Thrasher and X-No-Archive test results
|
|
| Thrasher Remailer 2005-04-08, 2:45 am |
| After various tests I have come to the following conclusions for getting a
post through thrasher with the X-No-Archive header present.
A post using X-No-Archive: Yes
the header will not be present in the post.
A post using X-No-Archive: yes
the header will be present in the post but will have changed to X-No-Archive: Yes
This seems to be peculiar to the thrasher remailer and I have found the above
to be true in all the tests that I have made.
The Google help page states to use X-No-archive: yes (weird, but am trying
this in this post for the first time) and the use of X-No-Archive: yes which I
can't find a way to do through thrasher, although its metamorphosed form
X-No-Archive: Yes appears to do as supposed.
I hope that these observations are useful.

More than "useful". I tried what you suggested, and it worked every
time. I repeated the same with random remailers and found that Panta
behaves in exactly the same way as Thrasher. As far as I know, we are
the only remailers running this version of Reliable. That should make
it quite easy to isolate and rectify the problem.
Once again, thanks for the time and effort you have put in. A cheque
is in the mail...

Mea culpa !
A missing lcase() was the culprit, just compiling new version.
Should be in the downloads section very soon.
Thanks for finding the bug,

Fix for two lines in Panta's modified Process.bas
HashHeaders:
[. . .]
'***** panta-admin *****
'read hashcash and x-no-archive state
Case "x-hashcash"
RemH.Hashcash = c
Case "x-no-archive"
'If c = "yes" Then RemH.Xnoarchive = True
If LCase(c) = "yes" Then RemH.Xnoarchive = True
'***** panta-admin *****
Private Function BuildHash(RemH As RemHType) As String
[. . .]
'***** panta-admin *****
' we need to set the X-NoArchive flag manually as we have removed the header
'If RemH.Xnoarchive = True Then BuildHash = BuildHash + "X-No-Archive: Yes" + vbCrLf
If RemH.Xnoarchive = True Then BuildHash = BuildHash + "X-No-Archive: yes" + vbCrLf
'***** panta-admin *****
Ciao!

Hi !
New version is at
http://www.panta-rhei.dyndns.org/downloads
Let me quickly explain why this problem occured in the Panta Reliable mod:
I have implemented an easy way for the operator to request hashcash tokens
for news posts.
In the early days I tried several ways of what to do if no valid hashcash
is present, and one of them was to force x-no-archive to yes.
For this to work I had to read the original header (if present) and
converted it to bool true or false.
After processing I added the header again, and set it to yes if no hashcash
was present.
So basically the reliable mod will rewrite the x-no-archive header on all
news posts.
The error was in the header parsing, here:
If c = "yes" Then RemH.Xnoarchive = True
Which should have been something like:
If Trim(LCase(c)) = "yes" Then RemH.Xnoarchive = True
This is in the new version, which now runs on Panta Rhei.
Thrasher Admin, sorry for the cock-up, hope you are happy to get the new
version.
Thanks to the original poster for finding this,
Cheers,
panta-admin

Yo PA! would you *please* make the source available for your modified
Reliable???? I'd *REALLY* like to use it but I am just paranoid enough
that I insist on compiling from source after I have examined it
thouroughly.

No worries. Thanks for the prompt fix.

Agreed.

By not providing the source code to his modified version of
Reliable, he's violating the GPL which Reliable is released
under.
I know that panta admin has the best intentions. He's probably
waiting to make sure his modifications are stable or whatever.
However by not providing the source to those who want it, he is
still violating the license regardless of his intentions.
