general TCOS question

[Stefan Krümmel]

Hi,
i'm having some problems with my Netkey/TCOS 2.0.3 cards:

when i try to delete the default files on my netkey card with 
opensc-explorer-wk, i only get error messages that say it'Äs not allowed.

eg:

#### opensc-explorer log start ####

#>opensc-explorer
OpenSC Explorer version 0.6.1-wk-20020415
Connecting to card in reader CT-API 
/usr/local/towitoko/lib/libtowitoko.so, port1...
Using card driver: TCOS 2.0 cards

OpenSC [3F00]>ver CHV0 04:05:06:07:08:09:11
Code correct.
OpenSC [3F00]> cd df02
OpenSC [3F00/DF02]> ls
iso7816.c:88:iso7816_check_sw: File not found (red color)
FileID Type Size

  648F   wEF  10
  5083   wEF  18
  5080   wEF  18
  474F   wEF   8

OpenSC [3F00/DF02]> del 448e
card-tcos.c:65:tcos_check_sw: Command not allowed (red color)
card.c:487:sc_delete_file: returning with: Unknown reply from Smartcard
DELETE FILE failed: Unknown reply from Smartcard

OpenSC [3F00/DF02]> del 648f
[same errmsg]

OpenSC [3F00/DF02]> del 648f
[same errmsg]

OpenSC [3F00/DF02]> del 5083
[same errmsg]

OpenSC [3F00/DF02]> del 5080
[same errmsg]

OpenSC [3F00/DF02]> del 474f
[same errmsg]

OpenSC [3F00/DF02]> quit   *grrrr*

#### opensc-explorer log end ####


so what is my basic error that i can't delete any files at will after a 
successfull authenication with CHV0 with is already changed from nullpin 
to my preferred value.


another problem is that i can't access the CHV3,
Werner mentioned that i could change it with CHV0,
but the EF_pinadmin(5003) can only be changed if u know CHV3 ;-((
like KF_NKS2000_20.pdf says in paragraph 4.3.2.4, so what can i do..?

TIA
Stefan
