Remote terminal access with tmate

tmate

tmate is a great tool to remotely let access to someone else in a terminal. This is particularly useful for third party support.

To allow access on a terminal on the raspberrypi follow these steps below.

First install tmate

sudo apt-get install tmate

Then generate keys. Press return when prompted.

ssh-keygen -t rsa -b 4096

The prompt below will appear:

Enter file in which to save the key (/home/pie/.ssh/id_rsa):

Just press enter without giving any input.
Same thing when it asks for a password twice. Just press enter. (or do enter a password if you wish)

Run with the command below

tmate

The following text will appear in the terminal

Tip: if you wish to use tmate only for remote access, run: tmate -F                                            [0/0]
To see the following messages again, run in a tmate session: tmate show-messages
Press  or <ctrl-c> to continue
