Initial set-up
user@mypc:~$ ssh [email protected]
The authenticity of host '192.168.0.1 (192.168.0.1)' can't
be established.
RSA key fingerprint is
62:a6:70:29:d4:1a:db:5a:75:6e:96:13:54:f5:a9:d9.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.0.1' (RSA) to the list
of known hosts.
[email protected]'s password:
eam999 ~ #
You will be prompted for a password; the default password is rootme. Note
that no characters will be echoed to the screen as you type the password.
Once connected, you will be presented with a shell prompt which is ready to
accept commands.
When you are finished with your SSH session and want to disconnect, enter
exit at the command line, or type
+
. There are a number of escape
sequences for controlling the session, all of which begin with a tilde ('~') so, if
you need to send a tilde character to the acquisition module, type two tildes
consecutively. For more information, see the section on “Escape Characters”
in the manual at
Note: If you plan to use ssh regularly to communicate with a
acquisition module, you can configure the system to bypass the
password prompt when logging in from a list of pre-authorised
computer/user combinations. This involves generating a unique
key-pair (for the user and PC which will access the acquisition
module) and then copying the public half of the key-pair to the
acquisition module. This can be more secure than passwords and is
fully documented at
For details
about uploading your keys to the CMG-EAM, see section 7.6 on
page 90.
