A2SERVER
If you had A2SERVER running, and you typed either apt-get update or rpi-update, you may have received Linux kernel version 3.12 through 3.15. These, unfortunately, include a defective AppleTalk kernel module which will kernel panic (crash) your system on startup when A2SERVER tries to activate AppleTalk networking.
If you have a screen or console cable attached, you will see some debugging information that concludes with "Kernel panic." If you don't have a screen attached, there will be no visible signs other than that you simply can't connect from another computer on your network.
To prevent this from happening, type a2server-setup before updating the software on your computer. If it's too late, and you need to recover from this situation, you could start over. Or, if you want to keep your current installation, you have a few options, depending on your setup:
A2SERVER virtual machine, or on other non-Raspberry Pi Linux computer
- Start up the virtual or real machine.
- On the GRUB startup screen, choose the Recovery kernel.
- At the Linux prompt, type
a2server-setup
A2SERVER on Raspberry Pi with screen/keyboard/mouse attached
- Press the shift key rapidly and repeatedly while your Pi starts up. If you have an HDMI monitor, you can stop when you see the installer screen. If you have a composite monitor, stop after about a minute, and then press 3 (PAL, e.g. Europe) or 4 (NTSC, e.g. North America and Japan), and you should see the installer screen.
- Press E for Edit, then click the cmdline.txt tab.
- At the end of the line, append
single (preceded by a space).
- Press OK to save, then ESC to reboot.
- Log in with username "pi" and password "apple2".
- At the Linux prompt, type
a2server-setup
A2SERVER on Raspberry Pi without screen/keyboard mouse, and a Mac
- Remove the SD card from your Pi and insert it in your Mac.
- Look for a volume named BOOT to appear.
- Within it, open cmdline.txt in a text editor (the default is TextEdit).
- At the end of the line, append
single (preceded by a space), then save it.
- Eject the SD card and put it back in your Pi, then start up your Pi.
- Log in to your Pi and type
a2server-setup
A2SERVER on Raspberry Pi without screen/keyboard mouse, and a Linux computer
- Remove the SD card from your Pi.
- On your Linux computer, type:
wget ivanx.com/a2server/fix; source fix
- Follow the on-screen instructions.
- If after using the fix tool, you still can't connect from your Apple II, log in to your Pi, and type
a2server-setup
- (Alternative approach: Follow the Mac method above, though the volume may not appear as BOOT.)
A2SERVER on Raspberry Pi without screen/keyboard/mouse, and a Windows computer
- Remove the SD card from your Pi.
- Install the A2SERVER virtual machine on your Windows computer.
- Start the virtual machine, and log in with user name "user1" and password "apple2".
- In the virtual machine window, type:
wget ivanx.com/a2server/fix; source fix
- Follow the on-screen instructions.
- Type
system-shutdown in the virtual machine window.
- Quit VirtualBox.
- If after using the fix tool, you still can't connect from your Apple II, log in to your Pi, and type
a2server-setup
