I use linux for C++ only. If I get broadband do I have to have an ISP, if I do
can anyone suggest a real one compatible with Linux. Thanks.

O_O

The only compatibility issue with linux and broadband is the ethernet card you use to connect with thru the router. If i'm understanding you correctly.

As far as a Isp...yep you have to have a isp...its the company that you are paying for the connection with that is your isp. Without a isp you can't connect to the internet.

You're broadband provider is your ISP.

depending on how you hook it up, you may rnun into problems. if you use a storebought router, all you need to do is plug the linux box in and make sure it has a ip address set.

now if you are going to use your linux box AS the router, this is where things may get complicated.
for starters:
- make sure the dsl or cable modem supports ethernet so it can be plugged into the network card on the linux box
- if it does not support ethernet, hopefully it will support usb, and then you will need to do some research to get it working.

i myself have never set up my linux box as the router, but i have messed around with some of the settings.
if you have a spare box, i would recomend using smoothwall [smoothwall.org] as a basic linux router, if not, use the linux documentation project [tldp.org] for any help.

to keep it simple, get a hardware router from the store and everything should be as simple as plugging in the wires (After you set up the router, which is a no brainer also)
