15. Advanced Conﬁguration

If the Tripp Lite device selected to be the server will have only one client device, 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, the authorized_keys ﬁle will contain a copy

of all 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

15.6.5 Generating Public/Private Keys for SSH (Windows)

This section describes how to generate and conﬁgure SSH keys using Windows.

First, create a new user from the Tripp Lite management (the following example uses a user called “testuser”), making sure it

is a member of the “users” group.

If you do not already have a public/private key pair, you can generate them now using ssh-keygen, PuTTYgen or a similar tool:

PuTTYgen: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

OpenSSH: http://www.openssh.org/

OpenSSH (Windows): http://sshwindows.sourceforge.net/download/

For example, when using PuTTYgen, make sure you have a recent version of the puttygen.exe (available from http://www.

chiark.greenend.org.uk/~sgtatham/putty/download.html). Also, make sure you have a recent version of WinSCP (available

from http://winscp.net/eng/download.php ).

To generate a SSH key using PuTTY http://sourceforge.net/docs/F02/#clients:

• Execute the PUTTYGEN.EXE program.

• Select the desired key type SSH2 DSA (you may use RSA or DSA) within the Parameters section.

• It is important that you leave the passphrase ﬁeld blank.

• Click on the Generate button.
