Title:
  ssh long waiting time (delay) on 12.04  (not on 11.04)

Status in “openssh” package in Ubuntu:
  Expired

Bug description:
  We have two subnetworks (with static IP v4 addressing). Call it here
  subnetwork  S1  and subnetwork  S2 .

  There is a machine  P  on  S1 .  It is the local machine from which I
  am reporting this bug. It has a fresh clean installation of xubuntu
  12.04 (Precise), 32-bit version.

  There is a machine  M  on  S2 .  It runs ubuntu 10.10, 64-bit version
  (Maverick).

  ##################  the problem  ####################
  When I issue an ssh  (or scp or rsync) command on   P ,  aiming to access   M ,  I must wait rather long time, about 5 seconds, before I get the login prompt.
  ################################################

  There is also another machine, call it  N  (ubuntu 11.04) ,  on S1.  I.e. machines  P  and   N  are on the same subnetwork  S1.
  When I type  ssh on  N , again aiming to access  M , there is no such a delay (the login prompt is got immediatelly).

  The only essential difference (in my opinion) between machines  P  and  N  is in (x)ubuntu version (and also openssh versions).
  P  uses  xubuntu 12.04,  32-bit.  (Precise)
  N  uses  ubuntu 11.04, 64-bit.  (Natty)

  BTW, when logging from  P  to  N  (i.e. within the same subnetwork
  S1), there is no delay.

  In summary, while ubuntu 11.04 has no problem with ssh to the other
  subnetwork, xubuntu 12.04 causes the unpleasant delays.

  There is no nameserver issue. I am using /etc/hosts or ever manually
  typed IP adresses (numbers) when doing the ssh communications.
