Another idea if you are on AIX or
Solaris,
1. On
AIX, use iptrace tool. see iptrace, ipreport man page on
AIX.
2. On
Solaris , use snoop tool. see man page on snoop on
Solaris.
They come with the system and worked very well for me in the
past.
Do not
know the corresponding tools on other operating system
platforms.

Listers,
First, thanks to all that replied to my earlier
post.I'm still a little confused as
to what my options are if I decide to use the nvsniffer
"feature".
Can someone explain to me the capabilities of the
nvsniffer option?I read the man page
and it describes how you can create smartsets that contain the port
information from monitored servers.Does this mean I can configure NetView to
monitor specific TCP ports (ie., 94, 9494, etc...)If so what type of information does this
provide?Is anyone using this
feature?How does this compare to
other sniffer applications?
I'm trying to come up with a plan to monitor the
different TCP ports for the applications (see my earlier post).I would like to avoid introducing third
party applications if at all possible; however I realize there are some
limitations to what NetView can provide.Other than the man page, the NetView
documentation is vague when it comes to this particular
"feature".
Thanks in advance for the
responses.

NVSNIFFER is not a packet sniffer as one would think, the tool just opens and
closes the TCP ports you specify on the hosts or smartset you specify, and if
the host has the port enabled (an application attached or just listening like
the discard port) then nvsniffer knows that port is functional. I
believe the lowest polling resolution is 5 min. You
can only do TCP ports as I suspect that is what you need.
I would
read the man page and doc on nvsniffer to understand the full capabilities if
it.
Here at Princeton we use a tool called ROVER that reads a config file
that has the hosts we want to monitor and also has what ports we want to test
on each. I had hoped to replace ROVERs functions with
NVSNIFFER. NOTE we acquired ROVER code many years ago when it was
free and crude, and have since heavily modified it to suit Princeton.
