We just got DELL R920 and installed Centos 6.5 on it.? After installation, network not function.? We manually enter IP address, gateway and netmark on "em1".? we also do following: 1. startup NetworkManager 2. /etc/sysconfig/network-scripts/ifcfg-em1? ==> NM_CONTROOLED=yes I tried to startup network and get error message: Bring up interface em1: connection activation failed Device not managed by NetworkManager or unavailable. Any ideal? Thanks.

Fix it. Also, how are you manually entering the ip/gateway and netmask? Are you putting them in the config as well? It would help to see the config to know where you might have mistakes. -- Jim Perrin The CentOS Project | http://www.centos.org twitter: @BitIntegrity | GPG Key: FA09AD77
