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. http://centos.org/docs/5/html/Installation_Guide-en-US/s1-kickstart2-options...

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
