🖥️ Use the TrueNAS SCALE Console (via Proxmox)

In Proxmox Web UI → TrueNAS VM → Console:

Use console select 8 for Open Linux Shell

Then run:

ip a

Look for an interface named ens18, enp0s3, vtnet0, etc.

If no IP is assigned, run:

systemctl restart networking

Then request DHCP manually:

dhclient ens18

Replace ens18 with your NIC if it’s different.

Drawbacks!

Changes the IP address from the original. Mapped netwrok drives will have to be updated.

NOTES/EXTRA READING:

https://linux.die.net/man/8/dhclient

The DHCP protocol allows a host to contact a central server which maintains a list of IP addresses which may be assigned on one or more subnets.

https://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol

When connected to the network, and periodically thereafter, a client requests a set of parameters from the server using DHCP.
