Linux01 basics

  1. 1. What Linux is? Linux itself is just a kernel (1)
  2. 2. Linux can be configured as a networked workstation a DNS server, a DHCP server, a web server, a mail server, a file and print server, database server, a firewall, a gateway router and many more... (2)
  3. 3. User will learn the true meaning of Linux, which is a network operating system or server system. The first thing you should learn about networking is ip addresses. A server and a client computer must have an ip address so that it can be reach in network environment. 3 (3)
  4. 4. Linux server can serves networking 365 days a year without any problem. Linux is a very stable and secure network operating system when properly configured and maintained. All that starts with setting up a network card and configure an ip address for the server. 4 (4)
  5. 5. The Linux networking - Installing Ethernet card tutorial is a guide on how to install Ethernet card in Linux computer. 5 (5)
  6. 6. Ethernet card or more commonly known as network interface card is a required component if you want to connect to the network. Ethernet card is available in two version which are the PCI slot or the older ISA card. However, nowadays computer always comes with integrated Ethernet with motherboard. (ISA = Industry Standard Architecture) (PCI = Peripheral Component Interconnect) 6 (6)

  9. 9. Installing an Ethernet card [1] 1. Power off your computer. 2. Open computer casing and Install your PCI Ethernet card in an available PCI expansion slot (an ISA card into ISA slot). 3. Close computer casing and plug in network cable into the Ethernet port and the other end into the router port (cat5 cable with RJ-45 socket). 9 (9)

  15. 15. Installing an Ethernet card [2] 4. Power on your computer. 5. Normally Linux will detect the Ethernet card and load appropriate kernel when you boot up the system. However if Linux doesn't detect it, you must manually configure the Etehrnet card by loading appropriate module using modprobe. 15 (15)
  16. 16. Installing an Ethernet card [2] 6. After Linux has finished boot up, check /etc/modprobe.conf (Slackware /etc/modprobe.d/modprobe.conf) that appropriate kernel has been loaded. 7. Type less /etc/modprobe.conf and verify that the alias eth0 has been created (and eth1 if you installed second Ethernet card). 16 (16)
  17. 17. Installing an Ethernet card [2] 6. Type less /etc/modprobe.conf and verify that the alias eth0 has been created (and eth1 if you installed second Ethernet card). If not then you may need to manually edit this file and create the appropriate alias. If you don’t, you’ll lose your networking configuration when the system reboots. you 're done, then it time to configure the ip address for the Ethernet card 17 (17)
