Greetings all, I am looking for some tools to work on this data drop problem with from the mobile end. Does anyone have a network connection/bandwidth monitor, telnet, ping, ftp, ssh client and daemons for Windows Mobile ????? I can monitor it from the network end since this is what I do for a living, but need the tools to link up and troubleshoot with. Thanks.
vxutils may do what you want
You may want to check this out: http://www.cam.com/vxutil_pers.html

Thanks
Thanks, grabbed that and checking it out. Now if someone has a telnet and ftp daemon for it we will be complete,,,,maybe this will do it but i bet not.
You could try PocketPutty for telnet:

Edit: Scratch that... I missed the word daemon.

SOLVED - But I'm not sure how, I was redesgning the app so that I could put it up here for other leo owners to test and gave it one last go to take a screenshot of the error to show people what I was looking for and viola it starts working (I never changed the TCP code) sorry anyone who finds this who has the same issue but it just randomly started working!!
Hi fellow devs,
After a massive googling session I have not been able to find an answer to the following issue:
I am writing a TCP client/server app with my PC as the server and the client being my HD2.
I am writing the app in VB.net using the .net compact framework 3.5 and the windows mobile 6 sdk.
I just cannot get the following code on the client side to work over wifi:
Code:
Dim ParsedIPAddress As IPAddress = IPAddress.Parse("192.168.1.10")
Dim client As New TcpClient()
client.Connect(ParsedIPAddress, 7209)
I get the following exception:
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

If I connect the phone via active sync it will work and I can send and recieve data ok so it appears there is no issue with the code itself.
While connected via active sync - if I turn off the server side app I get the following exception:
No connection could be made because the target machine actively refused it
Click to expand...
Click to collapse
However the exception message remains as the original if I do the above but using wifi so it just is not able to establish a link at all (or not even trying) using wifi??
-----------------
I have tried:
1. Ensuring that windows firewall on the server is off and not getting in the way of anything
2. Ensured that my mobile has got an active wifi connection and can see the machine (wifi remote control apps such as GRemotePro work ok)
3. Turned off all other types of data connection (GPRS,3G) to make sure my mobile has only one route out
------------------
Is there anyone out there who has successfully got TCP to work with the .net compact framework and if so how???
Should I be using another class rather than TCPClient maybe the underlying Sockets class?
Any help would be greatly appreciated.
Cheers,
Prime.
P.S. I don't mind if people only have a solution in C# I'm happy to do any translation etc...
Socket class also fails
Ok so I've tried the socket class now as well and that fails in exactly the same way over wifi, ensured that I can ping my device and ping my pc from the device so clearly the underlying hardware is working just not for the TCPClient or Socket... Any ideas anyone?
Have you enabled port forwarding for the relevant port and IP address in your wireless router?
That's the only thing that springs to mind for me.
Thanks for the reply but...
Hey John,
Thanks for trying to help although unfortunately this does not bear any consquence in this particular situation, you only need to do port forwarding if Network Address Translation is going on between you and the end point. In this case the endpoint (IP + Port) is on the internal LAN with no address translation in between. It appears the the internal WIFI adapter is not being accessed correctly from the application i.e. this is an internal issue on the phone not an issue with the network in general as I can run the same code via active sync and it works also I can convert the project to a standard windows pc app and run the same code from a pc and it works. Oh and of course every other damn (this is really wierd) wifi app I've got works so something with the .net cf and wifi maybe??
Cheers,
Tony.
A development...
Ok so I have dug out my old Orbit II just to see if this was device related and low and behold it is ARGGGHHH!!! The app works just fine on the Orbit II over wifi.
Does anyone know of any policies, security or otherwise, that would stop the HD2 (leo) from being able to use wifi from the .net cf?

Generic reasons for communication failures
Hi
This is a pretty generic problem, I'm afraid you can't give an exact idea of where is the problem so I can't give also an exact solution.
Usually a communication problem is due to one of this three
1) The server does not listen or does not receive
2) There is a problem with the network
3) The client does not make the call
Type 1 should be checked trying to connect to the server with a PC or a laptop. You should be able to make the client run in a PC.
Usually when a (web) server has a (web) tcp service stopped, when you try to connect to it it rejects the connection (this is what that of "the target machine refused it" sounds to me). Start then the (web) service on the server. Change (web) for your application.
My advice is that you should have something in the server side where you could run a wireshark sniffer. Then you would see all the traffic coming from the PDA and see if your client is sending packets.
Type 2 are the ones that can be checked with a ping. Maybe there is a firewall somewhere dropping the packets.
Type 3 may be due to several things
a wrong code (I don't know, there is a lot of time since I made programs)
you're trying to connect to a dns name that can't be resolved. Try with IP address.
You have a wrong network configuration. The server should be in the same network but client is not able to get the server's (or the router's) MAC with the ARP protocol. So it doesn't make the call.
I hope it helps.

ssh from your computer over wifi is easy, but doing it over LTE seems to be problematic if not impossible (with the phone acting as the server). It doesn't look like we're given a public ipv4 address and they're just doing an NAT magic to translate it into an ipv4 addy on their end, but it doesnt necessarily link back to you always (if you check your ip over a browser).
With my home connection being SOL as far as having ipv6 thanks to craptactular att "we dont need no ipv6 for our customers," I don't see any possible method to reach the phone.
Blackberries had a static ipv4 (when I had one) but I know that's a dying thing for new phones with ipv4's days numbered.
I know there's other solutions (like vpn), but obviously that's not the same.
i have not had any luck either and that makes sense now cuz i remember having issues with trying to run a server on my phone . damn this is annoying.
I cant get ANY data to work with the exception of once and that was only searching google.com but no other website would work... any ideas anyone?

Nope, not really. Probably could set up a vpn server on my VPS server and and vpn into that to get around the NAT though and do some work in iptables for routing. That was the only thing I could come up with.
Hi,
I know that it was stated that "ssh from your computer over wifi is easy," but this process is not immediately obviously to me. I have succeeded in sshing with the phone, but not into it. Can someone explain how to ssh into the phone (from a computer with wifi that the phone is also connected into)?
Thank you,
Michael

You need an ssh server on your phone. You can either use something like dropbear, which comes by default on most AOSP ROMs and you can figure out how to set it up by reading this or you can use something like sshdroid, which is a GUI app.
I'd be willing to bet that verizion simply blocking ports and not giving you a real ip

Unless you're roaming, you're always behind NAT and an IP within verizon's network. No one is going to give you a real and static ipv4 address nowadays regardless of the mobile network, there just arent enough left. IPv6 however I do not know if it routes out or not, haven't tested yet and the only place that I have an ipv6 address is my remote server so it doesn't do that much good usability wise to me.
Thank you for the really helpful comment! Now for another silly question: imagine the case where you have your phone connected by USB to your computer. Is it still possible to "ssh" into it using one of the methods described above?

if you have the usb cable connected, you could just use adb and type "adb shell"
Otherwise, I don't think so because you aren't registering a network address via usb.
So once you are into your phone with adb, is it possible to run a program like ConnectBot to ssh out from the phone through your computer's adb shell?

Yes, if you mean ssh into your computer's sshd (ssh server).
ssh client (phone) → ssh server (computer)
or you can go the other way as well if you have an ssh server on your phone.
does anyone know how to make a working vpn connection with the touchpad?
i couldnt get one.
i have win 7
tried vnc too,
did anyone get an working vpn connection?
works for me. my proxy server uses pptp so i download pptp plugin from market and all's good.
I think if you have an ASA you can try the built in anayconnect client provided you have a mobile license activated on the Cisco otherwise use IPSEC on your gateway device. I never played with pptp on the touchpad before.
I saw this but what can I do by joining a VPN?
is there someone who can write up an a quick tutorial for the ones that dont know how to do it.
that would be apriated.
i want to control windows 7 remotly with it

Bump... Same question. Out of all the people who have recently bought the touchpad, there has to be someone out there that can give a short explanation on how to use the native VPN capability to connect to a Windows system. I have searched all over the net for the answer and have come across many unanswered forum threads.
Below are instructions I used on Win 7 to create an incoming VPN connection to make it available to be connected to.
pcworld. com/article/210562/how_to_set_up_vpn_in_windows_7. html (take the two spaces out of the link, cant post links yet since Im a NOOB!!)
Step by Step: Building a VPN (Incoming)
Step 1 Click the Start button, and, in the search bar, type Network and Sharing.
Step 2 Click Change Adapter Settings in the left-hand menu.
Step 3 Click File, and then New Incoming Connection.
Step 4 Select the users you'd like to give access to and click Next.
Step 5 Click Through the Internet and select Next.
Step 6 Select the Internet Protocol you'd like to use. (The default TCP/IPv4--the line highlighted in the screenshot below--will work fine.)

On the touchpad when using the Cisco AnyConnect VPN connection type and enter the host name, I get this error "Connection attempt has failed due to configuration issue with server"
When using the VPNC connection type, and enter the host name and password, I am prompted to fill in several fields that I dont know what to enter.
I use my laptop to log into my Win7 desktop all the time easily via the Remote Desktop Connection app. Hopefully there is something similar coming to the touchpad.
I have an openvpn subscription with strongvpn - this works well for the technically deficient peeps like myself to have an added layer of security when using windows machines in a public wifi area (i.e. hotels)
I asked strongvpn about any support for webos, and they were not sure of any workarounds to date. Any new ideas on this? I am using an open vpn (as opposed to their ptpp). They said that on rooted android devices open vpn will work following one of their tutorials.
If you are technically sound only then you will be able to set up a VPN and solve these kind of issues yourself..Average PC users like me will avoid indulging in these configurations as they are too complicated for us
Why not try an already established, reliable VPN service provider for touchpad??
you can definitely Google them and can choose amongst the choices you get..That would be far easier believe me
[Q] VPN support
I was wondering if anyone has tried vpn support on the touchpad? I am looking at using it overseas as a way to watch amazon VOD while I travel.
Edit: Found out I needed to download a free app from app catalog for PTP support. Works now when I connect to my school network. Also I found out that playon services work too on touchpad so I might try that for netflix.
Hi everyone,
I am trying to get my head around on what can be done to bypass the tethering filter on 3UK.
Below are different scenarios I have come up with and would like any volunteers who could try out any of the following for me. Of course I will be doing these myself as and when time permits but its always helpful to have others view on it too.
Please and I say please, do not turn this thread into Right and Wrongs of tethering or Terms and conditions of 3 mobile contracts. Please keep your views to yourself regarding if its lawful or unlawful or ethical or unethical or whatever you seem to come up with. I would like this to be a productive thread, instead of random comments on tethering.
Option 1: Use SSH Tunnel * Should I use SSH tunnel on my phone and use my PC to connect to it to use internet. Is there a reverse option?
Option 2: Use OpenVPN Install OpenVPN on your pc, and connect your phone to your pc using default VPN function on your phone in my case GT-I9100 comes with VPN function. You could also try to reverse this method and install OpenVPN on your phone and use your PC to connect to it. *
Option 3: Use the above two together in combination As the heading says, use SSH tunnel to connect to your OpenVPN.
Option 4: Use a proxy on your pc and connect to your phone or reverse, install proxy app on your phone and point your pc web browser to that proxy address. You could use the SSH tunnel here to connect too.
So, tools at hand are vpn with any encryption available, ssh tunnel, proxy server.
Tools to ignore - TOR (onion), garlic based TOR like, changing User Agent on web browsers or paid VPN.
3 UK has two APN settings, three.co.uk for mobiles (NATd ip address) and 3internet (dongle users) has external IP address and I believe it’s an Open NAT or no NAT.
Please feel free to mix and match any options and also share your views on what is technically possible.
I hope to see something useful and learn a bit more. Even if we fail to achieve the desired results, it will still be enlightening to find the facts on how 3 detects tethering.
I
Code encode decode
Found on giff gaff forum useful info
Well, they have a few ways..TTL: In my opinion, the most likely telltale signal of tethering. For example, *iOS packets originate with a TTL of 64, so if they see anything else they know something is up. This is very easy to check, as the TTL is checked by each router as the packet is handled. (the address on the envelope - doesn't require opening the letter, to use an analog analogy)APN: Another possible sign of tethering is data being routed over the access point set up for the built-in tethering feature. But giffgaff does NOT have a separate APN for Tethering. Again, this is easy to check without deep packet inspection.User-agent: This is where carriers would need to get heavy-duty equipment and a willingness to be invasive to detect tethering. Your browser sends information about itself to remote web servers, and this information could be checked. I do not think giffgaff is doing this (to detect tethering at least,) as it is not proof of tethering since anyone can easily use another browser on your phone that reports a different User Agent.Web Sites Visited: Again, highly invasive, though it doesn't require DPI. If you're using the DNS servers of the carrier, they could look for requests for certain domain names like windowsupdate.com etc. This wouldn't be proof either, though.I would bet that they are using TTL. So tunneling the TCP/IP packets that way probably resets the TTL to the default of the WAN interface on the phone.
Code encode decode
Why do you have to make 2 threads for the same subject?
Well I wasn't sure at the time of writing first one if I had to go down the route of testing which the second one is for. So, the first one is literally to know if its happening to new contracts only and second is for testing different scenarios and finding how.
Hope this helps and if not then jog on.

Less of the attitude please and more of the reading of forum rules. Stick to one thread for the same thing.
Thread closed, use the other one (it was created first).
So I'm trying to do some research in the server requests and responses of some apps I work with, and for various reasons need a hotspot because of incompatibility with a corporate proxy.
Are there any apps that can decode/record web traffic as it's passed to AP clients through Wi-Fi tether?
I certainly recognize the possibility for espionage / inherent security concerns, but they have similar apps for desktops like "Charles proxy" or "fiddler" to do research in packet analysis.
I googled a little, but most examples were from the 2.2-2.3 days, and didn't seem updated at all.
Thanks!

Yeah, that's the wrong type of proxy. I need the *phone* to act as the proxy, or at least decrypt ssl traffic between the phone and tethered device; this one is more of a "hide my traffic" proxy between the phone and the internet.
But this is exactly what SandroProxy do. It acts as local proxy accepting requests.
For SSL you need also to use Menu->Export CA to store.
It can also connect to your corporate proxy (basic/digest/ntlm) so you do not need to use thether mode.
