Which router am i connected to software

[southwell]

We have about 30 AP's in our workplace and are having an issue with a couple. Does anyone know of any software that will tell me which one the laptop is connected to? We think two of them keep picking up and dropping the laptops in the area and thus causing them to lose network connection.

Thanks

Oops, i mean access point, not router.

I take it they all have the same SSID?

[southwell]

Yes.

[DocDutch]

how have you set the AP's up? chain linked them all in a bridge setup or star configuration?

also do you know which AP is causing the issue or are you trying to find this out?

[southwell]

They are a star configuration. We 'think' we know which two are doing it. I just want to try to replicate the problem others say they are having and i can't. This may be due to me having a decent Dell laptop and the others having Novatech own brand laptops though. It would be nice to have a bit of software that will show which AP the laptops are switching inbetween.

Cheers

dont know if there is any software that will tell you which lappy is connected to what AP.

if you can be bothered to learn some scripting then rebol should be able to do that for you, and make a good GUI if you put the effort in.

make a script that you run on any machine you like, make it into a client/server type script and collect all the data you like.

Determining IP Addresses

"I was wondering if there is a way to use REBOL to determine the ip addresses currently connected to my local machine if its acting as a proxy.

I believe the answer is no but was interested how I might determine that or another language that could do that and interface with REBOL by means of exchange that data via a tcp port."

Do you mean the IP address of the remote end of a connected TCP port ? You can find that in port/remote-ip.

The IP address of the local end of the connection is in port/local-ip. Additionally there are port/remote-port and port/local-port for the port numbers.

Or are you trying to find the IP addresses assigned to the interfaces of your machine ? With current experimentals try "get-modes udp:// 'interfaces".

This returns a block of objects that contain network configuration paramenters, including IP addresses. Works with most operating systems (not with BeOS and Elate though).

Building a server engine

If you want to start using REBOL for server applications, you may consider building a server engine for all network communications. In this article I'll describe the HIgh Performance Engine of Rugby, hipe.

Hipe provides you with a TCP and UDP based server framework, and a simple form of threading.

What kind of features do we expect from a server framework?

• TCP and UDP capable, as these are the dominant protocols of the Internet.
• Easy addition of protocol handlers built on top of hipe.
• Good performance.
• Some simple form of threading. This is useful to start little tasks while we are in the network event loop.

So let's start our script with

Scripting shouldn't be a problem, ill have a look into that, thanks very much.

if you prefer to use a browser as your front end rather than the cli/shell or make your own GUI in 'rebol/view' then you might try using the browser plugin.

Wouldn't netstumber do this?

well yeah i supose so as a one off,and you could probably cobble several of the wireless apps together to create a kind of long term monitoring/reporting shell script thing.

but he said he's got about 30 AP's and so i thought he might like to do a better long term job, as well as see if he likes rebol to create something far better and professional or just for :fun: and it would probably work out far quicker for most people writing rebol/view scripts.

everyone thats good at scripting should try rebol and then start releasing loads of scripts for interesting TCP:ip projects .

Now I'm not actually sure that it's possible to find what access port you are connected to via any TCP method. APs are layer-2 devices not layer-3 (unless they are doing something odd) so for example they won't show up in a tracert.

I was once in a similar position with a company which had 22 Netgear APs dotted throughout the office and what I ended up doing was to look at the configuration pages for each AP and see which machines (listed by MAC address) were associated with each one. It's not as arduous as it sounds since you can start with the one physically nearest the problematic computer and work outwards from there until you find the MAC address of the PC listed.

[southwell]

I ended up using a program called netstumbler, unfortunately it threw up more questions than answers. The laptop skips through the two closest AP's and then locks onto one with half the signal strength. At least i now have some figures and graphs i can go back to the networking guys with.

thanks all.
