Ringserver setup query

[Steve Shuff]

Hi all,

I have just set up ew2ringserver and ringserver and could do with a little help with the configuration please.

The installation consists of a Raspberry pi3 with EW7.10 , when EW is started from the console all modules show as "Alive".

I have followed the installation guide by Chad at Iris but I must be missing something .

The ew2ringserver log is below

0240926_UTC_16:36:11 ew2ringserver(MOD_EW2RINGSERVER): Read command file <ew2ringserver.d>
 Version 2.2 2019-03-14
exportfilter_init: no wildcards in requested channel list;
                 will use binary search for SCNL matching.
exportfilter_init: configured to ship 1 channels:
    channel[0]:  WBK1 SHZ WF 00
exportfilter_init: Tracebuf packets will be exported regardless of latency.
                 To filter based on time, add MaxLatency to config file.

20240926_UTC_16:36:23 error: [192.168.0.5:18000] error setting socket to blocking

I can Telnet into the ringserver and send a "Hello" which returns the expected ringserver info.

The ring folder has been created and populated with "packetbuf " and "streamidx" files by EW.

Full paths have been set to the "ring" folder in the ringserver.d and also startstop_unix.d

Maybe someone can spot my error, Thanks for any help.

On ew2ringserver RSAddress should be ringserver RECEIVING port, so 16000 instead 18000.

Port 18000 is the ringserver port for incoming seedlink requests.

Try this way.

Steve,

Uncomment the last line in the ew2ringserver.txt file, syou are sending some data to the ringservrer.  Then use slinktool -Q Your_Host_Name:18000 to seed the seedlink streams, where Your_Host_Name is the host or IP address.

Hi Both, 

Thanks for the replies,

El Berto, I did as you suggested and also changed from the IP address to"Localhost" and I no longer get the errors, Thankyou.

Robert, Can I install Slinktool on a separate Raspberry Pi  on the same local network ?

My programming is not great but I can follow instructions.

So Far I  have installed Slinktool on another Pi and run "Make" with no errors, I am missing something though as it does not run ,

any guidance would be very appreciated ,

Thanks again

Steve,

Once you build the slinktool binary with the make command, run the slinktool prograrm:

   ./sllnktool -h

This assumes you are in the directory where the binary was built.  That should show how the command works.  Then try something like:

  ./slinktool -Q Host/IP:18000

where Host/IP is a hostname or IP address.  Once those test commands work, copy the binary to a directory on your path.  For example, /usr/local/bin:

  cp slinktool /usr/local/bin/

Then the program will run like any other command/program on your computer.

Thanks Bob,

So now I have 

pi@raspberrypi:~/Seismo/slinktool-main $ ./slinktool -Q 192.168.0.5:18000
WF WBK1  00 SHZ D 2024-09-27 16:24:21  -  2024-09-28 16:39:31
pi@raspberrypi:~/Seismo/slinktool-main $ 

 

looks like it's working , Thanks guys for all your help.
