NAME

       auto-apt-proxy - autodetect common APT proxy setups

USAGE

       auto-apt-proxy

       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
       proxy to the standard output. This package installs 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
       those 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:

           srv-host=_apt_proxy._tcp.example.com,apt-cacher-ng.example.com,3142

       The appropriate nsd/bind zonefile entry would look like this (untested):

           _apt_proxy._tcp.@  IN SRV 0 0 3142 apt-cacher-ng.@

       As an alternative to an SRV record, one can also define a special hostname which needs to
       be resolved via DNS or local /etc/hosts file, called apt-proxy.  For example, if your
       network has a local apt proxy at 9.9.9.9, then add this line to /etc/hosts:

           9.9.9.9    apt-proxy

CACHING

       By default, auto-apt-proxy will cache its results for 60 seconds.

       To disable the cache, set the `AUTO_APT_PROXY_NO_CACHE` environment variable to any non-
       empty string.

EXAMPLES

       $ auto-apt-proxy

       Just prints the detected APT proxy

       $ auto-apt-proxy debootstrap sid /my/chroot

       Creates a new Debian chroot downloading packages from the local proxy.
