Network topology inference

Hi,

Please, I would like to know if is it possible to infer the topology
of a network using linux tools.

For instance: I have a network, and I want to generate a graph showing
the nodes in the net, maybe graphically grouped in subnets, and linked
to their servers.

Thanks a lot.

Regards,
Daniel Sadoc

Nope, scotty can discover a network using SNMP auto-magically.

AFAIR there is a IP-Discover tool, somehow point and click, after hosts
are discovered you need to put in some work to make a nice picture, make
sure you save it.

Dunno about tutorials, perhaps a google search shows some.

BTW
Please stop top-posting.

Sorry for this off-topic question but, what is top-posting anyway?

Sigh. The old discussion... Some people feel that a response should be
below the quoted text. In certain cases, there are good reasons for it.

As a rule of thumb, top-posting is superior when responding to a short
note (such as yours), while bottom posting tends to have advantages when
responding to several individual points in a longer post.

Unfortunately, some people are very dogmatic about bottom-posting (I have
yet to see somebody dogmatic in favor of top-posting) and will flame you,
most of the time in computer-related newsgroups.

Far more important is to keep the posting style - don't bottom post if the
thread is already using top-posting, and don't top-post if the thread is
already using bottom-posting. By that criterion, Daniel indeed should have
bottom-posted.

But that's also why I deliberately top-posted my response to you and
believe that it actually is the better method in this particular case.

Hi,

Thanks again, Michael. I've just tried to use the IP-Discover tool of
scotty, and in fact it gives me the number of hosts found in my
network. But I wasn't able to find out a way to get the IPs of all
the machines.

I have to put all the information I get inside the nodes, one by one?
Or just to move the nodes on the screen?

For instance, if I get 100 machines, I will have to insert 100 IPs,
one in each node? Or scotty does it automatically?

I'm still looking for scotty/tkinetd tutorials.
