I'm trying out ubuntu, and it happily sees my dlink wireless card as ath0.
I manually set up the interface, but when I try and request an IP from the network by using "pump" I can an error.

So the ubuntu hoary I have doesn't have pump. Is there any other way to request the IP so I can get on the internet?

dhcpcd, dhclient or dhcpxd should be there and will replace pump just fine.

Thank you acid.

I must note that as so often happens when I submit a question to LQ my determination to solve it increases. In many cases, I end up solving it myself.

So, in fact, I had checked out dhclient, and it worked, though not the first time. Only the second, which is pretty unusual. But anyhow, I'm reading your reply now and thank you anyway. Hard not to do, 'cos I know of the immense work you put into LQ and even if you were say "Please repeat your question" I'd still thank you :-D

There's room to ask why a few altewrnative tothe same function exist. Why dhclient *and* pump?

so often the way... no matter nice to be appreciated!

quite why there are sooo many clients i'm not sure... but development of multiple clients does encourage innovation etc... not that dhcp is exactly a seething bedrock or anything these days. each client does do things a little differently though, such as being able to explicitly provide hostnames to the dhcp servers, or ways to disable or enable to automatic configuration of local files, like resolv.conf
