CentOS - Feb 2009 - OT: Suggestions for connecting a postfix to an sms box

Hi there,
I would like to hear some hardware recomendations to connect our smtp
server (postfix) to an external SMS box.
Basically I am looking for a SMS box that takes messages via smtp and
sends them via the SMS part.
Has anyone here implemented a solution like this?
I must use an in house sms box (GSM), I cannot use a service provider
(such as internet smtp to sms providers).

thanks,

I think we (well, my co-worker) built such a thing here (with kannel).
It will directly talk to the SMS-center at the carrier.

If you can buy them, I suspect that they are very pricey.
;-)

Also, you will of course also need a large-account at your carrier,  
which will also cost a certain fee.

One of our neighbors down the street is an Electronic Engineer for one
of the Colombian cell phone operators. They began converting from CDMA
to GSM several years ago. If you end up needing a Consultant, for any
GSM stuff you are involved with, contact me off list and I will put
you in touch with him. Cali is one hour from Panama City, on COPA,
etc.

I love this list! Paragraph mode REALLY cleans things up. Although it worked,
this makes my first attempt look really amateurish.
Be sure to put the definition of $/ inside a code block { } if you are using it
inside a program or it will cause difficulties in other areas since it is
defined in main and therefore used everywhere.

#! /usr/bin/perl -w
use strict;

# use this like ./p2 < in.txt > out.txt
# or cat file | ./p2 > out.txt

{
   local $/ = ''''; # turn on paragraph mode
   while (<>) {
      if (/localhost/) {
         $_ =~ s/\/\*//;
         $_ =~ s/\*\///;
      }
      print "$_\n";
   }
}

A tad simpler:

#! /usr/bin/perl -w
use strict;

my $file;

open FILE, "stuff.txt" or die;

# Undefine the input record separator.

undef $/;

# Slurp the whole file in

$file = <FILE>;
close FILE;

# Pattern match on the stanza we want to uncomment and uncomment it.  
You may need to play with
# the white space in the output to get the formatting you want.

$file =~ s?/*\s*udp_send_channel {\n\s*host=localhost\n\s*port = 
10017\n\s*ttl = 1\n\s*} */\n?udp_send_channel {\n  host=localhost\n  
port = 10017\n  ttl = 1\n}?;

# Write the result.

print $file;

#~~~~~~~~~~~~~~~~~End of Script~~~~~~~~~~~~~~

Dave
