Thread: Linux help needed - make fun of the N00b

I've never tried this, but it should be possible, you can create a qemu virtual machine with the arm arch on your x86 desktop. If you need to compile anything, and don't want to mess with crosscompiling (which can be fun), it's worth a try. The good thing about web stuff is that you don't have to mess with compiling. But that won't apply to mal's fusion brain driver or any other custom piece you need.

then save it [ctrl+o ctrl+x] then open up your webbrowser and browse over to your plug http://192.168.1.11/test.php if a page with a bunch of text about php comes up you're all set on php!

Okay, I tried the php but there was no directory /var/www/htdocs. It only went to /var/www. I tried creating the directory and putting the file in it, but no dice.

However, I was able to set up my own apache configuration as a test, repoint the server to it, restart the server, and put my own index.html file into it. That all worked but I still had to type the I.P address into it. I'd really rather do something like http://www.ibug.plug, so I tried editing the httpd.conf file and entered "www.ibug.plug:80" but even after restarting the server, that didn't seem to make any difference.

Tomorrow I will try to connect a USB device to it and detect it.

Whatever name you give the server, needs to be setup in DNS.
You can get it to show an html file, but not a php file?
That means php is either not installed or not configured.
Check out this page for installing php:
https://help.ubuntu.com/8.04/serverguide/C/php5.html
After installing, don't forget to restart apache.

try putting in your site file:

Code:

<VirtualHost *:80>
    ServerName *.ibug.plug
    ServerAlias www.ibug.plug
....
</VirtualHost>

That's a rather cool piece of hardware. Am I reading right that it's only 100$ and it's a 1.2ghz processor?

I wonder if a USB Video Card would work with it.....

bugbyte: i think the wed directory might vary by distro, sorry about that, /var/www is the default directory for debian distro's, so to test php you can try what i suggested but just use the /var/www dir not /var/www/htdocs. good luck! also as noted above you'll need dns set up to handle using things http://ibug.plug [or what ever] a quick way to hardcode for test is to put lines in the /etc/hosts files of the plug and all the computers accessing it on the network [might be harder on the iphone, i cant check right now]

kev000: i might try to do a VM install of this, thanks for the idea

Right. I bought it for $99, it runs at 1.2ghz, has 512mb of internal ram, but you can bump that up with an external SD card or USB storage device.

For video, it has something called a Transport Stream video interface. That appears to stand for Transport Stream video. I'm not familiar with it, but GIYF and it appears that you can send video or audio streams over IP with it. So, maybe if you had a webcam plugged into it, you could transmit the picture across the network? Looks like the receiver has to decode the information, so there's some software involved -like a VLC player or something similar?

Still working on the dns thing, but I got php loaded and setup. Ran a test script from the server guide - thanks, PaulF! It does a print_r phpinfo() command and it returned LOADS of useful information like the configuration and environment variables and so on.

1) ssh in run

2) plug in device
3) look at output
4) check dmesg

Code:

dmesg

or

Code:

dmesg|tail -n 30

as dmesg can output a LOT

if it's recognized then it's time to find some applications or hack away to make it do what you want!

It recognized my GPS when I plugged it in.

usb 1-1: new full speed USB device using ehci_marvell and address 2
usb 1-1: configuration #1 chosen from 1 choice
usb 1-1: USB disconnect, address 2
usb 1-1: new full speed USB device using ehci_marvell and address 3
usb 1-1: configuration #1 chosen from 1 choice

And when I disconnected it, it was able to handle that as well. I guess I should try a USB hub to see if it can handle it.
