How is "uniqid" for a VIP entry generated

xciter327

I am writing a jinja based template engine for initial pfsense configuration. I've done most of the other configuration section and now I want to create the <virtualip> via a template. Could somebody explain how is the "uniqid" entry populated?

I've taken a look in https://github.com/pfsense/pfsense/blob/master/src/usr/local/www/firewall_virtual_ip_edit.php

However I don't see it being set or generated in that file.

What is see is that it's always a alphanumerical field with lowercase letters and a length of 13 characters.

Could anybody confirm my assumptions?

Here is code example:

  <vip>
    <mode>carp</mode>
    <interface>wan</interface>
    <vhid>2</vhid>
    <advskew>0</advskew>
    <advbase>10</advbase>
    <password>{{ carp_password }}</password>
    <uniqid>5aa10f2a5b569</uniqid>
    <descr><![CDATA[WAN IPv6 CARP IP]]></descr>
    <type>single</type>
    <subnet_bits>{{ wan_ipv6_network }}</subnet_bits>
    <subnet>{{ wan_carp_ip_ipv6 }}</subnet>
  </vip>

Hi jimp, thaks for the quick reply. So my suspicion is confirmed. 13 characters, alphanumeric.

Hello, I came across the same topic, it was very useful for me.

This is how I decided to implement it in ansible.

- name: "Generate a virtual ip address uniq id"
  ansible.builtin.debug:
    var: query('community.general.random_string', upper=false, special=false, min_numeric=10, min_lower=3, length=13)
  # Example result: ['202121w730p1q']
