There are several ways;

Typing "man nfs" might tell you which version you're operating on, if not, it should tell you how to find out which version you are running.

Also, you could open up the graphical package manager. I don't know know if RHEL uses the same graphical front-end to rpm like Fedora does - yum - but if there's an Add/Remove Programs item in the main menu, then run it, and look around for the nfs packages, and a version number should be right next to it (if not in the package name).

Another option, which is kind of "theoretically, it makes sense", is reading the manpage for rpm and you might be able to find out which version an installed package is.

Thanks for suggestions.....However, I am still not able to find out the correct version number

1. man nfs does not give any information on how to check the version of nfs.

2. Yum is not installed...and system-config-packages (Redhat Package Manager) does not list nfs version anywhere

3. rpm -qa | grep -i nfs shows only one output and it is

nfs-utils-1.0.6

4. rpm -qi nfs-utils however, give some intersting output.

Code:
:Description:
The nfs-utils provides a daemon for kernel nfs server and related tools........"
Does that mean nfs is installed in kernel ????

5. one more thing....."The another I got from google is to use rpcinfo".

rpcinfo -u localhost nfs shows..

Code:
program 100003 version 2 ready and waiting
program 100003 version 3 ready and waiting
program 100003 version 4 ready and waiting...

Any ideas !!

I'm pretty sure "1.0.6" denotes the NFS version you have.

And yes, NFS is in the kernel, as it is a file system (that was developed before the time of userspace file systems - ie. FUSE).

Try nfsstat

nfsstat should provide output like the following:

Code:
Server rpc stats:
calls      badcalls   badauth    badclnt    xdrcall
137273295   0          0          0          0       

Server nfs v3:
null         getattr      setattr      lookup       access       readlink     
428       0% 2149361782 48% 3710191   0% 1595320309 35% 412552442  9% 727       0% 
read         write        create       mkdir        symlink      mknod        
210565420  4% 26842873  0% 3489945   0% 1990773   0% 6         0% 0         0% 
remove       rmdir        rename       link         readdir      readdirplus  
3436170   0% 15695     0% 40911     0% 1129277   0% 19640888  0% 1062412   0% 
fsstat       fsinfo       pathconf     commit       
1330      0% 788       0% 0         0% 2417984   0%
In this example, the server is only running nfs v3 protocol. If you're running v2 and v4, you should have separate sections with stats for data served by version.

yep, I would vote for this. When using nfsstat -s(query server) or nfsstat -c(query client), you can determine which nfs version it's using(the currently used one is with most rpc calls)
