Hi *,
I have just started to learn python and I am having a problem with
an python client connecting to a perl server using ssl (I tried this
with pyOpenSSL and with the build in SSL Module).
I don't want to check a cerificate, so i simply tried a
from OpenSSL import SSL
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(("127.0.0.1", 2000)
s.sendall("100 Hello\n")
ctx = SSL.Context(SSL.SSLv23_METHOD)
ctx.set_verify(SSL_VERIFY_NONE,self.verify_cb)
ss = SSL.Connection(ctx,s)
ss.set_connect_state()
ss.sendall("101 User\n")
when writeing the 101 I'll get an SSL23_GET_SERVER_HELLO
unknown protocol error. If I don't do the ssl stuff, everything
works.
I also tried this with the socket.ssl(s,None, None) to get a secure
socket - but I got the same error.
The server is not written by me - so I can't change that to python.
The problem is, that there is first an unencrypted socket, that is
converted to a secure socket.
the perl (server) code is something like this:
# creating a socket
$socket = IO::Socket::INET->new(Listen => 5,
LocalPort => 2000,
Timeout => 15,
Resue => 1,
Proto => 'tcp');
# some more code
# accepting a remote connection
$session = $socket->accept;
# some more code
# convert the Socket to an ssl socket
$sslsocket = IO::Socket::SSL::socket_to_SSL($session,
SSL_verify_mode => 0x00)
# some more code
Does anybody know, where the UNKNOWN PROTOCOL error
comes from? I have changed the connection Mode to
SSLv2_METHOD but this gave me an GET_SERVER_HELLO
read wrong packet type error.
I have done this with python 2.3.4 under linux - and the perl stuff
is done via the IO-Socket-SSL package.
Thx,
Chris
