NAME¶auto-apt-proxy - autodetect common APT proxy setups
auto-apt-proxy [COMMAND [ARGS ...]]
DESCRIPTION¶auto-apt-proxy is an APT proxy autodetector, and detects common setups by checking localhost, your gateway and other "interesting" machines on your network for well-known APT proxies such as apt-cacher-ng and others.
When called with no arguments, auto-apt-proxy simply prints the address of a detected process to the standard output. This package install an APT configuration file that makes APT use auto-apt-proxy to detect a proxy on every invocation of APT.
When called with arguments, they are assumed to be a command. Such command will be executed with the common environment variables used for specifying HTTP proxies (http_proxy, HTTP_PROXY) set to the detected proxy. This way the executed command will be able to transparently use any detected APT proxy. Note that for this to work, any programs invoked by the given command must have their own support for detecting HTTP proxies from environment variables, and for using them.
CONFIGURATION¶When your apt proxy is installed on localhost or your default gateway, it should Just Work. If you install it somewhere else, you can create an explicit SRV record to tell auto-apt-proxy about it.
Suppose your corporate domain is "example.com", and apt-cacher-ng is installed on "apt-cacher-ng.example.com", and auto-apt-proxy is installed on "alices-laptop.example.com".
The appropriate SRV record in dnsmasq.conf would look like this:
The appropriate nsd/bind zonefile entry would look like this (untested):
_apt_proxy._tcp.@ IN SRV 0 0 3142 apt-cacher-ng.@
Just prints the detected APT proxy
$ auto-apt-proxy debootstrap sid /my/chroot
Creates a new Debian chroot downloading packages from the local proxy.
