Post your script source code and its output so we can see what you are doing at line 57, please!

Anyway, I guess your problem is that your host keys are not listed on ~/.ssh/known_hosts. You can add them as follows: 

my @hosts = qw(foo1.bar.com foo2.bar.com ...);

for (@hosts) {
  system "ssh $_ -o PreferredAuthentications=publickey -o StrictHostKe
+yChecking=no true"
}
