• Status: Resolved
• Priority: Major
• Resolution: Fixed

• Component/s: auto-failover

Environment

If a site uses logjam protected ssh servers no common ciphers can be found and fencing breaks because the fencing process cannot be initiated by zkfc.

Description

Version 0.15.3 of jsch incorporates changes to add ciphers for logjam protection. See http://www.jcraft.com/jsch/ChangeLog.

Since there are no developer visible changes, updating pom is sufficient.

Doublechecked in my environment.
