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 direc‐ tory. 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 (con‐ taining 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.
