Can anyone enlighten me on this one? Seems one of the most useless things that could be on the phone (along with the ram/memory cleaners and antiviruses, which basically is the Device Maintenance tool).
Thanks!
it is Samsung's vpn solution. you get 250 mbytes free per month. It creates a secure tunnel to their vpn server over wi-fi . It is mainly used when connecting to public wifi , which is seen as a hostile environment.

Hello,
Has anyone heard of any Ptunnel implementations for Windows Mobile (CE)? I would love to get this running on my Rhodium.
Ptunnel is an application that allows you to reliably tunnel TCP connections to a remote host using ICMP echo request and reply packets, commonly known as ping requests and replies.
Setting: You're on the go, and stumble across an open wireless network. The network gives you an IP address, but won't let you send TCP or UDP packets out to the rest of the internet, for instance to check your mail. What to do? By chance, you discover that the network will allow you to ping any computer on the rest of the internet. With ptunnel, you can utilize this feature to check your mail, or do other things that require TCP.
The only reference to Ptunnel on Windows Mobile is here:
http://unsyncopated.com/wiki/ICMP Echo Request Tunnel for Windows Mobile 5
Has anyone tried anything like this?
Has anyone heard of this concept?
I use pocketputty and ssh tunnels. If you have access to an ssh shell, you can easily set up any local port to tunnel to different hosts.
This is a good writeup on what ssh tunneling is, and how it works. It mainly is written for full Windows Putty or linux ssh, but pocketputty setup is alot the same.

As a network admin, I hate you I hate you I hate you. Wasting my bandwidth inefficiently sending TCP over ICMP (at an overhead that approaches 100%) and screwing over the paying customers (because I prioritize ICMP, so your packets lag theirs) is not cool.
Moreover, it is in fact illegal in the US and while I'm not such a curmudgeonly bastard to press charges, many other admins will. Consider yourself warned.

Yes, but SSH runs over regular TCP, which would require (GASPS!) paying for wifi!
Yes, specifically I am looking for a tool to run traffic over ICMP.
And I understand the questionable nature of this proposition, I am more interested in the technical nature of this implementation, just to see if it can be done.
I guess I could tether my phone to a PC and try running Ptunnel on a Linux box?

Can you cite a source on this? I know of no criminal laws (which would have to be federal in this case) specifying anything to do with TCP/IP packet types. For now I'm going to have to call BS on that.

There are probably laws on theft, though...
A justification that oh-they-already-offered-ICMP-so-I-took-advantage-of-this-service probably doesn't stand up to they-hacked-my-network-and-stole-the-Internets!
That said, no, I wasn't able to find any concrete whitepapers on the legality of ptunnel.
I know how to do this in Windows and Linux, but not really sure how to go about it on Android...4.0.4 to be exact.
What I'm trying to accomplish is to have both active, with the 3G/4G handling internet-based activities and the Wifi handling local network access.
Why? Basically my home internet is horrible however I have some services/shares on my LAN that I want to access on my phone. And I can't switch between them, not an option. Because many times I'm wanting to take a picture from my file server (Accessed over Wifi) and then upload it to Flickr (Accessed over 3G/4G).
In Windows it's setting the gateway metric, and I would set the connection with the internet with the lower metric while the LAN-only connection gets a higher one.
I'm not aware of any way to do this on any Android - I would imagine it requires a heavily modded ROM.
You could of course tether a Windows or Linux computer on your network to the Android and implement gateway metrics from that end, in order to copy photos from the LAN server to the Internet via cellular.

I'm agreeing with him ^

Ask Cyanogen, if he could do such a thing, afterall, he has been hacking/modding Android since it's inital release. If anyone can help you, it's him... Sorry dude.
While I've never tried it, you might want to try setting up a DHCP reservation on your LAN that DOES NOT provide a gateway. This should allow Internet access using your egress connection while still allowing local LAN access-at least this is how it works for most computers that are multihomed.
I want to prevent my carrier from knowing that I am using CM11's native Hotspot or Tethering features. I know that they can look at the TTL of packets or analyze the traffic (Windows Update, Steam) to detect this. I have a subscription to a VPN service, Private Internet Access, which has an app on Android. If I enable the VPN mode of this app, will all the Hotspot traffic be routed through it, completely invisible to the carrier?
Searching showed me some conflicting answers on this, with some people saying to run it on the tethered device, and others saying to run it on the phone. I am thinking running VPN on phone, as the packets should appear to originate from the phone, rather than something 1 hop behind it.

To the best of my knowledge, they could easily know that you are connecting to the VPN tunnel as it utilizes a certain ports. However if it's correctly set up and utilize a secure protocol, all your traffic will get through the VPN and your ISP won't be able to decipher your online activities and your connection type or make sense of your internet traffic.
In other words, you may be using the VPN to connect to websites A, B, and C and send all sorts of interesting information to those websites; or send email; or whatever. Your ISP can see none of that. All they can see is encrypted data that they can't decrypt. So they know you're using a VPN, but they don't know what you're using it for.
Hope it could help.
As per title, some extremely vile phone companies do not allow us to tether, even though it is our allowance which we have paid for after all.
But how do they know that we are tethering? I presume there must be some software way to hide the fact that some internet data is diverted to another device? How do firewalls do it? You may have 100 PCs and laptops and phones in your house but everyone outside your house sees all your devices as a single IP address - it is your firewall that receives the incoming packets from the internet and distributes them internally. Now I know that it does this by "hiding" the internal IP addresses somewhere in the headers, maybe, so that would be a tell.
If anyone knows a proper way please let me know.
Many thanks
I am trying to figure out how to best tether my phone without my carrier throttling me down or detecting this and getting some exorbitant bill.
Both of these things are important to me but I am trying to find a balance between shielding my tethered traffic while also:
1. Not killing my battery so quickly
2. I am concerned about a notification that I am overloading the CPU on my device.
Equipment\Software:
Samsung Galaxy S9 4 GB RAM w/o Root
SecureTether (Google Play Store)
NordVPN (Paid Subscription)
Major US Carrier w/ Unlimited Data
Dell Inspiron 5559 (Only device tethering to phone)
Here is some of the background:
I get a notification on my phone, no matter how I set things up with Secure Tether and NordVPN either running on my laptop or on my phone.
"Some appications or processes are overloading the System (CPU) and need to close.
How serious is that message?
Critical to protect device or more just a power consumption or load bearing metric?
I keep my phone plugged in when I'm tethering 99% of the time so the power consumption doesn't bother me, but I want to make sure I am not doing something that is detrimental to the phone. Everything looks like it's working correctly and the internet works fine and isn't lagging on my laptop or phone.
Secondly,
I want to use my VPN provider (NordVPN) to setup a VPN to shield my my carrier, to be on the safe side that they can not see my traffic and/or that I am not using their metered hotspot connection. This comes with a performance and power penalty so, I know a VPN is a good idea but is it necessary in order for my carrier not to find out I am using something else to tether my device. This is just for some more general knowledge.
Third,
I can use NordVPN on my device or my laptop and both work fine on either device, in both cases though I get the message: "Some appications or processes are overloading the System (CPU) and need to close."
I can tether my laptop to my phone and then connect NordVPN on my laptop and it takes a minute to connect but it does and when it does. everything works fine.
I was skeptical it would work fine because in order to setup Secure Tether you need to setup not only a basic WiFi connection on my laptop but also use a VPN (SSTP-->192.168.49.1:8822) from my laptop to phone, even before throwing NordVPN into the mix, but
Configuration One:
Laptop ---> Secure Tether WiFi ----> Secure Tether VPN (SSTP 192.168.49.1:8822)----> Connect Nord VPN on Laptop ----> Internet. (((Laptop has NordVPN Internet))) (((Galaxy has clear Internet)))
Configuration Two:
Laptop ---> Secure Tether WiFi ---> Secure Tether VPN -----[[Connection Established to phone]] ----> Connect Nord VPN on Phone ---> Internet (Laptop and Phone)
I am looking for some feedback to see if that first configuration is:
First, Masking my Tethered Traffic correctly. I am only shielding my tethered Internet and otherwise my phone is using normal Internet. I only care about my carrier not seeing that I am tethering my laptop essentially.
Second, taking some of the load off of my phone by not running both services (SecureTether and NordVPN) on it.
But then I thought, if my carrier is seeing a lot of VPN traffic and some clear traffic that might look worse, because generally when you run a VPN on your phone everything runs through it, so with half and half traffic, they may suspect that I am tethering something but they wouldn't be able to necessarily prove it.
But just raising red flags might be enough to warrant a closer look at my account, so it might just be better to run NordVPN on my phone and send all traffic through it.
I only really have this one device connecting to my hotspot, one laptop so it isn't like I have 5 devices each running their own VPN and probably creating more work for my phone with constantly open VPN connections. With one device there has to be an open VPN connection somewhere device/computer and it doesn't matter where it is because it's the same amount of traffic/bandwidth used up anymore, it's just a matter of where it is.
With multiple devices it would be more advantageous to run a single VPN connection on my phone and this generates less traffic/uses less bandwidth?
Am I correct in assuming that with 1 device this first configuration takes some of the load off of my phone because it is just passing data through rather than running the VPN service itself.
Either configuration works for me, I would think that Configuration 2, that is, connecting\running Nord VPN on my device would be a better option from a security standpoint and it simplifies things because:
A. Any device connecting to the hotspot is using the VPN automatically.
B. All of my phone data, hotspot or not is being sent through the VPN.
However, the // [major [/I ] // downside is that power runs through your phone like a sieve and the load on the CPU is increased.
I just got this S9 a few days ago and I am switching from iPhone to Android so my depth of knowledge isn't developed enough to where a reliable instinctual of how this device handles, so I'm sorry is this seems redundant.
Sorry for the length of this post, I got more nuanced than I thought I would but I wanted everything to be clear and maybe this will help someone else along the way.
Any input you have would be greatly appreciated.
