Hello,
I was looking for this feature, but I didn't find it. I'm using SMSTools in our NMS to send sms alerts. Everything works great, but I can't send the same alert to many persons - at this moment I'm making new sms for every one..The question is:what should the message form look like to be send to many numbers?Below there are some examples which I tried, but without success:

1)
To: 48600700800; 48600700801

SMSmessage

2)
To: 48600700800
To: 48600700801

SMSmessage

3)
To: 48600700800 48600700801

SMSmessage

Thanks in advance for any help in this topic.

For smsd every SMS is a single file. This is because sending to some numbers may fail, delivery timestamps are stored to files, etc...

You can use checkhandler to check "To:" field(s) and create multiple files if necessary. Here is an example: Multiple recipients in single SMS file.

I just edited the sample. It now allows multiple numbers in single To: field, and also multiple To: fields. Semicolon also works, but do not use it.

Sorry for bothering You about something that was already solved before Keke :]

But I'm having some problems with using this script:
My smsd.conf:


Your sample script /etc/multisms.conf:
#!/bin/bash

# Sample script to allow multiple recipients in one message file.
# Define this script as a checkhandler.

outgoing="/var/spool/sms/outgoing"

recipients=`formail -zx "To:" < "$1"`

#count=`echo "$recipients" | wc -l`
count=`echo "$recipients" | wc -w`
if [ $count -gt 1 ]; then

  # Will need echo which accepts -n argument:
  ECHO=echo
  case `uname` in
    SunOS)
      ECHO=/usr/ucb/echo
      ;;
  esac

  messagebody=`sed -e '1,/^$/ d' < "$1"`
  headers=`formail -X "" -I "To:" -f < "$1"`

  for recipient in $recipients
  do
    file=`mktemp $outgoing/send_XXXXXX`
    $ECHO "To: $recipient" > $file
    if [ "x$headers" != "x" ]; then
      $ECHO "$headers" >> $file
    fi
    $ECHO "" >> $file
    $ECHO -n "$messagebody" >> $file
  done

  # Remove processed file:
  rm $1

  # Tell to smsd that checkhandler has spooled this message:
  exit 2
fi

exit 0

Of course Keke - I've noticed this after I post my reply ;)
One more thing: your script generates random temp file names:


Is there a chance to stay with original names with only tiny changes for example: originalnameofsms_1,2,3?
In our case the name of the sms is the name of event and it's quite needed for troubleshooting..

Thanks,
Peter

The script can do anything what is required... ;)

Comment out the line containing mktemp and add those three lines. This will keep the original name and add _1, _2 and so on:

  do
    #file=`mktemp $outgoing/send_XXXXXX`
    [ -z $nr ] && nr=1
    file="$1_$nr"
    nr=$(($nr + 1))

Perhaps a phone number also can be used. /var/spool/sms/outgoing/eventname_phonenumber:

  do
    #file=`mktemp $outgoing/send_XXXXXX`
    file="$1_$recipient"

Also note that you can use your own headers in the SMS file, if they do not override existing headers in smsd (fileformat). This will add a  "Event:"  header to the file and later all details can be read from file:

  tmp=$(readlink -f $1)
  event=${tmp##*/}

  for recipient in $recipients
  do
    #file=`mktemp $outgoing/send_XXXXXX`
    [ -z $nr ] && nr=1
    file="$1_$nr"
    nr=$(($nr + 1))

    $ECHO "To: $recipient" > $file
    if [ "x$headers" != "x" ]; then
      $ECHO "$headers" >> $file
    fi
    $ECHO "Event: $event" >> $file
    $ECHO "" >> $file
    $ECHO -n "$messagebody" >> $file
  done
