On Linux we can get around this restriction by setting the NET_BIND_SERVICE
capability for the application binary.

This is set up by running
    sudo setcap 'cap_net_bind_service=+ep' /path/to/executable
This capability allows the binary to use systems ports like this even when
not running as root. Thus if you set this capability for your application
you no longer need to edit the export on the NFS server to set "insecure".


I do not know what equivalent "capability" support is available on other
platforms. Please drop me an email if your os of choice has something similar
and I can add it to the README.


DOCUMENTATION
=============
libnfs sources ship with prebuilt manpage(s) in the doc directory.
If you change the manpage sources you need to manually regenerate the new
manpages by running
  cd doc
  make doc


PLATFORM support
=================
This is a truly multiplatform library.

Linux:  - tested with Ubuntu 10.04 - should work with others as well
Cygwin: - tested under 64bit win2k8.
MacOSX: - tested with SDK 10.4 (under Snow Leopard) - should also work with later SDKs and 64Bit
iOS:    - tested with iOS SDK 4.2 - running on iOS 4.3.x
FreeBSD:- tested with 8.2
Solaris
Windows:- tested on Windows 7 64 and Windows XP 32 using Visual Studio 10 (see README.win32.txt for build instructions)
        - tested on Windows 7 64 using MingW on Linux to cross-compile (Debian and Ubuntu tested)
Android:- tested with NDK r10e - running on Android 4.4 (should work starting from 2.3.3)
AROS: - Build with 'make -f aros/Makefile.AROS'
Playstation 2: - Build and install with 'cd ps2ee; make -f Makefile.PS2_EE install'
PlayStation 3: - Build and install the library with 'make -f ps3_ppu/Makefile.PS3_PPU install'


LD_PRELOAD
==========
examples/ld_nfs.c contains a LD_PRELOADable module that can be used to make
several standard utilities nfs aware.
It is still very incomplete but can be used for basic things such as cat and cp.
Patches to add more coverage is welcome.

Compile with :
gcc -fPIC -shared -o ld_nfs.so examples/ld_nfs.c -ldl -lnfs

Then try things like
LD_NFS_DEBUG=9 LD_PRELOAD=./ld_nfs.so cat nfs://127.0.0.1//data/tmp/foo123

LD_NFS_DEBUG=9 LD_PRELOAD=./ld_nfs.so cp nfs://127.0.0.1//data/tmp/foo123 nfs://127.0.0.1//data/tmp/foo123.copy

LD_NFS_UID and LD_NFS_GID can be used to fake the uid and the gid in the nfs context.
This can be useful on "insecure" enabled NFS share to make the server trust you as a root.
You can try to run as a normal user things like :
LD_NFS_DEBUG=9 LD_NFS_UID=0 LD_NFS_GID=0 LD_PRELOAD=./ld_nfs.so chown root:root nfs://127.0.0.1//data/tmp/foo123

This is just a toy preload module. Don't open bugs if it does not work. Send
patches to make it better instead.
