@ -3,11 +3,23 @@ have some way of pairing devices.
|

|
||||
It could work like this:
|
||||
|
||||
1. Prompt for the hostname (or do avahi local machine discovery).
|
||||
2. Enable the two hosts to ssh to one-another and run git-annex shell.
|
||||
(A tricky problem, if ssh keys need to be added to do that.)
|
||||
3. Push over a clone of the repository. (Using git-annex-shell?)
|
||||
4. Start [[syncing]].
|
||||
1. Prompt for the hostname, or do avahi local machine discovery, or use
|
||||
ZeroMQ with IP multicast, or use haskell's `network-multicast`. That
|
||||
last option seems to work best!
|
||||
2. Let user pick host to pair with. Somehow authenticate that this is
|
||||
the host they expected to pair with, and not an imposter. Probably
|
||||
have the users enter a shared secret and use it to HMAC the ssh public
|
||||
keys.
|
||||
3. Exchange a hostname or IP address with the pair. Ideally,
|
||||
use `.local`, as it'll work as long as both are on the same subnet.
|
||||
If mDNS is not available, regular DNS or IP addresses might have
|
||||
to be used, but will result in a more fragile pairing. Or perhaps
|
||||
the assistant could broadcast itself queries for current IP addresses,
|
||||
if connecting to a paired host fails.
|
||||
4. Enable the two hosts to ssh to one-another and run git-annex shell.
|
||||
(Set up per-host ssh keys.)
|
||||
5. Pull over a clone of the repository.
|
||||
6. Start [[syncing]].
