cssh opens extra windows about clusterssh HOT 3 CLOSED

Off the top of my head as I'm not near a computer ... you need to get the -p passed to ssh, not cssh. There is a cssh config option for that. You could also specify ports in your SSH config and then it's just automatic without need command line arguments.

from clusterssh.

Make use of built in ssh functionality by adding entries into your own user ssh config file - ~/.ssh/config. For example, for each server (as per your list above)

host 192.168.1.11 a1
  hostname 192.168.1.11
  user a1
  port 2022

host 192.168.12 a2
  hostname 192.168.12
  user a2
  port 2022

and then you can either use the IP address or the alias defined on the host line to open the terminals to each host using the config provided: cssh a1 a2

Look at man ssh_config for more details on all the options available
