General :: Set Up VPN Connection Between Linux Mint 10 PC (server) And Nexus 7 (client)
Dec 1, 2012
I'm trying to set up a VPN connection between a Linux Mint 10 PC (server) and a Nexus 7 (client).
All I'm getting so far is a "Connecting" status from the Nexus 7, followed after a few seconds by a "Disconnected" one.
As it is my first attempt at setting up a VPN (both on the server and client sides) I was wondering if there was a log file generated by Android on the Nexus that would give me a clue as to where I'm going wrong.
A similar file on the server side

I recently switched over from Win 7 to Mint 15 and cannot get ADB and fastboot to work for the life of me! On Windows, I just downloaded and installed the Android SDK and had no trouble using ADB and fastboot to mod my phone. It is proving to be much more difficult on Linux.
I've searched Google, Linux Mint forums, and these forums; tried following numerous guides, and still my comp can't recognize my phone. Every time I type in "adb devices" I get "List of connected devices" followed by a blank line. No question marks and certainly no connected devices. "lsusb" shows my HTC One S as connected so I know it's not my USB port.
When I plug in my phone, I get an error message, "Unable to mount Android Phone Unable to open MTP device '[usb:002,005]'" and then a file explorer window opens displaying my phone contents anyways. Not sure if this could have anything to do with it but I thought I'd mention it.

I have a nasty problem with the adb and my Galaxy Nexus (CM10 nightly-20120926). The ADB seems not to work properly. Every time I start my app within Eclipse it gets installed on my Galaxy Nexus and the LogCat window show some output. So far so good. But suddenly ADB stops writing messages and the "Console" windows shows a lot of messages like:
Code:
[2012-09-26 21:01:15 - DeviceMonitor] Adb rejected connection to client '2930': closed
[2012-09-26 21:01:15 - DeviceMonitor] Adb rejected connection to client '2459': closed
[2012-09-26 21:01:15 - DeviceMonitor] Adb rejected connection to client '2459': closed
[2012-09-26 21:01:17 - DeviceMonitor] Adb rejected connection to client '2610': closed
[2012-09-26 21:01:17 - DeviceMonitor] Adb rejected connection to client '3079': closed
[Code .......
From now on the ADB does not output messages any longer. I have to reconnect my Galaxy Nexus to my USB-Port to restart the debugging.
And some messages I generate by using "System.out.println();" are never displayed also!
My onCreate() method looks like
Code:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
System.out.println("ON_CREATE!");
[...]
But "ON_CREATE" will never be displayed!!

I'm experimenting with SIP/VOIP on my Android device (Galaxy Nexus). I'm using the SIP account settings in the stock dialer app, this works fine for dialing/voice.
The issue is there are no similar SIP settings for the stock SMS client... is this simply a feature that was not added for some reason? is there a technical reason why this is not possible? (other third party clients support it) or can the stock SMS client use SIP and I just can't figure it out?

I have set up a VPN server on OSX Lion Server edition.It is using l2tp with preshared key and username/password for login. i(beep) works fine and connects. Laptop works fine and can connect.But...
1. When Iam on local network (same IP segment) I can connect using Android native l2tp VPN connection setup with PSK and user/pass.
2. When I try to connect from external (3G or other WiFi net) I am unable to connect.
3. When I enabe native tether on Android device, and connect i(beep) to the Android AP, I still am able to connect from i(beep).
These three steps tells me it is not a carrier issue, and possibly an Android issue.Kinda like the l2tp connection for security, and also Lion natively does not supply pptp connection.

I have to create an app that allows other devices to connect to my android terminal via wifi, without access point, so my device should become an access point to host their connections. i don't have to share the internet connection with them, just have to make them connect directly to me, then they send a UDP packet, and I have to read it, so on my device will have to be an UDP server after the connection creation. how to manage wifi? any step to follow? my android version is 4.0.3

Part of why I bought a HTC Desire to replace my 2G iPhone was getting away from iTunes - piece of bloat required me to keep a Windows computer around, updating music was pesky, etc.
The plan with the HTC is to sync it over Wifi when it connects to my home network. The system it syncs with is a media server running Linux and storing my music collection.
I've gotten so far to have Tasker start FTPServer on connecting to Wifi, and have built a little script called every 10 minutes by cron that checks for presence of the phone. If it finds the phone, it connects and syncs a folder, then makes the ftp server on the phone shutdown, so it won't reconnect every 10 minutes.
So far, so good (I'll gladly share the bash script, if anybody wants to use. Needs some more polishing, though)
The bit that bugs me is playlists. I can create m3u playlists and copy them over fine, however once they are on the phone, they disappear from the Music folder and cannot be changed/deleted anymore - except by the built in music app. This is quite inconvenient, since I have a number of podcasts that get updated daily and that I'd like to take on the phone, with a playlist showing the newest episodes first. I can make the playlist easily on the computer, however the phone will end up with multiple copies of these playlists, which I can't get rid off.
If there's no way, I'll work around by editing track/album MP3 tags and grouping my stuff together this way, but I'd prefer using simple playlists...

I have a Motorola Atrix2, running Android 2.3.6 on AT&T. I have used Google Talk since getting the phone last December, but for the past week have had trouble.
When I wake the phone I find that I am no longer signed into Talk. My contact list is subdued in grey, a notice appears at the bottom of my chat window saying that the connection with the server has been lost, and my 4G icon has gone from blue to white indicating that I no longer am connected to Google.
I haven't done anything to the phone / settings to cause this. I've tried many things to fix this including: rebooting, hard booting, force stop the application and clearing it's data (cache is always empty), and replacing the SIM. Needless to say none of these steps have worked. I have not tried a factory reset as I have read elsewhere of people trying this with no luck.
As far as I have been able to tell, this problem only happens when connected to my service plan, I have never noticed this happening when hooked onto WI-FI
Having searched online all I can find that might be at fault is the version of Android (the phone originally had 2.3.4 but was upgraded several months ago), and the fact that AT&T has recently upgraded to "true 4G LTE" in my area. I have no idea if either of these are actually the cause of my problem.
Google Talk is one of my two main means of communication and I really need this resolved.

I use an LG Optimus L4 II (e445). I rooted it but then decided I had too much on it and decided to restore to factory settings. It all worked fine. However, when I got to the Google Account sign in page, it gave me the "couldn't establish a reliable connection to the server" error message. I followed every single tutorial I could find online as to how to solve this. None of them worked. Eventually, I re-rooted it (using VRoot) and managed to download an apk of ES file explorer and locate the hosts file. This had one line that shouldn't have been there:
[URL]
From what I can make out, this is the address of google's sign in servers. So somehow (I suspect malware/dodgy rooting program?) my hosts file has been edited to stop me logging into google. Restoring the device does nothing, neither does unrooting/rerooting. When I open up the file in ES (when rooted) and edit out the bad lines, I can't save for some reason- I think the /system folder is write protected.
So I tried to make the /system folder writeable. I used the android sdk to do this (mount -o command) but this did not do anything. I downloaded the mount /system apk and installed that, it did not work either. I tried /pull and /push on the hosts file to edit it and send it back using the apk. I could successfully pull and edit it, but it would not let me push it back. I can effectively not use my phone- I can't use most apps and can't download any.

I'm going to creating an Android App where 4 players can connect together and play the game together, now the connection is most probably going to be bluetooth, quicker and my app wont be using a online server. But I'm trying to work out which would be best, P2P or client server, a peer to peer connection would be good, but is 4 users connected together ok and stable using bluetooth? A client server solution would be the host would turn into a wi-fi hot spot while 3 others connect to that wifi.

I am looking for a way to automate my Android phone connecting to an SSH server when the phone connects to an unsecured wifi network. My understanding is that this is adequate to keep my traffic from being sniffed by DroidSheep (Android), FireSheep (Windows), or other packet sniffers.
I'm using this guide to connect my Android phone to the SSH server: link HERE
Is the Tasker app the best way to do this?
- if yes: how do I trigger the launch of the SSHTunnel when the trigger event (connection to unsecured wifi network) occurs?
- if no: what is a better way?
Note: I did a search for SSH (link HERE) and did not see anything covering this.

I have an application client/server and I want to install this application in differente machines. The server is located in IP_SERVER, listening port 7000. I want to start a cliente in another machine with IP_Y and connect to the server on the different machine.
I've started the server and I've created the socket like this: ... new ServerSocket(7000);
I've started the client and I've created the socket like this: ...new Socket(SERVER_IP, 7000)
But the client did not connect to the server. I've already set the INTERNET_PERMISSION. Any suggestions how to do it? Anybody else have already done a client/server application that communicate between different machines?

Going to grab myself an HTC magic today. Done some searching around and can not wait to finally ditch this POS iPhone.
Anyhow, I'm looking to see if anyone has any info on a mt-daap server and client.
If you don't' know what it is you can look at
Firefly Media Server :: Home Page
it's a clone of the iTunes music sharing service. It allows you to share your music collection over your network.
I have a firefly server setup and share my music colection with all my systems. As well I VPN into my network from work/coffee shop and can listen to my tiny 500GB music colection on my netbook (ubuntu 9.10 btw)
I would love to be able to do the same with my new phone. My curent iphone(jailbroken) has a firefly server that i can share the music from it's ipod side. But alas no client.

I have a simple Java client application (Android app). I have to write a PHP server application which receives a request from the Java client application to write some data to a MySQL database or read some data from the MySQL database. It should respond with a status message (Write failed/success) or the data requested respectively. How would I get the Java client send a request and receive the reply from the PHP program and how would the PHP program receive the request and send the reply? I have googled about SOAP and REST architectures, but looking for a simple tutorial which will allow me to implement this simple program.

I wish to send a list containing objects from server to client and vice versa through httpurlconnection. Elaborating the same, the list contains a set of objects which is defined both in the server and the client. Its just that the server queries a database and sends the object to the client which collects the same and displays it to the user. Please let me know if thats possible and if it is, how would I be able to accomplish that.

I'm currently in the research phase of my dissertation project.My project is a ticket booking system for a mobile device and I have chosen to target Android.I anticipate the need for a client/server architecture with a central server, and so am currently looking at how Android could communicate with such a server. The server would grant the client access to ticketing information, and the client would send information about ticket bookings to the server. I'm looking at Java EE for the server as Java is the language I'm most experienced with.I'm aware that Android comes with java.nio and java.net, as well as some org.apache packages, but am also looking for libraries/technologies that would be possible to use with Android.

I am new to developing applications for android but have developed my first app. I have following questions.
1. Is it possible to create a client server app? I mean the application on one phone acting as server and applications on other phones sending/receiving data from it?
2. Create a wifi network (may be using bluetooth) for the above client server app. The idea being not to use the mobile service provide network but rather a local network.
