computing resources aren't really the problem.. It's the configuration 
resources (i.e. time to set up the server and configure it properly).



I've been playing yesterday and today with a variety of the suggestions 
made here and it's been fun.  python -m SimpleHTTPServer is pretty easy, 
after all. (although doesn't do POST, etc.)


A bunch of the choices described here make it pretty easy to fire off 
python or something else.


I haven't tried it on a Raspberry Pi yet, but I've been working with a 
bunch of clunky old PCs I happened to have around.  Tomorrow I'll try a 
couple of them on a 10 year old Via Mini-ITX box with compact flash I 
have in my desk drawer that runs an old Debian distro.  If it runs on 
that, it will run on anything.

Insufficient RAM for what applications? (not argumenting, just curious, since 
it has been running Apache and a couple of services just fine)

I understand 64MB (like the board I use) is a little skimpy by today's 
standards, but when you don't run a GUI, it goes a long way.

Subject: [time-nuts] lightweight webserver for, e.g., NTP widget

I'm intrigued by the possibility of using a lightweight web server to 
provide a management/user interface to test equipment or appliances 
(e.g. like the NTP server recently discussed, or a box with mixers and 
counters).

I've built some web interfaces to very small things using Arduinos and 
Rabbits, and it works ok for simple stuff (turning on and off switches), 
but as soon as you start looking at a bit more complexity (e.g. you want 
to move files around), a bit more sophistication on your server seems 
useful.  Or, for instance, if you have a DDS you want to program to 
follow a particular sequence of frequencies (e.g. to match a particular 
Doppler profile, in my case). Or a data acquisition application.

The appeal that the "user client" is that any old web-browser is pretty 
generic.

I've done this "sort of" by exposing a directory as a public share (SMB) 
and then "browsing" to that file, using the file:// mechanism, but it 
seems that actually having a real server might be useful (for things 
like POST from a form, for instance)

But, on the other hand, it seems that something like Apache is a bit 
much to manage.

Is there something that runs under Linux on a lightweight single board 
PC (Raspberry pi or Intel Mini-ITX Atom mobos) that isn't too much of a 
pain, and doesn't require you to be a full time web server administrator 
to make it work?

Re: [time-nuts] lightweight webserver for, e.g., NTP widget

[gary]

I tend to agree with this notion of not going with the cheapest SBC 
possible. Unless you are going to incorporate the PI in a number of 
devices (i.e. will be buying multiple units), it makes more sense to 
toss in the extra hundred dollars and get a more capable SBC. For one 
thing, you need the serial port on the SBC in the event things go wrong 
with USB.


Regarding running linux on Arm, I've tried a few distributions. By far, 
the easiest to get running is opensuse. However, it seems to be the 
least efficient. XFCE is a bit too much for a single core Cortex, and 
the ICEWM never starts. It is in the image as an alternate window 
manager. Fedora is playing catch up on Arm, but they have the bucks to 
ultimately do a fine job.


Probably the most ready to rock and roll is Ubuntu. Having used Opensuse 
for well over a decade, I have to say Debian is bizarre and Ubuntu is 
cryptic. The lack of a root user account on Debian is a head scratcher, 
though you can add one. But the real killer is the package management on 
Ubuntu. Aptitude is not Yast. In fact, you are better off using the 
package search website that Ubuntu set up than to use Aptitude. Don't 
even get me started on Ubuntu environment variable schemes.


Regarding Ubuntu on ARM, here are some real time savers. Once you 
install the image on a SD card and boot, do the following:

apt-get update
apt-get upgrade

If you are going to install gcc, do this:

apt-get install build-essential


Otherwise, the compiler is installed but the environment variables are 
not. Bizarre to say the least. Without running update and upgrade, when 
I tried to install gcc, it suggested I use "pentium-builder". No, really!


A few other packages that are useful:

apt-get install icewm
apt-get install xorg
apt-get install midori


For unknown reasons, the Xterm on Ubuntu doesn't cut and paste properly. 
There are hints on the internet about how to make it work like "normal" 
linux, but they didn't work for me. However, this terminal works fine 
with cut and paste.

apt-get install terminator


When you install it, the program shows up as "terminal" not 
"terminator." Go figure.


Many of these Arm SBCs do not have a battery for the RTC. On some, there 
is a hook to add a battery. Since most people will have them on a 
network, this sort of makes sense. There could also be issues regarding 
shipping boards with the battery installed. But it seems NTP will not 
set the clock during the installation (first boot). I have no idea why 
this is true, but once booted again, NTP runs. I haven't checked it for 
accuracy.


There is a hardware bug in the Beagleboard XM, so I would suggest not 
buying that SBC. I am trying to patch around it, but a patch is not the 
same as designing the hardware correctly.


As I mentioned previously, some of these SBCs depend on the graphic chip 
to do the heavy lifting. If you are going to do anything computational 
in your own software, get a SBC with a Cortex-A chip. Those chips have 
"dsp", actually SIMD:

http://www.arm.com/products/processors/technologies/dsp-simd.php


For software defined radio, this is at least a factor of two faster in 
my testing, and often three or four depending on the program.

Re: [time-nuts] lightweight webserver for, e.g., NTP widget

[Bill Roy]

If you just want to static-serve the assets in a particular folder, and have 
python available, there's always:

python -m SimpleHTTPServer

…which serves the current directory on localhost:8080.  But no PHP.

For a modern approach you might look at building a small server based on 
Node.js, which is a sort of construction kit for network applications like web 
servers, among other things.  It runs on small linux platforms like the 
Raspberry Pi, as well as the usual desktop systems.  Open source at 
http://nodejs.org

As an example, I publish an open-source Node.js application for controlling the 
Arduino here: 
https://github.com/billroy/bitlash-commander

It's a web server that talks to devices on the serial port and serves control 
panels with status indicators and controls over the web.

Your DDS control example would be easy to implement in a similar way using 
node.  Happy to follow up off-list.

Re: [time-nuts] lightweight webserver for, e.g., NTP widget

[David Armstrong]

There are numberous web servers that are small and light weight, some
examples are boa ( www.boa.org ) and HTTPd
http://www.nongnu.org/mini-httpd/

[time-nuts] lightweight webserver for, e.g., NTP widget

[Jim Lux]

I'm intrigued by the possibility of using a lightweight web server to 
provide a management/user interface to test equipment or appliances 
(e.g. like the NTP server recently discussed, or a box with mixers and 
counters).


I've built some web interfaces to very small things using Arduinos and 
Rabbits, and it works ok for simple stuff (turning on and off switches), 
but as soon as you start looking at a bit more complexity (e.g. you want 
to move files around), a bit more sophistication on your server seems 
useful.  Or, for instance, if you have a DDS you want to program to 
follow a particular sequence of frequencies (e.g. to match a particular 
Doppler profile, in my case). Or a data acquisition application.


The appeal that the "user client" is that any old web-browser is pretty 
generic.


I've done this "sort of" by exposing a directory as a public share (SMB) 
and then "browsing" to that file, using the file:// mechanism, but it 
seems that actually having a real server might be useful (for things 
like POST from a form, for instance)


But, on the other hand, it seems that something like Apache is a bit 
much to manage.


Is there something that runs under Linux on a lightweight single board 
PC (Raspberry pi or Intel Mini-ITX Atom mobos) that isn't too much of a 
pain, and doesn't require you to be a full time web server administrator 
to make it work?
