Because I wanted to have some fun.
nfs2-0.1.tar.gz (2014-10-08).
This is a big hack.
Ah, in the README below I forgot to mention that the readdir function might be buggy. I don't know if I compute the size correctly. I only calculate the size of the XDR structure I return. Maybe I should take into account other bytes? Anyway, so be it.
You can dig for "nfs-server-2.0.tar.gz" on the internet for an old nfs2 implementation. I doubt it will work though. (My computer is a 64 bits machine and nfs-server-2.0 does not seem to work with such machines.) (Digging for "nfs-server-2.0.tar.gz tsx-11" is better.) There is also the linux kernel code to look at for some documentation/implementation.
Here is the README file included:
This is a hackish nfs2 userland server. Might work with an ext2/3/4 filesystem. You must run: mount/mount_server localhost /tmp/debian.stable and as root: nfs/nfs_server /tmp/debian.stable to serve /tmp/debian.stable to some host. I could make only one program by mixing those two I guess... There are surely bugs in there. Each lookup/create/mkdir calls new_file, which smokes a bit of memory. If the client lookups the same name several times, each time some memory is wasted. On the other hand, retrieving the filename from a "fhandle" is O(1). Ah yes, the code is non-portable, full of stuff like "*(unsigned long *)fhandle = ul". There is also a "cookie cache" to store 64 bits cookies returned by telldir. NFS2 deals with cookies of 32 bits, so a translation is required. Veeeeeery hackish once again, eats lots of memory. But, THIS IS A HACK! THERE IS NO SECURITY AT ALL, DON'T USE IN PRODUCTION! http://sed.free.fr/debian486/nfs2.html public domain stuff to generate code from .x files: rpcgen -a -C <file>.x
