Getting started
255.255.255.0 (24 bits of network address). A PC connected to this network
could communicate with the acquisition module if it was configured to use an IP
address of (for example) 192.168.0.2 with a matching netmask of
255.255.255.0.
Note:
IP addresses assigned using this method will be lost if the unit
is rebooted. To permanently assign an IP address, use the
net-setup
command or refer to the Platinum manual, MAN-EAM-0003, available
from www.guralp.com.
If you wish to connect to the NAM from a PC, they must either both be on the
same subnet (usually the first three numbers of the IP address) or be able to
connect to each other via routers.
In the latter case, you will need to tell the acquisition module the address of its
default router. Please refer to the Platinum manual, MAN-EAM-0003, for more
details.
4.3.4 Discovering dynamically allocated addresses
There are three ways to discover a dynamically allocated address. You can read
it from the unit's LCD display, you can query it from the command line or you
can use a broadcast address in Scream.
4.3.4.1 Using the command line
To use the command line, log in via the Platinum console or an SSH connection
and issue the command:
ip addr show dev eth0
You will see output like
nam999 ~ #
ip addr show dev eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc
pfifo_fast qlen 1000
link/ether 00:50:c2:40:54:75 brd ff:ff:ff:ff:ff:ff
inet 192.168.0.101/24 brd 192.168.1.255 scope global eth0
inet6 fe80:250:c2ff:fe40:5475/64 scope link
valid_lft forever preferred_lft forever
nam999 ~ #
The first line of the output should contain the word
UP
, confirming that the
adaptor has been enabled. The IP address that has been assigned is shown on
the line beginning
inet
- in this case, it is
192.168.0.101
(with a netmask of
24-bits indicated by
/24
).
Substitute
eth1
in place of
eth0
to see the address of the second port.
