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/tAL6zswySQrFihI4xd9SkPnpA2H2PM1E=
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 1
Show 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=0.162 ms

1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.162/0.162/0.162/0.000 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+Valid
Show output
-------------------------------------------------------------------------------------------------
Certificate  Status           Usage                   NotBefore                  NotAfter

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:

Subject: CN = Teldat-PKI, O = Teldat, L = Madrid, C = ES
Show output
