Cannot copy files from EOS

O²
1

Dear all,
I’m trying to copy files from EOS, but the process remains hanging.
For example:

XrdSecPROTOCOL=sss,unix XrdSecSSSKT=$HOME/.alimidvs.sss.keys xrdcp root://eosaliceo2.cern.ch//eos/aliceo2/ls2data/GC/ECS/2TSKnCAAkpJ_501296/o2_ctf_run00501296_orbit0004612092_tf0000018016.root ./

If I run in debug mode I get:

[2021-09-23 10:02:20.633276 +0200][Dump   ][TaskMgr           ] Running task: "TickGeneratorTask for: root://eosaliceo2.cern.ch:1094"

Notice that this is quite new: I used to copy files from EOS without problems. Not sure what changed.
Is there some issue on the EOS side?
Thanks in advance,
cheers,

Actually, I am able to copy this and other files on CERN GPN, but it indeed hangs when the copy is done from outside of CERN

Hi @shahoian ,
you’re right, I can copy files from lxplus…although it is quite cumbersome.
The strange thing is that I could copy files from outside CERN until few days ago, and I do not think I changed anything. So I guess something changed in our EOS.
Anyways, I’ll try to copy to lxplus and then copy from there…
Thanks,
cheers,
Diego

Answer from Latchezar:

The firewall to EOSALICEO2 is closed for the time being due to kernel vulnerability. This will persist until RedHat provides a solution for the problem, probably about a week.

Any news about when the reopening of the firewall will actually occur ?
Thanks
