TCPIP QNX4.25

I install QNX4.25 on a desktop computer with a intel 82557 100mb ethernet
card

Net service is running
Net.ether82557 is running

I can ping node1 (the adresse of the card), but not another machine.
My hardware is correct because if I boot with another OS system, I can ping
other machines

I install another node (node2) complete different hardware exept the
ethernet card. Same problem.

I know both card are good but, with QNX ???

HOW CAN I DEBUG MY TCPIP CONNECTION ?
Is there a process missing ?

There are several issues.

First, make sure that you have the latest Net.ether82557 driver. The
earlier drivers had problems with 100 MBps. I am no longer using this
driver so I can’t give you an executale date. Hopfully someone else can.
Are you able to do QNX networking at 100 MBps? If so, then this is not the
issue.

The next thing to check is your TCP/IP configuration. I would type a:
netstat -ni ; netstat -nr

If fact I type this so often that I have an alias called ‘ns’ that does
exactly this. The -ni will show the known interfaces (the -i part, the -n
part says use numbers, not names).

Make sure that TCP/IP is aware of your ethernet connection, and knows that
it is up. Make sure that it knows the correct IP address for your ethernet.
(BTW, there was once a bug where it was necessary to do an “ifconfig en? up”
even if netstat claimed that it was already up. I.E. you had to give it the
‘up’ part. An ifconfig that merely gave it the ip address was not enough.)

Make sure that there is a defined route (either a default route, a network
route or a specific route) (look at the output from ‘netstat -nr’) to the IP
address that you are trying to ping.

Make sure that the other host also has a route back to this host.

Hi Vincent,

You must run Socket or Socklet.
Once this process is running you can configure your interfaces using ‘ifconfig’ command.
Look up Socket, Socklet and ifconfig in the helpviewer for more information.

Joe

The shell script ‘/etc/netstart’ is a good place to start with …
