Sdt Connector Public Key Authentication - Tripp Lite B092-016 Owner's Manual

Chapter 15: Advanced Configuration
Authorized Keys:
If the Console Server selected to be the server will only have one client device, then the authorized_keys file is simply a copy
of the public key for that device. If one or more devices will be clients of the server, then the authorized_keys file will contain a
copy of all of the public keys. RSA and DSA keys may be freely mixed in the authorized_keys file.
For example, assume we already have one server, called bridge_server, and two sets of keys, for the control_room and the
plant_entrance:
$ ls /home/user/keys
control_room control_room.pub plant_entrance plant_entrance.pub
$ cat /home/user/keys/control_room.pub
/home/user/keys/plant_entrance.pub >
/home/user/keys/authorized_keys_bridge_server
Uploading Keys:
The keys for the server can be uploaded through the web interface, on the System: Administration page as detailed earlier.
If only one client will be connecting, then simply upload the appropriate public key as the authorized keys file. Otherwise,
upload the authorized keys file constructed in the previous step.
Each client will then need its own set of keys uploaded through the same page. Take care to ensure that the correct type of
keys (DSA or RSA) go in the correct spots, and that the public and private keys are in the correct spot.

15.6.8 SDT Connector Public Key Authentication

SDT Connector can authenticate against a Console Server using your SSH key pair rather than requiring your to enter your
password (i.e. public key authentication).
• To use public key authentication with SDT Connector, first you must first create an RSA or DSA key pair (using ssh-keygen,
PuTTYgen or a similar tool) and add the public part of your SSH key pair to the Console Server – as described in the earlier
section.
• Next, add the private part of your SSH key pair (this file is typically named id_rsa or id_dsa) to SDT Connector client. Click
Edit: Preferences: Private Keys: Add, locate the private key file and click OK. You do not have to add the public part of
your SSH key pair, it is calculated using the private key.
SDT Connector will now use public key authentication when SSH connecting through the Console Server. You may have to
restart SDT Connector to shut down any existing tunnels that were established using password authentication.
If you have a host behind the Console Server that you connect to by clicking the SSH button in SDT Connector, you can also
configure it for public key authentication. Essentially what you are using is SSH over SSH, and the two SSH connections
are entirely separate, and the host configuration is entirely independent of SDT Connector and the Console Server. You
must configure the SSH client that SDT Connector launches (e.g. Putty, OpenSSH) and the host's SSH server for public key
authentication.
