Answer 1

The third element in ssh_command is an integer. It needs to be a string.

e.g:

ssh_command = ["ssh", "-p", 29418, ...
#                            ^ problem

And the solution is simple, just add some quotes:

ssh_command = ["ssh", "-p", "29418", ...
#                           ^Now it's a string.
