I think you just summed up OS Development.

At least for me, network programming is harder than OS development. It (including a server and a browser) is a high-priority for my OS nonetheless.

I'm still thinking about how I'm going to implement networking... it's not high on my priority list, but I want to make sure that I get it right when I do it... I'll probably start with client-side stuff though (like a web browser, email client, etc.) rather than server stuff.

You have to start with a range of NIC drivers and a TCP/IP stack. That's the difficult part; everything else is fairly routine programming.

When you put it that way, I'm kinda wondering why it took me like 6 months to get my first hello world response on a single VirtIO virtual network card.

EDIT: Make that 18 months... Man how time flies when you are reading specifications....

I'm guessing it's because you were doing the difficult part.

If it takes you 6 (or 18) months to program a simple web server or client on an existing OS, such as Linux, I can only answer what my Mathematics professor said when asked a question (which we all thought was pretty difficult): "Mr ______, have you ever thought of taking up plumbing for a living?".

I started writing a network stack on the bus during my commute. It seemed like a better use of time than sitting there bored.

I didn't have it running on my OS. Just a bunch of vtys and vim, and me typing out a whole lot of C. At best I'd see how it handles various captured and artificial input with userspace testing -- capture a real world packet in Wireshark, feed it into a test program for the stack, capture the output, toss it back into Wireshark, see if it looks right compared to a real world response.

Thanks for letting me know, had the permissions on the file wrong (oops) Should work now.

I'll try it now.

Maybe you should host it on your own OS rather .

Haha, well given my OS doesn't have permissions at all, that might work
