So, i fixed this by manually deleting the .rpm file from /var/www/cobbler/repo_mirror/ and then I re-executed the cobbler reposync. This put the proper RPM into the directory. On the client I did a yum clean all and a yum install iperf and it worked. -- Christopher Dale | President and Forum Moderator mobile: 540-903-1775 | email: christopher.dale(a)colloquium.co web: http://www.colloquium.co | twitter: @colloquiumco<http://twitter.com/colloquiumco> | identica: @colloquiumco <http://identi.ca/colloquiumco>
