RHEL5 installation through NFS

[nach p]

Hello

I am trying 2 install RHEL5 through nfs
All packages required installed to configure nfs server

[root@nachhost Desktop]# rpm -qa | grep nfs
nfs-utils-1.0.9-16.el5
nfs-utils-lib-1.0.8-7.2
system-config-nfs-1.3.23-1.el5

My ip is 10.10.127.145 and I want to install at friends place having ip 10.10.127.26.
I shared all discs rpms and readme files at /install directory at my place

[root@nachhost Desktop]# cat /etc/exports
/install 10.10.127.26(ro)

#exportfs -ar

#service nfs restart

I created bootable cd wid boot.iso file

At 10.10.127.26
inserted and continued installaton wid "linux askmethod" and selected nfs option.
Inserted all static ip values
But when I click next it show "Directory can not be mounted"

where am I missing.

thnx.

RH distros by default enables iptables FW via lokkit script.make sure u as super user flushes iptables:

~# iptables -F

and look:

~# iptables -L

yup firewall was blocking nfs and other services
now its working.

I copied all rpms and release notes to /install directory and shared on nfs.

But Now it shows

That directory doesnt seem to contain a RedHat Enterprise Linux Server installation tree.
