Tracing Sockets based comms on single server

Steve Roberts — Mon, 13 Nov 2000 12:05:06 GMT

I have looked at most of the recommended utilities, but cannot find something which doesnt rely on actual traffic crossing a machine boundary. Our app uses unix domain sockets to implement inter-process comms on the one server (HPUX 11). Is there a way to fool, say, TCPDUMP, into seeing this traffic ?

Thanks

In order to trace all packets sent by node and addressed to node :

1) start trace putting data into 1MB trace file ( /tmp/raw.TRC0, raw.TRC1).
/etc/nettl -tn -pduin -pduout -e all -f /tmp/raw

2) stop trace -> /etc/nettl -tf -e all
3) Format traces into a file like this :

/etc/netfmt -N -n -l -f /tmp/raw.TRC0 > /tmp/file0

/etc/netfmt -N -n -l -f /tmp/raw.TRC1 > /tmp/file1

-n option -> print IP addresses, not hostnames

I hope this helps
