simple command line client

[Lucito07]

Hi,

I would like to know if any one knows of a simple command line client that can connect to a secure server using ssl, send a string of text, wait for a response and returns with that response. I know that with OpenSSL you can connect to the server using 'openssl s_client -connect remote.host:remote.port', but I would need to send the data and return with the response from a single command. Is that possible with OpenSSL directly, or is there a simple client that can do that?

Kindest regargs,

JLP

Stunnel.

It armours a basic connection into SSL, but you'd still need to run "expect" or "nc".

I made a some I/O routines of SSL to make it 'easier'
check this, maybe it can be useful for you.

Hm, this should be possible straight out of the box, by feeding the
input to s_client through redirection so you'd get an EOF on stdin in
there once the line is fetched. What I mean is this: run

  echo "line to be sent to server" | s_client -host example/com -port 443

and the server's response should appear on stdout, while the OpenSSL
s_client app will terminate once that initial line is sent and the
server has sent a response and closed the connection.
(s_client can also be compiled as a separate binary)

Haven't tested this recently but I seem to recall that worked for me once.

Just make sure your command doesn't start with a capital 'Q'. ;-)

Thank a lot for the feedback. I will give it a shot.

Thank a lot for the feedback. I will give it a shot. On what platform can it be compiled? Is the code portable as I might have to debug here at the office on Windows, and we might deploy later on a Linux platform?

Kindest regards,
