9 years ago Hi, versions >= 0.5 use new NFS libraries in full c#, and maybe there are
problems. I will investigate as soon as possible. Thank you for the feedback!Original comment by mirko.ga...@gmail.com on 1 Oct 2010 at 10:25

9 years ago Anyway, can you try NFSV3 instead of NFSV2? They use completely different code.Original comment by mirko.ga...@gmail.com on 1 Oct 2010 at 10:26

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this

do you want to share the source code with me, i can debug it also...Original comment by freakm...@gmail.com on 1 Oct 2010 at 9:06

At http://code.google.com/p/nekodrive/source/checkout you can get the latest
version of the code using ankhsvn for visual studio, tortoise or any compatible
svn client. Let me know if you find something. Till now I debugged on VxWorks
6.4 NFS Server and everything works fine, today I'm going to try with your
configuration. Anyway error code 13 means access denied. Thank you! Original comment by mirko.ga...@gmail.com on 2 Oct 2010 at 8:01

9 years ago I just found something about security on Ubuntu NFS server
if i change the export settings like the following
/home/freak/Projects/TOVideosTEST
192.168.0.14(rw,no_subtree_check,sync,insecure,anonuid=1000,anongid=1000)
anonuid and anongid values have been got using "id" command in linux
the mount problem has gone. However, there is something wrong about the
permissions of creating directory and files. NFSV2 and NFSv3 have made the
folders and files permissions differently, I've found something in your code
and try to fix it, but permission appointments have not been set correctly. I
need deeper investigation on your project...Original comment by freakm...@gmail.com on 2 Oct 2010 at 2:38

9 years ago I don't know permission appointment of NFSV3 working correctly on VxWorks but
the correct permission appointment on Ubuntu NFS Server is the following;
0777 permission mask
7 in bit order 111
NFS is searching the integer bit by bit. Every 3 bit has the permission
information of the file and directory. so if we want to full access and execute
permission to the file or folder, NFS server expects 9 bit like 111111111. The
C# calculation of this bits are the following;
/* Calculate Permission */
byte userP = 7; byte groupP = 7; byte otherP = 7;
int permission = 0;
permission = (((int)userP) << 6) | (((int)groupP) << 3) | ((int)otherP);
/* --- */
I've modified the CreateDirectory and CreateFile procedures according to the
this permission thing, followings are the proc contents
public void CreateDirectory(string DirectoryFullName)
