Ssh Key Exchange
Test suite for validating SSH access control options
SSH Connection Key Exchange
Description
Sets the SSH service with a single key exchange algorithm
(curve25519-sha256) and checks that the client can connect to the
remote server with that algorithm. Later, checks that using a
different algorithm fails.
Scenario
Step 1: Set the following configuration in DUT0:
set interfaces ethernet eth0 address 10.215.168.20/24 set service ssh key-exchange curve25519-sha256 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=0.358 ms --- 10.215.168.20 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.358/0.358/0.358/0.000 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 key-exchange curve25519-sha256Show 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 key-exchange diffie-hellman-group14-sha1
SSH Connection Key Exchange (multiple)
Description
Sets the SSH service with multiple key exchange algorithms
(curve25519-sha256 and diffie-hellman-group-exchange-sha256)
and checks that the client can connect to the remote server with those
algorithms. Later, checks that using a different algorithm fails.
