Inside the file /etc/default/smstools there is a line: USER="smsd". Change that line.

For example after editing the file has a content:
# smsd default file

# Defines under which user smsd is running. This may need to be changed
# if using devices other then /dev/ttyS0
USER="root"
GROUP="dialout"

# Specifies pathes.
PIDFILE="/var/run/smstools/smsd.pid"
INFOFILE="/var/run/smstools/smsd.working"

First ensure that smsd is not running. Disconnect the modem, and connect it back. Use dmsg to see what ports are created. If there is nothing to see, wait a moment and use dmesg again. There should be three ports seen, and the first one should be used.

Instead of using the first port directly, use a link for it. Check which links are available:
ls -ltr /dev/serial/by-id/

There may be something like this:
usb-HUAWEI_HUAWEI_Mobile-if00-port0 -> ../../ttyUSB0

Check which link points to the first ttyUSB port, and use that link, like:

[GSM1]
device = /dev/serial/by-id/usb-HUAWEI_HUAWEI_Mobile-if00-port0


When a modem disconnects and is connected back again, sometimes the ttyUSB port is not the same as before. /dev/serial/by-id/xxx link remains the same, so it's better to use it.

You should copy the name of the symlink from your system, not from my post which was just an example.

smsgina wrote
lrwxrwxrwx 1 root root 13 Mär 9 16:35 usb-HUAWEI_HUAWEI_Mobile-if00-port0 -> ../../ttyUSB0

Assuming that this was copy-pasted from you system, your setting should be:
device = /dev/serial/by-id/usb-HUAWEI_HUAWEI_Mobile-if00-port0

Notice that ... Mobile <minus> if00 ... (I colorized it, and also fixed the lines in my post, because some another may later use that example and get the same error).

I have to say that I do not understand what is going on now. :shock: Settings looks good, and the symlink exists. Still you get "No such file or directory". I assume that you did not remove the modem after listing those symlinks.

I tested this issue with raspberry pi3 running raspbian-jessie and smsd 3.1.15 installed from repository. Everything works like a charm, with privileges of root or smsd, and with symlink or direct path to ttyUSB0. Strange? :roll:

Next you could go back to the start point. Restore USER="smsd" to /etc/default/smstools, and in the configuration use /dev/ttyUSB0. Then everything should work, as worked before changes were made.

When running smsd as smsd:dialout, eventhandler cannot contain commands which require root privileges. This was the initial problem. For those commands, at least reboot and shutdown, create an external script which is polled by the cron job. Something like: when a cron job sees the script, it is executed. Or even better, write the command to the "flag file", and when cron job reads that file, it can verify that the command is acceptable, and then executes it. Thus, in principle, there are many ways of implementation.

Hope you did not get too confused... ;)

hello keke,

i did a new system setup and the reboot or shutdown option are ok.
after that i changed the original script.

#!/bin/bash
PASSWORD="XYZ"

if [ "$1" = "RECEIVED" ]; then

    TEXT=`sed -e '1,/^$/ d' < $2`
    # Make text uppercase:
    TEXT=`echo "$TEXT" | tr "a-z" "A-Z"`

    RCVPASS=`echo "$TEXT" | cut -d" " -f1`
    ACTION=`echo "$TEXT" | cut -d" " -f2`

    if [ "$PASSWORD" = "$RCVPASS" ]; then
        case $ACTION in

            #Reboot Server
            REBOOT)
                reboot
            ;;

            #Shutdown Server
            SHUTDOWN)
                shutdown -h now
            ;;

            #Interface ppp0 up
            IFUP)
                ifup ppp0            
            ;;

            #Interface ppp0 down
            IFDOWN)
                ifdown ppp0
            ;;  

        esac
    fi
fi

Smsd itself does not use the network. If you have some external network interface to create outgoing files, it of course does not work if the network is down. For local spooling of messages it makes no difference if network is up or not.

Sorry , but i looks like that can not describe the problem.
In this eventhandler - script are 4 ACTION

REBOOT
SHUTDOWN
IFUP
IFDOWN

Sending SMS with ACTION REBOOT or SHUTDOWN or IFUP the related ACTION will execute.

Sending SMS IFDOWN nothing happend and the SMS will not be shoen in the incomming folder.

So you send XYZ IFUP, and it works. And when you send XYZ IFDOWN, the SMS is never received? :shock: If you are completely sure that the SMS was sent to the correct number, and it really is not received, then you should contact your operator. They perhaps have some "badword blocking list" in use, and SMS containing a word IFDOWN is not delivered. :roll:

Does it help if you disconnect and reconnect the modem, so it gets hardware reset?

If you still cannot receive any messages, test the SIM with a handset to see how it works.

If the problem still exists, please contact your network operator, or at least test with a new SIM.

I got the solution.

The command ifup ppp0 builds a connection via the interface ppp0.
Now the modem is occupied and no further action possible.

Thanks for your help and perseverance.
