Page: 242 / 279

222 Options List
C.22.4 SSH Console Interface
These instructions cover the setup and maintenance of the 1088A/B using the Secure Shell (SSH)
Console Interface. Secure Shell is an alternative to using the Telnet protocol, and used for securely
gaining access to a remote system like the optional Option 34. Configure all settings through one
of the Ethernet ports. Instructions on using the Web Interface for the same purpose are found in
Section C.22.3.
Any Secure Shell (SSH) client, like OpenSSH or PuTTY
TM
, is suggested. Make sure to select
SSH and type in the device’s IP address and connect. For Mac users, Terminal works fine. At the
command prompt (
B is the command prompt) type: B
ssh clockoption@ host
where
host
is
either the hostname (if served by your DNS server) or the IP address.
Press ENTER after typing the IP address. Shortly, you should be prompted for the password.
Type in the password and press ENTER. The console interface should open and appear similar to
Figure C.49.
Startup Page: System Status
When logging in to the Option 34 using SSH console the opening screen should be the System
Status information page. This provides an overview of the operation of the Option 34. Figure C.49
illustrates the opening page.

If you do not know the IP address of the port you are connected to, press the SYSTEM key
on the front panel several times until you reach
OPTION STATUS
and press the ENTER. Press the
UP or DOWN keys to scroll through the Option 34 pages. Messages should appear separately for
NET1 (port 1) and for NET2 (port 2). If the IP addresses do not appear, then check to make sure
a network cable is connected between the chosen port and an active network. If there is no DHCP
server on the network, a port set for DHCP will not display. Factory default settings include Port
1 set with a static IP address – 192.168.0.232. Make sure that the Link LED is lit.
IP addresses for all Ethernet ports of the installed Option 34 are either set automatically by the
Dynamic Host Configuration Protocol (DHCP) server on your network, or set to a static address.
The front panel will indicate the IP address of each port, if there is a connected cable.
