Host Machine

Create Instance

Interserver Web Interface

  1. go to interserver
  2. create an instance
    1. Single Slice ($6/mo at this time)
    2. Debian 9 (Deb 9 has Mailman 2, Deb 10 has Mailman 3)
    3. KVM
  3. set reverse DNS to diffie.deadmandao.com
  4. Note the IP address

Update to Latest

Log in root@ip.address using password you provided 

apt-get update
apt-get -y upgrade
apt-get -y dist-upgrade # if needed
reboot

Add User Account

Log in root@ip.address 

apt-get -y install sudo
adduser bob
usermod -G sudo bob
exit

Host MX Settings

Log in to bob@ip.address

Set SPF

sudo apt-get install net-tools
sudo ifconfig

That'll give you the ip4 and ip6 addresses, which go into the DNS text record:

  • v=spf1 ip4:66.23.226.216 ip6:fe80::216:3eff:fe24:10e1 -all

Set Other DNS

  • A Record, diffie, 66.23.226.216
  • A Record, @, 66.23.226.216
  • CNAME Record, www, diffie.deadmandao.com
  • CNAME Record, mail, diffie.deadmandao.com
  • TXT Record, diffe, v=spf1 ip4:66.23.226.216 ip6:fe80::216:3eff:fe24:10e1 -all
  • MX Record, deadmandao.com, mail.deadmandao.com, 10

Set Hostname

sudo apt-get install emacs-nox
sudo emacs -nw /etc/hostname
> diffie
sudo emacs -nw /etc/hosts
> 66.23.226.216	diffie.deadmandao.com diffie
sudo reboot

Log in to bob@diffie.deadmandao.com

hostname --all-fqdn
