genpmk bufffer overflow/ abort

[sem1845]

This is what I get when trying to create a new table. I've looked over most of the threads that have "genpmk" in them and haven't found any help. Thanks

Looks like you are using ubuntu and not backtrack.

[sem1845]

I am but this forum seems like it would have more knowledge on dealing with genpmk

[lupin]

Try this on BackTrack 4 PF and post back if you get the same error. We don't support Ubuntu.

Like lumpin said it works on backtrack. It requires a patch to function properly which we have written and applied in our version.

But since it Christmas and all I'll give you the patch to fix yours.

EDIT: In anticipation of your next question I went ahead a wrote a how to on a question/answer site that I write for since its not backtrack related.
