I installed a Proxmox server on the local home network which is running on 192.168.2.100 and I can successfully SSH to it from my MacBook (Sequoia 15.1.1 24B91) using IP address. However, I cannot SSH using hostname. I have updated my /private/etc/hosts file, however I can’t seem to SSH via hostname.
I can SSH using IP:
❯ ssh [email protected]
[email protected]'s password:
Port is open:
❯ nc -zv 192.168.2.100 22
Connection to 192.168.2.100 port 22 [tcp/ssh] succeeded!
Hosts file:
❯ cat /private/etc/hosts

What else can it be?
