Re: Making a shell work like a Net::Telnet session

in reply to Making a shell work like a Net::Telnet session

I must be missing something here. It sounds like you used to have: 
script-on-box --telnet--> hardware.

[download]
And now the hardware doesn't accept telnet connections, and you've got your script-on-box that doesn't know how to do ssh. So you want to do: 
script-on-box --telnet--> another box --ssh--> hardware

[download]
Net::Telnet will allow you to connect to an ssh session, so you could just spawn an ssh connection to the piece of hardware, then attach that ssh connection to your Net::Telnet object. (Search for 'spawn' in the Net::Telnet perldoc for an example of this.) Your script would continue to behave as it has in the past, interacting with a Net::Telnet object that just happens to be speaking ssh.

But I assume you already know this, so what am I missing?

    Have you actually tried the spawn sample on a Windows box? I am almost sure it will not work.

    IO::Pty does not compile there, you could just use IPC::Open2 but Net::Telnet uses select to poll the connection and on Windows select does not work with pipes.

    Later versions of perl have a socketpair emulation that uses TCP internally (it goes through localhost) but the last time I tried it with OpenSSH, it didn't like having its stdio attached to a TCP socket.

      Aha! Okay - I missed that this was on a Windows box. Thanks for the clarification.
