Hello, I suspect this probably has been reported, but just in case it has not. The download servers ftp, ftp1 and ftp2 has been unreachable from most of today. It appears their DNS entries have been withdrawn. [root@apps2 install]# nslookup ftp.scientificlinux.org ;; connection timed out; no servers could be reached [root@apps2 install]# ping -c 1 ftp1.scientificlinux.org ping: unknown host ftp1.scientificlinux.org<ftp://ftp1.scientificlinux.org> Any idea what is happening here? Many thanks. Regards, Peter Chiu STFC Rutherford Appleton Laboratory RAL Space Department Building R25, Room 2.02 Harwell Oxford Didcot OXON OX11 0QX UK -- Scanned by iCritical.
