       apt-proxy.conf - configuration file for apt-proxy


       apt-proxy.conf is the configuration file for apt-proxy.  When apt-proxy
       starts up, it will read /etc/apt-proxy/apt-proxy.conf.

       /etc/apt-proxy/apt-proxy-v2.conf will be read instead if it  exists  to
       make upgrading from v1 easier.

       The  configuration file is divided up into several sections, where each
       [resource] section defines a separate  resource.  The  DEFAULT  section
       applies to all resources.

       The supplied apt-proxy.conf will work out of the box, but it is best to
       change the backends you use to a mirror closer to you.  There are  some
       in  the default file, and it may be enough just to reorder the lines in
       the file.


       This section holds options global to the whole apt-proxy:

              IP address on which apt-proxy will listen for requests. Multiple
              addresses have a empty space between it.

       port   TCP port on which apt-proxy will listen for requests.

              If  different  from  off,  means that Packages and other control
              files will not be refreshed until they are at least this age.

              Maximum I/O timeout in seconds for backend  transfers.  Default:
              30 seconds.  If no response is received from a backend server in
              this time, apt-proxy will try the next server in the list.  Y

              Cache directory.  Default: /var/cache/apt-proxy

              If different from off, indicates the time  between  housekeeping
              attempts:  delete  files that have not been accessed in max_age,
              scan cache directories and update internal tables, ...

              If different from off, indicates the maximum age of files before
              deletion from the cache.

              If  different from off, indicates the maximum number of versions
              of a  .deb  to  keep.   This  is  the  number  of  versions  per
              distribution,  for example setting max_versions to 2 will ensure
              that a maximum of 6 packages would be kept: the  last  2  stable
              versions,  the  last  2 testing versions and the last 2 unstable
              versions. NOTE: If your system clock  is  very  inaccurate  this
              will not work properly and should be disabled.

              Specify  on  to  use  passive  FTP,  which  works  from behind a
              firewall, but may not be supported on all servers.  Specify  off
              to use active FTP instead.  Default: on

              Specify  [username:password@]hostname:port  to  use  an upstream
              proxy.  Username and password are optional.

              By default apt-proxy will add HTTP backends dynamically  if  not
              already  defined. Specify off to restrict the available backends
              to those listed in the configuration file.  Default: on

              apt-proxy can use HTTP pipelining to fetch several files at once
              (up  to  10), but this can generate multiple connections to each
              backend server.  Pipelining is disabled by default until this is
              fixed.   Set  to  0  to  enable  experimental  http  pipelining.
              Default: 1

       bandwidth_limit = amount
              When downloading from a backend server, limit the download speed
              to  amount bytes per second. Note this applies to http and rsync
              backends only. Default: no limit


       All other sections in the configuration file  will  be  interpreted  as
       resource  names.   The  options  in  the section apply to this resource

              Overrides the global timeout

       backends = <protocol>://<server>/<directory> [...]
              A list one or more URLs referring to servers which  hold  debian
              protocol: internet protocol to use: http, ftp or rsync
              server: hostname of the backend server to contact
              directory: directory name to prepend requests to for this server

              Override the global setting of passive_ftp

              Set  a  bandwidth  limit  for  downloads  for   this   resource,
              overriding the global bandwidth_limit

              Specify  [username:password@]hostname:port  to  use  an upstream
              proxy, overriding the global http_proxy.

              Override the global min_refresh_delay for this backend. Set this
              to the interval at which this archive is usually refreshed.


       To  access  a  resource  that’s  listed  under a specific section name,
       simply append the section name (without the brackets)  to  the  end  of
       your deb source line in /etc/apt/sources.list

       Debian main

       This  example  shows  how  to  give  clients  access to the main Debian
       backends =

       Using this configuration, the client would  use  a  sources.list  entry

           deb http://server:9999/debian woody main

       And             so             the             file             request
       ‘/debian/woody/main/binary-i386/x11/foo_1-1.deb’  would  turn  into   a
       backend request of first


       and if that failed,


       and apt-proxy will place the downloaded package in

       The website tells you to use this sources.list line:

           deb sarge-backports main

       You   can   add  this  to  apt-proxy  by  creating  a  new  section  in
       apt-proxy.conf.  In the new section, add a backends entry for the URL:

           backends =

       On the clients, replace the URL with  one  pointing  to  the  apt-proxy
       resource  name,  in the form http://hostname:port/backend. If your apt-
       proxy hostname is proxy and it is  running  on  port  9999,  you  would

          deb http://proxy:9999/backports sarge-backports main

       For many more examples, see the supplied /etc/apt-proxy/apt-proxy.conf.
