I suspect the error comes from IO::Pty when it attempts to allocate a pseudo terminal. The '-t' option will force allocation of a pseudo terminal, but this may not make any difference for you as your application appears to already be attempting to do so, and failing.

Net::OpenSSH uses IO::Pty to allocate a pseudo terminal and this, in turn, uses IO::Tty. The latter is documented to be system dependent. You might check the IO::Tty documentation to ensure the system you are on is listed as known working. In particular, if you are on Windows it says you must be using Cygwin. On the other hand, it says the list is out of date.

A pseudo terminal will be allocated if you are using password authentication. If you are using password authentication, even if you can get pseudo terminals to work, you might be better off to heed the warning in the Net::OpenSSH documentation:

Note that using password authentication in automated scripts is a very bad idea. When possible, you should use public key authentication instead.

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
