Monitor Froyo hotspot clients?

Hi,
Let's say I want to check, who's connected to my hotspot. I've searched for an application or terminal commands that can show this info, but didn't find anything. Is there such a thing?
Thanks,
William.

Good question, I'm interested as well.
Sent from my Nexus One using XDA App

i never tried to monitor wifi hotspot clients but i think these ways should work.
way 1:
goto terminal, type:
arp -a
this command displays all entries, since the wifi connection actually makes the phone a router, so all connected clients should have corresponding arp entry.
way 2:
goto market and download Network Discovery application, use it to scan the whole network. Also it provides port scanning function too.
(but .. this application usually crashes on my phone after scanning for long time)

Interesting, thanks. I'll test and reply.

Tested, even the basic "busybox arp" with no switches works. The result needs to go through grep or use "specify interface" switch to avoid showing the 3G data IP.
I suppose that access control has to be implemented in the kernel, so I won't mess with it - but now I have a script line to see, who's connected. Thanks
And one day someone could write a widget for it. At least modify the on/off widgets to show the number of connected clients.

Any more news on this? The network discovery app kind of worked, but it had to use wifi which disabled tethering.
I think there has to be a way to see who is connected to your hotspot at one time without disabling anything.
The Palm Pre Plus on Verizon does this automatically. There are a lot of features that phone has that I wish android would impliment...Man it would have been nice if google had bought palm

Is that news?
You want an app/widget for that? There is none. I've turned to the creator of the "hotspot widget" and asked him to implement counter for connected clients (which should good enough for anything I can think of), but I got no answer. I also tried to find any open-source code for such widget to modify and add the functionality, but didn't find any.
The older Eclair CM build had such app for manual control, showing MACs of connected clients.

I dont think the stock froyo tethering implements this but the wired/wireless tether apps included in 2.1 roms has the function, mac address filtering too =D

[Q] University proxy problems

Hi all.
Got my SGS a couple of weeks ago, and (almost) all is great.
I spend most of my time inside the university (I live on campus) and all of the web traffic here passes through a proxy server. Problem is - some of the apps (including the Market) just can't see the connection.
I have (of course) the right Advanced Network Settings (proxy server and port), and this sorts out some of the apps (like the default browser and gmail app), but the market is unreachable, and FB app (for example) can't access the net as well.
Some more data:
I'm running 2.1.
There is no problem to access these sites using a desktop/laptop computer.
I don't use 3G, relying only on WiFi.
Proxy server has no authentication.
Everything works perfectly whenever I leave campus.
Is there anything I can do?
Would this issue be resolved in the (hopefully) forthcoming 2.2 upgrade?
Thanks!

Hey do you have to log in to go online. At my past college and my current uni all android phones where you had to log in via the browser didn't work. However my friend with a Desire with 2.2 can log in, this maybe a wild guess but maybe the updated browser allows for the log in procedures to work, im not sure what its written in, javascript, php, asp no idea but that's my guess> Ive got the same problem if you get it to work let me know and if you know someone with froyo can you ask them to try or maybe its just with newer HTC phones.

Thanks for the reply.
I don't need to log in, there's no authentication, and still there's no access.
It feels like a dodgy implementation of the proxy settings in Android, and I really hope they fix it in 2.2, because it makes my phone really crippled.

Yer I really hope so to on our network their is no pass to access
its completely open but you have to log in via the browser

A quick update.
Just installed a localized (hebrew) version of Froyo (JHJP4 if it interests someone).
I can't comment on anything else at the moment, but the proxy problems are NOT solved. Still can't access the market...

[Q] Can anyone connet thru proxy with latest Dalingrin Kernel?

recently i installed the last eclair kernel from Dalingrin (2/25/11), which among other great things, implements netfilter/iptables
i was able to install both TransProxy and AsProxy, but since i need ntlm authentication to connect to the internet in my office, only AsProxy would be useful for me, but when i hit the start button, it says that the iptables were not found.
has anyone been able to connect to the internet thru a proxy server (in my case an ISA Server), with any of the above mentioned programs or another one?

Have you gotten your iptables to show up yet?
I havent gone the route of ROM yet but I probably will have too. I have asproxy and Orbot (TOR client) installed but without iptables they are useless.

I have the same issue too. Peharps Dal could compile the Kernet to support iptables.

What I had to do for this is set up OpenVPN... Violates my work policy, but oh well. Couldn't figure out how to get it set up any other way.
Technically I did set up an access point on a CentOS box with a transparent proxy, but that doesn't handle syncing which I need at work as I use my tablet during meetings and need to have my schedule up to date etc..

Did you heard about Honeycomb 3.1? Now you can set up proxy and user/psw on the wifi configuration. Nice.. It should be very nice if CM7 got this too...

wht is that how to use it????

well..
it is in the Wireless settings section. i guess you should use L2 IPSec.
briefly: have to set up a VPN server/connection point at home or wherever, and you'll connect to that from anywhere given that there's an open outbound port to the internet where you are currently. than a connection will be built up creating a "tunnel" through which your packets will be transferred to the VPN host where itt could be routed and NAT-ed to the internet unrestricted.
adding IPSec or other methods of encryptions will make your connection secure.
i've never tried it on my phone but since its based on linux it must be the same way as at desktop system.
you should check documents and howtos on the internet and check for apps at Market if the androids builtin is not satisfying!

Use Froyo by Laszlo it supports proxy over wifi

Use your phone's VPN in your computer without root.

I have seen a lot of people wondering about how to use your phone's vpn in pc. If you're one of them, than keep reading.
To do this you do not need root
Works on any computer OS
Works on home wifi or data hotspot
When your PC is connected with your WiFi or hotspot, it's sends all the request directly, regardless of your phone's vpn, wheather it is on or off. When you turn on the phone's VPN, all the traffic from your phone goes through the VPN, and we have to divert your PC's traffic through the same route.
There are a lot of different ways to do this, but we will use proxy method.
Download an app called proxy server (<1MB), you can find it in PlayStore or here on XDA. Or any other app would do, it just needs to have the capability to create a proxy server.
So (for Proxy server app) all you have to do is (first time setup)-
Open the app.
Click on the add button at the top, give it a name.
Remember the port and go back.
On the dialogue, click save.
Click on Info at the top, note the wifi ip, go back.
Click on Start at the top to start the server.
Go to PC's browser (or network proxy, if you want to tunnel everything) settings.
Put the proxy server ip (the wifi ip noted earlier) and the port.
Turn on your phone's VPN
Enjoy :good:
If you're using hotspot, go to pc's network settings or ipconfig (google if you don't know how) to find out the gateway, that will be your proxyserver ip.
Just in case it seems to be a lot of steps, know that, you only have to setup once, after that its pretty much start and stop on both your phone and PC. I have an addon installed in my browser (proxy toggle) so basically it's a single-click step.
I'm no scientist, so I don't know all the billions of methods to do this, but this is just a good old method that's going unnoticed somehow. I'm just trying to help people here by sharing it here. If you already knew it, good for you. If you didn't, congratulations and good luck.
:good:

Please

I think it'd be better if you go watch a video on YouTube, explaining "what is a vpn" . If I try to explain you here, chances are you're going to get confused even more.

Start VPN in phone
Start proxyserver app in phone
Set the proxy IP and port in your PC browser
It's a 3 step process. If you still need help, you should ask more specifically, a generic "more explanation needed" doesn't pin point where should I start.
