(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.

(1) not sure what this is..... Can you give me more info and clarity on the issue?
(2)try to find out what has what by using lsof
(3)hostname does not update other computer's name resolution process.
You will have to either manually edit DNS server's entry OR client's /etc/hosts file.....

Hope this helps..

Thanks for your caring.

> (1) not sure what this is..... Can you give me more info and clarity on the issue?
/etc/exports entry was:

/ 192.168.11.0/24(ro,no_root_squash)

Server's entire file system, including /mnt/windows, could be accessible from the client.

I neve used lsof command. What's the point we shoud see in it?

What is the 'DNS server's entry' ?

1..try
/mnt/windows 192.168.11.*(rw)
in your exports. some servers refuse to export / no_root_squash'd. quite dangerious to...

2..please post (from the server):
"exportfs; mount"

3..machine to ip names are in /etc/hosts. they have to be the same on your network machines. /etc/nsswitch.conf should give you a line "hosts: files dns", so first the hosts-file will be tried to resolve a hostname and the nameserver in /etc/resolve will be tried.
if you have a dns-server set up on your network (likely bind/named) you'll have to edit your zone files there. if you don't know what i'm talking about just edit hosts.
