Title:
  sFTP very slow to connect and causes Nautilus to randomly freeze

Status in “nautilus” package in Ubuntu:
  Confirmed

Bug description:
  Linux ubuntu 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
  Ubuntu 14.04

  Problems with Nautilus and smbd.

  Nautilus takes minutes to connect to sFTP servers and once connected,
  it randomly freezes (window turns dark and doesn't respond for 30-60
  seconds). This happens often, but not only, after a time of
  inactivity. Other software using sFTP, like text editors with sFTP
  support, are also affected.

  so I guess at least part of the problem are the frequent disconnects,
  which are not network related.  It's both a problem with smbd and
  Nautilus however, because Nautilus should handle the disconnects
  better and not freeze all the time.

  Connecting via SSH through CLI is instant and doesn't cause any
  problems whatsoever, so again, it's not a network problem.

  I have installed Ubuntu 14.04 on several machines and they all have
  the same problems. If the problems persist, I will have to look for an
  alternative, as it's impossible to work like this.
