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


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


       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.


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

       -c confdir
              Scan the specified configuration directory and interpret configuration  files  find

       -h     Short option summary

              The  options  from the configuration can be passed on the command line as key=value


       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

       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).


       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.

       the  doc/pdf  directory  of  the software source package or installed in the documentation
