This unique feature allows the following to be accessed securely over SSH:
Your VM's serial port
Common use case is to run a getty process on it, for out-of-band management, without a need for VNC.
The following devices are made available:
- /dev/ttyS0 (Linux)
- /dev/ttyu0 (FreeBSD)
- /dev/tty00 (OpenBSD)
Tunnel VNC over SSH
Encrypt all VNC traffic for more secure out-of-band management that does not require the serial port.
Instructions for doing so are available by selecting the 't' option once logged into the console server (see below).
- Ability to boot, shutdown gracefully (via ACPI), and forcefully halt any VM
Example serial port session
We give you an account on our console server and you give us your SSH public key.
The fun begins:
$ ssh firstname.lastname@example.orgYou will then be presented with:
Welcome to the ARP Networks VM management console Select from the following functions l list virtual machines b boot s shutdown (graceful) * S shutdown (hard) c connect to serial console t tunnel VNC over SSH (instructions) q quit * graceful shutdown requires that your VM responds to an ACPI shutdown signal > _Pressing 'c' will connect you to the VM's serial port:
