check inbound traffic on ports

UNIX for Advanced & Expert Users
1

Hello,

I'm new to the forum and would like to know how to check
inbound traffic on various port numbers.

I would also like to know how to open and close various ports
on a unix box running solaris 8.

Thanks in advance.

Not exactly what you're after, but you can check stats like so...

date +'%d-%h-%Y %X %Z' >> /some_stats/net/netstats
ndstat | grep -e dev -e Octets -e In: -e Out: >> /some_stats/net/netstats

Will provide stats like the following: (two network cards attached to a SCO box - in this case)
