12 Apt-Cacher NG is a caching proxy for software packages which are down‐
13 loaded by Unix/Linux system distribution mechanisms from mirror servers
14 accessible via HTTP.
15
17 The command-line options supported by apt-cacher-ng are:
18
19 -c confdir
20 Scan the specified configuration directory and interpret config‐
21 uration files find there.
22
23 -h Short option summary
24
25 varname=varopt
26 The options from the configuration can be passed on the command
27 line as key=value pairs.
28
30 Apt-Cacher NG is configured by a multi-config directory, i.e. the con‐
31 figuration is split into many configuration files having names with
32 suffix .conf and stored in a single directory. Variables can override
33 previously configured settings from other files, sometimes that set‐
34 tings are merged (depending on the variable).
35
36 The configuration directory is typically /etc/apt-cacher-ng but it can
37 be adjusted with the -C option (see systemd service file for details or
38 wherever the init system starts the daemon).
39
40 On Debian systems, there are at least three files installed by default:
41 acng.conf (containing documented examples), security.conf (containing
42 sensible data and only readable for special users) and zz_debconf.conf
43 (containing popular settings which are set by the Debian Configuration
44 mechanism).
45
47 Only few signals are handled in non-default ways.
48
49 SIGUSR1 closes and reopens log files.
50
51 SIGTERM and SIGINT close log files and stop the daemon.
52
54 For more information on Apt-Cacher NG, read the User Manual which can
55 be found either in the doc/pdf directory of the software source package
56 or installed in the documentation directory of apt-cacher-ng by your
57 distribution.
