The following is a simple (and very row) init script for Symantec Backup Exec Agent for Linux.

I wrote it because I really hate to execute script not registered with chkconfig on a production systems.

I’ve added the “status” function by checking if an executable called “beremote” is listening on 10000/tcp on IPv4 on the localhost.

If you are planning to run ralus on a different TCP port, please fix the script.

The following is the script :

#!/bin/sh
#
# RALUS Control Script
# chkconfig: 2345 99 01
# Description: Here is a little startup/shutdown script for RedHat/CentOS systems

This simple How-To will explain a raw and dirt method to daemonize to http manager for ARECA Raid Controller.

If you have this controller on your system you should find in the bundled CD-ROM the following folder :

root
PACKAGES -> Linux -> CLI -> version -> i386 -> cli32

PACKAGES -> Linux -> CLI -> version -> x86-64 -> cli32

PACKAGES -> Linux -> HTTP -> version.x.y.x -> i386 -> archttp32

PACKAGES -> Linux -> HTTP -> version.x.y.x -> x86-64 -> archttp32

Create a folder in your /usr/local folder called “areca” e and create into it two folders called “http” and “cli”
Copy the “cli32″ and “archttp32″ executable file that match your architecture (i386 or x86-64) in the specified folder, so you should have something similar :

[root@relay ~]# ls -lahR /usr/local/areca/
/usr/local/areca/:
total 20K
drwxr-xr-x  4 root root 4.0K Feb 12 10:28 .
drwxr-xr-x 13 root root 4.0K Feb 12 10:26 ..
dr-xr-xr-x  2 root root 4.0K Feb 12 10:27 cli
dr-xr-xr-x  2 root root 4.0K Feb 12 10:42 http

/usr/local/areca/cli:
total 1.6M
dr-xr-xr-x 2 root root 4.0K Feb 12 10:27 .
drwxr-xr-x 4 root root 4.0K Feb 12 10:28 ..
-r-xr-xr-x 1 root root 1.6M Dec 26  2008 cli32

/usr/local/areca/http:
total 1.6M
dr-xr-xr-x 2 root root 4.0K Feb 12 10:42 .
drwxr-xr-x 4 root root 4.0K Feb 12 10:28 ..
-r-xr-xr-x 1 root root 1.6M Dec 26  2008 archttp32
-rw-r--r-- 1 root root   91 Feb 12 10:42 archttpsrv.conf

Create a new file called “areca” in your /etc/init.d folder with the following content :

#!/bin/sh
#
# Startup script for the ARECA RAID CONTROLLER HTTP Monitor
#
# chkconfig: 2345 62 38

# This script is realeased under the terms of the GPL.

# Source function library
. /etc/init.d/functions

RETVAL=0

start() {
echo -n $"Starting ARECA HTTP Manager: "
daemon /usr/local/areca/http/archttp32 2>&1>/dev/null &
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && touch /var/lock/subsys/archttp32
return $RETVAL
}

stop() {
echo -n $"Stopping ARECA HTTP Manager: "
killproc archttp32
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/archttp32
return $RETVAL
}

restart() {
stop
start
}

reload() {
echo -n $"Reloading ARECA HTTP Manager: "
killproc archttp32 -ALRM
RETVAL=$?
echo
return $RETVAL
}

case "$1" in
start)
start
;;
stop)
stop
;;
status)
status archttp32
;;
restart)
restart
;;
condrestart)
[ -f /var/lock/subsys/archttp32 ] && restart || :
;;
reload)
reload
;;
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|reload}"
exit 1
esac

exit $?
#---End of file---

Assing to it the right permission and ownership

chmod 755 /etc/init.d/areca
chown root:root /etc/init.d/areca

You should also place in the executable file folder the configuration file, called “archttp32srv.conf” with the following content :

[GENERAL]
BindingIp=0.0.0.0
HTTPPort=81
SMTPPort=25
ScanPci=YES
ScanRs232=NO
ScanInband=NO
ConnInfo=NO

[MAIL]
Server=MAIL.SERVER.IP.ADDRESS # Please Change ME
Sender=SENDERNAME # Please Change ME
SenderMail=SENDERMAIL # Please Change ME
Account=
Password=
MailToName1=RECEIVERNAME # Please Change ME
MailToName2=
MailToName3=
MailToName4=
MailAddr1=RECEIVERMAIL # Please Change ME
MailAddr2=
MailAddr3=
MailAddr4=
EvtLevel=3
NotifyForNoEvent=NO

[SNMP]
TrapIp1=SNMP.SERVER.IP.ADDRESS # Please Change ME
TrapIp2=0.0.0.0
TrapIp3=0.0.0.0
TrapPort1=162
TrapPort2=162
TrapPort3=162
Community=public
EvtLevel=3

And configure it for startup at boot time.

chkconfig areca on

I know it very dirt, but I had no time left to search a better way, maybe in the future.

Hope this help

This simple init script is for daemonize freshclam (Clamd Antivirus Updater) on RHEL or CentOS.

Create a brand new file called freshclam in /etc/init.d/ with the following content :

#!/bin/sh
#
# Startup script for the Clam AntiVirus Update Tool
#
# chkconfig: 2345 62 38
# description: freshclam is an update daemon for Clam AV database.
#

# pidfile: /var/run/clamav/freshclam.pid
#
# Author: Riccardo Riva
# WebSite: http://www.riccardoriva.com
#
# This script is realeased under the terms of the GPL.
#====================================================================

# Source function library
. /etc/init.d/functions

# Get network config
. /etc/sysconfig/network

test -f /etc/freshclam.conf || exit 0

RETVAL=0

start() {
echo -n $"Starting freshclam: "
daemon /usr/bin/freshclam -d -p /var/run/clamav/freshclam.pid
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && touch /var/lock/subsys/freshclam
return $RETVAL
}

stop() {
echo -n $"Stopping freshclam: "
killproc freshclam
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && rm -f /var/run/clamav/freshclam.pid /var/lock/subsys/freshclam
return $RETVAL
}

restart() {
stop
start
}

reload() {
echo -n $"Reloading DB: "
killproc freshclam -ALRM
RETVAL=$?
echo
return $RETVAL
}

case "$1" in
start)
start
;;
stop)
stop
;;
status)
status freshclam
;;
restart)
restart
;;
condrestart)
[ -f /var/lock/subsys/freshclam ] && restart || :
;;
reload)
reload
;;
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|reload}"
exit 1
esac

exit $?

Assign to it corect ownership and permission :

chown root:root /etc/init.d/freshclam
chmod 755 /etc/init.d/freshclam

Test if the scripts works correctly on your system with the following commands :

service freshclam start
service freshclam stop
service freshclam restart
service freshclam reload
service freshclam condstart

If all works fine you should add freshclam to the automatic startup services with the following command :

chkconfig freshclam on

Hope this help

This post will assume you just have a fully functional working mail server and you want do download all emails from some mailboxes located on another mail server, tipically located on your service provider’s one.
This post guide will guide you to install and configure fetchmail and use it with your RHEL 5 or newer, you should use all the following information also with CentOS without change any line, but you shoud adapt it to every Linux distribution.
Most likely you want to setup fetchmail to download your domain mailbox over pop3 and inject into Postfix (or whatever you use as MTA).

To install fetchmail use the following :

yum install fetchmail -y

You should decide how to use fetchmail :

* as a daemon
* as a cron scheduled task

The following is a very simple init script for Oracle on Red Hat Enterprise Linux.
I’m using it successfully in RHEL 5.2 but you can use it on other systems, only double check the various path.

Create this script and put it in your /etc/init.d/ directory

Make this script excutable

Use “chkconfig” to set the startup or the shutdown for this script in the desired runlevels.

Hope this help avoid wasting time

Here is the code for an advanced startup/shutdown script for JBoss.

I’m using it with JBoss 3.2.6 on a RHEL 5.2 Advanced Platform, and all works well.

I’ve added the “status” function for use it in a cluster suite and a new function to check if Oracle DB Server is up and running, otherwise JBoss doesn’t deploy well all developers files.

When you use “start” function, the script use a simple “tnsping” based function that loop into themselves until Oracle is not fully working and then sleep other 10 seconds to start JBoss.

Today I had to install an ArcServer Unix agent on a brand new Linux system, and as any times i can’t find an init script that allow to start/stop/restart or see the agent status.

Google wasn’t my friend because I was without internet access so I’ve decided to write it by myself.

follow the Linux Init Script for ArcServe Unix Agent :

#! /bin/sh
#
# Author: Riccardo Riva
#

# System startup script for the inet daemon
#
### BEGIN INIT INFO
# Provides: uagent
# Default-Start: 2 3 5

fi

if [ -e /etc/rc.status ]; then
. /etc/rc.status
fi

# Determine the base and follow a runlevel link name.
base=${0##*/}
link=${base#*[SK][0-9][0-9]}

uagent_bin=/opt/uagent/uagent
return=$rc_done

# Reset status of this service.

case “$1″ in
start)
