Hi!

I'm using DirBusbuster in headless mode (-H parameter from command line)
from a remote server in a text terminal. When working with some
directories, DirBuster shows me this exception:

- -------------------------------------------------------------------
Exception in thread "Thread-15" java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation
which requires it.

Doing a little homework i've found that the problem resides on the
matter that the remote text terminal cannot render a form that appears
to be shown on some circumstances. Trying again the same call but from
my local terminal (with graphical interface) and without the "-H"
parameter, i've found that in some point of the scan the application
pops a form saying "Warning - Unable to determine consistent fail
response". This form is used to enter a regular expression to allow
DirBuster to continue working, but the problem is that in headless mode
on a pure text terminal, it throws a java exception (mentioned above)
and i can't manage to input the regex in any way, so the program
execution enters in a loop waiting for some input that will never come
(in some cases, i notices a downgrade of performance in the host).

This is my command line call to the app:

$ java -jar DirBuster-0.12.jar -H -l discovery.txt -g -t 20 -s / -P -u

Is there some way to tell DirBuster about this regex but from "pure"
textmode? Or is there some parameter to archieve this?

Thanks in advance

PD1: Excuse me if something is not understandable; english is not my
natural language.
PD2: DirBuster is a great great tool; keep working that way!
