network configuration

[Nofriyadi Nurdam]

Marc, I thank you very much for the answer.
  
  I have tried:
  # /etc/rc.d/init.d/network restart
  
  response of redhat:
  shutting down loopback interface         [OK]
  setting network  parameters                   [OK]
  Bringing up loopback interface: arping: socket: address family not supported by protocol
  Error, some other host already uses address 127.0.01      [FAILED]
  Bringing up interface  eth0                   [OK]
  
  Response of  # ifconfig : command not found
  
  Response of # netconfig : command not found
  
  How can I know which other host uses the address 127.0.0.1
  
  Would you give any more advices, please?!
  
  Thanks in advance
  Best Regard
  Nofri

# service network stop

(that shuts down networking)   then do

# service network start  

(which should make the service start).  

Now do

#  ifconfig eth0  

and it will tell you if it is up or not.    


If eth0 is not up do 

#  ifup eth0  

and that should bring it up



Good luck
Marc

  I am a computer class teacher and have to teach how to set up RedHat9.
  But I have problem with network configuration.
  I have tried System Setting > Network.
  Under Network Configuration I find   
  - Defice: status=inactive, alias=eth0
  - Hardware: RealTek RTL-8139, SMC Ez Card
  - DNS: hostname= computer_name
  - Hosts:   127.0.0.1    computer_name localhost.localdomain localhost
  
  As I clicked the profile of device and activitated it, I became  message: You have made changes in your configuration. To activate the  network device eth0, the changes have to be saved  
  
  The message after saving: Changes are saved. You may want to restart network and network service or restart the computer.
  
  I have restarted my computer, but the network device stay inactive.
  
    Would you help me please, how to activate the network device.
  In the network there has not been DNS server. (I hope, I   could build it next time).
  
  Thanks in advance
