# Standard filehandles
$remote->open(FILE, ">>X.X.X.X:/root/temp.txt") or die $!;
print FILE "Here's a line that's added.\n";
$remote->close(FILE);

i get the below error when executed.

Bareword "FILE" not allowed while "strict subs" in use at /root/Desktop/test.pl line 10.
Bareword "FILE" not allowed while "strict subs" in use at /root/Desktop/test.pl line 12.

Answer 1

You must install sh open keys to be able to access X.X.X.X without a password.

$ ssh-keygen
$ ssh-copy-id -i ~/.ssh/id_rsa.pub X.X.X.X

Than you can try to access the host with ssh:

$ ssh X.X.X.X 

And add please something like

local *FILE;

at the beginning of the file to get rid of these warnings about bareword.
