The only downside is this:

  • you open a first connection
  • you open a second connection
  • you want to close the first connection
  • you can't, because the second connection is still up

@nixCraft oh, interesting I have a jump host and behind that hundred computers. And I need to run a command on each of them. Doing 100 ssh in parallel does not work, as several fail. I guess because out of connections on my laptop.
So this trick will be very useful.
Just need to check how many outgoing connections the jumphost can handle.
