Re: telnetty/phpy/unixy thing

I don't remember the exact terms, but telnet won't work unless it's connected to a tty (ie, you're running it from a command prompt). That's why it works when you run it with the PHP binary. If you're intent on using this method, there's a couple of programs to look at: socket, and netcat. Although I'd just do this in PHP itself using the fsockopen() function (see the man page for an example). On Tue, 24 Jul 2001, Ben Bleything wrote: > Hey all...
