printing from opensuse to fuji xerox ApeosPort 450I

opensuse 11.1 detects all the nework printers automatically. impressive!

but there is no driver for this printer and i could not find the ppd file for it. ppd - PostScript Printer Description


i use Xerox DocuPrint 4508 Foomatic/lj4dith, and it works!!!!

i managed to print out a beautiful test page... which says Printed Using CUPS v1.3

www.cups.org


btw i use "windows printer via samba" smb://domain-name/servername/printername

and key in your windows domain id and password.

it works!!

iso

all about ISO


mount an iso file to a folder

mount -t iso9660 -o loop /home/fs/cd101.iso /mnt

If this don't work...

First of all, you'll have to check whether certain options are included in your kernel. If you're using a standard kernel from one of the major distributions, it's pretty likely that everything necessary is already included so you might want to skip this step. If you have a self-compiled kernel - and I recommend everyone to compile the kernel oneself - you'll have to enable the following options in your kernel:

in Device Drivers > Block Devices
Loopback device support

in File Systems > CD-ROM/DVD Filesystems
ISO 9660 CDROM file system support
[*] Microsoft Joliet CDROM extensions
[*] Transparent decompression extension

kvm with opensuse

using kvm on opensuse 11.1 is easy.

http://www.linux-kvm.org/page/HOWTO


my hardware: hp elitebook 6930p

install opensuse 11.1

boot cd with acpi=off

don't use auto configuration during the install process

i disable auto login too and did an internet update and it is so slow... mainly i guess due to my bb connection.. it keep breaking..

so u can skip internet update

to install KVM follow this:

http://en.opensuse.org/KVM


I installed windows 2008 server using a 10gb image file.

create image file
qemu-img create -f qcow2 disk.img 10G

How do I use dd command to create an ISO image?

Put CD into CDROM

Do not mount CD. Verify if cd is mounted or not with mount command:

# mount

If cd was mouted automatically unmout it with umount command:

# umount /dev/cdrom

OR

# umount /mnt/cdrom

Create CD-ROM ISO image with dd command:

# dd if=/dev/cdrom of=/tmp/cdimg1.iso

Where,

  • if=/dev/cdrom: Read from /dev/cdrom (raw format)
  • of=/tmp/cdimg1.iso: write to FILE cdimg1.iso i.e. create an ISO image
src: http://www.cyberciti.biz/tips/linux-creating-cd-rom-iso-image.html


boot the guest from a iso file

qemu-kvm -m 256 -hda disk.img -cdrom winxpsp2.iso -boot d
-boot d instruct qemu to boot from cdrom

what nic are supported?

qemu-kvm -hda vista1.img -net nic,model=?,macaddr=00:16:3e:23:38:45 -net user -cdrom BootMedia.iso -boot d &


opensuse:/kvm-disk # qemu: Supported ISA NICs: ne2k_isa
qemu: Supported PCI NICs: i82551 i82557b i82559er ne2k_pci pcnet rtl8139 e1000 virtio


i82557b is supported by my vista

Insert KVM Modules

Insert the kvm modules as follows (as root)

For Intel processors

opensuse11:~ # modprobe kvm
opensuse11:~ # modprobe kvm-intel

For AMD processors

opensuse11:~ # modprobe kvm
opensuse11:~ # modprobe kvm-amd

To confirm the modules OK,

opensuse11:~ # lsmod | grep kvm
kvm_intel 67824 0
kvm 182936 1 kvm_intel

However, this setting lost on a reboot.

To insert this module at boot time, Click Computer – YaST – System – “/etc/sysconfig editor”. This launches the sysconfig editor.

Click “+” next to “system” and then “+” next to Kernel. Click “MODULES_LOADED_ON_BOOT“, in the right-pane, enter “kvm kvm-intel kqemu” without quotes (”kvm kvm-amd kqemu” for AMD) in the setting box and click finish. Click OK on the confirmation window.

Now, we are all set to configure and run a guest OS on your openSUSE.



Installation of Windows guest paravirtual network drivers

opensuse:/kvm-disk # qemu-kvm -hda AD.img -cdrom /home/fs/Desktop/NETKVM-20081229.iso -net nic,model=virtio
Warning: vlan 0 is not connected to host network

AD.img is the image file where i had installed a windows 2008 to function as the Domain Controller

-cdrom /home/fs/Desktop/NETKVM-20081229.iso

The iso file contained the paravirtualized network drivers that i downloaded; when the Windows 2008 boot up, the cdrom drive will behave as if there is a CD containing the drivers needed for installation.

adding tap devices using YaST

u must disable network manager from managing the network and use if-up, if-down...

persistent tunnel

no tunnel group , no tunnel owner

must install tunctl package

for me, i need to add my proxy server in YaST control centre->network services->proxy
