Hi all,
Following up on a 6 month or so old inquiry...
My request had been to get to my desktop session of X remotely. I seldom
use this (mosh is typically more than enough) but occasionally it can be
handy - e.g. grabbing a password I forgot to move out from FireFox into
KeyPassXC, etc. (I do use FF sync, but not for passwords...call me
paranoid - I don't mind).
I ended up going with John's suggestion: something VNC-based. While you
can set up Xvnc itself for a separate session, I prefer not to do this
(nor do I need/want a Display Manager remotely). I only wanted on-demand
access to the desktop shown (i.e. what's on the local monitor), and have
found TigerVNC to be a good fit for this.
Setup...
"Client" = laptop on the road, "Server" = the desktop @ home
Client setup: while you can use `ssh -L etc.` to set up port forwards, I
prefer just using ~/.ssh/config, to which I added something like this:
```
Host my_server # the alias I'm using for the server system
LocalForward 5900 127.0.0.1:5900 # forward local port 5900 to
127.0.0.1:5900 on the server site
HostName xxx.xxx.xxx.xxx # IP or fqdn of server system
```
So, my laptop's localhost:5900 is now forwarded (through SSH) to the
server system's equivalent of 127.0.0.1:5900. You can of course change
the ports as needed, but as I do not run an VNC server process on my
laptop, this is fine for me.
This is where Tiger's*x0vncserver* comes in (*x11vnc* is another
alternative). From `man x0vncserver`:
x0vncserver is a TigerVNC Server which makes any X display
remotely accessible via VNC, TigerVNC or compatible viewers. Unlike
Xvnc(1), it does not create a virtual display. Instead, it
just shares an existing X server (typically, that one connected
to the physical screen).
Just what I wanted! Once I have connected via SSH, to the server system,
I start vnc on the server with ` x0vncserver -localhost -SecurityTypes
none -display=:0`. This only listens on localhost, disabling security,
and shares out from display :0, which is my normal i3/X11 desktop. There
are a few additional security options with tigervnc, but I'm just
relying on SSH in this case.
Finally, I connect to my desktop from my client machine with `vncviewer
localhost`. You can also just run vncviewer and will be presented with a
GUI for specifying options.
The performance is ...well, about what I expected from VNC at times, but
overall it's been pretty reasonable/good for my limited use cases. A
couple notes specific to me that may apply to you: I normally run a
picom (an X11 compositor) - killing this before connecting is a good
performance choice. Additionally, I disable a monitor with xrandr. The
VNC client works well (when in full screen) with multiple displays by
scrolling following the mouse motion, but it's just less practical IMO
than dropping a monitor.
There are some other options that make this set up even simpler (e.g.
see the `-via` option of vncviewer), but I figured starting with a more
spelled-out example was better. My primary reference was the Arch wiki:
https://wiki.archlinux.org/title/TigerVNC

Chris

I stepped out when the QUIC discussion was going on. This is a good article written by Geoff Huston.

Hey everybody! So the meeting was good, but we need to work some kinks out with the A/V.
The video was good, but the audio was definitely something to be desired.
I'm going to work on getting some better omni directional mics for future meetings.
Beyond that we had a very interesting conversation about the future of wifi with the 6e and 7 standards.
We also delved a bit into some FOSS alternatives to popular commerial products like discord and options for unencumbered music players.
Later,
Tim.

I was just looking at Best buy has a free standing omni directional
microphone for $50 bucks. That's definitely within my budget.
So the December meeting isn't going to work on the second Thursday of the
month because it directly conflicts with Christmas concerts.
We *could* do the 15th if that would work with everybody.

Sorry I missed the meeting, hopefully I'll be there in December.
Let's nail down a date/time/place early if we can! Wednesday doesn't
really work for me though...

One of those flat mics that sit on the desk/floor might be a good
idea. Or an old plantronics or whatever the name of the octopus like
three armed conference call phones was called.

I've beeen hearing alot of murmurs about Mastodon as an alternative
for Twitter (which I never use) in some cases. I'm just enjoying
watching the dumpster fire over there.
Elon is a smart smart engineer, but he's also a doofus.
John
No worries. We did more talking about a whole range of stuff including the
new wifi standard stuff than the pi music player.
Also, if you did show up virtually, you'd have been frustrated. The room
was way too big for the dinky mic I brought.
I'm going to have to buy a good omni mic that I can put on a tripod in the
middle of the room. Possibly a lav mic for the person speaking as well.
Next month we will have a more organized presentation. Keegan, one of the
guys who's new to the group had a bunch of great suggestions so it'll be a
much better presentation for it.
In talking to the people in the room, the idea of a stand alone FOSS music
player was appealing to everybody.
Also, John redoing his KiCAD demo was of interest as well.
Tim.
