This section provides the steps to reconfigure FQDN and IP addresses in the system, IPv4, IPv6 only, and dual stack are supported.
Prerequisites
DNS servers should be able to resolve the FQDN to the IP addresses that will be set to the Airgap Appliance.
Procedure
- Login the TCA Airgap Appliance via SSH admin account then switch to root with
su
to use agctl
command.
- Edit
/usr/local/airgap/scripts/vars/user-inputs.yml
using the following command:
vi /usr/local/airgap/scripts/vars/user-inputs.yml
- Update the following settings. For more information on the parameters, see Agctl CLI Command Reference:
server_fqdn: <full qualified domain name of the airgap appliance>
ip_family: <could be "ipv4", "ipv6" or "ipv6,ipv4"
dhcp: <True or False>
static_ip: <ip addresses seperated by comma>
default_gw: <gateway ips seperated by comma>
dns_servers: <dns server IPs seperated by comma>
Examples:
IPv4 Static
server_fqdn: airgap.example.com
ip_family: ipv4dhcp: False
static_ip: 192.168.100.100/24
default_gw: 192.168.100.1
dns_servers: 192.168.100.253
IPv6 Static
server_fqdn: airgap.example.com
ip_family: ipv6dhcp: False
static_ip: fc00:192:168:100::100/64
default_gw: fc00:192:168:100::1
dns_servers: fc00:192:168:100::253
Dual Stack
server_fqdn: airgap.example.com
ip_family: ipv6,ipv4
dhcp: False
static_ip: fc00:192:168:100::100/64,
default_gw: fc00:192:168:100::1,192.168.100.1
dns_servers: fc00:192:168:100::253,192.168.100.253
IPv4 DHCP
server_fqdn: airgap.example.com
ip_family: ipv4
dhcp: True
- Save and run
agctl deploy
command to apply the settings.
