The following is a set of instructions written by Julian Whitehead on how to get live data from his schools Guralp EDU seismomeetr onto the IRIS database in realtime (his school data can be accessed from IRIS under network code UK station STED) All this assumes they are running Windows XP and their Server is Windows Server 2003 (though I guess that most will be the same regardless of what you are running)! I think this was the sequence of steps that I took - maybe I should write this down properly if more schools are going to get this up and running! Step 1: In the Network control window in Scream, add the IRIS IP address and Port to push data to - 128.95.166.130:1567. It should also have UDP data selected and access to the data port enabled. Step 2: Contact Sandy ("Sandy Stromme" , )at IRIS, let them know that you are about to open up a port and transmit data to them. If you mention that we are about to start the same process that I did with STED, they will probably groan. Not sure if Sandy is a male or female Sandy. Step 3: Punch a hole in the school's firewall (normally the ISA server) that will allow transmission of data from the internal IP address of the Scream Machine (normally starting with 192.... but could be assigned differently), through to the IP address and port at IRIS (see above). The network manager will need to allow data to flow between the internal IP and the IRIS IP only - it should be UDP and maybe TCP. This should allow information to flow from the school to the SEGfL, but will be stopped by their firewall. Most of the above is relatively easy and can be accomplished in a matter of minutes. The hard part starts when dealing with SWGfL... Step 4: Contact SEGfL (arrggh). It might be worth having my project number so that SEGfL can speak to SWGfL - 242501. You need to ask SEGfL to open a port in their firewall that will allow data to flow from the school's hidden IP address to IRIS in Seattle. So in our case, we asked them to enable the following firewall rule. Ports 53764 and 1567 (the first was incase the second could not be picked up by IRIS and this is their port of choice). FROM: 10.3.160.xx (this is our private IP) with public facing IP: 62.171.219.xx To: 128.95.166.130 I also gave them the following information (there is a huge form to fill in): Access to: Incorporated Research institutions for seismology in Seattle, Wilbur 2 Data collection facility for seismic information collected locally in Poole. Port: 53764 or 1567 Protocol: tcp+udp Once this has all been carried out and IRIS have enabled their antelope server (with guralp2orb installed), there should another Guralp EDU instrument in the UK transmitting. The last process with SWGfL took us about 6 weeks, mainly because as fast as they were manually opening the hol in the firewall, the security software was closing it down! A small hack was needed apparently! Good luck, and please pass them my contact details as I am sure they will have questions, and I am quite happy to contact them directly. In the mean time I might put my mind to writing this all down...
