running command on remote host by ssh fails when running inside script

Question

The Situation:
My Computer runs on Kubuntu 14.04. I am Admin of a Students House with some Netgear-APs. The idea is to have a script rebooting them all by one script. (ssh-key isn't posible)

The Problem in short:
ssh command on host runs fine from shell. But not if run by a script.

Description:
I have a Script on my Computer: "path/to/localScript"

#!/bin/bash

echo "Hello mister"
reboot

now if I enter the following directly in my shell

    sshpass -p '[MYPASSWORD]' ssh [USER]@[HOST] < PATH/TO/LOCALSCRIPT

I get the output

Pseudo-terminal will not be allocated because stdin is not a terminal.
Hello mister
Connection to HOST closed by remote host.

and the AP actually reboots! I tried other commands(like ping) -> all worked fine. Now I want to do exactly the same thing but inside a script (so I can later add all the other APs too ;) ) So I tried a script "rebootThemAll"

#!/bin/bash

echo " Rebooting AP 1"
sshpass -p '[MYPASSWORD]' ssh [USER]@[HOST] < PATH/TO/LOCALSCRIPT

I get the output

 Rebooting AP1 
Pseudo-terminal will not be allocated because stdin is not a terminal.

and ... nothing more happens. Again I see my input prompt on the shell line so the script stops. I also tried more than 1 AP to see if that error cancels my script but it didn't. For more APs the output look like this

 Rebooting AP1
Pseudo-terminal will not be allocated because stdin is not a terminal.
 Rebooting AP2
Pseudo-terminal will not be allocated because stdin is not a terminal.
 Rebooting AP3
Pseudo-terminal will not be allocated because stdin is not a terminal.
 Rebooting AP4
......

but the script won't run. It doesn't show the "Hello mister" and they are not rebooting..

Any one has an idea?

Solution 1

I could solve this problem using -T option "Disable pseudo-terminal allocation." and by using the scriptfiles without the #!/bin/bash line so just started with

echo "check" 
reboot

Solution 2

Try this:

sshpass -p '[MYPASSWORD]' ssh [USER]@[HOST] 'bash -s' < PATH/TO/LOCALSCRIPT

It seems that command is needed in the case when there is no terminal at all.
