Scep
These scenarios show how to configure the SCEP protocol to retrieve certificates from a PKI server.
Test SCEP Protocol With Linux PKI
Description
In this scenario, the SCEP protocol is used to retrieve digital certificates (X509) from a Linux PKI server.
Scenario
Step 1: Set the following configuration in DUT0 :
set interfaces ethernet eth0 address 10.215.168.64/24 set protocols static route 192.168.212.0/22 next-hop 10.215.168.1 set system certificate scep csr CSR cgi-path /scep set system certificate scep csr CSR cipher aes set system certificate scep csr CSR digest sha256 set system certificate scep csr CSR distinguished-names CN=MyUserCert set system certificate scep csr CSR encrypted-password U2FsdGVkX1/ldbgqi6NNeg4SlT8TPTECgJrp3hKwLPc= set system certificate scep csr CSR port 8080 set system certificate scep csr CSR url 'http://10.215.168.1' set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 2: Ping IP address 10.215.168.1 from DUT0:
admin@DUT0$ ping 10.215.168.1 count 1 size 56 timeout 1Show output
PING 10.215.168.1 (10.215.168.1) 56(84) bytes of data. 64 bytes from 10.215.168.1: icmp_seq=1 ttl=64 time=0.144 ms --- 10.215.168.1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.144/0.144/0.144/0.000 ms
Step 3: Run command pki scep show CSR at DUT0 and check if output matches the following regular expressions:
ca\s+Valid usercert\s+ValidShow output
------------------------------------------------------------------------------------------------- Certificate Status Usage NotBefore NotAfter ------------------------------------------------------------------------------------------------- ca Valid Encipherment & Signature Apr 16 09:19:39 2025 GMT Apr 11 09:19:39 2045 GMT usercert Valid - Jun 20 13:23:26 2025 GMT Jun 20 13:23:26 2026 GMT
Step 4: Run command pki show certificate running://auth/certificates/scep/CSR/ca/ca.der at DUT0 and check if output contains the following tokens:
