# Installation
|
|
|
|
First, make sure that the latest [trezorlib](https://pypi.python.org/pypi/trezor) Python package
|
|
is installed correctly (at least v0.6.6):
|
|
|
|
$ apt-get install python-dev libusb-1.0-0-dev libudev-dev
|
|
$ pip install Cython trezor
|
|
|
|
Then, install the latest [trezor_agent](https://pypi.python.org/pypi/trezor_agent) package:
|
|
|
|
$ pip install trezor_agent
|
|
|
|
Finally, verify that you are running the latest [TREZOR firmware](https://mytrezor.com/data/firmware/releases.json) 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:
|
|
|
|
/tmp $ trezor-agent ssh.hostname.com -v > hostname.pub
|
|
2015-09-02 15:03:18,929 INFO getting "ssh://ssh.hostname.com" public key from Trezor...
|
|
2015-09-02 15:03:23,342 INFO disconnected from Trezor
|
|
/tmp $ cat hostname.pub
|
|
ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBGSevcDwmT+QaZPUEWUUjTeZRBICChxMKuJ7dRpBSF8+qt+8S1GBK5Zj8Xicc8SHG/SE/EXKUL2UU3kcUzE7ADQ= ssh://ssh.hostname.com
|
|
|
|
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.
|
|
|
