cron examples

¬†Following commands are made for reference purposes only … zaib


To add scheduled job in linux/ubuntu, use

crontab -e

To view installed cron

crontab -l

Examples:

Run Script after every 5 seconds [Updated 8th Aug, 2016]

I had a UPS monitor script that should run after every 5 seconds to poll the KE input voltage / battery remaining time etc. but as we know that with CRON we can configure interval of minimum 1 minute or above, we cannot set time in seconds. so I make following workaround.

conrtab -e

and added script as follows

# UPMON.SH is my script to monitor UPS
# 10.0.0.1 is my UPS network card
* * * * * /temp/upsmon.sh 10.0.0.1
* * * * * sleep 5; /temp/kemon.sh 10.0.0.1
* * * * * sleep 10; /temp/kemon.sh 10.0.0.1
* * * * * sleep 15; /temp/kemon.sh 10.0.0.1
* * * * * sleep 20; /temp/kemon.sh 10.0.0.1
* * * * * sleep 25; /temp/kemon.sh 10.0.0.1
* * * * * sleep 30; /temp/kemon.sh 10.0.0.1
* * * * * sleep 35; /temp/kemon.sh 10.0.0.1
* * * * * sleep 40; /temp/kemon.sh 10.0.0.1
* * * * * sleep 45; /temp/kemon.sh 10.0.0.1
* * * * * sleep 55; /temp/kemon.sh 10.0.0.1
* * * * * sleep 60; /temp/kemon.sh 10.0.0.1

this way the script will run and wait for five seconds before next execution. ūüôā lalalala / zaib


Run Script after every 2 hours (daily basis* it helped me very much)

0 */2 * * * /temp/script.sh

Run Script at Every 1st day of Month [Every Month]

@monthly /temp/script.sh


Run Script on 1-am on every Monday

0 1 * * MON /temp/xdrive_noupdate.sh


Run Script Daily at 00:00 hours (midnight)

@daily /temp/script.sh

Run Script Daily at 09:00 hours (Morning 9am)

# m h dom mon dow command
00 09 * * * /temp/fullbackup.sh


Run Script every hour 

@hourly /temp/script.sh


Run Script every minute

* * * * * /temp/script.sh


Run Script after every 5 minutes

*/5 * * * * /temp/script.sh


Run Script on Specific Timings And Date of Months, Example run script on 10am and 11am  on 12th of every month.

00 10,11 12 * * /temp/script.sh


Run Script on Specific Hours of Every Month, Example run script on 9am of every month.

00 9 10 * * /temp/script.sh


Run Script on Specific Hours RANGES , Example run script on 10am to 8pm , means every hour from 10am-8pm

00 10-20 * * * /temp/script.sh


Shortcuts in CRON

         
@reboot        Run once, at startup.
@yearly        Run once a year, "0 0 1 1 *".
@annually      (same as @yearly)

@hourly        Run once an hour, "0 * * * *".


Scheduled CON Job running but not producing results …

[Monday 27th Feb,2017]

I scheduled few scripts on my Ubuntu 14.x box that queries remote servers for storage and send customized reports via email. I can see its execution in /var/log/syslog but the script was not able to query the remote win server.

To solve it I had to add the PATH command in the script , sample as below…

#!/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

This solved my issue ūüôā

These are little things that you learn on daily basis ,

One very useful crontab demonstration to check errors or make cron

https://crontab.guru/


Run script after X minute (just one time only, without using cron)

echo YOUR-SCIPT.SH | at now + 1 minute

Sending Email/SMS Alert to User for Service Change Event

Filed under: Radius Manager — Tags: — Syed Jahanzaib / Pinochio~:) @ 12:58 PM

srvchange

 

Screenshot_2016-06-13-12-56-48

SMS Alert


Reference Notes:

Requirements:

We want to send email/sms alert to user about his service package change with old/new package name details. Although this function is builtin in RM , but with customized scripts we can do other functions as well.


Solution:

We will create mysql trigger that will be executed every time srvid column will be changed in rm_users table. then we will create mysql table which will hold all these info. Then the trigger will add user info like old service id , new service id, user name, mobile etc in this table upon srvid change.

Neat & clean.


 

First create mySQL trigger which will be executed once there will be changes made in srvid column in rm_users table.

1- mySQL Trigger

Create file name srvchangetriggers.sql and paste following data

-- MySQL dump 10.13 Distrib 5.5.46, for debian-linux-gnu (i686)
-- Host: localhost Database: radius
-- Syed Jahanzaib
-- ------------------------------------------------------
-- Server version 5.5.46-0ubuntu0.12.04.2-log
DELIMITER ;;
/*!50003 CREATE*/ /*!50017 DEFINER=`root`@`localhost`*/ /*!50003 TRIGGER `myTrigger` BEFORE UPDATE ON `rm_users`
FOR EACH ROW BEGIN
IF NEW.srvid <> OLD.srvid THEN
INSERT INTO rm_usersrvchangehistory (datetime, username, newsrvid, oldsrvid, firstname, lastname, mobile) VALUES (NOW(), new.username, new.srvid, old.srvid, new.firstname, new.lastname, new.mobile);
END IF;
END */;;
DELIMITER ;
-- Dumping routines for database 'radius'
--

2- mySQL Table

Add mySQL table where records will be saved.

Create file name rmsrvchangetable.sql and paste following date

-- phpMyAdmin SQL Dump
-- version 3.4.10.1deb1
-- http://www.phpmyadmin.net
-- Syed Jahanzaib
-- Host: localhost
-- Generation Time: Jun 13, 2016 at 10:32 AM
-- Server version: 5.5.46
-- PHP Version: 5.3.10-1ubuntu3.21
SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";
SET time_zone = "+00:00";
/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;
--
-- Database: `radius`
--
-- --------------------------------------------------------
--
-- Table structure for table `rm_usersrvchangehistory`
--
CREATE TABLE IF NOT EXISTS `rm_usersrvchangehistory` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`datetime` datetime NOT NULL,
`username` varchar(64) NOT NULL,
`newsrvid` varchar(64) NOT NULL,
`oldsrvid` varchar(64) NOT NULL,
`firstname` varchar(64) NOT NULL,
`lastname` varchar(64) NOT NULL,
`mobile` varchar(64) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=63 ;
--
-- Dumping data for table `rm_usersrvchangehistory`
--
/*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */;
/*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */;
/*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */;

Importing the .sql files in Radius DB / mySQL

Now import both files  in radius DB by command

mysql -uroot -pSQLPASS radius < rmsrvchangetable.sql
mysql -uroot -pSQLPASS radius < srvchangetriggers.sql

Test The Changes …

Now try to change any user service, and check rm_usersrvchangehistory by following command

root@ubuntu:/temp# mysql -u root -pSQLPASS -e "use radius; select * from rm_usersrvchangehistory;"
+----+---------------------+----------+----------+----------+-----------+-----------+-------------+
| id | datetime | username | newsrvid | oldsrvid | firstname | lastname | mobile |
+----+---------------------+----------+----------+----------+-----------+-----------+-------------+

+----+---------------------+----------+----------+----------+-----------+-----------+-------------+

Script to fetch data on scheduled basis and SMS/EMAIL…

Create a script that will be scheduled to run after every 5 minutes , it will check in table rm_usersrvchangehistory and will send sms to user about package change event.

mkdir /temp && cd /temp
touch /temp/srvchange.sh
chmod +x temp/srvchange.sh
nano temp/srvchange.sh

and paste following data…

the Script:

 

#!/bin/bash
# srvchange.sh
# Bash script which will run after every 5 minutes and will fetch info from mysqltable
# and will send SMS/Email alert for service change event.

OLDPKGNAME=`mysql -u$SQLUSER -p$SQLPASS -e "use radius; SELECT srvname FROM radius.rm_services WHERE rm_services.srvid = '$oldsrvid';" |awk 'FNR == 2'`
NEWPKGNAME=`mysql -u$SQLUSER -p$SQLPASS -e "use radius; SELECT srvname FROM radius.rm_services WHERE rm_services.srvid = '$newsrvid';" |awk 'FNR == 2'`

# Print FINAL Fetched info
echo "Dear $firstname $lastname ,
Your internet package against your User ID: $username has been upgraded from $OLDPKGNAME to $NEWPKGNAME !

$COMPANY"

# Store Info for sending SMS in /tmp folder where we will call kannel to send customized SMS
echo "Dear $firstname $lastname ,
Your internet package against your User ID: $username has been upgraded from $OLDPKGNAME to $NEWPKGNAME !

$COMPANY" > /tmp/$username.srvchange.sms

# send sms using kannel gateway
curl "http://$KHOST/cgi-bin/sendsms?username=$KID&password=$KPASS&to=$mobile" -G --data-urlencode text@/tmp/$username.srvchange.sms

# If you send lot of SMS via local mobile SIM, then make sure you give enough delay so that your SIM may not get blocked by BULK SMS monitor by TELCOM authority like PTA.
#sleep 15
done
# once done, we should delete the .sms files to clear the garbage
rm -fr /tmp/*.sms


End Results !

Now execute the Script  and witness the Fun !

KANNEL not responding problem occasionally or after modem reset

Filed under: Linux Related — Tags: , , — Syed Jahanzaib / Pinochio~:) @ 10:22 AM

kannellogo


Scenario:

We have Ubuntu 12.x installed and serial modem is attached (Teltonika G10). Kannel is installed and serving as SMS gateway.

Problem:

Sometimes modem stops responding and when we restart the modem, kannel starts giving error of Routing Failed. After restart of KANNEL service, the kannel starts responding to sms request and works fine.

Requirement:

This little issue can be really annoyed if you are doing remote administration OR if sms alerts are important for you to keep informed about various aspects of the network. We want some automatic mechanism that can detect this specific error and then act accordingly.

Example …

  • If KANNEL service is down , try to start it
  • If failed to start the service, then print error, and sends email about incident, (one email per incident), and exit script
  • If service starts successfully, then print info, and sends email about successful attempt.¬†(one email per incident), and continue further
  • Test Kannel log last entries, and look for word Routing failed, if found, then restart kannel service and email.¬†(one email per incident).
  • If it does not found any entry in LOG for specific word, then Print OK Result for all.

Solution!

 

Disclaimer:

This may or may not work for you. Because I made it for some very particular situation, and this script helped. So this script checks for two things only. 1st kannel service, 2nd kannel log error for routing failed. I am sure this may or may not help you in same situation because its possible that error can be due to something else. I carefully examined my situation and made script for it. You can get some idea by it and modify the script as required.

Schedule Script to run after every 15 minutes or whatever.

Cron Example

# Run KANNEL MONITOR Script after every 15 minutes
*/15 * * * * /temp/kanneltest.sh

 


the SCript !

mkdir /temp
cd /temp
touch /temp/kanneltest.sh
chmod +x /temp/kanneltest.sh
nano /temp/kanneltest.sh

Copy paste following script. Make sure you read it carefully and modify things accordingly.


#!/bin/bash
# No part of this script is copied from anywhere, you are free to use it, modify or distribute.
# Linux BASH script to check KANNEL service Status and internal component system (example kannel service is ok,but not responding to request giving error in logs
# If KANNEL not responding, then send EMail alert to admin (trigger one time for each status changed)
# Useful for remote admins, who want to be informed when KANNEL have any responding problem.
