Authentication Failed

See original GitHub issue

Hello and thank you for this project. I am attempting to scan a RouterOS device running version 7.1.3 and I am getting an authentication failure from paramiko. The RouterOS logs say expected msg: 50 got: 5. After some good old fashioned BING searches I saw similar issues opened with an Ansible module (see here: https://github.com/ansible/ansible/issues/55042). I tried a few suggestions mentioned in that thread but did not find luck. Regular ssh user@address -p 2223 works as expected.

python3 main.py -i 172.16.254.1 -p 2223 -u jared+cet1024w -ps PASSWORD
Mikrotik ip address: 172.16.254.1

You need to set the paramiko parameter “look_for_keys” to false.

Change line 29 in main.py to this: ssh_client.connect(hostname=args.ip, port=args.port, username=args.userName, password=args.password, look_for_keys=False)

@organicnz Looks like you forgot to add allow_agent=False parameter in your ssh_client.connect function ssh_client.connect(hostname=args.ip, port=args.port, username=args.userName, password=args.password, look_for_keys=False, allow_agent=False)

I also have the same problem if you check the log file of mikrotik its clearly being authenticate but there’s something wrong if the routeros-scanner/commands/dns.py
