Hi,
I am linux newbie and am having some problems with
NFS hope someone could help. Here is what my problem
is.
1.My previous Administrator has set up a list of
directories that are shared from a NFS server onto a
VMS client, now I want to add another client (linux)
onto this list. So I have changed my /etc/exports file
to include the client2 and it looks like this.
/home/data/nfs
my.client1-VMS.ip.add(ro)my.client2.ip.add(ro)
/home/data/disk1/1999 my.client1-VMS.ip.add(ro)
my.client2.ip.add(ro)
/home/data/disk2/1996 my.client1-VMS.ip.add(ro)
my.client2.ip.add(ro)
/home/data/disk2/1997 my.client1-VMS.ip.add(ro)
my.client2.ip.add(ro)
/home/data/disk3/2000 my.client1-VMS.ip.add(ro)
my.client2.ip.add(ro)
/home/data/disk4/1998 my.client1-VMS.ip.add(ro)
my.client2.ip.add(ro)
�All the directories belong to the user �data� and the
group �uvi� I have changed them to be owned by root
both the user and group belongs to root now.
2. You have tied down the /etc/sysconfig/ipchains and
/etc/hosts.allow , I have changed them to look like
this now.

�sshd: my.sub.domain.
portmap: my.client1-VMS.ip.add my.client2.ip.add
nfsd: my.client1-VMS.ip.add my.client2.ip.add
rpc.mountd: my.client1-VMS.ip.add my.client2.ip.add
in.ftpd: my.client1-VMS.ip.add my.client2.ip.add
3.Did an NFS restart on the NFS server machine.
4. On the client machine I use the following command.
Mount �tnfs my.nfs-server.ip.add:/home/data/nfs
/home/data/nfs
�I have created the same directory structure on the
client also.
5.I can mount it without problems but when I try a
simple command like �ls� my system hangs up.
6.I have created some new directories for test
purposes and I can mount them and view their contents
without any problems. But the old ones I am not able
to mount them.
Could you suggest what I am doing wrong or what I have
missed?
thanks,
Chakri.
