Ah, I see...
I think you have been misled by the name of the Net::Pcap lib, the lib
is meant to produce the file you are trying to poke around in.
I would do the follwoing.
* Use Net::SSH or similair to connect to the remote machine.
* On the remote machine use grep or similair to pull out the lines
you are intrested in and store those in an array/file or well
what ever storage you like on your side.
* Process the data on your own machine.
The advantage of this is that you only move the data you are intrested
in over the network and not the whole big file, thus reducing the
network trafic and maning your network admins happy as well. Because
you have the data on your side you can then do with it what you want
without having to rely on any software on the remote machine.
I hope this helps a bit,
Rob

If you can make Net::Pcap connect to a remote server things
will work fine, I am not sure about using Net::Pcap to do this
as I never used it and from the description it seems to be a
packet capture lib not so much a communication one, but as I
said if you can make it reach out and talk to the other side
you should be fine.
I think you will end up using somehting like Net::SSH or
something like that as these are more aimed at communication
then Net::Pcap seems to be.
But in the end as long as the other side is listening on a
port and you can produce the required packets to get
communication going you should be fine, there is no need to
have perl, or any perl libs on the other side all that is
needed is an open port that you can communicate with.
The thing that is listening on that port is what determins
what you can do, read email, open and interact with files or
just browse a web page, perl on your machine cannot change
which process is listening on the other machine.
In short I guess you can if the other machine is listening,
but you might want to use a more suitable lib for it.

Rob

say I have big wireshark file based on remote server.
I want to logon to that server and using Net::Pcap to poke the

Remote server won't have Net::Pcap installed.
I wanted to write this program w/ Expect modules and Net::Pcap
module in my mind.
But since these things are only located in my local server,
will
this work on remote server?

Hi,
local server(w/ Perl installed) -------------------> remote
server(with Pcap file I am interested in poking around)
if I launch a perl script from my local server(using say Net::SSH)
and logs onto remote server, my perl can poke around that file on
remote server
using Net::Pcap.... ? So essentially in order to do this, I need
to use 2 modules(to logon, and then parsing out the pcap file)
I am thinking about writing this but just not sure if it will work
on remote server
but I am interested in grepping out the pcap file so I cannot simply
just do grep
