Dear All,
There are two points worth noting from today’s (delayed) WLCG ops meeting:
• RHEL/SL 6.9 openssl update fall-out
• openssl 1.0.1e-57 by default prohibits TLS to be used with DH keys smaller than 1024 bits
• Java-based services will fail openssl client connections if their version of Java is too old
• Or if its disabled algorithms are defined incorrectly
• Java-based services need to run a sufficiently recent version of Java to avoid such problems
• The latest 1.7 and 1.8 releases should be OK
• Last Thu an alert about this matter has been sent to the wlcg-operations list
• Networks:
• perfSONAR 4.0 was released on 17th of April (http://www.perfsonar.net/release-notes/version-4-0/)
• Site on auto-updates will get it automatically - no action needed.
• Sites planning to update perfSONARs to CC7 are encouraged to wait until 4.1 is released.
