This will increase the swap file to 500MB before downloading the lists.
Most of the issue comes from the mahakala list, which is so large. If
no swap file is found, one is created.
Some people use a hostname other than raspberrypi, so their hostname
did not resolve to 127.0.0.1. I replaced that hardcoded value with a
variable so that does not happen.
I also added a few comments and minor formatting adjustments,.
Pushing files so they are available when the new article gets posted.
If the Pi's loopback is set in the hosts file, clients using it as a
DNS server will try to connect to their own loopback, which does not
have a Web server. So the real IP of the Pi is used. It is
recommended to use a static IP since this will be acting as a server.
Made one small change from some hard coded values to a variable.
Originally, I had this set to /run/shm (in RAM) but ran into errors
when the list reached 900,000 entries.
Then I moved it to /tmp.
Finally, I decided to just put the files in the pihole dir so they are
available after reboots. This will help with only downloading the
lists when absolutely needed--respecting the bandwidth of the people
serving the lists.
It is also possible to add addn-hosts=/path/to/hosts.conf within the
dnsmasq.conf file if you don't want to use hosts. For simplicity and
speed, I just use the regular hosts file.
Still need to get lighted to use IPv6. I am doing this because some
ads can get through using IPv6 if the IPv4 version is blocked. Also,
it seems to work fine as far as performance even though it doubles the
file size...
Also added a few comments for better documentation.
