# 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



If `avahi-browse` is installed, then **auto-apt-proxy** will try to find any

proxies announced via mDNS. If, for some reason, you would prefer the name of

the announced proxy to be resolved via NSS rather than the somewhat arbitrary

order provided by Avahi, you can set `AUTO_APT_PROXY_AVAHI_NAME` environment

variable to any non-empty string. `AUTO_APT_PROXY_AVAHI_NAME` does not change

which proxy is used if multiple mDNS provided proxies are available.



# 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.
