I can give some pointers to getting a cross-compile toolchain setup though. You won't want to use the buildroot that is available on the WD website as this comes with only GCC3.4. You will need a buildroot that has GCC4.x to be able to build kernel modules as it looks like the kernel for the MyBook was built using GCC4.x (I forget the exact version now and don't really have a method of checking). Download an older version of buildroot until you are able to get that to compile. It took me quite a few different versions until I could get it to compile correctly. Also if it helps, I did build the nfs.ko module needed for the kernel a while back when I was building the cifs.ko module. You will still need nfs-utils but atleast you may not need to compile the kernel module. You can get it here: http://files.doylenet.net/linux/mybook/modules/2.6.17.14/nfs.ko Best of luck compiling the rest! Hi Christian

Do you still have time to do this? would be great if you are able to publish it here on your blog Hi Ryan,

A common mistake people make is to hit tilde dot without hitting RETURN first. Thanks for the great writeup. To disconnect from the “cu” program, you need to type these three characters:

I recall when we upgraded our Active Directory to 2008R2, I had problems with authentication. I tried playing around with the security policies on the domain controllers but I eventually setup a 2003R2 domain controller as well for authentication. I'm sure people will find your info helpful. Cheers Ryan Hi Daren

One note: if you are authenticating against a Windows 2008R2 the default Samba install from YUM will not work. Winbind will not play nice with 2008R2. You will need to upgrade to Samba 3.4.7. Here is a site that has a decent explanation of the problem and the RPM's needed: http://itnervecenter.com/content/samba-34-centos-5-rpms-available-resolve-winbind-issues-windows-server-2008-r2 I mixed this in with your info and was able to get my CentOS 5.5 box authenticating perfectly against a Server 2008R2 Domain, and yes I am running this domain at the full 2008R2 Function Level. Thank you very much. Daren Great tutorial, very helpful, extremely complete and well done.

This is after maybe 20 minutes. I've half insulated the crystal as well, but I'd say the shift from winxp to freebsd made the biggest shift. I can't see any way to improve this, as it can't report an offset lower than 1us, and its not really moving around like it did on winxp. Before I changed it, I managed to get the winxp out to 400us offset by opening a window and turning the fan on. Not exactly stable.
