NFS newbie troubles

[hiwa]

(1) Accessing Windows partition on the NFS server from client
NFS client can't access /mnt/windows dirs and files on the NFS server.

(2) NFS lock
Even after the client unmounts NFS mount point, we can't access files on
the server from THE server itself.

(3) NFS client don't access new hostname of the server
After changing the server host name by hostname command, the mount command
line on the client can't recognize the new host name. Only server's IP
address works on the command line:

mount -t nfs 192.168.11.3:/pub /nfs

I'd like to know the causes/reasons of above phenomenon and workarounds for
those.

Thanks in advance.

Can normal users on the server access /mnt/windows? By default, requests from NFS clients with UID 0 (root) are treated as requests from "nobody." So if "nobody" on the server can't access /mnt/windows, neither can your clients.

You either need to add umask=000 to the windows partition's options in /etc/fstab, or put no_root_squash in /etc/exports (which lessens your security and probably is not the best solution).

.... error message?

That's because your client has no way of knowing the server's hostname. You either need to have it defined in the clients' /etc/hosts, or set up a DNS server.

Have fun,

Yes I did no_root_squash in the /etc/exports entry:

/ 192.168.11.0/24(ro,no_root_squash)

.... error message?
No message. Everyday mundane programs such as editor, image viewer etc. couldn't open any file.

set up a DNS server
How? Could you give pointer?

Post your fstab.

That's _very_ odd.

Here is the DNS howto:

I am running dnsmasq... it was fairly easy to set up.

Check /var/log/messages, almost everything system related gets logged there. I have tons of NFS messages in mine from when my NFS server crashed.
