i telnet in to multiple device and pipng it so after telnet i cannot spawn a ping sesssion so i need to use a send command but its not working ..any help pls


1. You say "it's not working".  Can you tell us what actually happens  as that will give a further clue as to what is going wrong.

2. You mention telnet, but I don't see any spawn of a telnet - perhaps the program you've posted is incomplete?   If you could come up with a short, complete example showing what's going wrong we might be able to help you a little better.

Use spawn to start a process, then send and expect to communicate with it; if you don't start off with a spawn, you can't send or expect.
