Re: zenmap as root error

You can just check if the DISPLAY environment variable is set. Like this:

----------------------------------------8<----------------------------------------
import os
import sys

if 'DISPLAY' not in os.environ.keys():

    print "Unable to start graphical application. Please, set DISPLAY \
environment variable."
    sys.exit(0)

import gtk
----------------------------------------8<----------------------------------------

Put this before "import gtk" in zenmap main file to avoid some warnings too.

Att, João Medeiros.

 Hm, thanks for the report.  Zenmap should give a proper error in that
 case, not segfault.  When I unset my display, I get a much more useful
 exception:

 RuntimeError: could not open display

 If anyone else gets the segmentation fault result described above and
 can find a fix, I'd be happy to integrate it.

 Cheers,
