QNET over IP on QNX 6.4.0 - automatic population of remote nodes in /net folder   
hi,
I am porting my project from QNX 6.3.0 to QNX 6.4.0.
I have issues with QNET ovet iP.
When i mount QNET over ip with dns option untill and unless i do a TDP operation on remote node,will not get it in /net 
list.
I need a automatic population of remode nodes list in /net folder with IP option.
Is there any way to do so?
Do i need to create a new resolver ?
Where can i get the code examples for writing a resolver?

I can't think of a good way to do this.

That's one possibility

Qnet resolvers can be complex because of the
multi-threading.  I might suggest altering the
existing dns resolver to give it the behaviour
you want - remember, all the source to qnet is
publicly available to anyone!

I'm told svn repository viewer links work outside 
the company, but I am doubtful:

http://svn.ott.qnx.com/view/core_networking/trunk/sys/lsm/qnet/nr/nr_dns
.c?revision=904&view=markup

P.S.  69603 created to track this request - add
auto-populate to qnet dns resolver.

Don't hold your breath on this one, though.

hi,
Does any one let me the status of P.S.  69603 .
In future is there any chance that  i get auto pop up of /net with QNET over IP.?? in the later versions of QNX 6.4.X???

Any idea..??
Its the major stop issue for me  for migration to QNX 6.4.0

It wasn't removed - it's simply a difference between
the resolvers used with ethernet bind, and ip bind.

I had no idea that anyone considered the "hints"
in /net an important feature!  I personally think
they're nice to see, but whether or not they are
there should not really affect the time it takes
to resolve a new host.

Re: RE: RE: QNET over IP on QNX 6.4.0 - automatic population of remote nodes in /net folder   
Its definitely an important feature for our project.
In our project the total application depends on the "/net" folder.
If /net is populated automatically then there will not be an extra stuff to the TDP oeration and make an entry in /net.
i mean I need not maintain a lists in /etc/hosts.
If a hostname is changed again its a big headache to modify the /etc/hosts file...on all the nodes.
