10장. 스마트 카드로 인증 문제 해결

프로세스

1. lsusb 명령을 사용하여 스마트 카드 리더가 운영 체제에 표시되는지 확인합니다.

   $ lsusb
   Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
   Bus 001 Device 003: ID 072f:b100 Advanced Card Systems, Ltd ACR39U

   RHEL에서 테스트 및 지원되는 스마트 카드 및 리더에 대한 자세한 내용은 RHEL 10의 스마트 카드 지원을 참조하십시오.

2. pcscd 서비스 및 소켓이 활성화되어 실행 중인지 확인합니다.

   $ systemctl status pcscd.service pcscd.socket

3. p11-kit list-modules 명령을 사용하여 스마트 카드에 구성된 스마트 카드 및 토큰에 대한 정보를 표시합니다.

   $ p11-kit list-modules
   p11-kit-trust: p11-kit-trust.so
   [...]
   opensc: opensc-pkcs11.so
       library-description: OpenSC smartcard framework

4. 스마트 카드의 콘텐츠에 액세스할 수 있는지 확인합니다.

   $ pkcs11-tool --list-objects --login
   Using slot 0 with a present token (0x0)
   Logging in to "MyEID (sctest)".

5. certutil 명령을 사용하여 스마트 카드의 인증서 내용을 표시합니다.

   1. 다음 명령을 실행하여 인증서의 올바른 이름을 확인합니다.

      $ certutil -d /etc/pki/nssdb -L -h all
      
      Certificate Nickname                                         Trust Attributes

   2. 스마트 카드에 인증서 내용을 표시합니다.

      참고

      이 예제 MyEID(sctest):Certificate 에서는 인증서 이름이 이전 단계에 표시된 출력과 정확히 일치하는지 확인합니다.

      $ certutil -d /etc/pki/nssdb -L -n "MyEID (sctest):Certificate"
      
      Enter Password or Pin for "MyEID (sctest)":
