SSH User Deny
Description
Check that enforcing a user denial will work as expected. Test_user is set to be
denied through SSH connection, then a connection through this user is tried expecting
failure to connect. Admin user that hasn’t been denied is also tested to confirm unchanged
behavior in this case.
Scenario
Step 1: Set the following configuration in DUT0 :
set interfaces ethernet eth0 address 10.215.168.20/24 set service ssh access-control deny user test_user set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0' set system login user test_user authentication encrypted-password '$6$BR9X.sXj3WaUbWfa$F3lRSj7JLj0b3gklXk4WzxAqeGfdzZtu2KOSJQMPSMQ1MBmjpaTsFrksf4mk6MXMbMGyHxV7tQkocnGFhIHgm/'
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=0.668 ms --- 10.215.168.20 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.668/0.668/0.668/0.000 ms
Step 4: Init an SSH connection from DUT1 to IP address 10.215.168.20 with the user test_user which is going to fail:
admin@DUT1$ ssh test_user@10.215.168.20 option StrictHostKeyChecking=no option UserKnownHostsFile=/dev/nullShow output
Permission denied, please try again. test_user@10.215.168.20's password:
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/nullShow output

SSH User Allow
Description
Check that allowing a user will only let that user connect to the device.
Test_user is set to be unallowed through SSH connection, then a connection through
this user is tried expecting to connect unsuccessfully. The next step will try a SSH connection
through Admin which is the allowed user, then the connection is succesfull.

SSH Role Deny
Description
Check that enforcing a role denial will work as expected. Test_user and test_role are created
and then the role is assigned to the user. The role is set to be unallowed through SSH connection, then a connection
through this user is tried expecting a failure. The admin user is also tried to ensure that users that haven’t been
denied can still access the router.

SSH Role Allow
Description
Check that enforcing a role permission will work as expected. Two users and two roles are created.
The roles are assigned to each of the users. Test_role is then allowed and an SSH connection is tried
with the test_user assigned that role, expecting to succeed.
Test_user2 is tried to ensure the deny by default behavior once an allow is set.
