Der Artikel ist ziemlich gut, aber ich möchte hier weniger den Autoren danken, sondern vielmehr den Übersetzern, die dadurch wohl die deutsche Text-Referenz für dieses Thema geschaffen haben, zwar sind diese Dinge wohlbekannt und auch relativ leicht, durch ihre starke Verbreitung dank Phrack, w00w00, l0pht a.k.a @stake etc. aber ein entsprechender deztscher Text als Antwort fehlte.

Hello,
Great tutorial, thx for translating to dutch.
Every examples worked fine for me until.........
When i do "gcc -o shellcode4 shellcode4.c" the following warning and error
sow up:
-------
/tmp/ccmTgL5H.s: Assembler messages:
/tmp/ccmTgL5H.s:23: Warning: using `%al' instead of `%eax' due to `b' suffix
/tmp/ccmTgL5H.s:44: Error: invalid character '_' in mnemonic
-------

2 David:

Line 23: It means that instruction "movb" want 8bit source register, but %eax is not.
Line 44: This line wrong. Try to write "call subroutine" instead of "subroutine_call"
