I am using Hathway cable internet where they bind your ip settings to your pc. If I unplug the lan cable from the pc and plug it into my laptop, I cannot browse. They are using some sort of dhcp with a static ip (I know that sounds funny - but that's what they say).
I do face this a lot of times too. I have tried to ask them many times as to the logic of the same and if they could disable it in my case. But, it all fell on deaf ears.
When I called the helpdesk, they said what I need to do is release the ip from my machine and then renew it on my laptop. something like ipcfg release and then ipcfg renew. The guy obviously has no clue how to do it in linux.
What would be the equivalent in linux. I am using debian 5 and kubuntu 9.04 on the two machines.
There would be quite a few ways. If you're using NetworkManager, disconnect from the wired connection or right click and disable networking. If you're using dhclient, you are looking at the -r switch dhclient -r eth0, for example. Here's the snippet from the manpage " The client normally doesn’t release the current lease as it is not required by the DHCP protocol. Some cable ISPs require their clients to notify the server if they wish to release an assigned IP address. The -r flag explicitly releases the current lease, and once the lease has been released, the client exits."
In case you want more specific help, you will need to let us know as to which tool you are using to connect.
