-#################################################################​ +
-# 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. +
-allowed_hosts_6=fec0::/​16 +
-denied_hosts_6= +
- +
-# 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 +
-# package-type files (files that are uniquely identified by their filename).  +

- +
-# 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).  +
