## Installation
|
|
|
|
|
|
|
|
|
|
First, make sure that the latest `trezorlib` Python package
|
2015-09-06 08:50:45 +00:00
|
|
|
is installed correctly (at least v0.6.6):
|
2015-08-24 11:49:05 +00:00
|
|
|
|
|
|
|
|
$ pip install Cython trezor
|
|
|
|
|
|
2015-08-24 11:49:51 +00:00
|
|
|
Then, install the latest `trezor_agent` package:
|
2015-08-24 11:49:05 +00:00
|
|
|
|
|
|
|
|
$ pip install trezor_agent
|
|
|
|
|
|
2015-09-04 19:20:33 +00:00
|
|
|
Finally, verify that you are running the latest TREZOR firmware version (at least v1.3.4):
|
|
|
|
|
|
|
|
|
|
$ trezorctl get_features
|
|
|
|
|
vendor: "bitcointrezor.com"
|
|
|
|
|
major_version: 1
|
|
|
|
|
minor_version: 3
|
|
|
|
|
patch_version: 4
|
|
|
|
|
...

## Public key generation
|
|
|
|
|
|
|
|
|
|
Run:
|
|
|
|
|
|
2015-09-02 12:12:33 +00:00
|
|
|
/tmp $ trezor-agent ssh.hostname.com -v > hostname.pub

|
2015-08-24 11:49:05 +00:00
|
|
|
|
|
|
|
|
Append `hostname.pub` contents to `~/.ssh/authorized_keys`
|
|
|
|
|
configuration file at `ssh.hostname.com`, so the remote server
|
|
|
|
|
would allow you to login using the corresponding private key signature.
