tmate -- Instantly Share Your Terminal Session To Anyone In Seconds
|
||||
=================
|
||||
|
||||
A while ago, we wrote about
|
||||
[teleconsole](https://www.2daygeek.com/teleconsole-share-terminal-session-instantly-to-anyone-in-seconds/)
|
||||
which is used to share terminal instantly to anyone (whoever you trusting). Today also we are going to discuss about same kind of
|
||||
application called tmate.
|
||||
|
||||
Why you want tmate application? this will help you to get help from your
|
||||
friends when you need.
|
||||
|
||||
### What Is tmate?
|
||||
|
||||
[tmate](https://tmate.io/) stands for teammates, it's a fork of tmux,
|
||||
and uses the same configurations such as keybindings, color schemes etc.
|
||||
It's a terminal multiplexer with instant terminal sharing. it enables a
|
||||
number of terminals to be created, accessed, and controlled from a
|
||||
single screen, that can be shared with another mates.
|
||||
|
||||
You can detach the session by leaving the job running in background and
|
||||
re-attach the session when you want to view the status. tmate provides
|
||||
an instant pairing solution, allowing you to share a terminal with one
|
||||
or several teammates.
|
||||
|
||||
A status line at the bottom of the screen shows information on the
|
||||
current session, such as ssh command to share with your mate.
|
||||
|
||||
### How tmate works?
|
||||
|
||||
- When launching tmate, an ssh connection is established to tmate.io
|
||||
(backend servers maintained by tmate developers) in the background
|
||||
through libssh.
|
||||
- The server (tmate.io) ssh key signatures are verified during the DH
|
||||
exchange.
|
||||
- The client is authenticated with local ssh keys.
|
||||
- Once connection is established, a 150 bits (non guessable random
|
||||
characters) session token is generated by local tmux server.
|
||||
- teammates can connect to tmate.io using the SSH session ID provided
|
||||
by user
|
||||
|
||||
### Prerequisites for tmate
|
||||
|
||||
Generate SSH key as a prerequisites since tmate.io server authenticate
|
||||
client machine through local ssh keys. Make a note, every system should
|
||||
have SSH key.
|
||||
```shell
|
||||
$ ssh-keygen -t rsa
|
||||
Generating public/private rsa key pair.
|
||||
Enter file in which to save the key (/home/magi/.ssh/id_rsa):
|
||||
Enter passphrase (empty for no passphrase):
|
||||
Enter same passphrase again:
|
||||
Your identification has been saved in /home/magi/.ssh/id_rsa.
|
||||
Your public key has been saved in /home/magi/.ssh/id_rsa.pub.
|
||||
The key fingerprint is:
|
||||
SHA256:3ima5FuwKbWyyyNrlR/DeBucoyRfdOtlUmb5D214NC8 [email protected]
|
||||
The key's randomart image is:
|
||||
+---[RSA 2048]----+
|
||||
| |
|
||||
| |
|
||||
| . |
|
||||
| . . = o |
|
||||
| *ooS= . + o |
|
||||
| . [email protected]*o.o.+ E .|
|
||||
| =o==B++o = . |
|
||||
| o.+*o+.. . |
|
||||
| ..o+o=. |
|
||||
+----[SHA256]-----+
|
||||
```
