As discussed on the page, NetworkManager<\/a>, the NetworkManager makes setup and configuration of network connections very easy for non-technical users. It can be very useful in a mobile environment where a laptop may move from being connected by hard wired Ethernet cable, to a connection via wireless, to being connected over a WiMax connection. Those types of dynamic transitions are made extremely easy by the NetworkManager.<\/p>\n

That easy transition can cause issues when using multiple NICs in a more static environment. I have found that NetworkManager cannot always determine the correct NICs to bring up on a\u00a0 couple of my systems that I use for routers and which have four NICs each. In fact, sometimes no connectivity at all is extant after a reboot. This is not such a good thing in the event that a remote reboot is required. Under such conditions it may be desirable to disable the Network Manager and return control of network initialization to the older network init scripts.<\/p>\n

Both the NetworkManager and the older network init scripts are controlled by the chkconfig command. Be sure to both turn off the NetworkManager and turn on network using the commands:<\/p>\n

\n
chkconfig NetworkManager off\r\nservice NetworkManager stop\r\nchkconfig network on\r\nservice network restart<\/pre>\n<\/blockquote>\n
These commands transfer network startup control back to the older init scripts and turn off the dynamic NetworkManager. And yes, the commands for NetworkManager do contain capital letters.<\/p>\n
You must also be sure that the network configuration files, \/etc\/sysconfig\/network-scripts\/ifcfg-<NIC Name> are properly configured. See the sample on the NetworkManager<\/a> page and a more complete explanation of these files on the Configuring Network Interface Cards (NIC) page.<\/p>\n","protected":false},"excerpt":{"rendered":"
