NAME
       apt-cacher-ng - caching proxy for software package downloads

SYNOPSIS
       apt-cacher-ng [-c confdir] [-h] [optname=optvalue ...]

DESCRIPTION
       Apt-Cacher  NG is a caching proxy for software packages which are down-
       loaded by Unix/Linux system distribution	mechanisms from	mirror servers
       accessible via HTTP.

OPTIONS
       The command-line	options	supported by apt-cacher-ng are:

       -c confdir
	      Scan the specified configuration directory and interpret config-
	      uration files found there.

       -h     Short option summary

       -i     Ignore some non-critical configuration errors on startup.	 Regu-
	      lar operation with this switch is	not recommended.

       -v     Enable additional	verbosity in log output.

       -e     Invoke  expiration  task	immediately after startup. This	option
	      exists for legacy	compatibility and can be dangerous to use  due
	      to filesystem permission issues (i.e. danger to cause them). Us-
	      ing acngtool to control such operations instead is advisable.

       varname=varopt
	      The options from the configuration can be	passed on the  command
	      line as key=value	pairs.

CONFIGURATION
       Apt-Cacher  NG is configured by a multi-config directory, i.e. the con-
       figuration is split into	many configuration  files  having  names  with
       suffix  .conf  and stored in a single directory.	Variables can override
       previously configured settings from other files,	sometimes  those  set-
       tings are merged	(depending on the variable).

       The  configuration directory is typically /etc/apt-cacher-ng but	it can
       be adjusted with	the -c option (see systemd service file	for details or
       wherever	the init system	starts the daemon).

       On Debian systems, there	are at least three files installed by default:
       acng.conf (containing documented	examples),  security.conf  (containing
       sensible	 data and only readable	for special users) and zz_debconf.conf
       (containing popular settings which are set by the Debian	 Configuration
       mechanism).

SIGNALS
       Only few	signals	are handled in non-default ways.

       SIGUSR1 closes and reopens log files.

       SIGTERM and SIGINT close	log files and stop the daemon.

MORE INFORMATION
       For  more  information on Apt-Cacher NG,	read the User Manual which can
       be found	either in the doc/pdf directory	of the software	source package
       or  installed  in  the documentation directory of apt-cacher-ng by your
       distribution.
