$ wget https:\/\/aur.archlinux.org\/packages\/uc\/ucspi-tcp\/ucspi-tcp.tar.gz<\/p>\n

$ tar -xvzf ucspi-tcp.tar.gz<\/p>\n

$ cd ucspi-tcp<\/p>\n

$ nano PKGBUILD<\/p>\n

——————–<\/p>\n

arch=('arm')<\/p>\n

——————–<\/p>\n

change line 36 to:<\/p>\n

install -m 755 -D $bin $pkgdir\/usr\/bin\/$bin<\/p>\n

(refer to the comments at https:\/\/aur.archlinux.org\/packages.php?ID=8330 <\/a>)<\/p>\n

 <\/p>\n

$ sudo pacman -U ucspi-tcp-0.88-3-arm.pkg.tar.xz<\/p>\n

 <\/p>\n

 <\/p>\n

Now for the real thing:<\/p>\n

 <\/p>\n

$ wget https:\/\/aur.archlinux.org\/packages\/dj\/djbdns-ipv4\/djbdns-ipv4.tar.gz<\/p>\n

$ tar -xvzf djbdns-ipv4.tar.gz<\/p>\n

$ cd djbdns-ipv4\/<\/p>\n

I built mine on my PogoPlug, so I needed to edit  PKGBUILD and edited: arch=('arm')<\/p>\n

$ makepkg<\/p>\n

$ sudo pacman -U djbdns-ipv4-1.05-2-arm.pkg.tar.xz<\/p>\n

 <\/p>\n

============<\/p>\n

>>> Configure and run tinydns:
\n\t    tinydns-conf _tinydns _dnslog \/service\/tinydns [IP]
\n\t    ln -s \/service\/tinydns \/etc\/<\/p>\n

>>> Configure and run dnscache as a recursive cache:
\n\t    dnscache-conf _dnscache _dnslog \/service\/dnscache [IP]
\n\t    ln -s \/service\/dnscache \/etc\/<\/p>\n

>>> To change from recursive to forward-only:
\n\t    echo 1 > \/service\/dnscache\/env\/FORWARDONLY
\n\t    echo IP_address_of_a_recursive_DNS server > \/service\/dnscache\/root\/servers\/@
\n\t    echo IP_address_of_another_recursive_DNS server >> \/service\/dnscache\/root\/servers\/@<\/p>\n

>>> To add a local authoritative server to a recursive or forward-only setup:
\n\t    echo IP_address_of_a_local_authoritative_server > \/service\/dnscache\/root\/servers\/name.of.toplevel.domain<\/p>\n

If [IP] is omitted dnscache will run on localhost.
\n\tMore help can be found at http:\/\/cr.yp.to\/djbdns.html<\/p>\n

Read \/usr\/share\/djbdns\/README for more information about this package.<\/p>\n

=================<\/p>\n

 <\/p>\n

Let's set up the dns cache on the box's IP (10.0.0.240 in the example)<\/p>\n

 <\/p>\n

 <\/p>\n

# dnscache-conf _dnscache _dnslog \/etc\/dnscache 10.0.0.240<\/p>\n

Start it<\/p>\n

# ln -s \/etc\/dnscache \/service\/<\/p>\n

ps ax should show something like:<\/p>\n

9438 ?        S      0:00 supervise dnscache
\n\t 9439 ?        S      0:00 supervise log
\n\t 9440 ?        S      0:00 multilog t .\/main
\n\t 9441 ?        S      0:00 \/usr\/bin\/dnscache
\n\t <\/p>\n

Tell DNSCACHE to accept queries from your intranet:<\/p>\n

touch \/etc\/dnscache\/root\/ip\/10<\/pre>\n
 <\/p>\n
Let's tail its log:<\/p>\n
# tail -f \/service\/dnscache\/log\/main\/current<\/p>\n
And test it, opening another terminal<\/p>\n
# dnsip www.cnn.com<\/p>\n
As of this writing you should see:<\/p>\n
157.166.255.18 157.166.255.19 157.166.226.26 157.166.226.25<\/p>\n
and a bunch of log output<\/p>\n
