[Buildroot] hang generating DSA keys

[Frank Hoeflich]

The entropy mechanism depends on keyboard input - I'd expect it to be waiting for I/O.? If you type some characters it will use them to generate the keys and be on its way.

Yes, if the programs are using /dev/random instead of /dev/urandom. Is
this openssh or dropbear? Dropbear uses /dev/urandom by default, but I
don't know what openssh does.

sorry for the delay in replying. This was openssh. I ended up disabling it for
now since I can do everything I need on the console.

This is really odd. I'm using the same buildroot code as I have been for
weeks, but after flashing my latest code to my Atmel ngw100, it hang in the
first boot at this step:

Generating DSA Key...
THIS CAN TAKE A MINUTE OR TWO DEPENDING ON YOUR PROCESSOR!

Generating public/private dsa key pair.

I let it sit overnight and it never finished. I remember seeing some mention
of this being an entropy problem. I tried pinging the board, but that didn't
seem to help.

Any idea why this would suddenly start with the same basic setup that worked
before?
How do I get it to finish generating the key?

Sounds odd - Could you add strace and check what it's busy doing?
