Command Line Access to Your Node
|
||
|
|
================================
|
||
|
|
|
||
|
|
There may be times when it would be useful to have command line access to your node. AREDN |trade| nodes support both `Secure Shell (ssh) <https://en.wikipedia.org/wiki/Secure_Shell>`_ and `Telnet <https://en.wikipedia.org/wiki/Telnet>`_. Both access methods will require a set of login credentials (*root* username & password). Linux and MacOS computers have native tools for both *SSH* and *Telnet*.
|
||
|
|
|
||
|
|
The *OpenSSH* package can be enabled on Windows computers. Use a web search engine to find information for your specific operating system (for example search "openssh for windows 10"). Here are some examples for enabling OpenSSH on Windows computers:
|
||
|
|
|
||
|
|
- `Example for Windows 10 <https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse?tabs=gui>`_
|
||
|
|
- `Example for Windows 11 <https://technoresult.com/how-to-install-and-use-openssh-server-in-windows-11/>`_
|
||
|
|
|
||
|
|
On Windows computers you can also use a terminal program such as `PuTTY <https://www.chiark.greenend.org.uk/~sgtatham/putty/>`_ to connect to your node via ssh or telnet. To learn how to use these programs on your computer, please see the appropriate documentation for the specific programs you have chosen.
|
||
|
|
|
||
|
|
As shown in the command line examples below, you begin by opening a terminal window on your computer. At your computer's command prompt, enter the command string you will use to authenticate to your node.
|
||
|
|
|
||
|
|
Telnet
|
||
|
|
*Telnet* will prompt you for the *root* username and password before displaying your node's command prompt. The *telnet* protocol uses well-known port ``23`` and all traffic is unencrypted. An example *Telnet* command string is
|
||
|
|
|
||
|
|
::
|
||
|
|
|
||
|
|
$ telnet localnode.local.mesh
|
||
|
|
|
||
|
|
After successfully authenticating, your node's command prompt will be displayed.

SSH
|
||
|
|
*SSH* requires you to specify the port, *root* username, and password on the command line. This is because AREDN |trade| nodes do not use the default well-known *ssh* port [22], but nodes use port ``2222`` for *ssh* connections. An example *SSH* command string is
|
||
|
|
|
||
|
|
::
|
||
|
|
|
||
|
|
$ ssh -p 2222 root@localnode.local.mesh
|
||
|
|
|
||
|
|
After successfully authenticating, your node's command prompt will be displayed.
