Can't bind in macOS Ventura: permission denied

[jeisoncp]

I tried to tunneling the VNC port (5900) over SSH, as the documentation says:

exit
ssh -L 5900:localhost:5900 -i <ec2-key-pair> ec2-user@<ip-address>

But the remote console returns:

bind [127.0.0.1]:5900: Permission denied
Last login: Mon Jan  2 21:07:03 2023 from [...]

I do not believe this to be a Ventura issue on the client side.

1. Did the binding work from your current client to an EC2 Mac instance running Monterey?
2. Is this client managed by your employer?

Hi Jon!

1. I didn't tested from Monterey yet. I will try in my next use.
2. Yes, it's my employer's machine.

Thanks!

I founded what the problem was: I had TightVNC Server installed and using the 5900. So the problem was occurring on my side.

I removed it (because a use only a viewer), and now I can bind normally.
