Cisco – How to load Scripts into Cisco Routers

automationciscoscripting

I would like to load scripts automatically based on certain triggers/conditions into cisco routers.

Can anyone provide me a link or tell me how to do it?

what does the scripts does?
1. Once the user authenticate to a NAS(cisco router), it will grab its userID and password. Then, it will do background authentication for the next router the users wish to use.
2. The script also will disconnect a user from NAS/cisco router once his timing ends.

I am only interested on how to load the scripts into the router automatically.

I am currently using CISCO ACS for AAA server.
The problem is I am required to do background authentication for users that are stored in SQL.
So, when those users login, their usernames and passwords need to be catched for background authentication.

I need to load the scripts automatically to cisco routers which I am still have no idea on how to do it.

Thank you in advance

Have you considered using Radius or TACACS+ for AuthN/AuthZ? Those will accomplish the same thing as your proposed script, and unlike your script, are well-supported methods by Cisco.

Ssh – How to automate SSH login with password

Don't use a password. Generate a passphrase-less SSH key and push it to your VM.

If you already have an SSH key, you can skip this step… Just hit Enter for the key and both passphrases:

$ ssh-keygen -t rsa -b 2048
Generating public/private rsa key pair.
Enter file in which to save the key (/home/username/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/username/.ssh/id_rsa.
Your public key has been saved in /home/username/.ssh/id_rsa.pub.

Copy your keys to the target server:

$ ssh-copy-id id@server
id@server's password:

Now try logging into the machine, with ssh 'id@server', and check-in:

.ssh/authorized_keys

Note: If you don't have .ssh dir and authorized_keys file, you need to create it first

to make sure we haven’t added extra keys that you weren’t expecting.

Finally, check to log in…

$ ssh id@server

id@server:~$

You may also want to look into using ssh-agent if you want to try keeping your keys protected with a passphrase.
