Execstack is a great tool for learning and training on Linux. It is a program which sets, clears, or queries the executable stack flag of ELF binaries and shared libraries. When I was looking to install it I took me a bit to find which package to install it in.

You can install with :

Ubuntu

$ sudo apt-get install prelink

Arch Linux

# important: pass (name, value) pairs as a tuple/sequence not as keyword args!
# otherwise, order will not be preserved.
fields = OrderedDict((('foo', "bar"), ('spamm', "eggs"), ('ham', None)))
T = partial(namedtuple("T", fields), **fields)
t1 = T()
print(t1)
t2 = T(ham="bacon")
