During the install there are two hidden console screens that can be used for debugging. The screen you normally see during installation can be reached by pressing the ALT-F1 key combination.

If you press ALT-F2 you will see detail messages from the Linux commands run during the install.

If you press ALT-F3 you will be at a Linux command prompt.

During the first part of the install, until the full IPCop file system is built, the commands available at this prompt are extremely limited. Type

# help

for a list of shell built-in commands, and

# ls /bin

for a list of individual commands.
