[Q] Which ports does the Android Dropbox app use? - Networking

I use a rooted Android phone and the app ASProxy to use WiFi at work, where a proxy with authentication is required. ASProxy lets me transparently proxify traffic from specific ports, e.g., 5228 for Market auth.
In order to make the Android Dropbox app work when using ASProxy, I have to know which ports it uses. Could anyone help me with finding this out?

.pac proxy

anyway to use a .pac proxy URL on android?
don't think you can do this,think the phone os not able to understand, why do you need to use pac files?
Sent from my GT-I9000 using XDA App

I know this is old, but this is an ongoing problem and I figured out how to use a .pac proxy file! After reading about proxy's and what .pac files are, I stumbled upon a little hint and after a little tinkering I was able to use my work's wifi that uses an auto-config .pac file and my phone and tablet has full internet access with browser, apps etc including Netflix for example.
Here are the steps you need:
1) Your phone has to be rooted to take advantage of the proxy apps on the market, I personally use ProxyDroid, which is free and has a feature to bind certain proxy profiles to automatically turn on when a certain wifi network is connected.
2) Usually there is an option that gives you an http proxy pac file to manually input to your browsers or what not, so whatever the link is, put it an active internet browser to download the pac file (an example of the url with the pac file would be something like http://internet.xxxxx.com/proxy.pac)
3) Where ever you download the pac file, open it with notepad or wordpad and this will reveal all the proxy info you need in order to access the proxy enable wifi. What the ProxyDroid app needs from the PAC file is the Host url and Port number. When you open a PAC file in notepad, you'll see something like this near the top along with a bunch of other things under it:
"Cisco Remote Envelope Service
if (dstHost=="internet.e-mail") {
return "PROXY internet-x-x.xxxxxx.com:9090""
- So in "Host" under Proxy Settings in the ProxyDroid app you would input: internet-x-x.xxxx.com
- For the "Port" you would put input: 9090
4) After inputting those 2 pieces of info into the ProxyDroid app, turn the wifi on for your Android Device then enable to ProxyDroid app, you should able to connect to the proxy enabled wifi!
*Some notes for the ProxyDroid app.
- It allows for Authentication, but since my work wifi does not use that, I'm not sure how it would work
- For Proxy type, I set it as an HTTP
- I binded the specific proxy profile to my work wifi so it would ProxyDroid would automatically enable when work wifi was detected
Hope this bit of info helps other that have Android devices and were unable to use a proxy enable wifi to finally access them. Hopefully in the future, Android will make using proxy and pac files a lot easier like how it's done on the ipad where they allow you to manually set up proxy settings by having the device download the PAC file.
I've tested and this works on both a rooted AT&T HTC Inspire and a HP Touchpad running CM7 Alpha

Check out autoproxy on the market. It's my app and it's new. It's the only app that supports proxy.pac proxies directly. Just put the address to the file there, and click connect. It will also auto-connect when you're on the same network again (and disconnect when you're off it) so it's set and forget. It will allow you to use any apps, as long as the port is not blocked by the proxy.
Dtothesquare, that technique will work for simple proxy implementations but some organizations have a cluster of proxy servers that may serve different clients (closer to client without using anycast) or destinations. For example, a proxy server may be set up to just handle *.com while another could handle just internal hosts. It can also be used for sending clients to an alternate proxy server should the primary one be down for some reason.
Our proxy server has ACLs that only let it proxy certain URLs and returns an error if it receives something that's not allowed on that server.

[Q] Proxy Trouble !!!

I'm behind a proxy in my college....in order to connect to internet I use transproxy 3.08b on my phone....all apps work fine excluding the Market and Gtalk.....
Market surfing works bt installing apps doesnt work cos it is stuck at the downloading part....
Similarly Gtalk shows an "unable to connect to server error"
Gmail works fine...then why do the former not work..
Is it a port forwarding problem?
I think the ports used for above might be blocked by my proxy....Is there a way to get around this?

Is there nobody here who is in a college or a university like me???
Got my answer but the problem still persists
I found that my college proxy is open only on the port 8080.
so google market downloads and Gtalk dont work which use the ports 5228 and
5223,5224 respectively.
I came to know that Google authentication also uses port 5228 and I'm able to sign
in with my google account using my phone [using transproxy...thanks to Daveba for
such a useful app] then why dont the market downloads work (using the same
port)
Pls share ur knowledge on this. thnx in advance

[Q] Setting up a VPN that my xoom can access.

I want to set up a VPN at home that my xoom can access. I tried a simple PPTP with dd-wrt but I can't seem to access or ping anything, even though it connects. I want to do this so I don't have to forward SSH, RDP, and other ports that expose my stuff to the outside world.
At home I am running a DD-WRT gateway with a linux server as well as a Windows Server 2008 VM behind the gateway, any could host the VPN service.
I don't need instructions on how to set up the VPN, but advice on what is compatible with android's built in VPN support.
Thanks in advance for any input.

The windows vpn service works fine for me
I was under the impression I needed to set up a domain to use the included windows VPN service, and I wasn't looking to set up a domain.
Is this an incorrect assumption?

Here's a link to getting OpenVPN working. Must admit it looks like it's not for everyone.

That was not necessary for me. If it is a requirement, it is specific to Windows Server edition
I have a Windows PPTP VPN that my Xoom can connect to. You do not need to set up a domain.
Unfortunately there is a bug in Android that makes it lose connection to the VPN after a few minutes/seconds.
See here:
http://code.google.com/p/android/issues/detail?id=4706
I just bypass androids native VPN and use Neo Router free. Available in the market. You just set up a Neo server on the computer you want to control and use the android app to open an encrypted connection to that computer. You can set up the app to forward any ports to the computer running the server. Works well. Right now im running splashtop remote and plex using it so i dont have to port forward the ports for those apps in my router.
Thanks for all the input. I am working on OpenVPN. I almost have it working (I already have my router set up for OpenVPN, just didn't know I could use it).

Setting up Global SSH Tunnel on Android

For anyone interested in data security the ability to encrypt network traffic is obviously important-- especially in light of the myriad of recent well publicized reports of private and government electronic snooping. It is also relevant to mention that to date no one has come close to cracking "TwoFish" encryption which can be used by SSH. With this in mind, consider the following tutorial which describes a method for encrypting all 3g, 4g, and Wi-Fi data, thus beefing up phone and personal data security.
Setting up a global SSH Tunnel on Android phones
This tutorial assumes the reader possesses a fully configured SSH server and rooted phone. In lieu of a server, (eg., the reader only has only a Windows-based operating system), research into CYGWIN is recommended. I use CYGWIN to run my SSH server and I have found that it is the most robust option for Windows users; however, setting this up on Windows can be a daunting task.
Setting up global SSH Tunnel on Android
1. Download 2 apps from the Google Playstore: ConnectBot and ProxyDroid
2. Install ConnectBot and ProxyDroid on your phone.
3. In ConnectBot set up Port forwards for your SSH connection. For "Type" field use "Dynamic (SOCKS)." For “Source Port” use 56001 or any local port not being used. The reasoning behind using port 56001 is this: System Ports (0-1023), User Ports (1024-49151), and the Dynamic and/or Private Ports (49152-65535)
4. Open ProxyDroid and configure as follows:
Host: 127.0.0.1
Port: 56001 (or the port you chose to use in step 3)
Proxy Type: SOCKS5
Global Proxy: Check the box
The above procedure accomplishes several things. First, ConnectBot remotely connects to your SSH server. Next, the ConnectBot connection forwards to the local port 56001. ProxyDroid then redirects all network traffic through the localhost on port 56001. Once you are connected through ConnectBot and ProxyDroid is activated all of your data will be tunneled through the encrypted ConnectBot session. This is an excellent way to set up a global proxy because it does not require manual configuration of any applications to connect through the proxy. You can test the functionality of the connection by opening up your phone browser and performing the Google search: What is my IP. If the proxy is functional you will see the WAN IP of the network of your SSH server. Additional and more thorough testing can be done with packet sniffers such as WireShark.
An application called "SSH Tunnel" is an alternative to accomplishing the above. However, I find ConnectBot and ProxyDroid is more elegant and gives better control-- not to mention being more sophisticated/chic. When correctly performed the ConnectBot and ProxyDroid method encrypts all 3g, 4g and Wi-Fi data on your phone. This is obviously useful for phone access of sensitive materials especially using unfamiliar or alien network connections. With the current proliferation of identity theft via electronic snooping on mobile devices I do not advocate using cellular phones for any banking or electronic transactions without setting up a robust and reliable encrypted connection.
I'm having trouble with this exact setup on Android 4.3 with DNS Proxy (proxydroid) enabled in China. When DNS Proxy is enabled, no traffic will come through at all. If I disable DNS Proxy, it works but without proxied DNS requests, I can't get to Youtube/twitter/FB.
Any ideas?
SSHTunnel for 4.2.2 is a much better alternative than running 2 separate apps and I still use it on my 4.2.2 tablet. But I don't want to downgrade my phone to 4.2.2 just for this

Unfortunately, I have not done any testing with android 4.3 yet so I'm not sure why the dns request wouldn't be proxied. I'll look into it and get back to you.

So I finally had a chance to upgrade to 4.3 this week. I tested the dns proxy with proxydroid and it seems to be working fine. What rom are you using? I'm on Sacs rom and I would highly recommend it. Heres the link:

I have been looking for a new way to setup SSH tunneling since the app "ssh tunnel" from the Google Play store stopped working with Android 4.2+
I can't wait to try this out..
I have two phones both SGS4's one running CM 10.2 and the other stock on 4.3 so i will try both of them out and report back here how it works out.
Thanks again for the tutorial!

Thank you Dr.Tautology
I was searching a big time for the solution you gave me.
First I was using SSHtunnel app from google play and it worked on my note 3 SM-N9005 (rooted) with jb 4.3. After upgrade to 4.4.2 kitkat (rooted) I could connect but there was no changing to my home ip in the browsers that I use with surfing by example to whatmyip . I also have a tablet "nexus 7" 2012 version upgraded also to 4.4.2 and on this device SSHTunnel is functional and the ip is changing??? I did not understand. Now I was searching for alternatives for my galaxy note 3 and I've found ssh connectbot and proxydroid. After I added the settings that I always used with dyn socks5 port 11723 on both programs.... -> connection to my DD-WRT router (with connectbot) was also possible. I also booted proxydroid and again after running chrome or firefox I still had the same ip so it didn't work.... Now I've found your post and read that the socks5 port must be above 49152. I changed the ports on both programs to 56001 in ('connectbot and proxydroid) and BAM! Connected with my home IP from outside my home :laugh:
The weird thing is that it worked on JB 4.3 with socks5 port 11723.
Now my woking SSH tunnel config -> Host = home-ip:7500 (default port = 22 in DDWRT)
user to connect to DD-WRT router = Root
password = Router password
dyn proxy socks5 port = 56001 as you suggest.
I have an app from my isp that I only can use with my home ip so I had to be home and connect by wifi. Now it's possible again with tunneling
Now the only thing that I have to do is thank you. :victory:
Never thought that the port number should be the problem.
Best regards DWroadrunner
I managed to set this up using SSH Tunnel for android. However I would like to use SSH Autotunnel as it's supposed to handle network changes better and is also more light weight. Does anybody know what type of private key this programm accepts? I have had no luck using putty keygen and the id_rsa I created in ubuntu does not seem to work either.
Glad to help!

Hey DWroadrunner,
That's great news! I'm very happy that my post helped you, as my intention was to provide all the necessary information to do this in one place. It's not always the case that a user port wont work, but unless you are big on port level security it's not easy to determine if/when the port is being used. This is probably why 11723 did work for you, however it's always better to go with a dynamic/private port range. Also, if you want a simple way to improve the security of your ssh server change the default port from 22 to something else. You'd be surprised how many attempts to connect will be made by attackers on a daily basis.
Regards,
DocTaut

Hello,
I've used auto tunnel a handful of times. Just wanted to check to see if you figured out what key it accepts. I will test it out when I get a chance.

Hi, the developer send me a mail saying that autotunnel should accept both private key types. None of them worked for me, though. He also suggested to try and paste the content of the private key into the bracket. I might give that a try. Edit: I can confirm copying and pasting the private key works. But it does not seem to transfer traffic via the the server, at least not the 3g traffic while using chrome. Edit 2: Turns out SSH Autotunnel does not use a socks proxy. Therefore secure browsing is not an option. The app is for secure pop3/ftp-server/smtp-server connections only. Thanks go to Matej for his kind support.
I've been using OpenVPN but I'd prefer to use ssh, as I have several ssh servers around the world, plus their pipes are bigger than my home line I have openvpn running on.
I have yet to get SSH Tunnel (apk) to work reliably; it randomly stops working and it's just a dead connection.
Using ProxyDroid unfortunately requires me to launch ConnectBot, connect ssh, then start the proxy. It'd be nice if ConnectBot could bring up the connection automatically, or ProxyDroid could do it. What I do right now is VPN unknown wifi connections and I can automate that with Tasker. I might look to see if I can automate connecting with ConnectBot then enable the ProxyDroid connection.
You can use ssh tunnels also with Drony if some proxy with authentication is involved. Works also on non rooted devices.

I think so, it's just firewall settings etc.. Unfortunately for me, I need stuff that doesn't support SOCKS so I've gone back to looking into a faster OpenVPN service.
But this is good for browsing and things that use http etc.

Do you have to login to the proxy or is it an open proxy? If it's open, you could see if you can find a OpenVPN server that listens on 80 or 443. Then use any OpenVPN client on Android and you can add/update config to match the directions here: https://openvpn.net/index.php/open-source/documentation/howto.html#http
