Using kannel for sending SMS

[GarySober]

I am having Fedora operating system installed on my desktop which belongs to the Linux family. I have downloaded and installed kannel on my system for sending messages. I have also configured kannel successfully. When I want to send messages I am not able to send it. Is there any installation problem with kannel? Also give me the installation and configuration steps so that I can fix the problem.

Kannel is software used for sending and receiving messages. The steps for downloading and installation of kannel are given below:
The kannel software is very easy to download and compile. For downloading you need to visit the website and download gateway-1.X.Y.tar.gz file.
The command for downloading is given below

# mkdir src
# cd src
# tar xfz ../downloads/gateway-1.4.1.tar.gz
# cd gateway-1.4.1
# configure --prefix=/usr/local/kannel

Now install the kannel to the /usr/local/kannel folder.
The code for compiling and installing is given below

# make
# sudo make install
password: **************

If you have set the password for your system then you need to enter it for installing. The installation of kannel will start.

After performing the installation of kannel software you need to set up the configuration files. This file is having a zillion options to support kannel in all the possible ways and methods. The simple smskannel.conf file in the gw/ directory has all the basic information we want. The configuration is divided into several parts including server that handle sending and receiving of SMS and system that handles final dispatching of scripts.

The configuration for “Core” group is given below:
group = core
admin-port = 13000
smsbox-port = 13001
admin-password = bar
#log-file = "/tmp/kannel.log"
#log-level = 0
box-deny-ip = "*.*.*.*"
box-allow-ip = "127.0.0.1"

The configuration for smsc is given below
group = smsc
smsc = at
modemtype = auto
device=/dev/ttyS0
my-number = 123123123123
connect-allow-ip = 127.0.0.1
log-level = 0

Steps to send messages via kannel are very simple. We can also send messages via HTTP interface whereas you can send messages in PHP5 by using the iconv function. The code to send messages using kannel is given below:

function sendSmsMessage($in_phoneNumber, $in_msg)
{
$url = '/cgi-bin/sendsms?username=' . CONFIG_KANNEL_USER_NAME
. '&password=' . CONFIG_KANNEL_PASSWORD
. '&charset=UCS-2&coding=2'
. "&to={$in_phoneNumber}"
. '&text=' . urlencode(iconv('utf-8', 'ucs-2', $in_msg));

$results = file('http://'
. CONFIG_KANNEL_HOST . ':'
. CONFIG_KANNEL_PORT . $url);
}

You need to set allow_url_fopen to on in order to send message.

The above solutions works fine and I have downloaded and installed kannel on my system. After successfully configuring the kannel I am facing the problem. The messages are not send it is blocked by the PHP scripts coming from the internet. Is there any way to stop the PHP scripts so that it doesn’t block the messages?

When successfully installing kannel on the system the server listens to a particular ports. On that port the request is send. So if you want to send SMS you can send it by making use of the PHP script using the fopen command. It will connect to a particular port which is specified in the code. The code of fopen command is given below:

#!/usr/bin/php -q
<?php
 
$fd = fopen("php://stdin", "r");
$email = "";
while (!feof($fd))
{
	$email .= fread($fd, 1024);
}
fclose($fd);
mail('you@yoursite.com','From my email pipe!','"' . $email . '"');
?>
