Shortening Network timeout on Boot...

Hi guys,

This is probably a simple question but for the life of me I can't figure it out.

How do I shorten the default timeout for my ethernet card on boot? I have Ubuntu Hoary installed on my Toshiba A30 laptop, but when I turn it on without a connection plugged in, it takes about 60 seconds before it fails and continues on it's way.

It works fine when there is a cable and connection present, but I often use my laptop with a connection and it's frustrating waiting for something I know it won't find.

Also, Fedora Core 3 had a GUI for enabling and disabling services easily (called "Services" in the GNOME menu) - Could someone please tell me how I can get it on Ubuntu or what it was called?

Many Thanks,

Your ethernet

timeout is not an OS specific issue- this is something that you would set in BIOS. Go ahead and google how to change BIOS settings for your particular machine

[for instance, my Dell requires a Ctrl-Alt-Enter during the very first stage of boot to enter this... my Syntax motherboard requires me to hold down Delete in a similar way]

and somewhere in there there should be a way to change this (although you may have to turn off 'boot over LAN/ethernet adapter completely)

BTW don't change anything else in there unless you really know what you are doing. As a side note, I might say something about the fact that ONE of my machines still tries to do this even if I set BIOS not to...

On my Dell there is a place where I can set up which devices I wish to be able to boot from, and no matter how many times I take the etherboot off of the list, it still ends up back in there somehow. How, I do not know. It is not a problem with the battery- this thing keeps the time in a way that is competitive with any of the best watches I have ever owned.

If after going into your BIOS and changing this (or similar) etherboot setting, you still have some sort of undesireable problem, I am sorry that this did not take care of that. You are not alone in this

It has nothing to do with the BIOS at all - you misunderstood me.

It is not "Boot from LAN" like you would boot from a HDD or a CDROM, it IS an OS specific issue, because when I was using Fedora Core 3 I fixed it, but I can't for the life of me remember how.

When LINUX is booting and AFTER Grub has passed, it detects my hardware, goes through the standard boot procedure, mounting filesystems etc, but when it gets to "Configuring Network Interfaces" it pauses for 60 seconds when no cable is plugged in.

Additionally because of that, I also get a smaller pause when LINUX tries to contact an NTP time server, because there is no connection to my network.

Like I said before, it works fine when a network cable is plugged in, but it is nothing whatsoever to do with "Boot from LAN" or "Wake on LAN".

Many Thanks,
