Not that I have a solution for the above issue, but is worth underlying that it is better to make sure createrepo is installed since the beginning.

you have 2 option:
1. make sure your gpg is right.
2. disable gpg check with gpgcheck=0

gud lak.. ;)

yes right, when yum is configured locally it is working. how to do that on the client machine.

client is nfs client. how will i configure yum repository now.
becos it is giving error if i configured in the same way. problem is it is unable to read /mnt/iso/1 directory.

error downloading packages kernel-headers-2.6.18-194: failure: 1/Server/kernel-headers…rpm from my_iso_repository: errno 256 no more mirrors to try.

when I tried to install the software through
yum –enablerepo=server install package name

me receiving the same mentioned above error.

setting up a software-repro by using yum and a software-repro? Well man, I don’t know what you are smoking, but I like to ask you if you mind to share it …

vi /etc/yum.repository.d/iso.repo
[My-ISO-Repositary]
baseurl=file:///data/iso
enabled=1

when I tried to install the software thorugh
yum –enablerepo=iso.repo install bind

[root@server ~]# yum –enablerepo=iso.repo install bind
Loaded plugins: fastestmirror
Repository ‘My-ISO-Repositary’ is missing name in configuration, using id

Error getting repository data for iso.repo, repository not found
[root@server ~]#

Kinldly help me solve this problem
