Title:
  Ubuntu 14.04 cannnot ssh into Chassis Manager

Status in The Lomond project:
  Confirmed

Bug description:
  REPRO STEPS:
  Trying to ssh into iloCM from an Ubuntu 14.04 terminal ssh client 
  (OpenSSH_6.6, OpenSSL 1.0.1f 6 Jan 2014). CM was running 1.20p20. 

  $ssh -vvv Administrator at CM-DEKE.americas.hpqcorp.net

  Connection fails with this message: 
  debug1: sending SSH2_MSG_KEXDH_INIT
  debug1: expecting SSH2_MSG_KEXDH_REPLY
  Received disconnect from 16.91.22.169: 3:  Key echange error

  
  SUMMARY:
  Ubuntu 14.04 (OpenSSH_6.6, OpenSSL 1.0.1f 6 Jan 2014) Works for other servers - not iloCM alone.

  Workaround:

  Goto /etc/ssh/ssh_config
  Uncomment the line:  Ciphers aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128,aes128-cbc,3des-cbc

  This seems to limit the number of ciphers in use.

  Also seems to be a known problem with "certain" configurations of
  openssh client and server. Please see URL:
