Accessing
via Ethernet
Interface
The E10 has a built-in Ethernet interface located on the wired side of the unit (refer back to
Figure 3-3 on page 22
for location). When a live network cable is plugged into this
interface, a green LED (built into the connector) lights up.
If the E10 detects any Ethernet traffic (even if it is addressed to a different device), a yellow
LED (on the same connector) begins to blink.
If you are not getting the expected indicator lights, troubleshoot your network cabling first
before trying to configure the E10.
Accessing the E10 via SSH
Determining IP Address
Once the E10 is successfully connected to the Ethernet, you may attempt to log in remotely.
To accomplish this, you need to know the E10’s IP address. This can be determined by first
logging into the E10 using the micro-USB serial port, and entering the
ifconfig eth0
command.
For example:
# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:1C:2C:FF:B5:EB
inet addr:192.168.1.82 Bcast:192.168.1.255
Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:507 errors:35 dropped:0 overruns:0 frame:0
TX packets:35 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:55342 (54.0 KiB) TX bytes:4644 (4.5 KiB)
Interrupt:21 Base address:0x4000
#
In the example above, the E10 has been assigned an IP address of
192.168.1.82
by the
local DHCP server. Your E10's actual IP address will likely be different.
Assigning an IP Address Manually
If your site does not utilize a DHCP server, you must tell your E10 what IP address to use.
Edit the file named
inittab
in the E10's
/etc
directory and add a line like the following,
putting it up near the top of the
inittab
file (and after the other, similar looking lines).
For example:
null::sysinit:/sbin/ifconfig eth0 192.168.1.82 netmask 255.255.255.0 up
Of course, you must replace the IP address shown above with your desired IP address. If
your network is not a Class C network, update the netmask as well.
Note:
Be sure to choose an IP address not already in use by some other device on your
network!
Reboot your E10 to allow the IP address change to take effect.
