I'm thinking about setting up a pair of Rasp-Pi-4 as DNS servers with |
| 2 |
4GB of ram. Is that enough ram for a DNS server? |

If 4GB is not enough, there are some boards with 8GB |
| 10 |
of ram. |
| 11 |
|
| 12 |
|

What about running postfix on a third board? |

All feedback is encouraged. It will not be a high volume postfix email |
| 19 |
system. As far as the DNS servers, it seems I vaguely remember some |
| 20 |
software or filters to prevent hack attacks, that just overwhelm DNS |
| 21 |
servers; or something like that. It just lowers the data flow rate. |
| 22 |
|
| 23 |
It seems this is popular, and which version of USB 3.? |
| 24 |
to use on a stick, as now usb sticks can have large capacities now (T+). |
| 25 |
|
| 26 |
Surely I'll back up the mail (spool & such) to a secondary hard drive on |
| 27 |
another system. |
| 28 |
|
| 29 |
It this all goes well, surely I put a web server on a fourth board. |

Granted those links are not centric to embedded gentoo, but they do |
| 35 |
cover a lot of what is needed. |
| 36 |
|
| 37 |
Further suggestions are most welcome. This is a fun to do project, |
| 38 |
useful as it would basically be easy to duplicate, so I can travel |
| 39 |
anywhere, get a few static IPs and deploy a small business, |
| 40 |
self-sufficient, network. |
| 41 |
|
| 42 |
So the Rpi4 boards will all need their own unique, static Ip. But, |
| 43 |
another questions is while they are running as 4 distinct gentoo |
| 44 |
servers, could they also double as a quad-gentoo cluster? |

Security pointers are most welcome too. |
| 50 |
The eventual idea is to have a fixed home network, but |
| 51 |
be able to travel around in my pickup/cabovercamper |
| 52 |
and have what I need right there, or provide it to friends as a ready to |
| 53 |
go small network. Embedded Gentoo, |
| 54 |
low-power hardware and 100% (gentoo) source driven). |
| 55 |

The S20 (520G ram) phone would server as the router. |
| 57 |
(2) 5G cell phones running on (2) different 5G service |
| 58 |
vendor, could make the services and cluster multi-homed? |
| 59 |
|
| 60 |
Would all of this work with just IP6 and a fancy cell phone, running |
| 61 |
gentoo? We shall see. |
