=============================================================================

The Edmonton Linux User Group (ELUG) is a chance to get together with other users of Linux, GNU, and Unix-like operating systems, and open source software. Our members range from newcomers to power users to seasoned administrators and developers; so, all are welcome!

We meet as an opportunity to exchange ideas, knowledge, and experiences for several reasons:

to educate for personal and professional growth
to promote and advocate for free and open source software
to support and assist with Linux related challenges
and to socialize with peers who have common interests

Meetings are held both virtually and in person, usually at Strathcona County Public Library.
We would like to find a more centrally-located and technologically equipped venue within Edmonton proper for the monthly meetings. If you know of a location or have space to offer, please let us know! (Contact info below)

Standard Agenda:

6:00pm – Arrival, random chitchat
6:30pm – Welcome & introductions, topic discussion begins
7:30pm – Announcements, open discussion
8:00pm – Event conclusion

Examples of topics that may be discussed or presented include (but not limited to):

Exposure to different distributions
Workshops on various tools and commands
Applications, development and tuning
just about anything else Linux-related

We welcome anyone with an interest in Linux and/or open source software and look forward to building the Linux community in Edmonton.

ELUG Meetup: 22 August 2024

Topic: tmux
Discussion lead: Robert, and then everyone
Physical location: Strathcona County Public Library, Maple Room; 401 Festival Lane Sherwood Park https://maps.app.goo.gl/yhBzVWn4UoVTGW1T7

tmux is a “terminal multiplexer”, essentially a terminal manager for creating and managing multiple terminal windows within a single environment.

tmux isolates terminals from connection dependencies because the (tmux) terminal process is now on the
remote machine, not on your local machine, i.e. terminal processes can continue running on the remote machine even if your connection to the remote machine is lost.

Usage:

tmux

By default, tmux creates a new “session” = the environment that contains one or more terminals, and creates one terminal in the new session

Multiple terminals/windows/tabs can be started within each session
You can manage how the multiple running terminals are arranged on your screen
Each terminal can be used for a different purpose (connect to another machine, do a task locally,
compile and run a donut-shaped program that displays a spinning ascii-art donut, etc…)
You can replicate processes between terminals, e.g. type a command into multiple terminals at the same time
Each terminal state can be saved, e.g. when it is no longer needed
If you disconnect from the session, the session continues running (because tmux is still running)
If you disconnect your ssh connection, the session continues running (because tmux is still running on
the remote machine)
You can reconnect ssh and reconnect to an existing tmux session at any time

Presenter: Mostly Robin, but there was plenty of banter from several others
Topic: More security topics! public key crypto, ssh, gpg keys
Physical location: Strathcona County Public Library, Maple Room; 401 Festival Lane Sherwood Park https://maps.app.goo.gl/yhBzVWn4UoVTGW1T7

~/.ssh/known_hosts file = list of authenticated server signatures
“I’ve connected to these servers before, and this one matches a signature”
~/.ssh/authorized_keys = list of authenticated public keys
“I’ve authenticated these (users) public keys before, and this user has proven they have a matching private key”

gpg --list-keys
gpg --export-secret-keys

Recommendation: Encrypt personal files with your own private key, so that no one can decrypt anything except you… but then make sure you backup your private key(s)!

Subsequent discussion:

fan speed kernel daemon module (yay Lyndon!)
vitals = package to show system info in top status bar
