FAQ
Hi, I am Ken.. I am trying to add dud(driver update disk) to centos5.6
using network method, I can successfully add dud to centos5.6 using
http and ftp method, but fail when using nfs method. However those all
three methods are officially supported in the centos5.6.

As indicated in the centos5.6 website, we can see they not only
support http, ftp, but also nfs.

------------------------------------------------------------------------------------------
driverdisk (optional)
Driver diskettes can be used during kickstart installations. You
must copy the driver diskettes's contents to the root directory of a
partition on the system's hard drive. Then you must use the driverdisk
command to tell the installation program where to look for the driver
disk.

driverdisk <partition> [--type=<fstype>]

Alternatively, a network location can be specified for the driver diskette:

driverdisk --source=ftp://path/to/dd.img
driverdisk --source=http://path/to/dd.img
driverdisk --source=nfs:host:/path/to/img

*
<partition> Partition containing the driver disk.
*
--type= File system type (for example, vfat or ext2).
------------------------------------------------------------------------------------------
In my experiment, I make my dud address in the kickstart file like below:

driverdisk --source=nfs:9.122.90.239:/deployment/dud-2.6.18-128-64.centos.iso

but it fails to load the dud when centos begin to install.

do you have any suggestion to me? Thanks

    Hello Ken.

    I don't use NFS, can you actually reach your NFS machine
    from another machine on your LAN to get some sort of file
    listings from it, like an apache directory listing? This
    would tell you that the machine is actually reachable.

    As with any network problems, I would recommend installing
    Wireshark on both machines you want to be able to talk to
    each other via your LAN. You can then run Wireshark on both
    machines and get a realtime diagnosis of what's happening on
    each network interface, complete with any error messages.

    Much better than trying to 'pin the tail on the donkey
    blindfolded' so to speak, which I consider diagnosing
    network problems can be compared to, without being able
    to actually see the packets flowing between the two networks
    with some sort of diagnostics software.

    Kind Regards,

    Keith Roberts

    #showmount -e <host IP or FQDN>

    will list available NFS shares.

    Common problems can be version of NFS, firewalled ports and NFS server
    not allowing access to particular IP/subnet.
