Chaing Remailers (instructions) [long]



Note-1: [RRT- stands for Request-Remailing-To:, most remailers also
         accept Anon-To: ]
Note-2: [You is in this doc [email protected], 
         substitute that adress for your own if you 
         want to receive the test message yourself]


First you should test only one remailer:

you > remailer 1 >> RRT- you

*************************************************
This is what you send:

-->

> From: [email protected] 
> To: [email protected]
>    
> ::
> Request-Remailing-To: [email protected]
>    
> Test of remailer at alumni.caltech.edu

*************************************************

This is what you receive from alumni.caltech.edu:

-->

> From: [email protected]
> To: [email protected]
>        
> Test of remailer at alumni.caltech.edu

*************************************************

If this is succesful you add another remailer:

you > remailer 1 >> RRT- remailer 2 >>> RRT- you


This is what you send:

-->

> From: [email protected]
> To: [email protected]
>    
> ::
> Request-Remailing-To: [email protected]
>     
> ::
> Request-Remailing-To: [email protected]
>    
> Test of remailer at alumni.caltech.edu and RRT xs4all.nl

*************************************************

        Remailer [email protected] will receive this message from
        [email protected]

-->    

> From: [email protected]
> To: [email protected]
>         
> ::
> Request-Remailing-To: [email protected]
>         
> Test of remailer at alumni.caltech.edu and RRT xs4all.nl

*************************************************

    Because the message has the header pasting tokens [::] 
    the remailer at xs4all.nl knows where to send it to.
    
        You will receive this message from xs4all.nl
-->        

> From: [email protected]
> To: [email protected]
>         
> Test of remailer at alumni.caltech.edu and RRT xs4all.nl

*************************************************

You can keep adding remailers this way, everytime you receive
a test message back you add another remailer: if you stop receiving
test messages, the last remailer added is most likely "down". You can
check that by using that remailer directly.

*************************************************

The above is simple unencrypted remailing. If you want to have an
encrypted chained remailing, you first have to "design" the chain.

    0] from your PC send to alumni.caltech.edu
    1] at alumni.caltech.edu RRT jpunix.com
    2] at jpunix.com RRT vox.hacktic.nl
    3] at vox.hacktic.nl RRT [email protected]
    

{Stage 3:} This is actually the first message you make. 
                             
-->

> ::
> Request-Remailing-To: [email protected]
>     
> Test of PGP'ed remailing trough caltech, jpunix and vox.

*************************************************

The above is encrypted with the PGPpubKEY of vox.hacktic.nl and will
result in this:

> -----BEGIN PGP MESSAGE-----
> Version: 2.6 for VoX Labz.
> 
> hIwCWd90FI1WkT0BA/9I6ILVhl5ZpsgKgHye+ng9CokwzdW1pMgcd0ecigppAODe
> 53LlyVw/hl1ERYIzWW9W4vnuh7sLgu9XjxB515FtT5VSyZLZrhKIF7XtACga2On+
> 1NmsecLTrgXYcc4k0Y+l66Hs06z92yhFvjXruDBS2Pame0VDtgZo+4aPntioDaYA
> AABJsVIWRaJkCib+uek9Pr6GqFP7lwaMqq8XFnFxY42h3Wn3c5DikrzmwKGK5xVs
> hmiZnEhJgXvR7jS2cNNOk/geG4SnUqvMTzpq6w==
> =b0bT
> -----END PGP MESSAGE-----

*************************************************    
    
Then you than proceed to the 2nd stage the message wich has to leave
jpunix.com, so [email protected] knows what to do [decrypt it] is:

-->

> ::
> Encrypted: PGP
>
> -----BEGIN PGP MESSAGE-----
> Version: 2.6 for VoX Labz.
> 
> hIwCWd90FI1WkT0BA/9I6ILVhl5ZpsgKgHye+ng9CokwzdW1pMgcd0ecigppAODe
> 53LlyVw/hl1ERYIzWW9W4vnuh7sLgu9XjxB515FtT5VSyZLZrhKIF7XtACga2On+
> 1NmsecLTrgXYcc4k0Y+l66Hs06z92yhFvjXruDBS2Pame0VDtgZo+4aPntioDaYA
> AABJsVIWRaJkCib+uek9Pr6GqFP7lwaMqq8XFnFxY42h3Wn3c5DikrzmwKGK5xVs
> hmiZnEhJgXvR7jS2cNNOk/geG4SnUqvMTzpq6w==
> =b0bT
> -----END PGP MESSAGE-----

*************************************************

{Stage 2:}

But jpunix.com has to know where to send it to, so the 2nd stage msg is:

-->

> ::
> Request-Remailing-To: [email protected]
> 
> ::
> Encrypted: PGP
> 
> -----BEGIN PGP MESSAGE-----
> Version: 2.6 for VoX Labz.
> 
> hIwCWd90FI1WkT0BA/9I6ILVhl5ZpsgKgHye+ng9CokwzdW1pMgcd0ecigppAODe
> 53LlyVw/hl1ERYIzWW9W4vnuh7sLgu9XjxB515FtT5VSyZLZrhKIF7XtACga2On+
> 1NmsecLTrgXYcc4k0Y+l66Hs06z92yhFvjXruDBS2Pame0VDtgZo+4aPntioDaYA
> AABJsVIWRaJkCib+uek9Pr6GqFP7lwaMqq8XFnFxY42h3Wn3c5DikrzmwKGK5xVs
> hmiZnEhJgXvR7jS2cNNOk/geG4SnUqvMTzpq6w==
> =b0bT
> -----END PGP MESSAGE-----

*************************************************
    
The above is then encrypted with the PGPpubKEY of jpunix.com
*************************************************

{Stage 1:}

This new encrypted message gets the headers for caltech to remail:

-->

> ::
> Request-Remailing-To: [email protected]
> 
> ::
> Encrypted: PGP
> 
> -----BEGIN PGP MESSAGE-----
> 
> and the PGP encrypted message from {stage 2}
> 
> -----END PGP MESSAGE-----

*************************************************

{Stage 0:} the message you send to alumni.caltech.edu

is the encrypted message [with the PGPpubKEY of alumni.caltech.edu] of
stage 1 plus a Encrypted: PGP header.

-->

> To: [email protected]
> 
> ::
> Encrypted: PGP
> 
> -----BEGIN PGP MESSAGE-----
> 
> and the PGP encrypted message from {stage 1}
> 
> -----END PGP MESSAGE-----

*********************************************************************

This you send from your PC to [email protected] :

If you finger [email protected] you will
receive a list of active remailers and their peculiarities.

If you finger [email protected] and/or
              [email protected] you will
              receive a list of uptime statistics. 

Hope this helps.

Happy Remailing ...
