This is intended to be a reference for setting up a VM or Server for AllStatLink.

Server Overview

Basic Requirements

AllStarLink has standardized on Ubuntu 16.04 LTS for it's servers.

The minimum configuration of any server will be 2 cores of 2 GHz or faster, 4 GiB of ram and 40 GiB of Disk.

All new servers shall support IPv6, or have it available from the hosting provider.

Reverse IP's shall be delegated via a CNAME to $NAME.PTR.allstarlink.org, where $NAME is the name of the server.

All servers shall be partitioned to use / as the only partition unless a specific configuration is required.

Install guide

When provisioning a new server

  • check the VM is setup (cpu/mem/disk) as it should be, if not contact the provider.

  cat /proc/cpuinfo |grep processor
  processor       : 0
  processor       : 1
  processor       : 2
  processor       : 3

  • on the server install python (apt-get install python). This is needed for the ansibile provisioning
  • setup the server in the infrastructure configs and push the users and keys to it.

Mandatory Software

All servers require this software

apt-get install ntp python vim screen ipsec-tools strongswan fail2ban

Mandatory Configs

  • The network should be configured to use /etc/network/interfaces
  • There is typically only one network interface, and it will be named dynamically. We must setup this using udev to be persistant

   root@server# ifconfig |grep HWaddr
   eth0      Link encap:Ethernet  HWaddr 52:54:00:73:86:06  

Now take this HWaddr and put it in the config file echo 'SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="52:54:00:73:86:06", ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="eth0"' >/etc/udev/rules.d/70-persistent-net.rules
