mount/export network file system

[ZHANG YD]

hi,
I try to export network file system from a PC 'tree'
to another pc 'frog'. The 'tree' installed with PC2,
'frog' installed with RH 9.0, both are networked under
the same domain, eg its.edu.au

here is /etc/exports script:

# export file system to frog
/home/user4 frog(rw,async,no_root_squash)

the nfs service started ok eg 
/sbin/service nfs restart
Shutting down NFS mountd:             [  OK  ]
Shutting down NFS daemon:             [  OK  ]
Shutting down NFS quotas:             [  OK  ]
Shutting down NFS services:           [  OK  ]
Starting NFS services:                [  OK  ]
Starting NFS quotas:                  [  OK  ]
Starting NFS daemon:                  [  OK  ]
Starting NFS mountd:                  [  OK  ]

the fstab line at frog is
tree:/home/user4   /mnt/tree  nfs  defaults 0 0
when I tried to mount this at frog with

mount /mnt/tree

I got a error message:

mount: RPC: Remote system error - No route to host

could sone help me fix this?

enable the nfs service on the machine tree.

You you also change the /etc/fstab line to read:
tree:/home/user4   /mnt/tree  nfs  defaults 1 2

Forgive me for not knowing the name for this icon on the gnome panel
(it's the one with a red hat).

RedHat -> System Settings -> Server Settings -> Services

You will be asked to enter roots password and it will then display a
list of services.  On the left side is a box which either has a check
mark or not in the box.  Go down the list till you find one that
says nfs, click on the box to set it to start at boot time.  At the top
of the Service configuration window is an icon that says Start, you
want to click on that icon to start the service now.

You now should be able to mount file systems from that machine.

Forgot to say that before you exit the Service configuration window,
you need to save the changes.

huh? why do you want to set the backup and fsck sequence numbers for
an nfs mounted partition? "0 0" is more normal/usual for nfs mounted
partitions.

man fstab...

The  fifth  field,  (fs_freq),  is  used  for  these filesystems by the
       dump(8) command to determine which filesystems need to be  dumped.   If
       the  fifth  field  is not present, a value of zero is returned and dump
       will assume that the filesystem does not need to be dumped.

The sixth field, (fs_passno), is used by the fsck(8) program to  deter-
       mine the order in which filesystem checks are done at reboot time.  The
       root filesystem should be specified with a fs_passno of  1,  and  other
       filesystems  should  have a fs_passno of 2.  Filesystems within a drive
       will be checked sequentially, but filesystems on different drives  will
       be  checked  at  the  same time to utilize parallelism available in the
       hardware.  If the sixth field is not present or zero, a value  of  zero
       is  returned  and fsck will assume that the filesystem does not need to
       be checked.

frankly, this does not bother me much. Problem is the
nfs export still does not working. Some suggested that
to do someting on iptables or firewall setting. I have
not get insides to fix it. any hints on iptables is
welcomeed.

Make sure you have either configured iptables to let nfs through or
disable iptables.  As a test disable iptables on tree then retry the nfs
mount.  If that works then you need to setup iptables to permit nfs
access on tree.

If that did not work then make sure frog does not have iptables enabled
and run the same test.

Also make sure you can ping each system from the other to eliminate
basic network problems.  (ie. make sure each server is listed in the
others /etc/hosts file or in DNS)
