On a related note, from what I can tell the update to 1.8 has disabled some SSL connect methods. Sadly, this has locked me out of any Dell DRAC5 remote console interfaces... I'm hunting for a way to re-enable the disabled SSL methods, but I'm not quite sure how to do so... I'm on Fedora 21 on my desktop - but I believe its the same with any upgrade to 1.8 - even the Oracle JRE disables these SSL methods :( -- Steven Haigh Email: net...@crc.id.au Web: http://www.crc.id.au Phone: (03) 9001 6090 - 0412 935 897
