-#################################################################​ 
-# This is the config file for apt-cacher. On most Debian systems 
-# you can safely leave the defaults alone. 
-#################################################################​ 
- 
-# cache_dir is used to set the location of the local cache. This can 
-# become quite large, so make sure it is somewhere with plenty of space. 
-cache_dir=/​mnt/​no_data/​apt-cacher 
- 
-# The email address of the administrator is displayed in the info page 
-# and traffic reports. 
-admin_email=root@localhost 
- 
-# For the daemon startup settings please edit the file /​etc/​default/​apt-cacher. 
- 
-# Daemon port setting, only useful in stand-alone mode. You need to run the 
-# daemon as root to use privileged ports (<1024). 
-daemon_port=3142 
- 
-# optional settings, user and group to run the daemon as. Make sure they have 
-# sufficient permissions on the cache and log directories. Comment the settings 
-# to run apt-cacher as the native user. 
-group=www-data 
-user=www-data 
- 
-# optional setting, binds the listening daemon to specified IP(s). Use IP 
-# ranges for more advanced configuration,​ see below. 
-daemon_addr=repository-2.dev.jj.com 
- 
-# 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. 
-# Note that IPv4-mapped IPv6 addresses (::​ffff:​w.x.y.z) are truncated to 
-# w.x.y.z and are handled as IPv4.

-# This thing can be done by Apache but is much simpler here - limit access to 
-# Debian mirrors based on server names in the URLs 
-allowed_locations=* 
- 
-# 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 = 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 
- 
-# 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. 
-# 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

-# Permitted package files - this is a perl regular expression which matches all

- 
-# 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 
-# need to be checked for freshness). ​ 
-#The default is:
