[f-nsp] Netiron 5.6 feedbacks

[Mitchell Warden]

Also seen in 5.7 and most likely in 5.7a. I think this happens after about 70 SSH logins.

I've been through the TAC and told it will be fixed in the next patch release for 5.6 and 5.7.

Zeroing out the key and recreating seems to work sometimes and/or briefly. Telnet is unaffected if you can get to the serial console to enable it :)

In other news, I just had ssh stop working on 5 MLX routers, all running
  5.6d:
  
  $ ssh myrouter
  invalid public DH value (1/1024)
  Disconnecting: bad server public DH value
  $ 
  
  When will Brocade get their act together on their SSH implementation?
  Does this really have to happen on every third firmware release?

  It is much easier to suggest solutions when you know nothing about the problem.
