I hav done research on the forum about raw sockets but none of theme show concrete statements of why sockets dont work or even any example of codes that people have tried.
Mind posting what you have tried?

I'd run the above code and try to ping the PSP from my computer. Using normal packets would allow me to see the packets (not raw). Using raw sockets, I'd get absolutely nothing.

Yeah, plain sockets with regular connectivity. If you want that in B2, you could write a special version of FireFox (or whatever) that used a special command to use the PSP sockets to communicate. That's UPPER LEVEL networking. OSes provide the LOWER LEVEL. In the case of the PSP, that's Sony's socket code and libs. In the Mac, that's MacOS. MacOS deals with packets at a level lower than regular sockets. So does Windows, or Amiga TCP, or any OS. The OS handles the low level while the applications use the high level. If you're emulating an OS, you're stuck trying to figure out how to handle that low level when all you have is the higher levels. That's where raw sockets come in - it gives applications the ability to dip down into those low levels and do things they otherwise couldn't.dennis96411 wrote:Doesn't PSPKVM use sockets for internet connectivity?
when pinging the psp with the pc should I be seing anything on the psp happen?
On the comp it says it recved them but theres nothing that prints on the psp
and what does it recv from?
length = recvfrom(sock, RecvBuf, 1514, 0, (struct sockaddr *)&from, &from_len);

Exactly. If it were working, you'd see prints about the packets. Raw sockets just doesn't seem available... at least not to user-mode apps. I haven't tried that same thing in kernel-mode yet. The computer saying the PSP received them shows the AP is connected and the networking properly initialized - so the PSP is getting the packets... but the user app isn't. The example is a pretty standard rawsockets example from the PC for simply dumping info about all the packets that come in.Gaby_64 wrote:when pinging the psp with the pc should I be seing anything on the psp happen?

Why is it that when I try to set it to nonblock in my app it says 109(ENOPROTOOPT)
EDIT1:
I dont think it works in kernel mode, it fails to initialize the network and freezes when trying to create a socket
EDIT2:
and the psp doesnt display anything because recvfrom fails
Error = ffffffff, -1
and from is not defined? Should that be the routers IP?
recvfrom(sock, RecvBuf, 1514, 0, (struct sockaddr *)&from, &from_len);
EDIT3:
found my answer here and some interesting info
http://msdn.microsoft.com/en-us/library ... S.85).aspx
also why do you put +1
select(sock+1, &readfd, NULL, NULL, &timeout)
EDIT4:
the sceNetInetRecvfrom function freezeson psp (I wanted to use it to be able to get the error number, is there a way to get error number from the non sce functions?)
sorry for all the questions butI still believe it is possible
EDIT5:
here is a screenshot of what I got so far:
as you can see recvfrom fails, EBADF, /* Bad file number */
but what does that mean?
EDIT6:
tested with sock_stream and sock_dgram and recvfrom returns the same results
so this could only be a problem with recvfrom and not that raw_sockets are not posible on psp

Like I said, I haven't tried kernel mode. You may have to change the init around as the current init is using user functions, not kernel functions.Gaby_64 wrote:Why is it that when I try to set it to nonblock in my app it says 109(ENOPROTOOPT)

Most calls to recvfrom will fail... because there's no packet waiting. When a packet has been received, the function won't fail and will fill in the from field to let you know who it was from.EDIT2:

Error = ffffffff, -1

recvfrom(sock, RecvBuf, 1514, 0, (struct sockaddr *)&from, &from_len);
You don't seem to know how to use sockets... I suggest you read a few pages and try a few examples on the PC before trying to move to the PSP.EDIT3:

No idea. I just use regular stuff others already have done in other PSP apps. I don't/haven't done any research into PSP networking.EDIT4:

Take this out of the B2 thread. You're cluttering it with unrelated posts.
The bad file error is probably because you're not handling the select right and passing a bad fd to the recvfrom. I probably won't answer anymore posts on this. You need to do more work yourself. We all have stuff we're working on and can't hold your hand on every single step. If I were going to do EVERYTHING, I'd already be doing it.
As to errors, perhaps things have changed slightly in the firmware since I last ran the code... I was on something like 3.90 or something. The behavior may have changed, and no, I'm not going to look into it.

What is the differrence between a router and an ethernet hub? I thought they were the same thing- I have an ethernet hub-can i successfully plug in two computers and have internet access with both? Or do I need a router or what?

A hub and a router are not the same thing - a hub is a simple box that merely connects multiple ethernet sources. A router is a smart device, usually a full computer running linux or some other OS, whose task is to connect to modem, provide NAT, and often a firewall, among other things. A hub can connect multiple computers together as long as the computers do all the work themselves. A router can connect multiple computers to a single modem so that all can get on the net without having to do anything special.daniela wrote:What is the differrence between a router and an ethernet hub?

Add network support...
Add network support...
maybe using udp tunneling like CIPE, OpenVPN or other protocol that suport tunneling and bridging.

Re: Add network support...
It's got UDP tunneling... for AppleTalk networking. You'd need a special server app on a PC to provide internet via UDP tunneling, and I haven't the gumption to put that much work into it.Visigotico wrote:Add network support...
