NAD710 - Introduction to Networks - Using Linux
Objective
Use the following commands to collect system information and network settings on a Linux Machine:
- hostname
- uname
- /sbin/ifconfig
- /sbin/route
- /sbin/lspci
- /sbin/lsmod
- /sbin/modinfo
Background Information
A computer must have the proper network settigns in order to communicate with other computers either on a local area network or on the Internet. The procedure below could be used to collect the following network settings and system information on a Linux machine:
- MAC Address
- IP address
- Network Mask
- Broadcast address
- Network address
- IP address(es) of the gateway(s)
- hostname
- list of PCI device
- Network device driver
- Linux Kernel information
Follow the procedure on matrix.senecac.on.ca and your own Fedora Core machine to collete those network settings and system information.
Procedure
- On any Linux machine with Internet connection, run the ssh client to login to matrix.senecac.on.ca using your email account and password:
[studen@fc9 student]$ssh student@matrix.senecac.on.ca Password: Have a lot of fun... student@matrix:~>
- Type the command
uname -a
- Use the command "man uname" to display the manual page for the command "uname" and use it to decode the output of the "uname" command. You should record the output of the "uname" command for later use.
- Type the following command to display the host name of the machine you are on:
hostname
- Type the command /sbin/lspci to display all the PCI devices detected by the Linux kernel. Record the output, especially look for the line that contains the words "Ethernet controller".
/sbin/lspci 00:00.0 Host bridge: Intel Corporation 82845 845 (Brookdale) Chipset Host Bridge (rev 04) 00:01.0 PCI bridge: Intel Corporation 82845 845 (Brookdale) Chipset AGP Bridge (rev 04) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 05) 00:1f.0 ISA bridge: Intel Corporation 82801BA ISA Bridge (LPC) (rev 05) ...
- Each piece of periphal hardware need a program (device driver) to control it. Most of the hardware device drivers are implemented on Linux as loadable kernel modules. The command /sbin/lsmod can be used to display all currently loaded kernel modules (i.e. hardware device drivers).
/sbin/lsmod Module ... Size Used by loop 20488 0 dm_mod 60184 0 usbhid 52192 0 e100 40456 0 mii 9600 1 e100 i2c_i801 11660 0 i2c_core 25216 1 i2c_i801 ...
- The first column on the output of the /sbin/lsmod command is the module name. You can obtain more information about each loadable kernel module withe the command /sbin/modinfo:
raymond@matrix:~> /sbin/modinfo mii filename: /lib/modules/2.6.18.8-0.5-default/kernel/drivers/net/mii.ko author: Jeff Garzik <jgarzik@pobox.com> description: MII hardware support library license: GPL vermagic: 2.6.18.8-0.5-default SMP mod_unload 586 REGPARM gcc-4.1 supported: yes depends: srcversion: 16DCEDEE4B5629C222C352D
- Try the command on each of the module listed and determine which one is the device driver for the network interface card. Record the location (filename) of the device driver of the network interface card.
