The Lish Console, also called the Linode Shell, provides direct console access to all of your Compute Instances. Through Lish, you can easily access your Compute Instance’s internal Linux system and run commands, install software, or configure applications. Lish is especially useful when you are not able to connect to your server through other means, such as SSH.

Access Lish

There are two ways to access Lish. You can use a terminal application to connect to a Lish SSH gateway, or you can log in to the Linode Cloud Manager and use the Lish console in your web browser. This section explains both methods.

Note
Lish used to be accessible via a direct SSH connection to your Linode’s host machine, but as of May 10, 2013, all users must connect to a Lish SSH gateway to access Lish. For more information, please see this blog post.

Through the Cloud Manager (Weblish)

You can connect to Lish using a web browser. This is useful when you don’t have access to a terminal application, or if you just need quick and easy console access from the Cloud Manager.

  1. Log in to the Cloud Manager.

  2. Click on the Linodes link in the sidebar and select the desired Compute Instance.

  3. Click on the Launch LISH Console link in the top right-hand corner of the Cloud Manager.

  4. The Lish Web Console window appears, as shown below. From here, you can log in to your Compute Instance with any other username and password available on that system (such as root).

You can exit to the Lish prompt by pressing CTRL+A then D. You cannot exit to a Lish gateway box using your web browser. To exit the session entirely, just close the Lish Web Console window.

Through SSH (Using a Terminal)

You can connect to Lish with the SSH client of your choice. For example, you can use the Terminal application in Mac OS X, PuTTY in Windows, or your favorite X11 terminal emulator.

Note
If you have Third Party Authentication enabled on your account, you will not be able to log in to your Compute Instance through Lish with password authentication, and must instead use SSH key authentication. Read the Add Your Public Key section for more instructions on how to add an SSH key to your account for use with Lish.

  1. Determine which Lish SSH gateway you wish to use. There’s one in every data center. See Lish Gateways for a full list.

  2. Open a terminal window and enter the following command, replacing username with your Cloud Manager username, and location with your preferred Lish SSH gateway.

    ssh username@location

    For example, logging in as user via the Newark gateway would look like:

    ssh user@lish-newark.linode.com
    Note
    Users who have been granted “Access” rights on a particular Compute Instance will have access to its Lish console via the gateway. Linodes that a user can’t access in the Cloud Manager won’t show up in the Lish list. For more information about creating user accounts and configuring permissions, see Accounts and Passwords.

  3. Verify that the Lish SSH gateway’s fingerprint is valid by verifying the Terminal’s output against the list of our Lish Gateway Fingerprints. Once verified, enter yes to proceed.

    The authenticity of host 'lish-newark.linode.com (66.228.40.59)' can't be established.
ECDSA key fingerprint is SHA256:57OGBNARJ1fhI+zrE3eTEeQWXVVDHRU8QHcP+BsWmN8.
Are you sure you want to continue connecting (yes/no)?

    If after verifying the authenticity of the Lish SSH gateway’s fingerprint, you receive a message indicating that the ECDSA host key differs from the key for the IP address, remove the cached IP address on your local machine. Ensure you replace 192.0.2.0 with the IP address indicated by the Terminal.

    ssh-keygen -R 192.0.2.0

    Once you have removed the cached IP address, you can again attempt to SSH into the Lish gateway.

  4. Enter the password you use to log in to the Cloud Manager. You are now at the Lish shell. A list of your Compute Instances appears, as shown below:

    Linodes located in this data center:
linode241706         Newark, NJ
linode276072         Newark, NJ

Linodes located in other data centers:
linode287497         Dallas, TX
    Note
    You can add a public SSH key for Lish in the Cloud Manager to automatically connect to Lish without a password. See this section for more information.

  5. At the Lish command prompt, type a Compute Instance’s name from the list. For example, typing linode241706 will connect you to the screen console session for that Instance.

  6. Log in to the system with your username and password.

After you log in, you’ll have console access to your Compute Instance. You’ll be able to restart services like sshd, edit firewall settings, and make other changes. To exit the console, press CTRL+A then D to return to the host machine, and then press CTRL+D to return to the Lish menu. If you’d like to see the list of your Compute Instances again, type list from the gateway.

Add Your Public Key

If you don’t want to enter your password every time you connect to Lish, or if you have Third Party Authentication enabled on your account, you can add your public SSH key to the Linode Cloud Manager. If you haven’t yet created SSH keys, please see our Public Key Authentication with SSH guide for more information.

  1. Log in to the Cloud Manager.

  2. Click on the profile icon in the top right hand corner of the Manager and select LISH Console Settings.

  3. Copy your public SSH key into the SSH Public Key field, as shown below.

  4. Click the Save button. Your Lish key will be saved in the Cloud Manager.

Now you can log in to any of the Lish gateway boxes without having to type your password.

If you wish to disable Lish access for users without keys, use the Authentication Mode dropdown menu on the same page, and select Allow key authentication only then click Save.

Lish Commands

The Lish shell provides access to many functions which are otherwise only accessible via the Cloud Manager web-based administration tool. Enter the help command to see a full list of available commands. The output provides an introduction to Lish functionality:

kill            - kill stuck screen sessions
exit            - exit from lish
help            - this menu

[return]        - connect to console
version         - display running kernel version
boot            - boot last used (or the only) config profile
boot N          - boot the specified config profile
shutdown        - shut down the Linode
reboot          - shut down, then boot the last used config profile
reboot N        - shut down, then boot the specified config profile
sysrq X         - send SysRq X to your Linode
destroy         - pulls the plug on a running Linode, no fs sync, no warning

jobs            - view the job queue for your Linode
configs         - view the configuration profiles for your Linode
config N        - view configuration profile details for profile N
status          - view the status of your Linode
logview         - view contents of console log

There are two ways to run these commands for a specific Compute Instance. If you are at the main Lish gateway, you can prefix the command with a ID, like this:

linode123456 logview

You can also bring up the Compute Instance’s console, then type CTRL+A then D to drop back to the host for that Instance. Now all of the commands above will be run for that Instance specifically. To exit back to the main Lish menu, type exit.

Note
You can activate the ability to scroll back through the Lish console by pressing CTRL-A + ESC

Advanced Lish Tricks

While the Lish interface as described above is useful as a basic command-line interface, you may find that you want to issue commands to your Compute Instance without going through the Lish login process.

You can directly connect to a Compute Instance’s console:

ssh -t [manager-username]@lish-[location].linode.com [linode-name]

You can also append Lish commands to the SSH command on your system prompt. For instance, to reboot your system, using your Cloud Manager username, location, and the host-id for your Compute Instance:

ssh -t [manager-username]@lish-[location].linode.com [linode-name] reboot

Similarly, you can generate a view of the log using Lish:

ssh -t [manager-username]@lish-[location].linode.com [linode-name] logview

This command format works for all Lish functionality.

Lish Gateways

Each data center has its own gateways, which provides access to Lish, Weblish, and Glish. When connecting through Lish, you can use the corresponding gateway within any data center, though we recommend choosing the data center the instance is located within. These gateways are accessible over IPv4 and IPv6.

Note

If you are having issues accessing Lish, Weblish, or Glish, you may be blocked by a local firewall. Make sure your firewall allows outbound connections to the following ports and the gateway you wish to access:

  • Lish ports: 22, 443, 2200
  • Weblish port: 8181
  • Glish port: 8080
