zhaozhuo,

    Redhat 9.0 has very tight security features.
Until you isolate the problem:
1. Try temporarily turn set security level to off.
2. Try temporarily removing /etc/hosts.allow and
   hosts.deny.
Then try:
3. Make sure that nfs is set to automatically start
   on bootup:  (you need nfslock as well as nfs)
   > chkconfig --list | grep nfs
   nfs             0:off   1:off   2:on    3:on    4:on    5:on    6:off
   nfslock         0:off   1:off   2:on    3:on    4:on    5:on    6:off
4. Make sure that portmap is set to automatically start
   on bootup:
    > chkconfig --list | grep portmap
    portmap         0:off   1:off   2:off   3:on    4:on    5:on    6:off

     Attached are my notes on NFS mounting.

Mounting NFS Files     July 25, 2003     [email protected]
Redhat Linux 9.0
======================================================================

======================================================================
Mounting NFS Files Errors:
======================================================================

Must have network connection:
  [root@bra-pc etc]# mount xcelsior:/home0 /mnt
  mount: RPC: Remote system error - No route to host

hostnames must be on the same network.
  [root@bra-pc etc]# mount xcelsior-2:/home0 /mnt
  mount: RPC: Timed out


  [root@bra-pc-20 root]# mount bra-pc-2:/home0 /mnt
  mount: RPC: Remote system error - Connection refused


  xcelsior ~/ > runas mount xcelsior:/home0 /mnt/floppy
  mount: xcelsior:/home0 failed, reason given by server: Permission denied
  xcelsior ~/ >



======================================================================
REQUIREMENTS for EXPORTING and MOUNTING FILE SYSTEMS
     NFS must be installed.
     hosts must be on the same network (No routing).
======================================================================

On host that is EXPORTING file system/s:

/etc/hosts.allow
        Example:
        portmap: 192.168.14.220, 192.168.14.221, 192.168.14.222: ALLOW
or
        No /etc/hosts.allow & No /etc/hosts.deny


Security Level
        [
        High
        Customize
        Trusted Devices: eth0   (192.168.14.x) or Ethernet Port used.
        ]
or
        [No firewall]

> chkconfig --list | grep portmap
portmap         0:off   1:off   2:off   3:on    4:on    5:on    6:off

> chkconfig --list | grep nfs
nfs             0:off   1:off   2:on    3:on    4:on    5:on    6:off
nfslock         0:off   1:off   2:on    3:on    4:on    5:on    6:off




======================================================================

On host that is MOUNTING file system/s:

Security Level
        [
        High
        Customize
        Trusted Devices: eth0   (192.168.14.x) or Ethernet Port used.
        ]
or
        [No firewall]

> chkconfig --list | grep portmap
portmap         0:off   1:off   2:off   3:on    4:on    5:on    6:off

> chkconfig --list | grep nfs
nfs             0:off   1:off   2:on    3:on    4:on    5:on    6:off
nfslock         0:off   1:off   2:on    3:on    4:on    5:on    6:off
