Hi All,           In some scenarios, we want to find out the performance factors of our NIC card attached. Because, if we are working on network for doing some work, then surely we need to transfer data from one system to other. Maximum performance depends on the configuration of NIC Card we are using.                                       So here are some command Line tools in Linux to find out useful info. 1.) ethtool 2.) mii-tool 3.) dmesg 1.) ethtool: [root@server199 ~]# ethtool eth1 Settings for eth1:         Supported ports: [ TP ]         Supported link modes:   10baseT/Half 10baseT/Full                        ...

Hi Friends,                  Here I am going to post the whole process about the Interaction between DHCP Client and DHCP Server(How a DHCP client communicate with DHCP Server to get an IP Address).                          DHCP is a very common protocol and we often here about it. DHCP is much more complex than it looks. DHCP IP address assignment process goes through a few steps explained in this article.             DHCP stands for Dynamic Host Configuration Protocol and is used to automatically assign IP configuration to hosts connecting to a network. The Dynamic Host Configuration Protocol (DHCP) provides a framework for passing configuration information to hosts on a TCPIP network. DHCP is based on the Bootstrap Protocol (BOO...
