If you are using visio, I know visio 2002 has a network auto discovery feature, where it will go out and find nodes on the network. I am not sure witch versions (i.e. standard, professional ...) that this is with. Good luck.

We're running an ISP access network (about 20 nodes) and I don't want to update visio drawings manually while all topology info is in a database. Besides that, I would like to generate a similar drawing for the customer's access link and their router on a web portal. I could probably do the latter with GD.pm, but I feel a bit like reinventing the wheel and rather have a more generic solution. The database contains a table like this: IPaddr, hostname, interface, network I understand I will need to supply some hints for the layout generation, like a rank or coordinates for each node. I looked at caida.org, but these are all for large backbone networks. I've also been playing with dot and neato by generating the input file from our database, but I can't get it to produce a decent layout, the "ranking" feature of dot seems too limited. W.r.t. neato, being an access network, there is a clear hierarchy in the nodes, so a spring-model graph layout is not suited either. =20 Any ideas ? thanks and hoping it was not too far off-topic, Wim.
