gsm modem stopped working in zabbix 2.4.5

[petr11]

Hi

I've just update from zabbix 1.8.13 to 2.4.5 and zabbix can't communicate with modem now. In all previous z. versions it was ok for many years ago.

My modem: Siemens MC35i
/dev/ttyUSB0 (permissions 666)

sms test with gnokii OK (works only with baud 9600; bigger 19200 or 115200 doesn't)

Zabbix actions info: I saw these three...
Expected [OK] received [+C]
Expected [OK] received [K]
Expected [OK] received [O]

stty -F /dev/ttyUSB0 --all
speed 9600 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z;
rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0;

Hi

Have you solved your problema?

I'm dealing with this too.
Same sms hardware, same port /dev/ttyUSB0

I've istalled zabbix 2.2.10, 2.4.5 and 2.4.6 in Oracle 6.5, 6.6, 6.7, 7.0 and 7.1 and sms's do not work, with same result
Expected [OK] received [+C]
Expected [OK] received [K]
Expected [OK] received [O]
and one more
Expected [OK] received []

But if I install smstools I can send na sms without problems.

What is the last version that works for you?

Best Regards,

[petr11]

Hi

didn't solve . I needed sms alerts working urgently. So I did an external script as a workaround.

Just simple shell script which send sms using any other sw you like, ex.:
echo "$3" | gnokii --sendsms $1 > /dev/null

Use this script in zabbix media.

Not clear, but solution. I would be happy if anyone can help to get working zabbix->gsm back again

gsm modem stopped working in zabbix 2.4.5

Hi again

After some struggler I manage to send sms's.

I've concentrate my efforts in Oracle Linux 6.7.
Fresh install with version 2.4.2 of Zabbix send sms's. Upgrade to version 2.4.6 stop sending sms's.
Fresh install with version 2.4.3 of Zabbix send sms's. Upgrade to version 2.4.5 stop sendinf sms's.
Fresh install with version 2.4.4 of Zabbix send sms's. Upgrade to version 2.4.5 or 2.4.6 cannot send sms's.

So, the last version that permits sending of sms's is version 2.4.4.

Best Regards
