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. Regards, 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
    file and only grep out small portion of information which meets my
    criteria.
    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
