Hi folks, I spoke to our security guy about this this afternoon when a couple of my staff who run Firefox, ran afoul of the issue. He recommended the same workaround but advised that this option will be removed in future versions of Firefox (and likely Chrome and Mozilla, also).
Cisco either need to release a patch to increase the Diffy-Hellman keysize for these servers or publish a hoot guide for us to do it ourselves. --- /-Gary Parker----------------------------------f--\ | Unified Communications Service Manager | n Loughborough University, IT Services | | tel:+441509635635 im:[email protected] o | http://delphium.lboro.ac.uk/pubkey.txt | \r----------------------------------------------d-/ > On 9 Jul 2015, at 21:07, Charles Goldsmith <[email protected]> wrote: > > Thanks Ryan and Dennis, that did the trick! > > On Thu, Jul 9, 2015 at 1:55 PM, Heim, Dennis <[email protected]> wrote: > <image005.png> > > > > Dennis Heim | Emerging Technology Architect (Collaboration) > > World Wide Technology, Inc. | +1 314-212-1814 > > <image006.png> > > <image007.png><image008.png><image009.png> > > “There is a fine line between Wrong and Visionary.
