Blind Administration

A few weeks ago I've lost the ability to see any output form my MacBook Pro.

It was a second time. For the first time I had lost the embedded led display only.
The DVI output worked fine. Then came the healing power of promise - I have to buy a new one.
But threat without the coverage it's just the bucket of words.
The MBP makes me blind completely and definately. No video output. No remote access.
No working ssh daemon, no firewall access, no future.

I thought the target mode would be the cure.
I have PowerBook Pismo with Tiger onboard. Unfortunately, the data on MBP was encrypted with
a FileVault from Snow Leopard. Either try of target mode connection, or try of manual mount failed.

Collecting of the recipe components took me many hours, often filled with an exasperation.
Hidden typos. Invisible prompts. Lurking daemons.

The recipe.
It's here to remember. It's here to save other souls.

Power On.
Listen to chime and wait a few moments, then log in yourself:
username TAB

Open Applications
and invoke your favourite text terminal by typing its name, followed by CMD+O
i t e r m ⌘+O

Confirm you're in:
$ say ok
$ sudo su
> put your password <
Confirm your personality.
$ whoami | say
Let the dogs out. Select a race, choose wisely.
$ launchctl load -w /System/Library/LaunchDaemons/telnet.plist # enable configuration and
$ launchctl load -w /System/Library/LaunchDaemons/ssh.plist    # set Disable key to false
$ launchctl start com.apple.telnetd
$ launchctl start com.openssh.sshd
Check the locks.
$ defaults read /Library/Preferences/com.apple.alf globalstate | say
Firewall states
  • 0 - de-activated
  • 1 - on for specific services
  • 2 - on for essential services
Open the gates.
Pretty enough for older systems (Tiger), where no reboot required:
$ ipfw flush
> 'y' to flush <
$ ipfw list | say # 'any to any' means success
Permanent solution:
$ defaults write /Library/Preferences/com.apple.alf globalstate -int 0
$ reboot
Connect and enjoy it.
