hyperboria / android Goto Github PK

Set up Espresso, move the mock data to tests, and start testing.

The cjdns-android app, when it is eventually built, manages the cjdns service and facilitates peering. Running that alone should allow your browser to reach services offered by your peers, and also reach Hyperboria if at least one node in your network is able to reach it. This is however, just a basic use case. The mobile nature of a cjdns node running on a phone comes with challenges, like transient peers as phones go on & off, move in & out of range, etc. but also opens up use cases that aren't practical on stationary nodes. Cjdns-enabled apps can be built to allow such use cases, like an encrypted messaging app across an ad-hoc network. Think FireChat but secure, and requires the cjdns service to be running. The cjdns app will allow other apps to silently kickstart the cjdns service on the device.

This issue is created to discuss:

• Mobile-relevant use cases
• Ideas for cjdns-enabled apps
• How to implement them, whether the current design of the cjdns app can facilitate that use case, and whether the Android platform will support it

Trying to type in the pubkey and password manually sounds difficult, and there aren't a lot of secure copy-paste options. Maybe this project could be useful for the desktop side of things?

It is possible to access http://[fc53:dcc5:e89d:9082:4097:6622:5e82:c654] but not http://h.fc00.org

Need to figure out how to make DNS resolve ipv6 addresses.

This library is used in Orbot and it seems to handle some Android inconsistencies in that world. Perhaps we should use it or port some of the logic when issuing shell commands.

Almost all persistent data in this app need to be stored encrypted. We cannot rely on device-level encryption because it's not always enabled, and only enabled by default on Lollipop+. So we need to implement our own, which unfortunately would require the user to supply a PIN every time we start the app. The PIN itself, must not be stored on the device at all.

I am debating whether encryption should be optional or required. I am leaning towards making it a requirement, because the app holds not only this node's credentials, but also those of your peers. Though this PIN is kind of redundant when device-level encryption is used.

If you are feeling particularly adventurous, you can investigate whether we can implement something that works across devices using private APIs without requiring a PIN from the user. But then it still would require the user to have a device-level PIN set. So my suggestion is do the whole thing custom with NaCl, which needs to be in the app anyways because of wrbt peering.

Upgrade to this and test lists on Gingerbread:
https://github.com/brnunes/SwipeableRecyclerView/releases/tag/v1.0.2

You won't be able to swipe the cards, but it wouldn't crash anymore.

What are those credentials(Alice, Bob...)? And why they are uneditable/unremovable?

Hi, might someone with Android experience compile an APK for a stable version?

This would benefit the project by making it easier for people to install the app.

I just found the meshnet project after someone posted about it on https://www.reddit.com/r/todayilearned/

Perhaps a build script could be written. I don't have much experience with Java / Android which is why I am not simply doing this and submitting a pull request.

Just watch.

We have discussed two ways for Android devices to exchange credentials, i.e. QR and NFC. Both these methods are meant for devices to peer while in close proximity, and require that both have the cjdns-android app installed. Yes, the QR can be distributed across distances, but that's the same as broadcasting the credentials to the world. So I am proposing a more general way to securely exchange peering credentials over distances, and requires only the initiating party to have the app to begin with.

1. The initiating party will click some button from the app to initiate peering with a friend. Something like this URL gets copied to the clipboard. She can send it to a friend via email, text message, whatever.

   http://special.clearnet.server
     ?type=peerRequest
     &protocol=udpInterface
     &pubKey=thePublicKeyOfInitiatingDevice
   

2. The friend receives it and clicks the link. If he has cjdns-android installed¹, the system will ask if he wants to open the link with the cjdns app or browser. Upon selecting the cjdns app, the app will ask if he wants to accept this peer request. Upon accepting, the app generates a new set of credentials for the requested protocol, which gets encrypted with the public key from the query parameters, and the following URL gets copied to his device clipboard. He then emails it back.

   http://special.clearnet.server
     ?type=peerResponse
     &credentials=credentialsEncryptedWithHerPublicKey
   

3. She receives the response URL, clicks it and selects the cjdns app to open, and the app decrypts with her private key and adds it to cjdroute.conf, restarts the service.

¹In the case where the friend does not already have the app, the URL will open in browser, which we set up special.clearnet.server to respond to all requests with market://details?id=com.cjdns.app.package.name, so all potentially new Hyperboreans are directed to the app in Google Play.

What do you guys think? There are some uncertainties around what protocols can be used to peer between two Android devices, and whether in Step 2, he can accept by using a set of known credentials that the app knows about, such as his VPS.

finn's repo: http://h.finn.io/fdroid

This thing is not working at all(tried on One PlusOne with Android 5.1.1 and on emulator with Android 5.1). It's not creating any tun0 interface and it's impossible to connect to any hyperboria sites(even after manually adding public nodes to cjdroute.conf).

P.S. it creates tun0 interface if you run it manually from terminal emulator or adb as root.

In file AndroidManifest.xml

Manifest should specify a minimum API level with <uses-sdk android:minSdkVersion="?" />; if it really supports all versions of Android set it to 1.

We have a standardized format to request for peering and distribute credentials. It's work-in-progress, but they will look something like this.

Peering Request

scheme://host/?type=peer&interface=udp&link=overlay&pk=wrbtPk&metadata=metadataOfAlice&cjdnsVersion=X&wrbtVersion=Y

Credentials

scheme://host/?type=credentials&interface=udp&link=overlay&pk=wrbtPk&message=encodedMessage&cjdnsVersion=X&wrbtVersion=Y

This text should be sent through one of the following methods.

All of them are easy to do, except QR code requires more work. Probably use zxing to encode and decode between text and QR.

Android implementation of wrbt to facilitate peering. It defines standardized peering requests and credential responses to be communicated via any channel (e.g. QR, NFC, email, text message, Twitter, etc.) that is recognizable across platforms (i.e. desktop vs. Android).

@benhylau mentioned on IRC the problem that to peer over Bluetooth, we'd have to pair the two devices, which IMO is an unnessecary complication.

So I'd like to propose either using Gilga or implementing a similar protocol to share creds over Bluetooth.

A Java implementation of yrd? Do you guys have something in mind?

Where can I find cjdroute-init? @benhylau

I'm following the instructions and ./android_do returns:
util/platform/netdev/NetPlatform_linux.c:37:30: fatal error: linux/ipv6_route.h: No such file or directory #include <linux/ipv6_route.h>

What's the status of this project? I'd love to see what can be done, help out, and possibly back this with $$$ if needed as well. We use cjdns where I work, and having access to stuff on Android would be cool.

It would help a lot if you could get the app on F-Droid (at f-droid.org).

Over Bluetooth, P2P WiFi, etc. Perhaps even Android Beam (Bluetooth transfer kickstarted via NFC).

Try this: https://github.com/servalproject/batphone/blob/0.93-pre/src/org/servalproject/ServalBatPhoneApplication.java#L653

API 23 does not allow TEXTREL:

W/System.err: CANNOT LINK EXECUTABLE "/data/user/0/berlin.meshnet.cjdns/files/cjdroute": /data/data/berlin.meshnet.cjdns/files/cjdroute: has text relocationsCANNOT LINK EXECUTABLE "/data/user/0/berlin.meshnet.cjdns/files/cjdroute": /data/data/berlin.meshnet.cjdns/files/cjdroute: has text relocationsAborted

See https://github.com/cjdelisle/cjdns/tree/master/tunnel and https://pad.meshwith.me/p/iptunnel

I am not sure what exactly needs to be done to make this happen. But the goal is to reach a Hyperboria-only site from the default browser.

@lgierth @kpcyrd I imagine we'd first need peering creds in cjdroute.conf or some kind of peers.d. Then we can get cjdroute running in the background. The we need to set up a VpnService, right?

On the Me page, we want to show a node graph to represent the all the direct connections to your phone. It gives an idea of how well-connect you are to the mesh network at the moment. Some relevant information may include:

• Last four bytes of your peer's address as in fc00.org
• The peering protocol expressed in colour code (e.g. IPTunnel, BT)

I am thinking a WebView loading a local JS implementation like this will do. See discussion on this topic here #16.

The tun interface never comes online on Oreo (Google Pixel)

This is possibly due to the app not getting certain permissions
