Trouble on Sending a Lot of SMS

[A. Andria]

Dear friends,

Perhaps you can give me an enlightenment. I had finished a sms based 
project. Previously, i am using an old Nokia 5110 and gnokii 0.6.14. 1 
Sms was sent about 8 second. And then, because it takes a while to send 
a sms then we are replacing the old Nokia 5110 with iTegno 3000 GSM 
modem. Finally, 1 sms was sent about 3.6 to 4 second. It means that i 
can send 1000 sms in 1 hour. And this thing had been tested (we can send 
1000 sms in 1 hour).

All the things running well until 1 weeks ago. We have a trouble when 
sending 1400 sms, till the next day still 60% sms was sent, so 40% sms 
are pending. It must all the sms sent in 1.5 hour. I guess that we have 
a trouble when sending a sms with a have a lot of sms. Or may be in that 
day the sms provider traffic is to high volume/traffic. Or may be the 
other things make this problem?

If we are working with gnokii, sometimes after a few minutes gnokii got 
hang-up or the sms can not stored (save to the database) or can not send 
(get from the database and sent it out). So, we must stop the gnokii 
processed daemon and then start it again. But, i think it's a waste time 
if we are always stop and start it again. And the worst thing is we 
didn't know when the gnokii got hang-up. Below is my own bash script to 
handle this situation.

#!/bin/bash

# Check mysql.sock
# ----------------------------------

MYSQL_SOCK_DIR="/opt/lampp/var/mysql";
MYSQL_SOCK_NAME="mysql.sock";

if [ ! -x "$MYSQL_SOCK_DIR/$MYSQL_SOCK_NAME" ]; then

   echo "Can not found $MYSQL_SOCK_NAME in $MYSQL_SOCK_DIR"
   echo "Please check if MySQL Server is running or change the location 
of $MYSQL_SOCK_NAME"
   echo "Exiting..."
  
   exit 1

fi

# ----------------------------------

MYSQL_SOCK_LINK_DIR="/var/run/mysqld";
MYSQL_SOCK_LINK_NAME="mysqld.sock";

if [ ! -x "$MYSQL_SOCK_LINK_DIR/$MYSQL_SOCK_LINK_NAME" ]; then
      
   echo "Can not found $MYSQL_SOCK_LINK_NAME in $MYSQL_SOCK_LINK_DIR"
   echo ""
   echo "Trying to linking $MYSQL_SOCK_DIR/$MYSQL_SOCK_NAME to 
$MYSQL_SOCK_LINK_DIR/$MYSQL_SOCK_LINK_NAME ..."
  
   /bin/ln -s "$MYSQL_SOCK_DIR/$MYSQL_SOCK_NAME" 
"$MYSQL_SOCK_LINK_DIR/$MYSQL_SOCK_LINK_NAME"
  
   if [ ! -x "$MYSQL_SOCK_LINK_DIR/$MYSQL_SOCK_LINK_NAME" ]; then
      
       echo "Failed to linking $MYSQL_SOCK_DIR/$MYSQL_SOCK_NAME to 
$MYSQL_SOCK_LINK_DIR/$MYSQL_SOCK_LINK_NAME"
      
       exit 1

   else
          
       echo "Success to linking $MYSQL_SOCK_DIR/$MYSQL_SOCK_NAME to 
$MYSQL_SOCK_LINK_DIR/$MYSQL_SOCK_LINK_NAME"
  
   fi

fi

# ----------------------------------
# gnokii smsd path
# ----------------------------------
SMSD_PATH="/usr/local"

while true
do
   killall smsd >/dev/null 2>&1
   sleep 3
   $SMSD_PATH/sbin/smsd -u usersms -d sms -c localhost -m mysql 
>/dev/null 2>&1 &
   sleep 1m
done

Sometimes the mysql.sock location is differ from the os/machine to 
other. So, in the script above i tried to find the mysql.sock location. 
If exist ignore it but if not exist create a link one. We need this 
mysql.sock because gnokii didn't work if gnokii didn't find the mysql 
socket. Of course this script useful when we want to combine gnokii with 
MySql database.

To help on troubleshooting the slow moving or failed of sent sms it must 
there a log or script. Yes, we can find the status from the database but 
i think it's nice if we have a file that keep all the log of sent sms. 
But, i didn't find how to do this. I have turn on the debug mode on gnokiirc

Need your help.
