onder Posted January 30, 2008 Posted January 30, 2008 Hi, Does anybody knows a free software that scan our network to draw a network map by itself. Thanks,
Uraken Posted January 30, 2008 Posted January 30, 2008 solar winds do lan surveyor, its not free but there is a 30 day trial which could you give you a start point.
MarkB Posted January 30, 2008 Posted January 30, 2008 I would recommend The Dude, it's free. It's not perfect and I did have to manually tweek the map afterwards. I've uploaded the map I produced with it, it is a bit big 1.57MB and can be found here

GrumbleDook Posted January 30, 2008 Posted January 30, 2008 Try and do it when there are no staff around using wireless. The Dude gets confused when it is scanning and finds the same laptop on a few different APs due to people moving around.
rush_tech Posted January 30, 2008 Posted January 30, 2008 What make and model of access point? mostly 3com 8750's with some 3com 7760 @grumbledook we did it during the summer holidays so there was no one using wireless network
strawberry Posted January 30, 2008 Posted January 30, 2008 sorry to hijack a thread. Everytime i use one of these programs it gives me a flat map and doesn't show me which devices are plugged into which switches. Could this be because my switches are on a different subnet to everything else?
Geoff Posted January 30, 2008 Posted January 30, 2008 Ah, you want some software that actually works out the wiring links between the switches? Are these switches managed and have SNMP?
ZeroHour Posted January 30, 2008 Posted January 30, 2008 3com do a free tool called Network Supervisor. There is a commercial version but hunt and you will find the free one. It does the job for us here and it does work with all switches as well I believe.

Hello Geoff, was this for me?. If so I'm looking for something to identify whats plugged into each switch for me as i have a few random ports aroudn the school. The switches are all hp 2626.
sidewinder Posted January 30, 2008 Posted January 30, 2008 Im the same, I run the Dude and get nothing like what MarkB got, I just get a flat map, with every single device: computers, switches and printers all connected to one cloud with the network id in it
Geoff Posted January 30, 2008 Posted January 30, 2008 Yes, that was aimed at you strawberry. I suggest you have a look at the 3com software Zerohour suggested. Failing that, you'll have to pay $$$ as I have not seen any free software that will generate a proper topology map.
sahmeepee Posted January 30, 2008 Posted January 30, 2008 We use 3com NS here too (the free one). As well as the layout it will let you launch the web management for each switch, set up QoS (IIRC) and also show you health alerts if you turn the monitoring on (e.g. slow fans, saturated links). Very good for a freebie.
Geoff Posted January 30, 2008 Posted January 30, 2008 If anyone finds a working link to the free 3com Network Supervisor, can they post it. I can only find trial versions :/
SpuffMonkey Posted January 31, 2008 Posted January 31, 2008 If anyone finds a working link to the free 3com Network Supervisor, can they post it. I can only find trial versions :/ Just got it from here http://www.3com.com/products/en_US/result.jsp?selected=4&sort=effdt&sku=3C15100E&order=desc You have to register it afterwards - but it says its good to run
