I've taken a position doing IT/network/server admin with a 501(c)3 non-profit organization, and money is understandably tight. They currently operate a mixed (really mixed) bag network of Mac and Windows computers on an apparently peer-to-peer network, which I'm hoping to upgrade to something representative of this century. My experience in this is limited, but I work cheap.

My most immediate desire is to find a program to scan the network to inventory all the widgets out there, and even better automatically draw a diagram. I've seen at least one out there, but at $299, it'w way outside the budget.

Thanks!

    If you are not limited to Mac OS X for this specific task, then take a look at AutoScan, according to freshmeat:

    "AutoScan is an application designed to explore and manage your network. Entire subnets can be scanned simultaneously without human intervention. It features OS detection, automatic network discovery, a port scanner, a Nessus client, a Samba share browser, and the ability to save the network state."

    Well, as someone who did learn French, even as rusty as I am (reading/speaking French) I can tell you the translation is really rough at best, but at least you can translate the documentation page here:
    http://babel.altavista.com

    eg, NO idea why it can't translate d'exploration , even directly, meaning "of exploration" , so that line should read:
    AutoScan is a tool for exploring, monitoring manageming (a) network(s).

    etc. etc.

    ANYwho, get wireshark, formerly known as Ethereal. And/or Nessus.
    But those won't generate a nework map for you, IIRC.

    Possibly also see what these might do to help:

    ConceptDraw NetDiagrammer
    Visual Route
    Net Monitor

    Hi

    Without spending any money at all launch terminal and:
    ping xxx.xxx.xxx.xxx/24 where xxx.xxx.xxx.xxx is your IP address range.
    Let that run for a bit then issue arp -a in another shell. It does not give you network topology or anything like that but its a useful tool for discovering mac addresses to ip addresses as well as dhcp client ids. IPScanner on the Windows platform is pretty good too. Net Tool Box for OSX/Windows by Charlie Boisseau is pretty good too.

    Hope this helps
