| We use:
| /usr/ports/net-mgmt/nagios
| /usr/ports/mail/exim
| /usr/ports/comms/gammu
|
| Nagios is used to lookup on host and services. When a problem occures,
| it sends a letter to address <user-sms>@domain. Exim has router:
| sms_posting:
| transport = mail2sms
| driver = manualroute
| local_part_suffix = -sms
| route_list = *
|
| ...and transport:
| mail2sms:
| driver = pipe
| user = mailnull
| command = /usr/local/bin/mail2sms.py
|
| The last script is at the attachement. It uses a Subject field as a
| text to send via sms and write an outgoing message to
| /var/spool/sms/outbox. Gammu smsd daemon is scanning this directory
| for any existing files and send them via GSM phone. This phone is
| connected to our server via COM or USB port (Prolific Technology chip
| USB-to-COM cable for the latter).
|
| /var/spool/sms/db/phones is the file with lines
| <target-phone-number>\tab<user-sms@domain>:
| +7495NNNNNNN bsam-sms@domain.ru
|
| We have been using this technology for a year and don't have any

Hi Boris,
This is great!!! After looking at the Nagios contacts, I believe this
solution is almost akin to K.I.S.S.
However, e-mail being e-mail, I thought about spammers, but that looks
like something I can take care of within Exim using some rules to ensure
that only valid senders can get mail into the SMS...
I have two concerns:
(1). Your router's route_list line seems incomplete to me, no?
(2). Assuming SMSes are charged, how do you monitor the charges?
(phone must have credit in order to send SMS, no?)
(3). Suppose someone sent a reply to the system, where does it go?
(4). You mention that mail2sms.py "uses a Subject field as a text to
send via sms and write an outgoing message to /var/spool/sms/outbox...."
It is still not yet clear to me where the "Subject field" comes
from.
Thank you so much for making public this solution!
