in thread IO::Pty, Net::Telnet and SSH [SOLVED]

Not a bad suggestion, but that defeats the purpose of this script I'm writing. I need to run an interactive program not on 1 server, on 500+ of them, so the idea is that this Perl script can connect to each server, and enter the same input that I gave the Perl script.

To give you an idea how this all fits together, when I run my script, it asks me for a list of servers, then it asks me a few questions. Once I'm done entering the info, the script will (when I find a fix for this IO::Pty, Net::Telnet and SSH issue) connect to each server and run the interactive program with the input I gave the program. So running the $ssh->shell isn't going to work.

    Hi,

    Don't know if this will work for you, but I know people who solved this kind of issue writting small servers that provide system commands with RPC capabilities, using SOAP or XML-RPC for example.

    I mean first try with what you are doing, if it works okay, but otherwise think about this:

      Caller.pl  <----XMLRPC/SOAP-----> Bridge.pl 
                                       /
                                       |
                                       /
      System/Native Program  <-----> Expect

    This way you can easily provide remote calls to existing programs that uses the STDIN without changing anything.

      Hi,

      While it is a good suggestion, it would be practically *impossible* to have this sort of thing approved in the company I work for. The idea is not to have to install a new daemon on each of the servers I manage, I'd like to work with what's already there (ie. SSH/Telnet).

      Besides, not all servers have expect.

      I'd love to have a look at the ssh_config of the person who got this Net::Telnet example working (was that you?). I can't think of what else it might be. Also, the OpenSSH version might be useful too, just incase it's a version thing.

      Thanks!
