check inbound traffic on ports - UNIX for Advanced & Expert Users

sunoracle · #1 (**permalink**) 03-18-2002

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)

Code:

/dev/net1    00:a0:c9:e1:64:14     00:a0:c9:e1:64:14

/dev/net2    00:04:ac:4c:cc:4c     00:04:ac:4c:cc:4c
      Unicast  Multicast Broadcast  Error    Octets   Queue Length

Hope that helps some
