Named pipe and python command line

[pepsidrinker]

Hi everyone,
Im having a moslty 'common' issue I guess, but I cant seems to solve it.
It seems to be a problem where u have to know the solution, or you'll have to search like hell to find the solution.

Basically, I would like to use 'scapy' in a c++ program.
Scapy use the Python Prompt to process its stuff(just like a normal console prompt, taking command and printing stuff), so I need to be able to send command & receive the answer.
To do this, I assume a good way would be to use Linux Named Pipe (FIFO).
So I created my 2 pipes(one for stdout & the other one for stdin).
1rst pipe : pipe_input
2nd pipe : pipe_output
To test them, i use the following:
cat pipe_input | scapy > pipe_output

Im only able to send 1 command to scapy & receive 1 answer, cause then both end of the pipe ends (EOF received I guess?).


I there a way to tell the pipe to continue 'piping' until scappy exit?

try

cat pipe_input | scapy > pipe_output << "EOF"

just a guess

Tks for reply,

Tryed the code, didnt work.
The sign ">" apperas on each line, as if the console was waiting for something...

well, what happens when you use my code and input "EOF" and press enter? it should exit then
