in reply to Alarm and Telnet issues

Hi pubscout,

Your code probably is not working because Net::Telnet uses internly alarm and $SIG{ALRM} to handler timeouts itself.

You should use the Net::Telnet timeout instead.

    Bummer. I guess that means that there is no trivial way to have a global timeout when using Net::Telnet.

    Thanks for the help!

      Well, no lightweight trivial way. 
      use POSIX ();
$SIG{USR1} = sub { ... };
unless(fork) {
    sleep(4);
    kill(POSIX::SIGUSR1(), getppid());
    exit;
}
