Once this connection arrives, SSLTap makes another connection +to hostname:port (server side). It passes any data sent by the client to +the server, and vice versa. However, SSLTap will also display the data +to the console. It can do this for plain HTTP connections, or any TCP protocol. +However, SSLTap can also work with SSL streams, as detailed below. + +<P>Let's assume your development machine is called 'intercept'. The simplest +usage of SSLTap is to run the command <TT>'ssltap www.netscape.com:80'</TT> +on intercept. The program will wait for an incoming connection on port +1924. Next you would want to go to your browser, and enter the URL http://intercept:1924. +The page retrieved by the browser will actually be gotten from the server +at www.netscape.com, but will go via SSLTap. + +<P>Data sent from the client to the server is surrounded by a '--> [ ]' +symbol, and data sent from the server to the client, a '<---[ +]' symbol. + +<P>You'll notice that the page retrieved with this example looks incomplete. +This is because SSLTap by default closes down after the first connection +is complete, so the browser is not able to load images. To make the SSLTap +continue to accept connections, switch on looping mode with the -l option. + +<P>You can change the default rendezvous port to something else with the +-p option. + +<P>The remaining options change the way the output is produced. + +<P>The -f option prints 'fancy' output - in colored HTML. Data sent from +the client to the server is in blue. The server's reply is in red. This +is designed so you can load the output up into a browser. When used with +looping mode, the different connections are separated with horizontal lines. + +<P>-x will turn on HEX printing. Instead of being output as ascii, the +data is shown as Hex, like this: +<UL><TT><-- [</TT> +<BR><TT> 0: 56 d5 16 3e a1 6b b1 4a 8f 67 c4 d7 +21 2f 6f dd | V..>.k.J.g..!/o.</TT> +<BR><TT> 10: bb 22 c4 75 8c f4 ce 28 16 a6 20 aa +fb 9a 59 a1 | .".u...(.. ...Y.</TT> +<BR><TT> 20: 51 91 14 d2 fc 9f a7 ea 4d 9c f7 3a +9d 83 62 4a | Q.......M..:..bJ</TT> +<BR><TT>]</TT> +<BR> </UL> + +<H4> +SSL Parse mode</H4> +The following options deal with SSL connections. +<UL>-s will turn on SSL parsing. (SSLTap doesn't automatically detect SSL +sessions.) +<BR>-x will turn on extra SSL hexdumps. Mostly, if SSL can decode the data, +it doesn't display the hex.</UL> +The following SSL3 Data structures are parsed: Handshake, ClientHello, +ServerHello, CertificateChain, Certificate. In addition, SSL2 ClientHello, +ServerHello, ClientMasterKey are also partly parsed. NO DECRYPTION IS PERFORMED +ON THE DATA. SSLTAP CANNOT DECRYPT the data. + +<P>If a certificate chain is detected, DER-encoded certificates will be +saved into files in the current directory called 'cert.0x' where x is the +sequence number of the certificate. +<BR> +<H3> +Operation Hints</H3> +Often, you'll find that the server certificate does not get transferred, +or other parts of the handshake do not happen. This is because the browser +is taking advantage of session-id-reuse (using the handshake results from +a previous session). If you restart the browser, it'll clear the session +id cache. + +<P>If you run the ssltap on a different machine that the ssl server you're +trying to connect to, the browser will complain that the host name you're +trying to connect to is different to the certificate, but it will still +let you connect, after showing you a dialog. +<H3> +Bugs</H3> +Please contact <A HREF="mailto:ssltap-support@netscape.com">ssltap-support@netscape.com</A> +for bug reports. +<H3> +History</H3> +2.1 - First public release (March 1998) +<BR> +<H3> +Other</H3> +For reference, here is a table of some well-known port numbers: +<BR> +<TABLE BORDER=2 > +<TR> +<TD>HTTP</TD> + +<TD>80</TD> +</TR> + +<TR> +<TD>SMTP</TD> + +<TD>25</TD> +</TR> + +<TR> +<TD>HTTPS</TD> + +<TD>443</TD> +</TR> + +<TR> +<TD>FTP</TD> + +<TD>21</TD> +</TR> + +<TR> +<TD>IMAPS</TD> + +<TD>993</TD> +</TR> + +<TR> +<TD>NNTP</TD> + +<TD>119</TD> +</TR> + +<TR> +<TD>NNTPS</TD> + +<TD>563</TD> +</TR> +</TABLE> + + +<P> +</BODY> +</HTML> |
