In a multi-NIC environment, the choice of default routing often becomes a headache.This article speaks about Red Hat's Linux about/etc/sysconfig/network-scripts in the default routing policy used.In/etc/sysconfig/network-scripts, there is an option in ifcfg-xxx that is defroute. The interface is set as the default route, as described in the documentation.And by the author experiment, even if you want to int
Configuration requirements:
In an enterprise environment, network administrators often have the need to improve the productivity of their employees:
Ⅰ. Only allow employees to log on to work QQ and MSN;
Ⅱ. Restrict employees to use common downloading software, stock software, video software and games;
Ⅲ. Check the behavior record of the employee surfing the Internet at irregular intervals.

Linux Network-related profiles Linux systems generally fall into two main categories:1, Redhat series: Redhat, Centos, fedora, etc.;2, Debian series: Debian, Ubuntu and so on. In Linux systems, TCPIP network is configured through a number of text files, you need to configure these files to network, the following for the Linux two major types of systems in the bas
Now it's time to put all of the previous theoretical knowledge into practice. Next, we will explore:
