Automatic command to Telnet
I'm trying to send a command automatically via Telnet, but without success.
I can do this:
Code:
> telnet 100.100.100.1 8080
Trying 100.100.100.1...
Connected to 100.100.100.1.
Escape character is '^]'.

Whereby I enter "command" and everything works like a charm, but I'd like to do this non-interactively, so I tried this:
Code:
echo command | telnet 100.100.100.1 8080

Doesn't work! What to do?

try:
Code:
(
sleep 1
echo username
sleep 1
echo passwd
sleep 1
echo "your-command"
) | telnet x.x.x.x

This will almost do the trick.
Code:
(
sleep 1
echo "hello"
) | telnet 100.100.100.1 8080

The problem is that sometimes the "hello" is outputted correctly and sometimes I get an empty string. I have no idea why.Smilie

This works perfectly.
Code:
echo "command" | netcat 100.100.100.1 8080

Unfortunately I don't have the luxury to assume that every system that needs this will have netcat. Still in trouble.
