SMTP script + Redhat ES 4

Chrizzieej · 06-09-2008, 02:24 AM

Hello,

I've got a perfectly running SMTP script under Redhat ES 3, but when I run it under Redhat ES 4 it doesn't work any more. Messages have got strange characters or messages are not being send at all. I don't know what the problem is, is there anyone who can tell me what the problem might be?

This is my script:

Code:

#!/bin/sh
host=****
port=25
nummer=$1
tekst=$2
    
( echo open ${host} ${port}
sleep 1
echo "HELO ****"
sleep 1
echo "MAIL FROM: ****"
sleep 1
echo "RCPT TO: ****"
sleep 1
echo "DATA"
sleep 1
echo -e "\nSUBJECT: ****\n\nCallerID=9991\nPASSWORD=9991\nSMS=$nummer\nTEXT=$tekst"
sleep 1
echo "."
sleep 1
echo "QUIT"
sleep 1
) | telnet

I've replaced IP-adresses, passwords etc. by **** offcourse

The script is run through sms.sh <telnr> <message>.

Many thanks,

Greetz Chris

Script doesn't look "weird". What are the exact error lines you get back in the mail or on screen?

When the script runs 4 times after each other, only the first message has been received. And sometimes characters have been replaced by questionmarks (?). It's very weird!

Whose mailserver are you using? Your own? Your ISPs? Other MTAs? Since you didn't post any exact errors or anything else to go on, about the timing, if you're not using your own MTA, try adding a sleep of say 30 seconds after each send, then decrease until you hit the threshold. Wrt the chars, comparing your input with output should show where it fails. If that's all too generic for you please post the exact error messages you receive from the MTA along with some examples from your comparison.

I don't get any errors from the MTA, the strange characters only exist in the textmessage we receive on our mobile phone. This script sends a SMTP flux to our VOIP/SMS gateway. Under Redhat3 this works perfect, under Redhat4 it doesn't. I allready build in a sleep 60, then the problem with not receiving al messages is solved, but i'm still getting some change characters while the send message doesn't.

Do the "strange characters" also occur when you receive the message as email? Any word on the comparison part?

Chrizzieej · 06-09-2008, 08:00 AM

Nope, I also redirected the output to a text-file which is allright so there's really nothing wrong with the output or send message! But why doesn't it work right under Redhat4 :S

OK. I know you're interested to find out but you have to realise responses like "nope" (did or didn't you check receiving as email?) "nothing wrong" (on which different machines and in what ways did you check?) or "doesn't work" don't give me much to go on. So. What parts of $TEXT show "strange characters"? Separate characters, whole words, words with certain characters? Where does the text originate (log watcher, monitoring application, database)? Can you compare locale on both machines (type 'locale', save to tempfile, then diff). What happens if you convert ('man iconv') the $TEXT to 7-bit something vaguely resembling The GSM 03.38 Default Character Set (see for http://www.gammu.org/wiki/index.php?...Set_Conversion or http://smstools.meinemullemaus.de/GS...cification.pdf) or force the charset used on the RHEL-3 machine?

When I send this message:

Test -> Pas op, Er zijn problemen. Was 34, Nu 36. Graag actie!!!!

Redhat 3 ES sends it perfectly, Redhat 4 ES sends it as:

Test -> Pas op, Er zijn problemen. Was ??????. Graag actie!!!!

Both machine have en_US.UTF-8 as default charset.

ps. Sorry it's a Dutch textmessage

Great! That covers two out of four questions.
