Hello Leif and Others,


Fully agree with what you stated here.

On the feedback part. 

One needs to be very inviting and patient I think.

It is really interesting I tried to do the networking first quite a while
ago and then I did not get anywhere, Thought "lets wait, there will be questions
and answers and you will understand howto it by then".
The feed back part!

Then thought that the system wanted to work perhaps with the 239,555.0.0 I think it
is.  the 239 address hard programmed into Linrad )
So I thought,  if I set manually the IP of the network card to that address
it might perhaps work!

Then I found for whatever reason I can not set the first block to 239, 
( 239 invalid should be < 223 )

I guess I stppped at that time

So that was some of the process here.

I have been programmed today to ask when it comes to communicating
with instruments, programs and the like, the IP addresses?

In short, my approach to computer problems is not
necessary menu clicking. I don't dare to go into unknown
area's when it comes to computers. ( dare is perhaps too strong )
A generational thing I believe!

"Don't turn knobs , move handles if you do not know what will happen"

I know from work experience many others and particular younger people
act completely different.

I suggest to add to the basic Linrad package 2 files, empty or with
neutral text.

par_netsend_ip
par_netrec_ip

The user is suggested to modify these files during network setup.

I tried to find and was asking for something along those lines earlier.

Besides that to write ( we can do that ) a general piece about network
issues in relation to LINRAD and MAP65 and perhaps about connecting
computers to programs, instruments, black boxes.

Leif I believe you have a tendency to inform after one pushes. This means
that if one does not push, one never learns or gets informed.

You also put the help files after the pushing, again what can I say, 
remember it! 


This is nothing critical and perhaps it is not even quite true but
I have that impression. Also this is only in relation to the linrad
program

I like to know the way before I push. It all comes down how one approaches
to solve a problem or answer a question.

BTW I have a whole bunch of questions about this part the "R". "T" , "W" as well
as "0" ) zero . But we can go over this later.

I like to suggest we start a new section with questions and answers 
and that some one, you , I or who ever want to do this compiles a 
file of the questions , answers and solutions, from the reflector
content, with all the reflector house keeping removed. As this
file grows it will be posted on the web,

For me at least, it is very difficult and time consuming to extract the 
relevant info and details from the Google type of protocol. 

For this job I don't want to push myself  but I can do it and post it.
That is if no volunteers come forward. 

Pse your and others comments before we go.
