One way would be to make it very similar to +`git-annex-shell`, using rsync etc, and possibly reusing code from +git-annex-shell. However, it can take a while to make a connection across +the tor network, and that method seems to need a new connection for each +file transfered etc. Also thought about using a http based protocol. The +servant library is great for that, you get both http client and server +implementations almost for free.

Now git-annex is running as a Tor hidden service, but +it will only talk to peers after pairing with them. + +In both repositories, run this command: + + git annex p2p --pair + +This will print out a pairing code, like "11-incredible-tumeric", +and prompt for you to enter the other repository's pairing code. + +Once the pairing codes are exchanged, the two repositories will be securely +connected to one-another via Tor. Each will have a git remote, with a name +like "peer1", which connects to the other repository. + +Then, you can run commands like `git annex sync peer1 --content` to sync +with the paired repository. + +Pairing connects just two repositories, but you can repeat the process to +pair with as many other repositories as you like, in order to build up +larger networks of repositories. + +## how to exchange pairing codes + +When pairing with a friend's repository, you have to exchange +pairing codes. How to do this securely? + +The pairing codes can only be used once, so it's ok to exchange them in +a way that someone else can access later. However, if someone can overhear +your exchange of codes in real time, they could trick you into pairing +with them. + +Here are some suggestions for how to exchange the codes, +with the most secure ways first: + +* In person. +* In an encrypted message (gpg signed email, Off The Record (OTR) + conversation, etc). +* By a voice phone call. + +## starting git-annex remotedaemon on boot + +Notice the `git annex remotedaemon` being run in the above examples. +That command runs the Tor hidden service so that other peers +can connect to your repository over Tor. + +So, you may want to arrange for the remotedaemon to be started on boot. +You can do that with a simple cron job: + + @reboot cd ~/myannexrepo && git annex remotedaemon + +If you use the git-annex assistant, and have it auto-starting on boot, it +will take care of starting the remotedaemon for you. + +## speed of large transfers + +Tor prioritizes security over speed, and the Tor network only has so much +bandwidth to go around. So, distributing large quantities (gigabytes) +of data over Tor may be slow, and should probably be avoided. + +One way to avoid sending much data over tor is to set up an encrypted +[[special_remote|special_remotes]] someplace. git-annex knows that Tor is +rather expensive to use, so if a file is available on a special remote as +well as over Tor, it will download it from the special remote. + +You can contribute to the Tor network by +[running a Tor relay or bridge](https://www.torproject.org/getinvolved/relays.html.en). + +## onion addresses and authentication + +You don't need to know about this, but it might be helpful to understand +how it works. + +git-annex's Tor support uses onion address as the address of a git remote. +You can `git pull`, push, etc with those onion addresses: + + git pull tor-annnex::eeaytkuhaupbarfi.onion:4412 + git remote add peer1 tor-annnex::eeaytkuhaupbarfi.onion:4412 + +Onion addresses are semi-public. When you add a remote, they appear in your +`.git/config` file. For security, there's a second level of authentication +that git-annex uses to make sure that only people you want to can access +your repository over Tor. That takes the form of a long string of numbers +and letters, like "7f53c5b65b8957ef626fd461ceaae8056e3dbc459ae715e4". + +The addresses generated by `git annex peer --gen-addresses` +combine the onion address with the authentication data. + +When you run `git annex peer --link`, it sets up a git remote using +the onion address, and it stashes the authentication data away in a file in +`.git/annex/creds/` + +When you pair repositories, these addresses are exchanged using +[Magic Wormhole](https://github.com/warner/magic-wormhole). + +## security + +Tor hidden services can be quite secure. But this doesn't mean that using +git-annex over Tor is automatically perfectly secure. Here are some things +to consider: + +* Anyone who learns the address of a peer can connect to that peer, + download the whole history of the git repository, and any available + annexed files. They can also upload new files to the peer, and even + remove annexed files from the peer. So consider ways that the address + of a peer might be exposed. + +* While Tor can be used to anonymize who you are, git defaults to including + your name and email address in git commit messages. So if you want an + anonymous git-annex repository, you'll need to configure git not to do + that. + +* Using Tor prevents listeners from decrypting your traffic. But, they'll + probably still know you're using Tor. Also, by traffic analysis, + they may be able to guess if you're using git-annex over tor, and even + make guesses about the sizes and types of files that you're exchanging + with peers. + +* There have been past attacks on the Tor network that have exposed + who was running Tor hidden services. + <https://blog.torproject.org/blog/tor-security-advisory-relay-early-traffic-confirmation-attack> + +* An attacker who can connect to the git-annex Tor hidden service, even + without authenticating, can try to perform denial of service attacks. + +* Magic wormhole is pretty secure, but the code phrase could be guessed + (unlikely) or intercepted. An attacker gets just one chance to try to enter + the correct code phrase, before pairing finishes. If the attacker + successfully guesses/intercepts both code phrases, they can MITM the + pairing process. + + If you don't want to use magic wormhole, you can instead manually generate + addresses with `git annex p2p --gen-addresses` and send them over an + authenticated, encrypted channel (such as OTR) to a friend to add with + `git annex p2p --link`. This may be more secure, if you get it right. diff --git a/doc/tips/using_Google_Cloud_Storage/comment_8_1b4eb7e0f44865cd5ff0f8ef507d99c1._comment b/doc/tips/using_Google_Cloud_Storage/comment_8_1b4eb7e0f44865cd5ff0f8ef507d99c1._comment new file mode 100644 index 000000000..1a71f7726 --- /dev/null +++ b/doc/tips/using_Google_Cloud_Storage/comment_8_1b4eb7e0f44865cd5ff0f8ef507d99c1._comment @@ -0,0 +1,9 @@ +[[!comment format=mdwn + username="scottgorlin@a32946b2aad278883c1690a0753241583a9855b9" + nickname="scottgorlin" + avatar="http://cdn.libravatar.org/avatar/2dd1fc8add62bbf4ffefac081b322563" + subject="Coldline" + date="2016-11-21T00:49:23Z" + content=""" +Wanted to add that \"storageclass=COLDLINE\" appears to work seamlessly, both from my mac and arm NAS.

I will begin at the automatic +end, hoping that this is most useful, and drill down to the low level +approaches. Note, however, that this is the opposite order of how git-annex +was developed. A list of workflows that started from manual, +commandline usage would be much more intuitive, but you'd have to be +willing to read the man page and wiki pages to get started, and that's +pretty much what's already out there anyway. + +Note that for each of these levels of interaction, all the levels following +will also work as well. So you can actually manually move annexed files +around while the webapp is running, etc. + +# 1. [[git annex webapp|git-annex-webapp]] + +The [[`git annex webapp`|git-annex-webapp]] command launches a local web +server which serves a graphical user interface and automatically manages +git annex. It will attempt to guide you through the whole process and do +everything for you. The intent is that no other commands are +needed. This should be run on every machine that may produce file changes. + +# 2.

To create a repository, +use `git init` and then [[`git annex init`|git-annex-init]], and then `git +remote add` it to any other repositories. If you want more than one annex, +you can add their paths to `~/.config/git-annex/autostart` if you would +like them to automatically begin syncing when `git annex assistant +--autostart` is run, perhaps on boot or login. You can configure rules for +where files are copied using the repository setup commands such as [[git +annex preferred-content|git-annex-preferred-content]] to configure +[[content preferences|preferred content]] for what goes where, [[`git annex +numcopies`|git-annex-numcopies]] for how many [[copies]] must be kept of +each file, and [[`git config annex.largefiles`|tips/largefiles]] to define +small files that should be stored straight in git; most of the settings are +accessible in one place with [[`git annex vicfg`|git-annex-vicfg]]. + +# 3. [[git annex watch|git-annex-watch]] without the assistant + +The [[`git annex watch`|git-annex-watch]] command is like the assistant but +has no automatic network behavior, giving you complete control over when +repositories are pushed and pulled, and when files are moved between +systems. The local repository is watched, and any file changes are added to +git-annex. In order to synchronize between repositories, you must run +[[`git annex sync --content`|git-annex-sync]] in the repository with the +changes, which will merge the git history and logs with your remotes, and +automatically transfer files to match your preferred and required content +expressions. + +# 4. No background processes + +This allows you to decide when and what files are annexed. In order to tell +git-annex to manage files, you must [[`git annex add`|git-annex-add]] the +files. + +# 5. Plain [[git annex sync|git-annex-sync]] without `--content` + +This gives you fine-grained control of where copies of your files are +stored. [[`git annex sync`|git-annex-sync]] without `--content` tells +git-annex to merge git histories, but it does not automatically transfer +your large files between systems. To transfer files and directories, you +can use [[`git annex get`|git-annex-get]], [[`git annex +drop`|git-annex-drop]], [[`git annex move`|git-annex-move]], and [[`git +annex copy`|git-annex-copy]]. Git-annex will not violate a required content +expression or your numcopies setting unless you pass `--force`, so your +files are still safe. + +# 6.
