs. This is matched before any path_map settings are expanded. If
+# 'PATH_MAP' in included in this option, it will be expanded to the keys of the
+# path_map setting. Note these items are strings, not regexps.
+#
+#allowed_locations = ftp.uni-kl.de, ftp.nerim.net, debian.tu-bs.de/debian
+#allowed_locations = ftp.debian.org, PATH_MAP
+#allowed_locations = PATH_MAP
+
+# List of Ubuntu release names used to expand UBUNTU_RELEASE_NAMES in
+# installer_files_regexp (see below). This is required to allow the Ubuntu
+# installer to fetch upgrade information. As the naming scheme is unpredictable,
+# new release names need to be added to this list.
+#
+#ubuntu_release_names = dapper, edgy, feisty, gutsy, hardy, intrepid, jaunty, karmic, lucid, maverick, natty, oneiric, precise
+
+### HOUSEKEEPING ###
+
+# 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 'report' on the end, like this:
+#
+#      http://yourcache.example.com:3142/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
+
+### INTERNALS ###
+
+# Debug mode makes apt-cacher write a lot of extra debug information to the
+# error log (whose location is defined with the 'log_dir' directive).  Leave
+# this off unless you need it, or your error log will get very big. Acceptable
+# values are 0 or an integer up to 7. See man apt-cacher (1) for further
+# details.
+#
+#debug = 0
+
+# You shouldn't need to change anything below here. If you do, ensure you
+# understand the full implications of doing so.

+
+# Permitted APT pdiff files -- this is a perl regular expression which matches
