Internet sharing question

I tried to play online game on my pc using the internet sharing from my Touch Pro2, but I got an error that said I am behind a firewall. Any solution for this? I tried using wifi rounter in the rom, didn't work either.

Moved as not software release.

Most 3G networks use NAT, which gives you a form of firewall to give you an internal IP Address, and then translate that to one external IP Address.
Basically lets one IP be shared by loads of users, but it also means that you appear to be firewalled for most games.

Standard DHCP is ON SHUT iT OFF
Standard on WinMo DHCP is ON and I hate it for obvious reasons!! Port forwarding and DHCP is a #%$&^@. Therefore I used S-K-Tools to shut it off
Then I installed Schaps Network Plugin,
http://www.allshadow.com/files/Schaps_NetworkPlugin_1_0_30468_1.CAB
and am a happy camper now! I do know I can use S-K-Tools to see the Network in Explorer too, though I already had Schaps Network Plugin installed, before I stumbled over sk-tools...
By the way I recently posted a thread here on xda-developers with this info;
NbtstatCE
Nbtstat for the Pocket PC. Written in Embedded Visual C++. All versions of Windows CE have a file explorer which can not view windows shares easily. Nbtstat allows the user to view netbios shares on all IP addresses in a subnet.

Maybe its of use to you too. Have a nice day,

So there is no way to solve it?

Tethering question...

I recently read in a post about whether AT&T can tell if you are tethering. This is the response that another user here posted:
thekurrgan said:
Truth: They can tell you are tethering via ANY conveyance that uses IPNAT.
If it uses IPNAT, then the TTL is reduced by 1 since there is another hop. This is how they tell. This little bastardly monitoring technique is deployed on all "enhanced backhaul" sites and is slowly being added to the rest of their towers that are UMTS or better. A simple defeat is using a proxy type of program.. at that point there is absolutely no way they can prove you are tethering, since all packets actually ARE originating from the phone. I personally installed a squid server and set my devices to use it.

My Inspire is rooted, running CM7, and I tether very seldom. I am however going to be traveling soon, and will probably be tethering much more often. Can someone kindly tell me how to set up this "squid" server, or point me to a guide somewhere? Is it an app for the phone, a tool installed on my laptop, or a combination of both? This all sounds pretty foreign to me, so any help would be appreciated..
Thanks in advance..

Thanks for the reply. I checked out that site earlier, and it was way over my head. I also noticed that you mentioned SSH Tunnel but you edited it. I actually installed that already, but have no clue how to set it up. By looking at both links, I'm assuming I need applications installed on both my laptop, and phone. Am I correct in assuming that the host name I need to enter on SSH Tunnel is the name of the squid (or other) server on my laptop?
As far as Squid goes, is there anything else out there that is a little more novice friendly in terms of installation?
I'm beginning to think this whole thing may be a little over my head, and should just tether sparingly. Guess I'm a little paranoid..

I realized SSH Tunnel wasn't much of a help so I removed it.
What the unnamed person is talking about is basically you need to have your phone point to a proxy for apps that access the mobile network.
Whether AT&T knows rogue tether users by non-ATT APNs or natted IP bounce, proxy will hide the usage and make you anonymous.
So,
You need to configure your phone to point to a proxy. Since Android doesn't have proxy features, you need to modify system files (don't want to do that) or install a proxy app (like ProxyDroid) to point to a proxy server (in the unnamed network guy's case, a caching proxy server running Squid.)
Now the question is do you have a proxy that you can point your phone to?
I've noticed PDANet tethering app (v 5.01) for iPhone now has hide usage feature. Hide usage feature is not yet implemented for Android version.
IMO, if you use the tethering sparingly, you will be ok.

How to get around wifi host's restrictions?

I'm using my transformer at school and the school is providing wifi to its students. But there are apparently some odd restrictions associated with it. No app of mine is allowed to access the internet with the exception of browsers and also I'm not allowed to download anything (it just says "download unsuccesful" no matter what I download or from where). I've tried to look for a reson for this and I found out that it might be some firewall settings on the computer that is hosting the wifi, I also asked the school's IT guy and he said that it's likely to be the reason. But the thing is that all the people with computers and iPhones can use applications that use the internet with no problems at all. This makes me think that the wifi host regards me as dangerous or suspicious for some reason, and because it does allow computers and iPhones to use apps that access the internet and are allowed to download files, I think that it might be fixable. Perhaps there are some particular settings that make the wifi host's security to regard me as dangerous and doesn't allow my apps to go to the internet. So what do I have to do for my apps to be able to access the internet and to be able to download files? I really want to know this, because many of the useful apps require internet and by not using them I'm not taking the full advantage of the device. I should also mention that my tablet is running 3.2.1.

But have you tried asking them about letting you use your "netbook" on their netbook. What's the worst they can do? say NO TABLETS ALLOWED? Because unless they know your exact MAC address, they probably won't be able to do anything about it. In my old school, I brought up that I would like to connect my windows mobile device to their network (when I was using it as an mp3 player) and they said sure (they had terrible firewalls which blocked most every site that was fun). Sometimes, the best kind of hackery is the social kind.

I guess his telling you to ask for permission to use your netbook on their network.

Well first of all I'm using a tablet running android 3.2.1. And I'm kind of confused by your use of the word network, because I said that I can use the school's wifi network for students, but only to some extent, meaning that none of my apps with the exception of the browser are not allowed to access the internet e. g. android market, google translate don't work, they just say that they are unable to connect to the network or something similar. Also downloading any file from anywhere is not allowed, it says download unsuccessful. But iPhone user's apps work perfectly fine. From this I concluded that there must be something about my tablet that makes their security think my apps are dangerous and therefore blocks them, and that because there is no such problem on iOS, I thought that the might be something wrong with my end, and that it it fixable. And my question was what do I need to do to fiz this? I hope that clarifies my point.

yes, thanks, I was kinda in a hurry when I typed that

Ask your school's IT department. Network configurations can be quite complex, and without knowledge of how or what they're blocking- it's hard for us to help. IT would know the issue better, or at least give the explanation as to why it isn't working. For instance, last year at my college nothing but computers were allowed to connect to the wifi. Such control can be done on the network side, and it may not be your tablet's fault.
Have you any friends with an Android device, or better yet android tablet?

I did ask the IT guy and he said that he has no control over the security settings, because it's a network across all of the schools in the city, not just the school in which I am.

Hey, I've tried using dropbox at school and then it says "cache access denied", maybe that can somehow clarify my problem.

That's only to allow installing apps not from the Market (sideloading). It has nothing to do with an app working or not.

Haven't you ever heard of proxy and content filtering?
Schools often set up proxies to restrict certain sites and content from working on their networks. They do it for a variety of reason, including bandwidth conservation, content filtering, network security, etc.
More than likely, they have blocked anything that they deem unnecessary. That means that probably only port 80 is allowed (the http port), possibly a few others for https, pop3 and imap for email, etc.
However, if you're a more advanced user, you can probably bypass right past all of this stuff by setting up your own proxy, or using encapsulation (like nstx or icmptx) to bypass their proxy by encapsulating other services inside DNS or ICMP traffic which are usually allowed to bypass the proxy at school. Like I said though, these are advanced techniques and require you to research and set it up yourself.

No, I do not no anything about proxy or content filtering, but I remember when I was connecting to the wifi network of the school I was asked to configure the proxy settings by putting some ip address ( I presume that it is an ip adress because it looked like one) and writing 8080 in the port field. If I didn't configure it like that, the internet would simply not work. Could you please tell me where I could educate myself about bypassing proxies or is i a matter that would require a very long time to learn and a lot of prerequisite knowledge?
And by the way, are you sure that this could be done on a tablet? All of that fiddling around seems to require a considerable degree of control which android may lack, or would rooting give me that control?

OK yeah you are going through a proxy then. The good news is, that because you have to configure it manually, they probably aren't using transparent proxy which can make it easier to bypass.
Getting nstx or icmptx working natively on Android should be possible in theory as both are lightweight and designed to work in Linux... perhaps it can be made into a module that can be activated/deactivated with a shell script, or added to a custom kernel.. obviously this would require a rooted tablet to accomplish.
The other required part of the equation is a computer accessible from the internet, which you can set up install a DNS server and nstx on.
If you manage to get it all working correctly, set your home IP address as your proxy instead of your schools proxy, and you should be able to get through. It should also work to let you access the web for free at places like Starbucks or at hotels where the web is normally routed to a site where you have to pay for web access.
Good luck!

That sounds awesome maybe you could make the app id buy it

I found two apps on the android market : proxydroid and ssh tunnel, do you think they would help me to bypass the school's proxy?
And by the way, how legal is this business? I mean I doubt that the school would send be to jail for using google translate but I'm still curious.

Legal issues are a potential problem, but its doubtful it would ever be a problem at school. Setting this up on your tablet certainly isn't illegal in itself, but if you're stealing wifi that you would otherwise have to pay for, you CAN get yourself in quite a bit of trouble if you get caught.

Ok thanks, wifi network in the school is free for all students so I should be ok. But what about those apps I mentioned before?

And how would I protect myself from geting caught and what is the likelyhood of me getting caught? Can they immediately notice it if someone's trying to bypass their firewall or not? I should point out that the it manager in our school knows quite little about the sexurity system or ao he told me when I asked him whether my problem is somehow connected to their security settings, but the network is not pwned by the school, it's owned by the city and it is present in many schools beside mine, so I think that they might take their security seriously. So basically what I am trying to say is that if I investigate this matter, come there and bypass the proxy so that the youtube app works, is it likely that I am going to get caught, and if yes then what are the ways of minimising the risk (please bear in mind that I have not experience in this)? I'm asking this because I think it's not a very good idea to just walk in and hack the network without any experience and expect that there is no possibility of getting caught.

No neither of those apps are really the solution to your problem. There isn't currently an app for Android that will set up encapsulation like I'm talking about.
And yes, your IT manager at school "might" be able to catch you, but only if he's specifically looking for it. What this basically does is encapsulate your regular IP traffic inside DNS packets (or pings for the icmptx method), which are generally allowed to pass through firewalls and content filters. Basically, it is detectable if your network administrator is looking in the right place and knows his stuff. There would either look like a constant stream of DNS requests from a particular IP on the school network, or a constrant stream of ICMP traffic (pings) being sent out. However both ICMP and DNS are normal for any network, so its also equally possible that the administrator never notices that anything is wrong at all...
Some more sophisticated networks may employ transparent DNS or transparent proxy, which would make these efforts much harder. Transparent proxy is able to intercept any traffic and force it through the proxy at school, while transparent DNS is able to intercept DNS traffic and force it to use a specific DNS server regardless of settings on your tablet.
Like I said in the beginning though, these are really advanced networking tricks that certainly aren't easy to set up, even when all the components are readily available.. its possible they haven't even been attempted yet on an Android device. That said, it shouldn't be difficult to port either icmptx or nstx over to Android for somebody with the requisite programming skills.

Using it at School, Want to Have Some Privacy

So my school just recently said we can use tablets and laptops in class and around the school. They are willing to allow us to connect to the school's WiFi, but we have to give the dean the MAC address for our device.
I'd like to be able to keep some privacy, even though they say we have to waive our right to privacy if we decide to use electronics. I guess I'm looking for a few apps that can help me achieve this. Maybe a browser with an incognito feature like Chrome, or something that can cover what I'm doing online.
I also wanna know if there would be any way for me to access thinks like Facebook, Twitter, Youtube, Google Music, etc. through their respective app if the website is blocked.
If push comes to shove, I guess I could just tether with my GNex, but that would require an extended battery, which I would like to not have to buy.

Have you tried using the incognito tab option on the stock honeycomb browser?

Unless you are using some sort of vpn connection or encryption you have no privacy. I'd suggest remoting into your home desktop using splashtop or teamviewer and doing all your browsing on your desktop if you are worried about privacy that much.
They can see everything you do since it's a shared connection and they have access to the gateway and internet logs.

They are probably running a transparent proxy with logging (I would be if I were the sysadmin), so the incognito tab won't help.

That does not do anything with the connection. It just dont cache anything in your browser. So that noone borrowing your computer can see that you have been watching porn.
But to OP: Get a vpn connection. Only way to get privacy on a wifi system.

whoa whoa whoa man... "incognito" has nothing to do with what you transmit online. it only prevents them from seeing what you have already done if they took your device
what you need is a secure VPN like goldenfrog.com, or use a secure proxy server. anything that puts a layer of encryption between you and the server will block out any man in the middle
noobs these days... incognito has NOTHIGN TO DO WITH WHAT YOU TRANSMIT DAMMIT
if you want, use opera and turn on the "turbo" feature. that will create a link to the opera servers and deliver compressed content. meanwhile, it will make it impossible for the school to decrypt anything it intercepts.

Nope, opera turbo is a plaintext connection so still can be viewed, the only option is https for everything or vpn/ssh tunnels

Ok thanks for all the replies. I guess the easiest thing would be to tether with my phone. (Hopefully Verizon doesn't freak )
I guess I can try setting up a VPN (no idea how). I think my friend tried to, since he owns a bunch of servers, but the school blocks almost every port.
Could using a vpn connection be considered
using Proxies, Caching Servers or any others means to circumvent restrictions placed on
the school’s IT network and internet access

Yes but I would bet the reason why they want the MAC address is for WIFI access. You could spoof someone else's MAC but school's aren't known for having hard facts before disciplining students. If they think it is you, you will get in trouble.
I would recommend using TOR if you want to protect your privacy. Download Orbot from the market.

Considering the schools budgets these days, you probably have nothing to fear as far as privacy goes.
Sure they are logging your wifi usage, but no one is monitoring it! All the logging allows them to do, is to look at where you went and when AFTER they have a reason to start looking.
Unless they hired someone specifically to start monitoring students, no one is ever going to look at your logs.
Sure they could put in alerts to let them know when any user goes to site xyz, but odds are they simply have blocked it.
One of the main reasons they are logging things is if say perhaps a teachers online grades were 'hacked', and the IP was traced back to their own servers, they'd have a way to identify which user was using that connection.
Many ISPs already log your internet access as well, but it's at such a low level that no one looks at it (though there are privacy laws to prevent them from looking directly in those cases).
Bottom line.. is if you're not doing anything illegal (torrenting, sending nude pics of yourself, harassing other students via text/email) then you have nothing to worry about, and odds are you won't even be noticed.

I partially agree. If you use the schools network for normal stuff you shouldn't have anything to hide.
But Co-students are a great security risk. Both willingly and unwillingly. In these days with loads of malware floating around jumping from computer to computer via security flaws in networked devices. Students may also try to hack your device just for fun.
If you have sensitive data you really should encrypt your traffic in one way or another when connected to a network with unmanaged and unknown devices.

Bored teachers/faculty get up to practically anything and snooping on students is apparently a great sport. Everywhere that has a computer lab has someone doing IT and just think about that for a minute...someone doing IT at a high school, the personality of that person. You don't have to be doing anything illegal to get into trouble with your school. A casual google will reveal all the lawsuits students have brought against schools for violating their privacy. Do yourself a favour and use Orbot.

it is great fun, but also remember that code of conduct that you and your parents sign at the start of the year states that we do have the right to make sure you are using the internet provided by the school for school purposes only

Can't you use 3G connection from your phone instead of the school WiFi?

As far as getting on facebook if it's blocked....
If you type httpS://facebook.com it will usually let you in. They have blocked several websites at my office, but I can still get into them using this trick. Sometimes, you will have to add the "S" after navigating through the websites, but still will let you get in. So, just use your web browser (not the facebook app), and type s. I believe most people don't block secure websites.

The internet provided to the schools by tax payers and/or tuition you mean. You have a wretched problem that is rampant in American schools: you think you own the school's resources. They are owned by the community.

So the administration announced today the final policy and they won't be allowing WiFi access until next September because they want to expand the network. I'll probably just be tethering for the mean time.
Oh yeah, there's only 2 IT guys in my school (lol). One stays in a glass room in the back of the computer lab, and the other comes to classrooms to install projectors and crap.

asked to dowload Avast Antivirus when entering an url

every time i enter an url in Opera, Dolphin or any other browser, i am asked to download "avast_free_antivirus_setup.exe"
I have a optimus 2x using temasek ROM and Kernel. What i should do to solve this problem?

Does it happen on wifi, 3G or both? Maybe a DNS issue, try typing "74.125.226.69" as an address. Thats the IP for Google's homepage and should bypass any DNS server. An infected exe file on android is harmless, but could infect a Windows system the second you plug in your phone with a USB cable.

Do a reset, sounds very strange and check for your problem after every app you have installed. IMHO anti_virus_ software with phones is useless. Problems occur with trojans.

the problem desapeared. Maybe it was after clear history, but it desaperead even in Opera, and i did not to fix that... i have no idea what happened

This is kind of interesting to me, I've been looking for antivirus software for my phone, as a previous poster said it will do no harm to your phone, but could harm your PC once connected.
I think there is a gap in the market place for a true antivirus software for your phone.
My 2 cents!
