Dual boot Ubuntu and Windows 7, with Safeboot / Mcafee Endpoint Encryption

First you need to install Windows 7, and safeboot / Mcafee endpoint protection.

Then you need to take a backup of the MBR, this is done with a Ubuntu live cd, run this commands:

dd if=/dev/sda of=/path/safeboot.mbr bs=512 count=1

 

Put it on a USB flash drive or something else, that you can access after the installation.

After you have make a backup of the MBR, just install Ubuntu the normally way, after you have make changes to grub2 config files.

cp /path/safeboot.mbr /boot/
nano /etc/grub.d/40_custom

At the buttom of this files you need to insert this:

menuentry "Windows 7" {
set root='hd0,msdos1'
chainloader (hd0,msdos5)/boot/safeboot.mbr
boot
}

Where set root=’hd0,msdos1′ is becuase my windows 7 root partition is locate on disk 0, and msdos partition 1, and chainloader (hd0,msdos5)/boot/safeboot.mbr is because my ubuntu partition is located on disk 0 and msdos partition 5.

Upgrade firmware on Dellservers running XenServer and get Dell Openmanage aswell

First you need to enable some standard Repos first

vi /etc/yum.repos.d/CentOS-Base.repo

Enable base and updates.

Then you need to enable Dell yum Repos

wget -q -O - http://linux.dell.com/repo/hardware/latest/bootstrap.cgi | bash

This will automatically create the repo files in /etc/yum.repos.d
Next we will install Dell OMSA (Openmanage) and the firmwall tools needing to upgrade firmware on a Dell Server.

yum install srvadmin-all firmware-tools

 

Then we have to start the Dell Openmanage software this can be done with

/opt/dell/srvadmin/sbin/srvadmin-services.sh start

And after this we can run

/opt/dell/srvadmin/sbin/srvadmin-services.sh status

To check that the Dell Openmanage is running okay.
Now you just need to enable port 1311TCP in the firewall of yours Xenserver

nano /etc/sysconfig/iptables

Now add the following line:

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 1311 -j 
ACCEPT

And restart Xenserver firewall with this commands:

service iptables restart

Now you should be able to browse to https://IPADDROfXenserver:1311 and logon with root and the root password.

If you want to enable SNMP Traps:
To make SNMP Traps working in DOM, you need to enable it:

nano /etc/snmp/snmpd.conf

insert at the buttom of the file:

trapsink IPADDR Communityname

And then restart SNMPD

service snmpd restart

To update Dell firmware tools, you can use this commands:

yum install $(bootstrap_firmware)
update_firmware --yes

This will run for some time.
