APPROX-GC(8)						      System Manager's Manual						      APPROX-GC(8)

NAME

       approx-gc - garbage-collect the cache of Debian archive files

SYNOPSIS

       approx-gc [OPTION]...

DESCRIPTION

       approx-gc  scans  the  cache created by approx(8) and finds files that are corrupted or no longer needed.  With no options specified, these
       files are listed on standard output and removed from the cache.

       A corrupted file is one whose size or checksum does not match the value specified in the Packages or Sources file.

       An unneeded file is one that is not referenced from any distribution's Packages or Sources file.

       approx-gc may take several minutes to finish.

OPTIONS

       -c file, --config file
	      Specify an additional configuration file.  May be used multiple times.

       -f, --fast
	      Don't perform checksum validation.

       -k, --keep, -s, --simulate
	      Don't remove files from the cache.

       -q, --quiet
	      Don't print file names.

       -v, --verbose
	      Print the reason for removal of each file.

EXAMPLES

       To remove all unneeded or corrupted files from the cache:

	      approx-gc --quiet

       This is run as a weekly cron(8) job.

       To list the files that would be removed from the cache, without actually doing so:

	      approx-gc --keep

FILES

       /etc/approx/approx.conf
	      Configuration file for approx and related programs.

       /var/cache/approx
	      Default cache directory for archive files.

NAME

       approx.conf - configuration file for approx proxy server

SYNOPSIS

       /etc/approx/approx.conf

DESCRIPTION

       Each  non-blank line of the configuration file should contain a name/value pair, separated by white space.  Comments start with a "#" char-
       acter and continue to the end of the line.

       Names that begin with the "$" character are reserved for use as configuration parameters.  The following parameters are currently defined:

       $cache Specifies the location of the approx cache directory (default: /var/cache/approx).  It and all its subdirectories must be  owned  by
              the approx server (see also the $user and $group parameters, below.)

       $interval
              Specifies the time in minutes after which a cached file will be considered too old to deliver without first checking with the remote
              repository for a newer version (default: 60)

       $max_rate
              Specifies the maximum download rate from remote repositories, in bytes per second (default: unlimited).  The value may  be  suffixed
              with "K", "M", or "G" to indicate kilobytes, megabytes, or gigabytes per second, respectively.

       $max_redirects
              Specifies the maximum number of HTTP redirections that will be followed when downloading a remote file (default: 5)

       $user, $group
              Specifies the user and group that owns the files in the approx cache (default: approx)

       $syslog
              Specifies the syslog(3) facility to use when logging (default: daemon)

       $pdiffs
              Specifies whether to support IndexFile diffs (default: true)

       $offline
              Specifies  whether  to deliver (possibly out-of-date) cached files when they cannot be downloaded from remote repositories (default:
              false)

       $max_wait
              Specifies how many seconds an approx(8) process will wait for a concurrent download of a file  to  complete,  before  attempting  to
              download the file itself (default: 10)

       $verbose
              Specifies whether informational messages should be printed in the log (default: false)

       $debug Specifies whether debugging messages should be printed in the log (default: false)

       The other name/value pairs  are used to map distribution names to remote repositories.  For example,

              debian          http://ftp.debian.org/debian
              security        http://security.debian.org

TCP PORT NUMBER

       The  port  on  which approx(8) listens is not specified in this file, but in /etc/inetd.conf.  The default value is 9999, for compatibility
       with apt-proxy(8), but it may be changed by running the command

              dpkg-reconfigure approx
