Re: [lfs-chat] Wireless home LAN - WiFi vs Bluetooth?
Hi, Initially whatever Debian defaults to when intentionally isolated from the internet. The initial motivation for all this was to eliminate "sneaker-net". I want convenient file sharing between pairs of machines more than among a collection of machines. I'd still very much recommend associating two machines to the portable hotstop that you mentioned you have. When you've done that see if you can get the ping utility to send packets between them. If that works look at something like sftp or a simple script like the one below on one side and a regular web browser on the other: - $ more ~/bin/pyserv #!/bin/sh python -m SimpleHTTPServer - This two line script starts a web server that listens on port 8000. It just serves up the files in under the directory you start it from. Access it from the other machine by pointing a web browser at http://:8000/ Best wishes, @ndy -- andy...@ashurst.eu.org http://www.ashurst.eu.org/ 0x7EBA75FF -- http://lists.linuxfromscratch.org/listinfo/lfs-chat FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page

To the best of my knowledge it is not possible to run a WiFi on multiple
frequencies simultaneously nor to connect to multiple SSIDs
simultaneously. (Analogously you can't plug two cables into the same
Ethernet card.)
However it is possible to have multiple IP subnets on the same SSID,
though I don't really see the point in this peer-to-peer setup.
What application-level interfaces will you use to actually *use* the
network? (FTP? Web? 9P2000? NFS? Gopher? gRPC? Whatever Bluetooth uses?)
Long-term - ?

Firstly you need to get connected to you WiFi...
On top of that you need your IP layer. Given your peer-to-peer use
case, there is no DHCP so you either need to allocate fixed IP addresses
or go with zeroconf addressing
(https://en.wikipedia.org/wiki/Zero-configuration_networking).
Only once you have IP connectivity (verified by ping or so) then you
come to the application-level question. I would suggest the easiest and
most flexible to get started (and to match your sneaker-net replacement
requirement) is to run an SSH daemon on each node, generate
private-public SSH key pairs and use SFTP or SCP. But that is certainly
not the only possibility.

The question of "WiFi or Bluetooth" has become moot. Not all of my

Not a problem. My immediate project's goal is educational.
My learning style is experimenting. Failures are assumed ;}
My solution is to rigidly isolate test machines from internet.
Reading questions that may help:
How to connect two hosts using Bluetooth that does not require them to
be in a master-slave relationship?
Bluetooth may now be moot. But not having a fixed master-slave
relationship is important. {e.g. the topology/protocol described at
https://en.wikipedia.org/wiki/Personal_area_network
which leads to "Wireless ad hoc network" related links starting at

The primary difference between Bluetooth and WiFi ... Bluetooth option has been eliminated as I've discovered a 2nd machine in my collection does not have it. The main challenge that I see in your setup is connecting the network to the outside world. [snip] That is a non-issue as I connect to the internet via a T-Mobile Hotspot (a USB device) used as a "cell modem). If I want internet on one of my secondary machines (an atypical case) I'll just plug it into that machine.

How to connect one WiFi interface to multiple networks? (If you find out, please post the answer here. xD ) That was not in my plans as the combination of WiFi AND being internet connected I consider a NO-NO for my primary machine. But some diagnostics which have been suggested would best be done on machines with nothing but a minimal Debian install. I've two used laptops purchased specifically for experimentation. We'll see what develops. Encryption on Bluetooth? How to route L3 traffic (IP network) over Bluetooth? (This question assumes you *want* to spread an Intranet over your machines.) Not sure how to answer. What I envision would be any two machines communicating as peers. What application-level interfaces will you use to actually *use* the network? (FTP? Web? 9P2000? NFS? Gopher? gRPC? Whatever Bluetooth uses?) I don't know. All I know at this point is I want to avoid any fixed client/server or master/slave relationship. -- http://lists.linuxfromscratch.org/listinfo/lfs-chat FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page

Can you use the hotspot as an access point? Often they work for a

It's poorly documented. I suspect it is intended to connect any WiFi

of communication among machine ;{
Thanks.

My primary question is "What should I be reading?" in order to ask appropriate questions. Specifically "What?" and "Why?" much more than "Howto?". A concern is security issues. Bluetooth, being short range, may thus have an advantage. Speed is not an issue for my expected usage. (I was one of my ISP's last 6 dial-up clients ;) UPDATE: Since originally posting the above, I'm focusing more on a WiFi than Bluetooth solution. Although I did find a Bluetooth article which gave a reasonably good description the topology/protocol I envisioned. https://en.wikipedia.org/wiki/Personal_area_network says in part: A Bluetooth WPAN is also called a piconet, and is composed of up to 8 active devices in a master-slave relationship (a very large number of additional devices can be connected in "parked" > mode). The first Bluetooth device in the piconet is the master, and all ther devices are slaves that communicate with the master.
