Notes: Additional “urgent” releases may be scheduled for the 4th Tuesday of each month.

Discussions

Support Update

  • Hosted CE GSISSH meeting today; Suchandra, BrianL, and possibly Jaime Frey will attend
  • Suchandra had questions about running multiple CE services on a single host to limit IPv4 addresses. Will try IPv6 instead and coordinate with Edgar for Factory integration.

Support Update

  • MIT (BrianL) - Investigated open UDP ports for GridFTP: turned out to be an old version of GridFTP
  • UFL (BrianL) - Assisted Bockjoo with Slurm timeout issues
  • Purdue (Derek) - Assist in configuration of OSG_WN_TMP for their cluster.
  • ALICE (Derek) - Alice VO had issues with submitting usage to GRACC. So far, seems like it's the probe.
  • Fermilab (Suchandra) - disabling SSLv2/SSLv3 for BeStMan, BrianB to speak to them about transitioning them to another storage solution
