Before configuring network card we must check loopback (IP address 127.0.0.1) is working. 3. Even if the compute is not connected to outside network internet network configuration is required for some applications. This address is known as loopback device, and its IP address is 127.0.0.1 4. To check loopback device is configured or not, we use ‘ifconfig’ command it shows a device called ‘lo’ with the address 127.0.0.1, if this device and address is not shown there then loopback is not configured. 5. To configure it we can use command ifconfig lo 127.0.0.1 after that we need to use the ‘route’ command to give system a little more information about this interface for this ‘route add –net 127.0.0.0’ command is used, after this loopback is setup. 6. To configure a network card we will use ifconfig co...

NFS client needs the portmapper running in order to process and route RPC calls and returns from the server to the appropriate port and programs. 3. We can ensure portmapper is running or not by using following command: #service portmap status 4. If portmapper is not running then it’ll show us portmapper is stopped to start portmapper we’ll use following command: #service portmap start 5. Mounting can be done using following commands: For example we wants to mount /media from the server configured at the end then we’ll execute following commands: #mount –t nfs 192.168.166.5:/media /media 6. If user wish, he/she can specify client mount options using mounts arguments as; #mount –t nfs 192.168.166.5:/media /media -o resize=8292,wsize=8192, hard, nolock 7. Following are t...
