Hi everybody

I'm looking for a software with this characteristics:

1) runs on linux, no matter the distribution. 32 bit may be ok
2) can scan a network and build network topology, in the form of an oriented graph
3) the topology is at device port level, e.g. switch06ort2(macaddress) is connected to switch08ort4(macaddress) ; switch11ort23(macaddress) is connected to access point (macaddress) ; and so on
4) doesn't need a db ( NeDi ( nedi.ch ) does )
5) no graphical interface, but this is not really a requirement, I can manage this
6) can manage virtual ports, like trunks, lacp, vlan. This is also not a real requirement
6) can output result in text form ( csv, perl, json, whatever, but text )

I looked at http://www.slac.stanford.edu/xorg/nmtf/nmtf-tools.html, and tried some of the software described, with poor luck.
The best sw suiting my needs is https://www.lantopolog.com/ but is for windows and, alas, 32-bit, thus preventing me even from trying wine ...
Monitoring engines like openms, nagios, opmanager ecc are a bit out of scope, I have to install the tool in a production system, and have limited freedom of action

The only pertaining thread is about 3 years old.http://www.linuxquestions.org/questi...s-tool-736592/

Suggestions?

Thank in advanced, and sorry for my bad english

You could look at Cheops-ng.

Thanks AwesomeMachine, I actually did, even if it is unmantained since more than 10 years and it won't even compile on Centos 6. It does the same, or even less, than zenmap.
Zenmap itself is not usefull to my purposes because it doesn't tell in which physical port of a switch the devices are connected to. I need a level 2 and 3 topology description.
NeDi would be perfect, but it needs a mysql or postgres db and I can't do such a modification in a customer production system....

Just my 2 cents, if you have access to the configuration of the switch (I suppose it's a manage switch) then you can just export the data with the MAC plus the port it's connected to. If it's not a manage switch then I think it's quite hard to tell which network port the computer is connected to.

Then you can just go to your DHCP server, export the IP Address leasing compare it to your switch data.

Last thing, create a script to dump the MAC Address, IP Address, Computer Name and the User Name using the specific computer.

After that, close and open the DVD/CD-ROM for those users you want to scare. LOL.

Yes, I know you're looking for a software but you can do the above steps without worrying whether the software has malicious code or not. Of course, the investment is your time and effort.

There are about 60 switches, 8 different spanning tree rings, hundreds of access point, tens and dozenz of physical and virtual servers, firewalls and so on, and poor documentations about which device/port is connected to device/port.
Follow the cables by hand would be crazy, very limited installation of software is possbile, and no foreign hardware can be deplyed.... I have started to write my own tool.

@AwesomeMachine, why do you think Ubuntu is spyware? I have been suspicious of this OS for a long time too, but where is the proof? Thanks, - A.

Wow, you inherited a mess.
Just pull out the cable, if anyone shouts hey i'm offline. Then you know that ports belong to that guy. LOL.

But I think you can document it, of course it won't happen overnight.

Good luck man!
