How to setup iscsi target on OEL 5.5

http://fedoraproject.org/wiki/Scsi-target-utils_Quickstart_Guide

RedHat have included an iSCSI daemon which is also installable using yum:

yum install iscsi-initiator-utils

To connect to the target, edit /etc/iscsi/initiatorname.iscsi and change InitiatorName to something you prefer (Remember! it must be in the IQN format, iqn.yyyy-mm.{reversed domain name}:an_easy_to_remember_lablel. I usually use iqn.2009-02.com.hamzahkhan:hostname_of_box). Next start up iSCSId:

/etc/init.d/iscsid start

and use iSCSI target descovery to find the targets on the server:

iscsiadm -m discovery -t st -p $SERVERS_IP

If all is well, it should output the names of all the targets that the initiator is allowed to connect to!

Next, we need to create the disk nodes. To do this, RedHat have provided a nice start up script. This script will login to all the targets that the iSCSI daemon knows about. We have already used the iscsiadm command to tell the iSCSI daemon which targets exist on the server, so using the script is all that is left:

/etc/init.d/iscsi start

On Windows 7 use this note ,

Migrate from VMWare Server to VirtualBox

1.Important: From VMWare Server, start your virtual machines and uninstall VMWare toolbox!

2.Locate the main VMDK file you want converted. It's usually a XML file, or a binary
file with a XML header.

3.From the command line, CD to the location of that file. Say the VMWare disk image to convert is Root_Disk.vmdk.

4.Run the following command to convert to VDI:

C:\Program Files\Oracle\VirtualBox\VBoxManage clonehd --format vdi "c:\Virtual Machines\XP\Windows XP Professional.vmdk" "c:\Virtual Machines\XP\WinXP.vdi"

5.That's it! If you're in Linux, the VDI file will be created under ~/.VirtualBox/Harddisks/.

6.Add that to your media manager and create the virtual machine as you normally would.

Reducing the PDF Page Size when printing

Sometimes we need to print a pdf on a page that is lesser then A4 size. The main reason for this kind of printing is that size reduction. Carrying a A4 PAGE book is not that handy most of the times.

For this we need to reduce the size of the page while printing. Unfortunately in Acrobat PDF Reader this option is not present.

For this we can use the the PDF-XChange Viewer free edition.

Download the PDF-XChange Viewer from http://www.tracker-software.com/product/downloads/

Select File->Print option and Select the Page Scaling as => Custom Scale and Page Zoon as 75% and Select Auto-Center pages in sheets

Please refer to the screen below

After this you can cut the extra white space using a paper cutter.

How to attach a pdf file to an email from a shell script

mutt -s "Training Calendar on ` date +%d-%b-%Y` " -a /tmp/trg_blr.pdf ravi.reddy@oracle.com < /tmp/mailmessage.txt
---

To change the from email address while using mutt
create a .muttrc in the users home directory if it doesnot exist, then enter the feild

set realname="ravi.reddy@oracle.com" this will change the name in the senders name .

How to Hide Username/Passwords in shell scripts

Please refer to this article for more details on this.

I have lot of shell scripts where I have to store my username and passwords for accessing the data. This is a big security rish as my passwords are exposed.

I need some executable which can convert my shell script to exe so that it will be difficult for the people to get my password.

Download the sources from http://www.datsi.fi.upm.es/%7Efrosal/sources/shc-3.8.6.tgz

Extract the tar file

tar xvfz shc-3.8.6.tgz

Make the executable

cd shc-3.8.6
make

cp shc to /usr/bin directory

I have a shell script which fetches some password protected pages , here
there is no other option for me other then embedding the password as the wget does
not support encrypted passwords

for example ,

cat getcookie.sh

#!/bin/ksh
/usr/bin/wget --keep-session-cookies --save-cookies=/home/ias/cookie.txt  -O /home/ias/dd.txt   --input-file=/home/ias/urls.txt --http-user=xx.xxx@test.com --http-password=xxxxxxx > /dev/null
cat /home/ias/cookie.txt  | grep test  | cut --fields=7 > /home/ias/cookie.txt

with the shc script I can convert the shell script as executable so that the passwords are hidden
from the people who has access to my unix system.

Run the shc command

shc -f getcookie.sh

This creates the getcookie.sh.c and getcookie.sh.x where .c is the c source file and .x is the executable.

Now run the getcookie.sh.x executable and change the password from the original getcookie.sh script.

Please refer to the http://blogs.koolwal.net/2009/01/20/howto-encrypting-a-shell-script-on-a-linux-or-unix-based-system/
for more details on this.

Please refer to the link http://www.halfdone.com/Articles/XMailInstall/ for more details on this.

Here are the simplified steps to configure the XMail Server’s on Windows Machine

1. Download the XMail Server from http://www.xmailserver.org     

2. Extract this to a directory say C:\xmail-1.27

3. Copy the exe’s and dll’s to C:\xmail-1.27\MailRoot\bin directory

4. Create the HKEY_LOCAL_MACHINE\SOFTWARE\GNU\XMAIL. Create the Sting (REG_SZ) values called MAIL_ROOT and MAIL_CMD_LINE. For the value of MAIL_ROOT put in the "MailRoot folder" location like C:\xmail-1.27\MailRoot. For MAIL_CMD_LINE you can leave it blank or put in "-Pl -Sl -Ql -Fl -Cl -Ll"

5. Here we are using the default domain , that is xmailserver.test , so no need to modify the configuration files.

6. Run xmcrypt.exe to create an encoded password. It's used in the format of XMCRYPT.EXE <password>.

xmcrypt.exe welcome1

1100161115041616120a1701

How to Configure Exchange Connector

1. Try to get hold of a system where exchange and active directory are installed.

2. Install AD Connector on the OIM Server and provision a user (For testing purpose)

3. Install Microsoft Exchange connector on the OIM Server. Please note that you need the Remote Manager only when you are using the exchange server 2007. Otherwise you do not need to any thing on the OIM Server.

4. Create a IT Resource for Exchange and leave all the attributes as blank.

5. Run the “Exchange Mail Store Lookup Reconciliation” task , before running this task scheduler change the “AD IT resource” attribute to the AD Connector that you created in the step no:2.

6. This schedule task populates the “Lookup.ExchangeReconciliation.MailStore” lookup values. For example in my case it populated my mail box name as “celvpint0309-ADInstance~CN=Mailbox Store (MSBOX),CN=First Storage Group,CN=InformationStore,CN=MSBOX,CN=Servers,CN=First Administrative Group,CN=Administrative Groups,CN=MSExchange2003Org,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=vm,DC=oracle,DC=com”

7. Now provision the AD User to the Exchange System. Only mandatory fields are Email Alias Name and the mail store name.

8. Now log in to the AD Server machine and check the AD User. For the exchange user you will see more attributes in the AD User TAB.

How to use the ADAM Connector with OIM
