If everyone is running STANDARD CENTOS there should be *no* problems updating to the latest C 6.8 version. (1) Save one complete installation. (2) Install it on a spare machine. (3) Change /etc/sysconfig/network-scripts/ifcfg-eth0 if necessary. (4) Do a: yum update (5) Test the applications (6) Wait a few weeks and if still no problems, then upgrade the others. -- Regards, Paul. England, EU. England's place is in the European Union.
