Page 9: Getting Started
The Güralp Affinity can be configured and monitored either over an Ethernet network or via a serial (RS232) line. If using a network, the Affinity can be accessed using a web browser or, in character mode, using ssh. Instructions for connecting to the network port are given in section 4.2 on page 9. - Page 10 - Scream will then start monitoring DHCP traffic on the local network. Power up the Affinity and allow it a minute to boot. When Scream notices a DHCP negotiation with an appropriate MAC address, it will display the allocated IP address in the window.
- Page 11 Affinity Getting Started address is pre-configured when you first install Scream. To use this feature, right- click on the multicast address and select GCFSEND:B from the context menu: All accessible Affinities (and many other GCF servers) will respond and their IP addresses will be displayed in the right-hand "Control"...

Page 14: Link-Local Addresses
Affinity Getting Started Registry address - This field allows specification of an alternative registry • server, if desired. Güralp own and operate the server at 52.34.40.123, which is the default, and this server is available for public use. You may prefer to operate your own registry server if, for example, your telemetry network is not connected to the public Internet. -
Page 15: Assigning A Static Ip Address
Scream's Network Control window and add a UDP server using the link-local network's broadcast address, 169.254.255.255, and start communicating immediately. If the address of the Affinity is required (for, say, web access), this can be read from Scream's control window, or in the acknowledgement window resulting from a GCFPING. - Page 16 Affinity Getting Started The following screen is displayed: Using the keys (or, on some systems, depending on your terminal type, the mouse), select whether you wish to use DHCP or static addressing. The red letters in the display indicate short-cut keys so, for example, you can, key select DHCP or to select static addressing.
- Page 17 4.2.3.1 on page 15), the web interface or gconfig. Please see the Platinum manual for more details. If you wish to connect to the Affinity from a PC, they must either both be on the same physical network and have the same network address (usually the first three numbers of the IP address) or be able to connect to each other via routers.
-
Page 18: Connecting To The Web Interface
Affinity Getting Started In the latter case, you will need to tell the Affinity the address of its default router (also known as the gateway). Issue the command: G12345 ~ # ip route add default via 192.168.0.254 substituting the address of your network's default router in place of the example address (192.168.0.254) shown. -
Page 19: Connecting To The Command Line Using Ssh
If the browser fails to connect, the most likely explanation is that the machine running the browser does not have working network communications to and from the Affinity. This can be verified by “pinging” the IP address of the browser from the command line of the Affinity: G12345 ~ # ping -c3 192.168.0.2... - Page 20 “host key”. This is normal but, if you are ever asked this again, it means that either the host key of the Affinity has changed – perhaps because of a firmware upgrade – or there is a network address conflict or, worse, a security problem on your network.
- Page 21 “Start” menu or double-clicking on its icon. You will be presented with the following screen: Enter the IP address of the Affinity into the Host Name (or IP address) field, check that SSH is selected as the Connection type and then click the button.
- Page 22 PuTTY allows you to save multiple sessions, along with a default login identity and screen colours for each. See the PuTTY manual for more details. Note: If you plan to use ssh regularly to communicate with an Affinity, you can configure the system to bypass the password prompt when logging in from a list of pre-authorised computer/user combinations.
