This article describes how to get an LDIF file using ICE from a script launched by Cron, and receive an email of the output.

What you need is:

• "ICE" package (my version is novell-NOVLice-8.8.1-7.i386.rpm). The package is available in the Setup directory of the eDirectory source installation CD.
• A local (server) Linux user that will run the script in its crontab
• The modified script to handle your servers, users, and tree references
• Smtp relay host information

Installation

1. Install the ICE package:

myserver:/home/rvi/mountTMP/setup # rpm -ivh novell-NOVLice-8.8.1-7.i386.rpm
Preparing...                ########################################### [100%]
  1:novell-NOVLice         ########################################### [100%]
myserver:/home/rvi/mountTMP/setup #

2. Create a directory where you will put your LDIF output. For this example, "backup" directory is created in /opt/novell/eDirectory.

myserver:/opt/novell/eDirectory # md backup

The script will create the LDIF file, compress it, and manage its history.

3. Define "Myxxxx" variables and check System Variables.

#!/bin/bash
##FULL EDIRECTORY backup via Ice

##System Variables:
Wdir=/opt/novell/eDirectory/backup
CDate=`date +%Y%m%d`
FLdif=Ldif-$CDate.ldif
Flog=Icelog-$CDate.log
IceDir=/opt/novell/eDirectory/bin

##Define your environment variable:

Mytree="TESTTREE"
MySrv="10.120.130.140"
MyUser="cn=bck,ou=system,o=otest"
MyPwd="bckPwd"

cd $Wdir

$IceDir/ice -l$Flog -SLDAP -s$MySrv -p389 -d$MyUser -w$MyPwd -csub -Fobjectclass=* -DLDIF -f$FLdif

## Compress ldif and log Files

gzip $FLdif
gzip $Flog

##Remove Files older than 7 days

find /opt/novell/eDirectory/backup -name 'Icelog-*' -mtime +7 -exec rm {} \;
find /opt/novell/eDirectory/backup -name 'Ldif*' -mtime +7 -exec rm {} \;

4. Modify access rights for the script to restrict the access to all but the owner of the file.

myserver:/opt/novell/eDirectory # chmod 700 IceCron.sh

Configure the Crontab of your local Linux user to launch the script. The examples below will launch the scripts at 18h30, from Monday to Friday:

myserver:/opt/novell/eDirectory # crontab -e

30 18 * * 1,2,3,4,5 sh /opt/novell/eDirectory/backup/IceCron.sh

5. To receive an email of the ICE output, add your email address at the beginning of crontab -e:

MAILTO=adminsupport@mycompany.com

Example:

MAILTO=adminuser@mycompany.com
#MAILTO=root
30 18 * * 1,2,3,4,5 sh /opt/novell/eDirectory/backup/IceCron.sh

6. Modify the SMTP relay host of the local Linux server to send email outside of the local machine. First, modify in "/etc/postfix/main.cf":

relayhost = mysmtpserver.mycompany.com

and then modify in "/etc/sysconfig/postfix":

POSTFIX_RELAYHOST="mysmtpserver.mycompany.com"

Result
