I used iptables and blocked port number 21 all ips other than my ip and 126.96.36.199 which is ftp.redhat.com. But i am getting these error messages.
Nov 12 11:46:30 Server yum-updatesd-helper: error getting update info: failed to retrieve repodata/primary.xml.gz from rhel-i386
-server-5 error was [Errno -1] Metadata file does not match checksum
Nov 12 13:46:12 Server yum-updatesd-helper: error getting update info: Cannot retrieve repository metadata (repomd.xml) for repository: rhel-i386-server-5. Please verify its path and try again
How do i trouble shoot this? Thank you.
