<code> ################################################################# # 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
