Network in Qnx 4.25

QNX USERS QNX2 and QNX4
1

Im newbie in QNX and i have trouble with my network. I have a machine with 4.25 and other machines with windows. The problem is when i do a PING over the network it doesnt retrieve me anything.

2

Be more specific!

What do you ping? Why it?
What is the network settings at the windows hosts?

What do you see when you do sin ve at the QNX4 host?

3

Have you set up TCP/IP on the QNX-4.25?

4

We are new to the QNX experience as well and having a fun time trying to debug why the TCP/IP is not communicating with our Linux machines the ping of the Linux systems comes back with

PING 192.168.10.10 (192.168.10.10) 56(84) bytes of data.
From 192.168.10.12: icmp_seq=1 Destination Host Unreachable

Network Background

DNS servers
..**.4
...4
...3
Gateway
...1
Linux Machine
..,12
QNX 4.25 Machine
...10

Not sure if ip is configured correctly but it shows in the table

We did not set up any DNS servers, or the gateway.

Could this be a problem

Is there a step by step tutorial on setting up TCP/IP on the QNX system.

5

Is it possible the MAC address in the netmap file doesn’t match that of the NIC.

What if you ping from QNX to Linux.

6

A ping from the QNX machines gives the same result. Host unreacable.

As for Netmap typing less netmap yields:
one-to-one

Just for the record this is the first time I am trying to setup QNX. Getting te Linux and QNX machines to communicate is not a vital part of the network but it will help for future applications.

We just try to get communication between the machines to see if it would be possible.

As for the MAC address how is it obtained in QNX, we have no reference as it has two onboard network controllers.

7

Please post the output of netinfo -l, ifconfig en1, sin, sin ver.

It should be no problem to create such a setup.

This is odd, it looks like the version of netinfo isn`t uptodate. There is valuable information missing from the output of netinfo -l (number of packet txed and rxed).

Not the cause of the problem, but there is version 5.0 of TCP/IP that is available. Wouldn’t hurt to upgrade.

11

Can TCP/IP 5 be downloaded or should I contact the distributer to purchase it.

12

It should be a free update. Should be able to download if from www.qnx.com

13

Have you set up a route with ‘route’ ?

14

no need for a route, it’s on the same segment.

15

ok , but i just remember some strange effects when we didnt have a default route… Thinking about it though, that was probably because we had two network cards active at the same time.

16

I got TCP/IP 5 installed, not quite certain if it is correct as there is some corrupted file tcptk425to5.changes
and during installation there was something about crypt missing?

Strangely though the second system running on TCP/IP 4.24 can now communicate with the TCP/IP network

I am not sure if our TCP/IP 4.24 installation disk are corrupted or that the TCP/IP requires TCP/IP 4.25 ?

17

Right the QNX box can ping the boxes on the network but does not answer a ping.

While installing TCP/IP5 it was looking for qcrypt otherwise it defaults to beta.

So currently I have beta drivers though using Socket from 4.25

Next problem is I have two QNX machines on the network

ifconfig en1 … determines which pc can answer a ping and both PC’s can send ping across network.

Seems strange that only one PC can answer to a ping.
