Re: TCP/IP stack

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...

Using XFree86 on node without TCP/IP

Hello,

I am trying to install XFree86 for QNX 4.XX on a node other than one that
does not have TCP/IP installed. We normally use the facilities on node 1
that does have TCP/IP by using the 'on -f'. We do not do development work on
that node so I would like to install it on my node for some graphics
experiments using Mesa.

Is there a configuration file where TCP startup can be disabled? Or do I
need to modify some code in the XFree86 project to disable socket use and
startup? Not that I would know where to start.

Thanks,
		Keith

How can I use floppy disk drive."

Hello Everybody,
 
  I have installed QNX 4.5 in my new 'HP Presario 1115L'  machine using QNX installation CD. I am facing the following problems.
 
1. I couldn't make a QNX boot floppy during the installation. Even if I had inserted a new floppy disk in the drive, it was asking me to insert a disk in the floppy drive (It was not detecting the floppy disk - so I aborted that).
 
2. After the installation I am not able to boot from the hard disk. (I am using LILO as the boot loader - The other 2 OSs are booting well).
  So I maid a QNX boot floppy from my friend's system and using that  I am able to boot QNX in my system (Though the floppy drive was not detecting during the installation!!).
 
3. After booting QNX using the floppy, I am not able to mount any floppy disk using the mount comand. While trying that, getting the following error message:
mount: mount() of /dev/fd0 failed: Input/Output error.(I maid sure that the Fsys.floppy is running.)
(Even the fdformat & dinit commands are not working.)
 
So what will be the problems? It will be a great help if anyone can give me a solution for these problems.
(1. Not booting from the Harddisk.
 2. Not able to use the Floppy drive)
 
Thanking you all in advance
Jens.
(I am a beginner in QNX, but very curious on it)

Getting an error display, vp_freepkt: Bad file descriptor.

Hello all,
 
  We have developed a bandwidth regulating software in QNX4.5(In application space).  We are getting the network packets into the application space using the Virtual Packet Interface(VPI) and regulating them and send it back using the same VPI.
 
  It's working fine with moderate network traffic. But in the case of heavy traffic, it's working but displays the following error message continuously.
 
  vp_freepkt: Bad file descriptor.
 
If anybody have any idea about this, please let me know.
 
Thanks in advance
Jith.

Re: Getting an error display, vp_freepkt: Bad file descriptor.

Maybe you ran out of file descriptors, and possibly other resources.
Try to increase that (make a new boot image).

Re: How can I use floppy disk drive."

1) is the hard disk too big? and QNX partition beyond cylinder 1024?
What's on the screen when you try to boot the HD?

2) QNX 4 has some issues with the new Pentium machine. Most of the
community QNX users are using QNX 6 because it is free. QNX 4 is very
expensive and there are all commercial users. You may want to contact
QNX for a new version of Fsys.floppy that works with Pentium machine.
