MOUNTPROC_MNT_1: errorcode 13 about nekodrive

[GoogleCodeExporter]

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!

Anyway, can you try NFSV3 instead of NFSV2? They use completely different code.

nothings change..

error output is the following;

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

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...

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!

ok, I'm going to download and debug the application... I'll write back if i 
find something.

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...

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
