			== sprintpcs script ==

			After much experimentation, the: "[http://nst.cvs.sourceforge.net/nst/src/packages/networking/sprintpcs/etc/rc.d/init.d/sprintpcs?view=markup /etc/rc.d/init.d/sprintpcs]" script was created to simplify the process of bringing up a "Sprint Mobile Broadband" connection. The script was designed with the following features:

			* The script reads the configuration file: "[http://nst.cvs.sourceforge.net/nst/src/packages/networking/sprintpcs/etc/sysconfig/sprintpcs?view=markup /etc/sysconfig/sprintpcs]" - mainly to determine what type of modem is being used (currently the '''U680''' is the only supported modem type).

			* The same script and configuration file can be used both on '''NST v1.8.1''', '''Fedora 8''', and '''Ubuntu 8.04'''. The script is likely usable on other Linux distributions as well.

			* For a '''U680''' modem, the first time the script is run, it will create the directory: ''/var/lib/sprintpcs/U680''. It will then install and ''tweak'' the files which come on the '''U680''' flash drive to this directory. NOTE: This means that the '''U680''' flash drive must be mounted the first time the script is used.

			* All subsequent invocations only require that the '''U680''' modem be inserted in the system.

			* A log file: ''/var/log/sprintpcs/U680.log'' is created and one can view this to look for errors.

			* The script waits up to 10 seconds for the connection to be established.

			* After the connection is established (when the primary DNS server appears in the log file), the script will attempt to ping a host on the Internet. If it fails, it will configure the system to use the file: ''/etc/ppp/resolv.conf'' for name resolution.

			=== Installation ===

			==== NST v1.8.1 ====

			Starting with '''NST v1.8.1''', the script should already be installed. The script is not usable on earlier versions of the '''NST''' distribution (unless you manually install the '''wvdial''' package).

			==== Fedora 8 ====

			* Install the [http://nst.cvs.sourceforge.net/nst/src/packages/networking/sprintpcs/etc/rc.d/init.d/sprintpcs?view=markup sprintpcs script] to: ''/etc/rc.d/init.d/sprintpcs''.

			* Install the [http://nst.cvs.sourceforge.net/nst/src/packages/networking/sprintpcs/etc/sysconfig/sprintpcs?view=markup sprintpcs config file] to: ''/etc/sysconfig/sprintpcs''.

			==== Ubuntu 8.04 ====

			* Install the [http://nst.cvs.sourceforge.net/nst/src/packages/networking/sprintpcs/etc/rc.d/init.d/sprintpcs?view=markup sprintpcs script] to: ''/etc/init.d/sprintpcs''.

			* Install the [http://nst.cvs.sourceforge.net/nst/src/packages/networking/sprintpcs/etc/sysconfig/sprintpcs?view=markup sprintpcs config file] to: ''/etc/default/sprintpcs''.


			=== Normal Usage ===

			'''NOTE''': Many '''Fedora''' and '''Ubuntu''' systems use the '''NetworkManager''' service to manage network connections. You may want to disable your network connections (or stop the '''NetworkManager''' service) prior to using the '''sprintpcs''' script.

			==== Starting The Service ====

			<pre>
			[root@sprint ~]# service sprintpcs start
			Starting sprintpcs: U680 ...... [ OK ]
			[root@sprint ~]#
			</pre>

			==== Stopping The Service ====

			<pre>
			[root@sprint ~]# service sprintpcs stop
			Stopping sprintpcs: U680 [ OK ]
			[root@sprint ~]#
			</pre>

			=== First Time Usage ===

			The first time the '''sprintpcs''' script is run on the system, it will attempt to copy files off of the '''U680''' flash drive. By default it expects the flash drive to be mounted at: ''/media/U680_UMSD''. On a standard '''Fedora''' or '''Ubuntu''' installation, this will probably occur automatically. If it doesn't (or your are using a '''NST''' system), you will see a message like the following:

			<pre>
			[root@sprint ~]# service sprintpcs start
			*ERROR* Failed to locate: /media/U680_UMSD/Linux_Ubuntu - try mounting U680 disk
			[root@sprint ~]#
			</pre>

			If you see this message, you will need to:

			* Determine what device is associated with the flash drive. The following shows how '''sdb''' was determined on a '''NST v1.8.1''' system:

			<pre>
			[root@sprint ~]# cd /dev/disk/by-id/
			[root@sprint by-id]# ls usb*
			usb-CMOTECH_Mass_Storage-0:0
			[root@sprint by-id]# ls -l usb* lrwxrwxrwx 1 root root 9 2008-08-19 09:51 usb-CMOTECH_Mass_Storage-0:0 -> ../../sdb
			[root@sprint by-id]#
			</pre>

			* Mount the flash drive to: ''/media/U680_UMSD''.

			<pre>
			[root@sprint by-id]# cd
			[root@sprint ~]# mkdir /media/U680_UMSD
			[root@sprint ~]# mount /dev/sdb /media/U680_UMSD
			[root@sprint ~]#
			</pre>

			* Start the '''sprintpcs''' service:

			<pre>
			[root@sprint ~]# service sprintpcs start
			Starting sprintpcs: U680 ...... [ OK ]
			[root@sprint ~]#
			</pre>

			These extra steps are only required the first time you run the service on the system. The necessary files will be transferred from the flash drive to the: ''/var/lib/sprintpcs'' directory.

While the modem contains a '''GPS''', it appears that the interface to the '''GPS''' device may only be available to Windows.

For some additional information about the modem, I found the [http://www.evdoinfo.com/content/view/2370/64/ Sprint U680 EVDO USB Modem Review] to be very useful.

=== Goals ===

The original goal was to get the '''U680''' working under the '''NST v1.8.1''' development release. However, the first attempts did not yield the desired results. So, it was decided to:

* Install ''Ubuntu'' (which was stated as being compatible with the '''U680''').

* Get it working under '''Ubuntu 8.04''' (as the directions provided with the modem claimed it would work on a ''Ubuntu'' system).

* Get it working under '''Fedora 8''' (using information from the ''Ubuntu'' system).

* Get it working under '''NST v1.8.1''' (using information from the ''Fedora'' system).

=== Ubuntu 8.04 - the Hardy Heron ===

When inserted, the '''U680''' was automatically mounted (like a standard thumb drive). It showed up under the ''/media/U680_UMSD'' directory.

One will find the '''PDF''' manual for the '''U680''' as well as drivers/scripts/etc under the ''/media/U680_UMSD'' directory.

Following the directions provided caused a ''core dump'' under '''Ubuntu'''. Using '''strace''', I was able to determine that the '''./connect''' program was unable to open the file: ''/proc/bus/usb/devices'' (it was not present on my system). After doing some searching on the Internet, I discovered that this file isn't present until the ''usbfs'' is mounted. After mounting the ''usbfs'', the '''U680''' worked as expected.

Quick Summary (what I did to get it working - logged in as ''root''):

* Mount: ''usbfs'' - not required if already mounted (only required if you don't see the: ''/proc/bus/usb/devices'' entry).

<pre>
root@fajita:~# mount -t usbfs usbfs /proc/bus/usb
root@fajita:~#
</pre>

* Insert the '''U680'''.

* Copy the ''/media/U680_UMSD/Linux_Ubuntu'' directory to your hard disk:

<pre>
root@fajita:~# cp -r /media/U680_UMSD/Linux_Ubuntu /root/
root@fajita:~#
</pre>

* Run the '''connect''' command provided:

<pre>
root@fajita:~# cd /root/Linux_Ubuntu
root@fajita:~/Linux_Ubuntu# ./connect

... Lots of output as connection is established ...

</pre>

=== Fedora 8 ===

After getting the '''U680''' working under '''Ubuntu 8.04''', it was then possible to figure out the steps to use the '''U680''' under '''Fedora 8'''.

Quick Summary (what I did to get it working - logged in as ''root''):

* Make sure the '''wvdial''' package is installed.

<pre>
[root@localhost ~]# rpm -q wvdial || yum install wvdial
wvdial-1.60-3.fc8
[root@localhost ~]#
</pre>

* Mount: ''usbfs'' - not required if already mounted (only required if you don't see the: ''/proc/bus/usb/devices'' entry).

<pre>
[root@localhost ~]# mount -t usbfs usbfs /proc/bus/usb
[root@localhost ~]#
</pre>

* Insert the '''U680'''. It should ''auto-mount'' to the ''/media/U680_UMSD'' directory (if not you may need to mount it by hand).

* Copy the ''/media/U680_UMSD/Linux_Ubuntu'' directory to your hard disk:

<pre>
[root@localhost ~]# cp -r /media/U680_UMSD/Linux_Ubuntu /root/
[root@localhost ~]#
</pre>

* Fix the '''execute.sh''' script provided (the '''echo''' statements all need to have the ''-e'' option added so that the contained escape characters are properly printed):

<pre>
[root@localhost ~]# sed -e 's,^echo ,echo -e ,' Linux_Ubuntu/execute.sh
[root@localhost ~]#
</pre>

* Stop the '''NetworkManager''' service if it is running (not sure if this is necessary):

<pre>
[root@localhost ~]# service NetworkManager stop
Stopping NetworkManager daemon: [FAILED]
[root@localhost ~]#
</pre>

* Run the '''connect''' command provided:

<pre>
[root@localhost ~]# cd /root/Linux_Ubuntu
[root@localhost ~]# ./connect

... Lots of output as connection is established ...

</pre>

* At this point the connection should be established, HOWEVER, the file: ''/etc/resolv.conf'' might not be set properly. The '''DNS''' servers should appear near the end of the output of the window running the '''./connect''' command. I was discovered that the: ''resolv.conf'' file was created under: ''/etc/ppp/resolv.conf''. Copying this file to: '''/etc/resolv.conf''' fixed the '''DNS''' issues (made it possible to resolve names to '''IP''' addresses).
