Windows NFS 4.1 Client Instructions

1. Building from Source

Windows Vista, Windows Server 2008 R2, or Windows 7 (Windows XP and previous versions are not supported)
Microsoft Visual Studio 2010
Windows Driver Development Kit (WinDDK 6000 or later)
ms-nfs41-client source code:
> git clone git://citi.umich.edu/projects/ms-nfs41-client.git

WinDDK does not include the ldap library, so we build the rpc library and nfs client daemon with Visual Studio 2010.

Open Windows Explorer and navigate to ms-nfs41-client\build.vc10.
Make a copy of env.props.example, and rename it to env.props.
Open env.props in a text editor, and verify that the value in <WDKPATH>C:\WinDDK\7600.16385.0</WDKPATH> points to your WinDDK installation.
Open the solution file ms-nfs41-client.sln in Visual Studio 2010.
Select the desired configuration and platform (accessible via Build->Configuration Manager).
Right-click on the daemon project and select Build. The project and its dependencies should build without errors. The resulting binaries, nfsd.exe and libtirpc.dll, can be found under ms-nfs41-client\build.vc10\x64\Debug\.

From the Start menu, open the WinDDK 'Checked Build Environment' for the target platform.
Change directory to ms-nfs41-client and type build. All projects should build without errors.

Open a WinDDK 'Checked Build Environment' as Administrator in this directory (right click and 'Run as administrator').
Create a certificate for test-signing the driver (Creating Test Certificates):
> makecert /pe /ss PrivateCertStore /n CN=nfs41_driver nfs41_driver.cer
Use the certificate to sign nfs41_driver.sys (Test-Signing a Driver File):
> signtool sign /v /s PrivateCertStore /n nfs41_driver /t http://timestamp.verisign.com/scripts/timestamp.dll path\to\nfs41_driver.sys

ms-nfs41-client binaries: nfs41_driver.sys, nfs41_np.dll, libtirpc.dll, nfs_install.exe, nfsd.exe, nfs_mount.exe
ms-nfs41-client configuration files: nfs41_driver.cer, nfs41rdr.inf, install.bat, uninstall.bat, etc_netconfig, ms-nfs41-idmap.conf
Microsoft Visual Studio 2010, or Microsoft Visual C++ 2010 Redistributable Libraries (x86 or x64). An installer for the redistributable libraries are included with binary releases.

Copy or extract all ms-nfs41-client binaries and configuration files into a directory that's convenient for testing.
Run vcredist_x*.exe to install the Visual C++ Redistributable Libraries.
Double-click on nfs41_driver.cer and select 'Install Certificate', then place it in the 'Trusted Root Certificate Authorities' store.
Open a command prompt as Administrator in this directory.
Install the driver and update the registry:
> install.bat
Copy configuration files:
> mkdir C:\etc
> copy etc_netconfig C:\etc\netconfig
> copy ms-nfs41-idmap.conf C:\etc\
Allow windows to load test-signed drivers:
> bcdedit /set testsigning on
Reboot.

Open C:\etc\ms-nfs41-idmap.conf in a text editor.
Uncomment the ldap_hostname and ldap_base lines, and configure as appropriate to match your ldap server configuration (we'll add suggestions later).

If you've installed the binary distribution, you'll find two versions of the nfs client daemon: nfsd.exe and nfsd_debug.exe. nfsd.exe is built to run as a service, and does not provide easy access to debug output. We strongly recommend trying nfsd_debug.exe first (using the Instructions below) to verify that you can start the daemon and mount/unmount an nfs share. You can then close nfsd_debug.exe and start running nfsd.exe as a service with:
> nfsd.exe -install.

From a Windows command prompt, run nfsd.exe to start the nfs client daemon. Leave this running in the background until all mapped drives are unmounted.
Usage:
> nfsd.exe -d <debug level> [--noldap]
- <debug level> determines the log verbosity (1, 2, 3 or 0 to disable)
- --noldap disables id mapping and uses a default uid=666 and gid=777

From a Windows command prompt run nfs_mount.exe to mount a share:
> nfs_mount.exe Z: <server_name>:\
To specify the security flavor, add the 'sec=' mount option with sys, krb5, krb5i, or krb5p:
> nfs_mount.exe -o sec=<flavor> Z: <server_name>:\
You can later unmount with:
> nfs_mount.exe -d Z

Cygwin, including packages gcc-core, make, time, tirpc, git
Connectathon Test Suite
ms-nfs41-client source code (patches for connectathon are located in ms-nfs41-client\tests)

Extract nfstests.zip into a directory that's convenient for testing (i.e. cthon04).
Open a Cygwin shell, and change directory to cthon04.
Create a git repository to track changes:
> git init
> git add *
> git commit -m "files from nfstests.zip"
Apply all cthon patches:
> git am /path/to/ms-nfs41-client/tests/*.patch
Build the tests:
> make
Run the test suite on a mounted directory:
> ./runtests -a -t z:/testdir

krb5p security with AES keys do not work against the linux server, as it does not support gss krb5 v2 tokens with rotated data.
When recovering opens and locks outside of the server's grace period, client does not check whether the file has been modified by another client.
If nfsd.exe is restarted while a drive is mapped, that drive needs to be remounted before further use.
Symbolic links are not supported in Cygwin. Connectathon's basic test8 and special test nfsidem have been commented out.
Does not allow renaming a file on top of an existing open file. Connectathon's special test op_ren has been commented out.
The Windows DFS client interferes with some requests, indicated by long delays during operation. To disable the DFS client, use regedit.exe to navigate to HKLM\System\CurrentControlSet\Services\Mup, and add a REG_DWORD entry named 'DisableDfs' with a value of 1.
