Hello everyone,

I know the seedlink module is relatively new, but I'm having trouble using it. I've tried running the tests manually, but this is what I get:

% python /path/to/obspy/seedlink/tests/test_slclient.py
SLClient comes with ABSOLUTELY NO WARRANTY
DEBUG: obspy.seedlink [geofon.gfz-potsdam.de:18000]:primary loop pass 0
ERROR: obspy.seedlink [geofon.gfz-potsdam.de:18000]:cannot connect to SeedLink server: [Errno 110] Connection timed out
DEBUG: obspy.seedlink [geofon.gfz-potsdam.de:18000]:primary loop pass 1
DEBUG: obspy.seedlink [geofon.gfz-potsdam.de:18000]:primary loop pass 2
...

DEBUG: obspy.seedlink [geofon.gfz-potsdam.de:18000]:primary loop pass 60
DEBUG: obspy.seedlink [geofon.gfz-potsdam.de:18000]:primary loop pass 61
ERROR: obspy.seedlink [geofon.gfz-potsdam.de:18000]:cannot connect to SeedLink server: [Errno 110] Connection timed out

...and this continues every 60 loops. I don't know what I'm supposed to see. Is it possible that my computer can't see out to the server? (googling Errno 110 was not very helpful.) I have an http proxy and can use obspy.iris, but I don't know if obspy.seedlink would use it.

Thanks in advance for any help,
Jon

Hi Jon:

That IP and Port combination are fine.

Try pinging 8.8.8.8 to see if you have internet.

Then try telnet-ing to that IP and port:
telnet geofon.gfz-potsdam.de 18000

It respond to me so you can use this to test your connection. (Note: that IP does NOT respond to ping; I am assuming you are using Linux here)

It is also possible that your system administrator has port 18000 blocked.

Kind Regards from Panama,

Hi all,

I have not used the seedlink client very much so far and can not comment
on the particular issue. But I think you might want to have a look at
the seedlink plotter started by Stephane and Lion some weeks ago:
https://github.com/bonaime/seedlink_plotter

It works pretty OK right now and if the examples run for you, you can
exclude any firewall issues, I guess. (Note that the current stable
obspy 0.8.3 is not recent enough)

hope it helps,
Tobias
