I am looking for a software that can create a network topology diagram that runs on OSX. Please give me your suggestions. Thank you!

Infoblox has a VM tool for network discovery and reporting (don't think it will do diagrams though): – MaQleod Jun 12 '14 at 23:07

I don't know what do you want exactly, but you can try the lansurveyor.

Discovers and draws topological maps for TCP/IP and AppleTalk networks. Features network node Up/down testing (polling) for both TCP/IP and AppleTalk nodes with alerts, including paging and email.

  • Automatically discovers and diagrams network topology
  • Supports generation of network maps in Microsoft Office® Visio®
  • Automatically detects new devices and changes to network topology
  • Simplifies inventory management for hardware and software assets
  • Addresses reporting needs for PCI compliance and other regulatory requirements

You might want to try "Zenmap" (an nmap GUI implementation), the download link is: The OSX link is somewhere at the bottom of the page.

It’s maybe not the perfect »topology mapper« (though it has a nice clickable graphic mode) but offers a lot of insight due to using nmap »under the hood«.

Have fun!

Thanks for your reply. It worked but not sure how to use the Topology feature. Seems like my localhost is in the center of everything instead of my router. Advice? – rabbid Feb 25 '13 at 23:29
Is it at all possible that your network setup is »bad«? (I.e., your machine is not in the same network, has a bad subnet mask, or the like?) Can you »ping« any of the other devices? If your network setup is correct, it might still be some settings on the other devices to be scanned: Restrictive firewalling, or ICMP echo requests are disabled. Still odd. I’ve seldom run across a network that nmap (or Zenmap, in this case) couldn’t somehow »see«. Anyone? – Moonbase Feb 25 '13 at 23:37
Re: Topology: Unfortunately, I’m on my laptop now and can’t boot into Linux rightaway, but … I think I remember that clicking on any one device will bring it into the center. and re-arrange the topology map. Also, play with the settings (zoom, etc.) on the right. – Moonbase Feb 25 '13 at 23:42
Maybe this helps for moving around in the topology map … Good luck! – Moonbase Feb 25 '13 at 23:45
Yes I can move the router to the middle. My question is about the lines that shows connection between devices, and all devices are pictured as connected directly to my local host and not through the router as I would expect. I thought the trace route function is supposed to figure that out? I probably just don't understand fully how to use this yet. I did read the manual but haven't found anything about this. Thanks – rabbid Feb 26 '13 at 6:27
