why dont these ssh commands to shut down a computer work in a user script?

so i have 3 commands

server="192.168.0.4"
#ssh -o StrictHostKeyChecking=no -i /root/.ssh/id_rsa root@$server '/sbin/poweroff'
#ssh -o StrictHostKeyChecking=no root@$server '/sbin/poweroff'
ssh root@$server '/sbin/poweroff'

they both work fine in terminal mode.. but when i run it in a user script it will not shut down the computer.. and i use 192.168.0.4 in the terminal and it will shut down.. but in user script it does nothing how come?

as i have script it wakes up the computer rsyncs then shuts down... but it wont shut it down
