Comment 19 for bug 556132

Tim pointed out that the ssh server has not yet been upgraded to the revision that fixes this.

I think I got a false pass because OpenSSH defaults to never initiating rekeying from the client. If I set 'RekeyLimit 50k' then it does hang, and presumably will eventually time out. On the other hand running the same command against qastaging, which does have this fix, succeeds.

So this should be fixed on the next major/with-downtime rollout of Launchpad, in a couple of weeks(?).
