[Howto] Esmtp Email, PHP, Reminder, send_logfile
How to send emails and use php-mail and now perl-mail from your asus:
precondition: installation according wengi's howto. Further an extra email account with any provider. The provider must have a regular mailserver. Please ensure, that all account datas are available.
If you want to use emails with php and/or perl, you need a wengi installation and install your webserver, mysql and php according wpte's howto.
WinSCP, Putty, mc or nano or vi is called editor
Preamble: in this howto we use esmtp. I never had success with sendmail. But esmtp has a aquivalent sendmail syntax, so we can use it for everything.
It is very easy to install and easy to use, even for multiple accounts.
For more informations just google....
INSTALLATION:
Code:
ipkg update
ipkg install esmtp
touch /opt/etc/esmtprc
vi /opt/etc/esmtprc #switch to insert mode
identity accountname@testdomain.com
hostname smtpserver.testdomain.com:25
username "accountname@testdomain.com"
password "accountpassword"
#save the file
cd /tmp/local/root
touch email
vi email #switch to insert mode
date: 29.05.2011
to: anyemailname@domain.com
subject: Test-email
from: accountname@testdomain.com
This is a testmail from the asus router
#save the file
esmtp -t < email
The identity is your new account which you must have.
The hostname must be a valid smtp server of your/any provider.
The username is your accountname (usually your email-name)
Password is your password of you emailaccount.
The used emailaddress (anyemail@domain.com) in file email must be a valid address.
Check that you have received your email
Consider, this way you can send for instance your logfile daily with the help of cron.
Or you can install a simple to use reminder system.
Further, you can use your esmtp-mail as default mailsystem with PHP.
Just to show you, how you can use your mailsystem you will find some script-code for your shell below as well as how to configure PHP and php tests.
Further, you will find now a short introduction of using perl-mail with a perl test page.

A simple to use reminder system
A simple reminder system by mail:
Think about how often you forgot mother's/father's/sister's birthday or your wedding day.
Just set the var accountname to your email account of your asus
Save the script to /opt/bin/reminder and set the rights:
Code:
#! /bin/sh
#Mail a reminder to any recipient with esmtp
#written by newbiefan 2011 for user of asus routers
#contact: hirau@gmx.at
#Please read the entire howto in order to understand everything
#use name of your file, usually reminder.txt - you can store the file anywhere
bfname=/opt/etc/reminder.txt
accountname="youremail@yourprovider.com"
#use your loglocation, usually logs are stored in /opt/var/log
loglocation=/opt/var/log/reminder.log
#if you do not need any log-file, uncomment
#loglocation=/dev/null
#we count all lines
countlines=`/opt/bin/wc -l $bfname | /opt/bin/cut -d " " -f1`
today_long=$(/opt/bin/date +"%d.%m.%Y")
today=$(/opt/bin/date +"%d.%m")
#lets start with line 1
i=0
while [ $i -ne $countlines ] ; do #start the loop over each line
let i=$i+1
#grab data from file
born=`/usr/bin/head -n$i $bfname|/usr/bin/tail -n1|/opt/bin/cut --delimiter=: -f1`
reminddate=`/usr/bin/head -n$i $bfname|/usr/bin/tail -n1|/opt/bin/cut --delimiter=: -f2`
recipient=`/usr/bin/head -n$i $bfname|/usr/bin/tail -n1|/opt/bin/cut --delimiter=: -f3`
subject=`/usr/bin/head -n$i $bfname|/usr/bin/tail -n1|/opt/bin/cut --delimiter=: -f4`
text_to_send=`/usr/bin/head -n$i $bfname|/usr/bin/tail -n1|/opt/bin/cut --delimiter=: -f5`
if [ "$today" = "$reminddate" ] ; then #yes, create the email
echo "date: $today_long" > /tmp/remindmail
echo "to: $recipient" >> /tmp/remindmail
echo "subject: $subject" >> /tmp/remindmail
echo "from: $accountname" >> /tmp/remindmail
echo >> /tmp/remindmail
echo "AUTOMAILER: REMINDER FOR DATE $born" >> /tmp/remindmail
echo $text_to_send >> /tmp/remindmail
echo "Email is automatically generated, please do not answer!" >> /tmp/remindmail
/opt/bin/esmtp -t < /tmp/remindmail # send email
onlytime=`date +"%T"`
echo "Reminder sent $today_long at $onlytime to $recipient with subject: $subject" >> $loglocation
fi
done #end of lines in file
set the rights with chmod 755 /opt/bin/reminder
Further you need a textfile with the data.
Make a file reminder.txt and add your entries. The syntax of a line is following:
date_to_remind:when_to_remind:recipients_email:you rsubject:Text_to send
Consider always to make no spaces and to use as delimiter a : (colon)
The format of date_to_remind must be: dd.mm.yyyy
The format of when_to_remind must be: dd.mm
Recipients email must be a valid email address
Your subject can be any short text
Text_to_send can be any text (should not be too long)
Just add your lines (as much as you want) to you file reminder.txt
Store your reminder.txt to /opt/etc/reminder.txt
Code:
touch /opt/etc/reminder.txt
vi /opt/etc/reminder.txt #goto insert mode
31.03.1960:28.03:hirau@gmx.at:Birthday reminder:Please remember Helmut's birthday
28.06.1936:05.06:hirau@gmx.at:Birthday reminder:Attention, Mama's birthday is coming soon!
28.06.1936:24.06:hirau@gmx.at:Second birthday reminder:Attention, Mama's birthday in 4 days!
28.06.1936:24.06:sistersaccount@gmx.at:Birthday reminder:Attention, Mama's birthday in 4 days!
#save the file
Now only one thing remains, add to your crontab: (If you are not root, use admin instead)
Code:
0 1 * * * root /opt/bin/reminder
No worry any more to forget anything important!
If any problem occurs when using cron, just use the full path of each command (e.g.: /usr/bin/head a.s.o.)
Thats it - have fun.
EDIT:In order to save your valuable time, I've added the full path to some command, hence it will work propper with cron
esmtp with php configuration
Howto configure php to use esmtp:
This is simple and fast, just open with any editor (winscp) your /opt/etc/php.ini file
and change line 588:
Code:
; For Unix only. You may supply arguments as well (default: "sendmail -t -i").
sendmail_path = /opt/bin/esmtp -t -i
In order to test your php-mail, store the file below to (for instance) /opt/www/cgi-bin/mailnow.php
Please change your Asus-Email account and the recipient in the file below.
Code:
<HTML>
<HEAD>
<title> Mailnow </title>
</HEAD>
<BODY>
<?php
$from_header = "From: your@mailaccount.com";
$to = "recipient@domain.com";
$subject = "Your first Testmail";
$message = "This is your first Email from your Webserver using PHP!";
mail( $to, $subject, $message, $from_header )
?>
<p align="center">
<h1>Test-email</h1><br>
is sent to your account. Everything seems to work proper</br>
<p>
</BODY></HTML>
Now call your page with http://ip.of.your.asus/cgi-bin/mailnow.php
When you can see a page with Test-email, everything is ok.
And I'm really sorry - I'm not good in PHP-coding - but it works.
Have fun
PHP 404-error-page with email function
Or you can use a own 404 error page withh mailfunction for your webserver:
Save the file into the root-directory of your webserver (/opt/share/www/error-page404.php
I found the PHP code elsewhere in the internet and can not find it again, so credit to unknown.....
Change the accountname and recipient.
Code:
<HTML>
<HEAD>
<title> 404 Error Page</title>
</HEAD>
<BODY>
<p align="center">
<h1>Error 404</h1><br>Page Not Found
<p>
<?php
$ip = getenv ("REMOTE_ADDR");
$requri = getenv ("REQUEST_URI");
$servname = getenv ("SERVER_NAME");
$combine = $ip . " tried to load a missing" . " page on webserver" . $requri ;
$httpref = getenv ("HTTP_REFERER");
$httpagent = getenv ("HTTP_USER_AGENT");
$today = date("D M j Y g:i:s a T");
$note = "We apologize for any inconvenience, Email is sent to administrator" ;
$message = "$today \n
<br>
$combine <br> \n
User Agent = $httpagent \n
<h2> $note </h2>\n
<br> $httpref ";
$message2 = "$today \n
$combine \n
User Agent = $httpagent \n
$note \n
$httpref ";
echo $message;
$from_header = "From: accountname@testdomain.com\r\n";
$to = "recipient@domain.com";
$subject = "404 Error";
$today = date("D M j Y g:i:s a T");
$ip = getenv ("REMOTE_ADDR");
$requri = getenv ("REQUEST_URI");
$servname = getenv ("SERVER_NAME");
$pageload = $ip . " tried to load http://" . $servname . $requri ;
$httpagent = getenv ("HTTP_USER_AGENT");
$httpref = getenv ("HTTP_REFERER");
$message = "$today \n\n$pageload \n\nUser Agent = $httpagent \n\n$httpref ";
mail( $to, $subject, $message, $from_header );
?>
</BODY></HTML>
Then you have to change your lighttpd.conf in /opt/etc/lighttpd.conf and change the line
Code:
## error-handler for status 404
#server.error-handler-404 = "/error-handler.html"
server.error-handler-404 = "/error-page404.php" #use the name of your error page
after restart of lighttpd you get an email when a missing page is called
Test it with your browser:
Code:
http://ip.of.your.asus/notexistingpage
You should see now your 404-error-page and get an email.

howto use perl-mail with lighttpd
Well, provided you have installed perl and some other perl-modules you can use perl-mail and mysql.
First, ensure you have installed this from optware repo:
Code:
ipkg list_installed |grep perl
should give you the following output:
Code:
perl - 5.8.8-23 - Practical Extraction and Report Language.
perl-carp-clan - 5.3-1 - This module reports errors from the perspective of the caller of a clan of modules, similar to Carp.pm itself.
perl-date-calc - 5.4-2 - Gregorian calendar date calculations.
perl-date-manip - 5.48-1 - date manipulation routines
perl-dbd-mysql - 4.006-1 - DBD-mysql - The Perl Database Driver for MySQL.
perl-dbi - 1.607-1 - DBI - The Perl Database Interface by Tim Bunce.
Then you are fine, now lets adjust your lighttpd.conf
Activate the mod cgi:
and after section index-file.names insert this:
Code:
#tell lighty howto handle cgi
$HTTP["url"] =~ "/cgi-bin/" {
cgi.assign = ( ".pl" => "/opt/bin/perl",
".cgi" => "/opt/bin/bash",
".sh" => "/bin/sh" )
}
In case you do not need to assign bash and shell, just set extension .cgi to perl. Then your cgi.assign should look like this:
Code:
#tell lighty howto handle cgi
$HTTP["url"] =~ "/cgi-bin/" {
cgi.assign = ( ".pl" => "/opt/bin/perl",
".cgi" => "/opt/bin/perl" )
}
With the first cgi.assign example you can install this webinterface for your optware installations. Please consider anytime the security risks. If you do not know what you are doing including related consequences, please install just the second example of cgi.assign.
Well now the perl-testpage, store it to folder cgi-bin/mailnow.pl of your webservers document root.
Just set the vars to and from to your needs.
Code:
#!/opt/bin/perl
print "Content-type: text/html\n\n";
$title='Perl Mail Test for Asusrouters';
$to='recipient@domain.net';
$from= 'yourasusaccount@yourdomain.com';
$subject='Perl Mail Test';
open(MAIL, "|/opt/bin/esmtp -t");
## Create Header, Message and send everything, consider after subject \n\n - it's an emty line
print MAIL "To: $to\n";
print MAIL "From: $from\n";
print MAIL "Subject: $subject\n\n";
## Mail Message
print MAIL "This is your first Perl Message from your Asus or any other machine\n";
print MAIL "When you are able to read this message, your Perl including cgi-bin works!\n";
print MAIL "This example is taken from: http://www.cyberciti.biz/faq/sending-mail-with-perl-mail-script/\n";
print MAIL "and adapted by user newbiefan for asusrouter.\n";
close(MAIL);
print "<html><head><title>$title</title></head>\n<body>\n\n";
## HTML content sent, let us know we have sent an email
print "
<h1>$title</h1>
An Email has been sent from $from to $to
</body></html>";
Consider to set the rights to 755.
Have fun
