Just a simple test:
wget http://rlsatlas.cern.ch:7777/
Works at CERN (of course), but not from IFIC (lcg2ui.ific.uv.es).
There is no firewall problems from our side. Checked running a tcp
server listening on port 7777 in a machine outside our network and
connecting with a client from lcg2ui.ific.uv.es.
Is there something in the CERN network or in rlsatlas.cern.ch that is
blocking traffic coming or going to our network (147.156.0.0/16) ?
Please, it is important because we have 84 ATLAS jobs on our site
failing or hanging one way or another doing lcg-xx commands and I
really think it is related to this problem.
Thanks for your help.
Regards,
Javier
