linux noob's NFS question on mounting directories

Hey,guys,I'm really new to Linux and Fedora Core
During these days,I met a problem when configuring NFS for server and client,because my client cannnot mount /home or /media directory from my server. My exports file is like this:
/home 192.168.104.3(rw,no_root_squash,sync)
/media 192.168.104.3(rw,no_root_squash,sync)

when I try to mount my /home directory from the server like:

mount 192.168.104.1:/home /mnt/home

it will show: mount.nfs /home failed, reason given by server: Permission denied

but when I try to mount my /media directory from the server like:

mount 192.168.104.1:/media /mnt/media

it will show: mount point /mnt/media does not exist.

But my /media directory exists on my server.
Does anyone know what's going on? Do I have to change the /home directory permission or what?

Plus,I checked an article here
http://nfs.sourceforge.net/nfs-howto/ar01s07.html
ther is one reason mentioned for causing permission denied,and the author said that I might also look at the file /var/lib/nfs/xtab for an unabridged list of how all the active export options are set.If they are not, then you have not re-exported properly.
But I've exported the directories from my server successfully,why does that permission problem happen again?

Welcome to Linux, sounds like permission problems to me. I got similar errors until I figured it out as permission issues and made my fstab (I auto mount them) have these parameters on the line for the NFS folder I was mounting:

192.168.1.51:/shared /home/netdrive nfs bg,user,users,suid,rw,exec,intr,wsize=32768,rsize=32768 0 0
192.168.1.51:/var/www /home/webdev nfs bg,user,users,suid,rw,exec,intr,wsize=32768,rsize=32768 0 0

The key one you need is user or users option on the line and others like exec, suid, rw etc depending on your requirements..bg is background mounting in case not there during start up...

Here is a decent link on the NFS client setup options, it goes over cmd line entry approach too.
http://www.redhat.com/docs/manuals/l...nt-config.html

Make sure you own/have permissions for the media directory your trying to mount to. Also make sure you have permissions on the folders your are mounting from the other system. Your exports file looks ok to me, so I think it is the permissions.

I'm a noob to NFS. Which are the better options

(rw,no_root_squash,sync)

or

ro,insecure,no_subtree_check,nohide,fsid=0

and in the last one with fsid=0 removed?

Here's what I now get

10.0.0.3:/nfs4exports/share1    /mnt/shares     nfs4    bg,user,users,suid,rw,exec,intr,wsize=32768,rsize=32768 0 0

If I have nfs instead of nfs4 I get the original error message. Both PCs are using FC7.

[root@Jongi-MythTV ~]# mount -a
mount: can't get address for Jongi-MythTV
[root@Jongi-MythTV ~]# ls /mnt/shares/
[root@Jongi-MythTV ~]#

Is 10.0.0.3 even on your network??? Your first post had 192.168.104.1 for your server. Might be why it can't find it.
You should be fine with just nsf as file system type
You prolly want the earlier code for your exports:
IF you are going to write files to the directory (usually a must for all /home) you will need rw option. Sync makes sure stuff is written right away, no waiting to write files
Not sure about the fsid, would have to read up on it.

You can check the following thread on setup too.
http://www.linuxquestions.org/questi...ight=nfs+setup

the problem got solved happily,the /media problem is because I didn't create a folder, and the reason I can't mount /home is because I didn't turn off the autofs service on the server machine. Now the nfs is working. Thank you for all the people who posted here, I appreciate so much for your help. And I hope this thread can help other newbies to Linux.
