Hi All I have a system that has a standard telnet username password prompt to get access. Lets call this system X.
I also have a bit of software that can telnet to a port and performs a logging function. ( Records everything typed and printed on the console ). It also has a set of pattern based rules that can fire certain actions when certain stings are seen from system X.
The only problem with this piece of software is that it DOES NOT handle username and password prompts. Now - i hear you cry - thats rubbish. Yes is it but i've got to use it.
The idea : I create a process that sits between system X and the console. The process acts as both a telnet server and client. The client side performs a telnet onto the console using net::telnet which can handle the username password problem very nicely. The server side of the process creates a listen port using IO::socket into which the logging software can connect without a username password.
lines typed by the user from the logging software that arrive on the io::socket will simply be forwarded to the net::telnet connection. anything being printed on the console arriving from the net::telnet port will be forward back through the io::socket.
One slight complication is that events can occur on system X even if the user has not typed anything.
Has anyone written anything like this ?
