TCP/IP stack

Postby Angshuman Sarkar » Fri Aug 27, 2004 8:39 am

hello all,
I am trying to make a TCP/IP stack over io-net. I hv
just started to work on QNX, so my knowledge is
limited. I found some documentation, in the DDK
Network section there is a sample code for writing
driver of a hardware, but there is none (i guess) for
writing the TCP/IP stack. I guess i will have to use
_REG_PRODUCER_DOWN when registering, but no such
tutorial is available. Can anyone please let me know
ehere can i find such documentation.
Please also let me know, if i am walking in completely
the wrong track!!!
Help.
Ansuman

i am a student of comp sc in india. this is my final
yr project. so i would hv to do it myself :| . thanx
for the help.

When creating the TCP/IP stack i have used
_REG_PRODIRER_DOWN. Now the question is when
advertising I have to send a packet upwards using,
alloc_up_npkt . but the STACK is a down producer for
io-net. So is advertising necessary in this case, at
all? if yes, then is the method same as that of a
network card ( as given in the documentation ).

Also... is npm-ttcpip.so open source or freely
downloadable? can i view the source? is there any
elaborate documentation or any help if i want to write
a driver as a TCP/IP stack for QNX, not a hardware
driver.

Please Help...

Starting from the document above. (The 6.2.1
DDK-Network Driver Doc). It
is way more detail then the 6.3 one. (the 6.3 DDK is
more concentrate on
driver).

A stack is a down producer (it could also an upper
producer but depends
on what he want to do). A down producer is just
_REG_PRODUCER_DOWN, and
everything else would be almost the same as a
driver.

We have a group of QNX consultants at
www.openqnx.com that can do the
work for you at a reasonable rate. Let me know if
you are interested.
