Vmware tools on oracle linux 5.7

WladyX — Tue, 29 Nov 2011 14:45:16 +0000

When installing Oracle Linux 5U7 as a Guest OS on VMWare fusion 4, you will probably run into the “no module ehci-hcd found for kernel 2.6.32-200.13.1.el5uek” during the VMWare Tools installation process. This error is caused by missing usb kernel modules in /lib/modules/2.6.32-200.13.1.el5uek. You can easily solve this by opening a Terminal session, substitute the user by root (su – root) and executing the command below.

cp /lib/modules/2.6.18-274.el5/kernel/drivers/usb/host/?hci-hcd.ko \

/lib/modules/2.6.32-200.13.1.el5uek/kernel/drivers/usb/host

Now you can start the installation of VMWare tools by executing

./vmware-install.pl

Red Hat / CentOS: Swap / Change Ethernet Aliases

WladyX — Fri, 16 Sep 2011 11:51:25 +0000

Open each interfaces configuration file:

/etc/sysconfig/network-scripts/ifcfg-eth0 – eth0 configuration file
/etc/sysconfig/network-scripts/ifcfg-eth1 – eth1 configuration file

Open file for eth0 using vi, type:
vi /etc/sysconfig/network-scripts/ifcfg-eth0
Add the following line:

HWADDR=

Here is my sample config file:

# Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper)
DEVICE=eth0
BOOTPROTO=static
DHCPCLASS=
HWADDR=00:19:B1:2A:BA:B8
IPADDR=10.10.11.24
NETMASK=255.255.255.192
ONBOOT=yes

Save and close the file. Update /etc/sysconfig/network-scripts/ifcfg-eth1 file with correct HWADDR entry. Once done restart networking or just reboot the server:
# reboot

Make sure that both the server and the client resolve each others hostnames.
Disable firewall on the client/or permit access to the 5555 port.

Check if xinetd is installed and running:
service xinetd status
if it is not then:
yum install xinetd

create /etc/xinetd.d/omni:
service omni { socket_type = stream protocol = tcp wait = no user = root server = /opt/omni/lbin/inet server_args = inet -log /var/opt/omni/log/inet.log disable = no }

service xinetd start

go to the HP-UX kit folder
./omnisetup.sh -server dpserver.fqdn -install da
