expect-2-mikrotik

Automates the task by providing inputs. The expect command is a powerful automation tool used for scripting and automating interactive applications. It is particularly useful for tasks that require a response to prompts, such as login procedures, SSH/FTP interactions, or any other command-line based program that requires user input.

I have imported rsa-key into router (Mikrotik), so I can login without password ask. using this expect script I can login from host Router box into other using mac-telnet.

To generate RSA-Keys

ssh-keygen -f data/id_rsa_router -C "docker"

Files	Type	Description
id_rsa_router	private	very confidential.
id_rsa_router.pub	public	upload into host router and add as SSH keys.

Import to SSH key on router

[admin@mikrotik]> user ssh-keys import public-key-file=id_rsa_router.pub user=admin-ssh

To run command

$ docker exec -it ubuntu_expect18 ./set_remote.sh <ip address of host Router> <mac to connect to> <ip address to set on interface with mac>
