 Posted: Fri Jun 03, 2005 1:39 am Post subject: Obtaining a new IP[SOLVED] |
 |
|
I need to obtain a new non-specific IP for my eth0. I've tried various commands non of them seem to stick because as soon as I /etc/init.d/net.eth0 restart I just get my old IP back.
Basically I'm asking for the Linux equivalent of ipconfig /release ipconfig /renew

First, edit your /etc/conf.d/net to contain this:
Then you can do a /etc/init.d/net.eth0 restart
If you were previously getting a dhcp address, then you will probobly find that you are still getting the same one. This is because your dhcp server is maintaining your lease for a given period of time. ISPs are usually a couple of hours, but some can be a week or more. If that is the case then you will have to leave your box off for a couple of days before trying to get a new address.
Of course, if you can't wait then you can stick in a new NIC. A new MAC address will definately get you a new IP Address.

Can you be more specific? Can I see your ifconfig? "non-specific", how do you mean? Why do you need a new one?

That should restart your DHCP. I find I get the same IP every time as well; I've never did mind though.

Your router contains your DHCP leases (I think). Your best bet is to:
1) /etc/init.d/net.eth0 stop
2) Go into your router config via a web-browser and click the DHCP Release and then DHCP Rnew buttons.
3) /etc/init.d/net.eth0 start
I'll be glad to help further and will check back in a few.
Peace,

Its spoofing time!
| Code: | | ifconfig eth0 hw ether 11:12:13:14:15:16 |
That code, or something or other, should get yor mac changed  . Check the ifconfig man page for more info.
