Ansible-galaxy install arista.eos-interfaces Requirements. Requires an SSH connection for connectivity to your Arista device. You can use any of the built-in eos connection variables, or the convenience provider dictionary. Role Variables. The tasks in this role are driven by the interfaces object described below. 19.1 HTTPS Certificates Setup. CVP uses nginx to front and terminate all HTTPS connections. To support HTTPS, the server must be configured with a certificate. A self­signed certificate is generated at first bootup. To install your own certificate and key, copy the certificate to the following location on CVP.

To create a public key pair, run ssh-keygen-g3 on Client:

  • This module provides declarative management of the local usernames configured on Arista EOS devices. It allows playbooks to manage either individual usernames or the collection of usernames in the current running config. It also supports purging usernames from the configuration that are not explicitly defined. Specifies the SSH public key.
  • When using the ansible-playbook -diff command line argument the module can generate diffs against different sources. Specifies the SSH keyfile to use to authenticate the connection to the remote device. Arista EOS device config has 3 spaces indentation.

N can be provided by eos local configuration or TACACS+. The XMPP server should use the same authentication source as the switches.

When run without options, ssh-keygen-g3 asks for a passphrase for the new key. Enter a sufficiently long (20 characters or so) sequence of any characters (spaces are OK).

The new authentication key pair consists of two separate files. One of the keys is your private key which must never be made available to anyone but yourself. The private key can only be used together with the passphrase.

On Unix, the key pair is by default stored in your $HOME/.ssh2 directory (created by ssh-keygen-g3 if it does not exist previously). On Windows, the key pair is by default stored in your %APPDATA%SSHUserKeys directory.

In the example above, the private key file is id_dsa_2048_a. The public key file is id_dsa_2048_a.pub, and it can be distributed to other computers.

By default, ssh-keygen-g3 Monster hunter generations ultimate key quests village. creates a 2048-bit DSA key pair. RSA keys can be generated by specifying the -t option with ssh-keygen-g3. Key length can be specified with the -b option. For automated jobs, the key can be generated without a passphrase with the -P option, for example:

You generate an SSH key through macOS by using the Terminal application. Once you upload a valid public SSH key, the Triton Compute Service uses SmartLogin to copy the public key to any new SmartMachine you provision.

Joyent recommends RSA keys because the node-manta CLI programs work with RSA keys both locally and with the ssh agent. DSA keys will work only if the private key is on the same system as the CLI, and not password-protected.

About Terminal

Terminal is the terminal emulator which provides a text-based command line interface to the Unix shell of macOS.

To open the macOS Terminal, follow these steps:

  1. In Finder, choose Utilities from the Applications folder.
  2. Find Terminal in the Utilities listw.
  3. Open Terminal.

Arista Eos Command Reference

The Terminal window opens with the commandline prompt displaying the name of your machine and your username.

Generating an SSH key

An SSH key consists of a pair of files. One is the private key, which should never be shared with anyone. The other is the public key. The other file is a public key which allows you to log into the containers and VMs you provision. When you generate the keys, you will use ssh-keygen to store the keys in a safe location so you can bypass the login prompt when connecting to your instances.

To generate SSH keys in macOS, follow these steps:

  1. Enter the following command in the Terminal window.

    This starts the key generation process. When you execute this command, the ssh-keygen utility prompts you to indicate where to store the key.

  2. Press the ENTER key to accept the default location. The ssh-keygen utility prompts you for a passphrase.

  3. Type in a passphrase. You can also hit the ENTER key to accept the default (no passphrase). However, this is not recommended.

You will need to enter the passphrase a second time to continue.

After you confirm the passphrase, the system generates the key pair.

Your private key is saved to the id_rsa file in the .ssh directory and is used to verify the public key you use belongs to the same Triton Compute Service account.

Never share your private key with anyone!

Your public key is saved to the id_rsa.pub;file and is the key you upload to your Triton Compute Service account. You can save this key to the clipboard by running this:

Arista Eos Configuration Guide

Importing your SSH key

Now you must import the copied SSH key to the portal.

  1. After you copy the SSH key to the clipboard, return to your account page.
  2. Choose to Import Public Key and paste your SSH key into the Public Key field.
  3. In the Key Name field, provide a name for the key. Note: although providing a key name is optional, it is a best practice for ease of managing multiple SSH keys.
  4. Add the key. It will now appear in your table of keys under SSH.

Troubleshooting

You may see a password prompt like this:

This is because:

  • You did not enter the correct passphrase.
  • The private key on your Macintosh (id_rsa) does not match the public key stored with your Triton Compute Service account.
  • The public key was not entered correctly in your Triton account.

What are my next steps?

Right in the portal, you can easily create Docker containers, infrastructure containers, and hardware virtual machines.

In order to use the Terminal to create instances, set up triton and CloudAPI as well as the triton-docker commandline tool.
