Question

I am trying to avoid using Net::SSH::Perl library since there is some problems in installing the module using CPAN. Manual install seems too troublesome when I see that it depends on a long list of other Perl modules.

What I am trying to achieve is to log into the SSH with my username and password. Then I will need to run some commands in it and retrieve some files from the server using SSH.

I know how to pass the username, hostname and command using “ssh($username.”@”.$ip, $command) or die “SSH fails!”;”. However, I keep getting this error message:

ssh: connect to host XX.XX.XX.XXX port 22: Connection refused

where XX.XX.XX.XXX is the hostname or IP address of my computer and is in the subnet as the server that I am trying to get files from.

Does anyone knows how I can pass in the password to SSH or introduce me to good tutorials on Net::SSH? Most of the tutorials I found online are on Net::SSH::Perl and not for Net::SSH.

Answer 1

Did you see this FAQ section of the Net::SSH documentation?

Q: How do you supply a password to connect with ssh within a perl
script using the Net::SSH module?

A: You don’t (at least not with this module). Use RSA or DSA keys. See
the quick help in the next section and the ssh-keygen(1) manpage.

A #2: See Net::SSH::Expect instead.

The suggestion to try Net::SSH::Expect is a good one. It sounds, based on what you’ve said, that it fits your needs.
I have used Net::SSH::Expect quite a bit and I can attest to its simplicity if you’re just looking to get something done quickly
