"netstat -i <interval>" would be better if you are asking about packets like stated in your initial question.

yes "netstat - i" gives mi a packets, but I would rather have sent/received bytes..

Code:
kstat -n interface | grep s64

should print both the packet and byte statistics for the specified interface.

Hi jlliagre, thank you,but the command doesn`t do anything. When I use the "netstat" command, there is a row like "tcpOutDataBytes" which I assume are bytes sent out, but dont know which row is "data sent in"...

What interface do you use ?
What Solaris 10 release (cat /etc/release) ?
What says
Code:
kstat -n interface

(with interface replaced by your interface name)

The closer would be tcpInAckBytes but TCP statistics include local (internal) communication so is probably not what you are looking for.

As interface I use TCP
I use Solrais 2009.06 snv_111b X86
when I use "jack@opensolaris:/# kstat -n tcp | grep s64" I can hear HDD runnig for a while and then it prints again "jack@opensolaris:/#"

So can you point me to where (what command) I should look?

Thank you very much

"tcp" is hardly a network interface. It should be e1000g0, iwh0 or something similar.
What says
Code:
ifconfig -a

?
