Einleitung
Was wird gebraucht - Hardware?
- Cardreader (z.B. Omnikey Cardman 2020 USB, http://www.omnikey.com/)
- Smartcard (z.B. Schlumberger Cryptoflex 32k e-gate, http://www.axalto.com/)
Was wird gebraucht - Software?
- SuSE 9.3 Professional
http://www.novell.com/products/linuxprofessional/downloads/ftp/germ_mirrors.html - Treiber (Kernelmodul) für den SmartCard Reader
http://www.omnikey.com/ - Support - Downloads - OpenCT 0.6.2-4 (schon enthalten)
- OpenSC 0.9.6 (das bei SuSE 9.3 enthaltene OpenSC 0.9.4-4 ist kaputt)
http://www.opensc.org/download.php - pam_PKCS11
http://www.opensc.org/pam_pkcs11/- pam-devel (schon enthalten)
- openldap2-devel (schon enthalten)
- PCSC-Lite 1.2.9 Beta 6 (schon enthalten)
- openssl 0.9.7e-3 (schon enthalten)
- Apt for SuSE (nicht notwendig, aber sehr praktisch)
http://linux01.gwdg.de/apt4rpm/ - stow (nicht notwendig, aber sehr praktisch)
http://www.gnu.org/software/stow/stow.html
Installation
SuSE
- SuSE 9.3 Standard-Installation mit: KDE, C/C++ Devel, Kernel sources, Erfahrener Benutzer
- Onlineupdate
- Reboot (wg. Kernelupdate)
apt4suse
cd wget http://linux01.gwdg.de/~scorot/install-apt4suse.rpm rpm -Uvh install-apt4suse.rpm install-apt4suse
stow
Da wir keine aktuellen RPMs von OpenSC und pam_PKCS11 für SuSE gefunden haben und es uns auch nicht gelungen ist welche zu erzeugen, benutzten wir im folgenden Stow:
GNU Stow is a program for managing the installation of software packages, keeping them separate (/usr/local/stow/emacs vs. /usr/local/stow/perl, for example) while making them appear to be installed in the same place (/usr/local).[1]
apt-get install stow mkdir /usr/local/stow
omnikey
- Download: http://www.omnikey.com/ - Support - Downloads
- Installation mit Parameter -nopcsc, da die Prüfung, ob PCSC schon enthalten ist, bei beta6 fehlschlägt
cd tar xfz cm2020_installer_v2_4_0_src.tar.gz cd cm2020_installer_v2_4_0_src install -nopcsc
opensc
cd wget http://www.opensc.org/files/opensc-0.9.6.tar.gz tar xfz opensc-0.9.6.tar.gz cd opensc-0.9.6 ./configure --prefix=/usr/local/stow/opensc-0.9.6 make make install cp etc/opensc.conf /etc/opensc.conf cd /usr/local/stow/ stow opensc-0.9.6 mkdir /usr/local/stow/opensc-0.9.6/etc ln -s --backup /etc/opensc.conf /usr/local/stow/opensc-0.9.6/etc/opensc.conf
Pfad in /etc/opensc.conf wie folgt anpassen:
profile_dir = /usr/local/share/opensc
openssl
mkdir /etc/openssl /etc/openssl/certs /etc/openssl/crl /etc/openssl/private /etc/openssl/pkcs12 chmod 700 /etc/openssl/private/ chmod 700 /etc/openssl/pkcs12/
die Datei /etc/ssl/openssl.cnf anpassen
[ CA_default ] dir = /etc/openssl
[ req ] req_extensions = v3_req [ v3_req ] basicConstraints = critical,CA:FALSE
pam_PKCS11
apt-get install pam-devel openldap2-devel cd wget http://www.dit.upm.es/~jantonio/pam-pkcs11/downloads/pkcs11_login-0.5.1.tar.gz tar xfz pkcs11_login-0.5.1.tar.gz ./configure --prefix=/usr/local/stow/pkcs11_login-0.5.1 make make install mkdir /etc/pkcs11 cp etc/pam_pkcs11.conf.example /etc/pkcs11/pam_pkcs11.conf cd /usr/local/stow/ stow pkcs11_login-0.5.1
pam_pkcs11.conf editieren und alle Pfade anpassen: /usr/ -> /usr/local/
use_first_pass = true; ca_dir = /etc/openssl
