I googled to see how I might restart the network interface in CentOS. I initially tried before googling: sudo service network restart I noticed that only the loopback interface was restarted. To confirm this I did: service network stop and then did ifconfig and the loopback info was gone. I then found ifconfig eth0 up/down and tried those and that did what I is was looking for. Why doesn't "service network restart" restart all interfaces? Thanks, -wes
