TCPIP trace 4.25E

I have a 4.25E load with connections to our UNIX servers,
I have been notified that our UNIX people have loaded new network tools and found that QNX is sending out a TCPIP packet to every nine seconds (no one knows for how long its been going on).
I tried to find the packet or scripts that would do a send with as a destination and no luck.
Does anyone know of a command to see what is being sent out of the socket?

You could do sin fd. That will show all TCP/IP connection. Maybe that will point to the program that is doing that.

I don’t know of any command to see what is send out of socket, usually that is what sniffer are for.

Kill every software one by one , until these packet aren’t sent. Then you’ll know which process is doing that.
