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 downloaded 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 configuration files find there.

       -h     Short option summary

       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  configuration  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 that settings 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.
