how to remove network configuration from boot up

[shariharan301]

hi. Am using Ubuntu 12.04 Desktop LTS.

when i boot my ubuntu,following configuration msg is appear.
"wait for network configuration" & " waiting for 60 more seconds for network configuration".

After booting system without LAN connection. Network notification icon is not appearing.?

can u help pls..?

Thanks in Advance...

Finally i got the result..

To skip the network configuration time while system starting.. do the following steps.

1. Type the cmd in terminal.
"gksudo gedit /etc/init/failsafe.conf" (suppose access permission is not available. pls provide it.)

2. After the open the file. make some changes wat i mention.

on line 26 -> change "sleep 20" to "sleep 5".
on line 32 -> comment the sleep time using '#'. (eg: #sleep 40)
on line 35 -> comment the sleep time using '#'. (eg: #sleep 59)

then save it. and restart.


without LAN Cable activate Network Manager.
No need to connect LAN Cable, while system boot. easy way to config network manager.

on File system-> etc -> network -> Interfaces

edit the "interface" file.. using following content to replace the existing content.

//

auto lo
iface lo inet loopback

//

This is working for me..

You are getting that message because something is wrong with your network configuration. A better approach is to look for what is wrong and try to fix it rather than get rid of the message!

Try:

ifconfig -a

Bring your interfaces down one by one with:

ifconfig <interface> down

Reset the network:

/etc/init.d/networking reset

Dont forget to bring your interfaces up one by one

ifconfig <interface> up

Almost certainly you will see some error, like a misconfigured interface.

As far as I could see, the message and the delay will occur when the interface eth0 is in the /etc/network/interfaces file and the cable is not connected.

My solution was just to leave the loopback interface there and let NetworkManager handle any other interface.

I had no time to take a closer look...
