Test Network Connections

Introduction:

Now we have a fully configured and connected Linux served home network. Let's make sure it all works...

Aim:

Test the network.

Requirements:

You have Linux installed and configured, the network is physically connected and you have rebooted both the server and PC.

Procedure:

Server Tests:

• Log in as root.
• Check ping:
• We are going to check that the server can 'see' all the devices on the network. If it can't do this, we are on a hiding to nothing. In the Terminal, type ping and either the IP address of the device or its name. Ping replies with a list of ping statistics about 1 second apart. As long as you get 'time=n.nnn ms' at the end of each of these lines, we are good at the moment. There is an example on this post. Type Ctrl-C to stop the listing.
• # ping 192.168.0.2 (self by IP)
• # ping lisa (self by name)
• # ping lisa.steveroach.org (self by full name)
• # ping 192.168.0.3 (the PC)
• # ping homer
• # ping homer.steveroach.org
• # ping 10.1.1.1 (the DNS IP)
• # ifconfig eth0
• Get the IP address of the ADSL modem, i.e. the one right after 'inet addr:'
• # ping the IP you just got.

PC Tests:

• Open a DOS window; -Start-, -Run-, Open: cmd, [OK]
  
• # ping 192.168.0.2
  
• # ping lisa
• # ping lisa.steveroach.org
• # ping 192.168.0.3
• # ping homer
• # ping homer.steveroach.org
• # ping 10.1.1.1
• # ping the IP you got for the ADSL modem.
