Ssh Cipher
Test suite for validating SSH cipher options
SSH Connection Specific Cipher
Description
Sets the SSH service to only accept a single cipher (AES256-CBC)
and checks that a client can connect to the remote server using that
cipher. Later on, checks that it cannot connect using a different
cipher.
Scenario
Step 1: Set the following configuration in DUT0:
set interfaces ethernet eth0 address 10.215.168.20/24 set service ssh cipher aes256-cbc set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 2: Set the following configuration in DUT1:
set interfaces ethernet eth0 address 10.215.168.21/24 set service ssh set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 3: Ping IP address 10.215.168.20 from DUT1:
admin@DUT1$ ping 10.215.168.20 count 1 size 56 timeout 1Show output
PING 10.215.168.20 (10.215.168.20) 56(84) bytes of data. 64 bytes from 10.215.168.20: icmp_seq=1 ttl=64 time=0.287 ms --- 10.215.168.20 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.287/0.287/0.287/0.000 ms
Step 4: Init an SSH connection from DUT1 to IP address 10.215.168.20 with the user admin:
admin@DUT1$ ssh admin@10.215.168.20 option StrictHostKeyChecking=no option UserKnownHostsFile=/dev/null cipher aes256-cbcShow output

Step 5: Init an SSH connection from DUT1 to IP address 10.215.168.20 with the user admin:
admin@DUT1$ ssh admin@10.215.168.20 option StrictHostKeyChecking=no option UserKnownHostsFile=/dev/null cipher 3des-cbc
SSH Connection Multiple Ciphers
Description
Sets the SSH service to accept multiple ciphers (AES256-CBC and
AES128-CTR) and checks that a client can connect to the remote
server using any of the two ciphers. Later on, checks that it cannot connect
using a different cipher.
Scenario
Step 1: Set the following configuration in DUT0:
set interfaces ethernet eth0 address 10.215.168.20/24 set service ssh cipher aes128-ctr,aes256-cbc set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 2: Set the following configuration in DUT1:
set interfaces ethernet eth0 address 10.215.168.21/24 set service ssh set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 3: Ping IP address 10.215.168.20 from DUT1:
