Hmm, I don't know how that work. Can you get a trace of the traffic
that passes between you <-> RabbIT <-> ms proxy.
Either enable the HTTPSnoop filter on both incoming and outgoing
traffic or use a network snooper like Ethereal.

I've never tried it so I would not know.

Also does ms proxy use some kind of encryption other than basic on
the name:password pair?

[Rabbit-proxy-users] Rabbit behind MS Proxy Server

[Juan C. L. G. <jua...@ho...>]

Hi, I just installed RabbIT in a Wi2k server at office and plan to use it 
for remote (modem and CDPD) connections.  So far the proxy is configured and 
I´m able to browse pages of internal servers.

I´m now having problems defining my office´s proxy server so I can reach 
pages at the Internet.  It´s a MS Proxy Server with domain user 
authentification.  I put the proxy name and port in the rabbit.conf file 
without any user:password in it, hoping that rabbit will ask me for the 
password of the remote proxy, but every with every request I get a blank 
page.  Putting my own user:password pair didn´t help either, same results.  
Maybe Rabbit doesn´t like having to talk with a MS Proxy server?

Ok, you are trying to use rabbit as a web server, which it is not.
Enable proxy (edit->preferences->advanced->proxies for mozilla,
something similar for IE).

Maybe someday Ill fix that...

[Rabbit-proxy-users] Rabbit FileSender problem

[<mi...@gb...>]

Hi - I wonder if anyone can help. I've installed Rabbit2 (most recent
download as of today from the website). My problem is that none of
the FileSender elements seem to be working.

For example, when I plug in this URL 
http://proxyname:9666/FileSender/public/smallRabbIT2.gif
I get simply a broken image logo. Using 'open image' it turns out that what
was actually sent to the browser was the following:

400 Bad Request
Unable to handle request:
java.net.MalformedURLException: no protocol: /FileSender/public/NoAd.gif

I wonder if anyone has any ideas?

Best wishes,

It didn't seem to make much difference.  If you look in
my last e-mail, you'll see I was having problems with
Netscape and Mozilla both when it was and was not in
cache.

Seems you have a cached copy and mozilla tries to revalidate the
cached copy. That should work I think.

And if you clear the mozilla cache everything gets ok once again.
Hmmm. Ok, this sounds like a bug, will have to investigate a bit
more. In the meantime dont mix surfing with and without proxy unless
you also clear the browser cache when you switch....

Well, different hosts means different resources so they should be
treated independantly. You dont have that file cached in mozilla so
it does not try to revalidate.

Given above info that makes sense, but should be marked as a BUG...

Well RabbIT uses keepalive whenever possible so that is as it should.
Keepalive to clients and keepalive to servers are two independent
things for a proxy. The keepalive time for servers is lower than
keepalive time for clients though.

Well, yes, its quite a heavy process to start an external program and
small images will not see much savings. Even if you save 50% its
still only 1000 bytes...

I forgot to put it in httpoutfilters, below is more info (long).
This time, I had trouble in Netscape, too!  I'm about to blame
Apache, but I've never had anything like this happen without
the proxy, and even when going through the proxy, adding noproxy
in front of the hostname always works.  Here's the HTTPSnoop

Here's what HTTPSnoop saysa about the request from Mozilla.
Mozilla gets a blank page:

Interestingly, enough.  It says that http://www.tco.net/, it's
linked stylesheet and all the images that it loads have null
content type and 0 size.  However, the cache entries for
adios.tco.net have the correct size and content type.

Sometimes, it seems that the Status admin page keeps connections
to www.tco.net listed longer than the browser appears to be
connected, but I can't reproduce this reliably.

I imagine they were just small ones.  I didn't realize that it

Interesting. That site works ok for me, I get a cache file that is
2697 bytes.

What version of RabbIT?
What version/vendor of browser?

Can you enable HTTPSnoop and capture some requests and responses?

What does the CacheStatus-admin page say about that page?

[Rabbit-proxy-users] Empty files in cache

[Micah S. <mi...@cn...>]

Hi, I'm new to rabbit this list, so forgive me if I'm
missing something obvious.  We're testing out rabbit on
a computer here (adios.tco.net), and it mostly works fine.
The main problem is that when we access http://www.tco.net
(hosted on the same machine), we get a blank page.  This
doesn't happen on the first access, though.  When it's
first accessed, everything comes through fine, but a
zero-length file is stored in the cache for that web page
and all of the images it loads.  Then subsequent accesses
of the page return the empty files.  This doesn't seem to
happen on any other web pages (at least we haven't found
any) or even on the same web pages under different names.
I.e. http://adios.tco.net/, http://208.21.241.1/ and
http://www.tco.net/index.html (!) all work fine (except
with the last one, if the images were already in cache
as empty files, they are served that way).  It's got me
baffled.  Below is my rabbit.conf, comments removed.

On a side note, it doesn't seem to convert GIFs to JPEGs,
I'm not sure why.  That is, however, a very minor problem.

Thanks in advance for your help,

Micah

> Can=B4t we implement it??

If you want to implement it, feel free.
I do not have the specification so I currently can not.
Im not sure if it is possible to implement it, it may be that we have
to look at ip-headers to know where to send the request (http/1.1
headers should have a "Host: www.somehost.org", but not all browsers
are http/1.1).

What requests does rabbit get when you turn redirect traffic?
What errors does rabbit give you?

No, RabbIT does not work as a transparent proxy. if you really want
to do that, chain it after a squid or some other proxy that

[Rabbit-proxy-users] Transparent proxy

[<af...@ha...>]

Hello all,

does RabbIT accept transparent proxy?
I set our proxy gateway with RabbIT trying to use it. No success...

I=B4m using it under ipchains script: every connection on port 80 will be=20
locally redirected to port 9666.

Can someone instructs me if it=B4s possible and how to set it up, pleas?

Regards.

[Rabbit-proxy-users] Re;More documentations

[x x <x...@ph...>]

I was trying to examine on why I cant access the web administration of rabbit and found out that it could not somehow see its own identity? sort of.

Example my server name is server.server.com.

In the no ads the gif... example i request foo.com it replaces some adds with it. But there is just an x mark though if I hover on it the links point to sever.server.com/ads gif( Sort of like this I just forgot the actual url)  Now if i try to access the webadmin  the same.

The access log shows this.

66.10.25.11 - - 29/Jan/2003:10:37:04 GMT "GET / HTTP/1.1" 400 -

I can explain the situation much but as i see it it somehow jan relay or is blind about its self. This is also the same reason that the no-ads.gif does not display or the rabbit logo.

Any Idea?

By the way I see some errors also like

[29/Jan/2003:10:36:11 GMT][WARN][Error writing request:java.net.SocketException: socket write error (code=10053)]

Im tested using the latest jdk and also jdk.1.2 1.3 and a lot.

Thanks.

Hello!

It uses the java call "InetAddress.getLocalHost ()". By reading the
source to that it seems to use the DNS, but I havent bothered to read
the real implemenation so Im not really sure about that.

Hmmm, this seems odd, dont have any good ideas...

And you still havent told me what response you get.
What does the error_log say, what does the access_log say and what
does the returned web page look like? If you answear theese questions
maybe I can provide more info.

> By the way does the server identity in the  rabbit.conf affects it?
No, that is only a string that is put in error and admin web pages
the proxy generates (well really in the http header of the
responses...)

Not at the moment unless you (or anyone else) provides such a
handler. I dont think it is much simpler to say that "for image
conversion to work you have to either download imagemagick and use
convert or download SomeJarFile and use jconvert".

When RabbIT was build there were no good image converters, convert is
not the fastest but it handles most formats. If I wanted to I could
drop java/1.1 and go for java/1.4+ only then the java advanced
imaging I/O tools I think. Maybee in the future...

How does Rabbit resolved its own Name?By DNS. Whats the handler responsible for hostname lookup?

I am running a DNS server and my workstation is configured properly. Now if Rabbit is making lookup via netbios or using the hostfile(resolve.conf) then thats the thing I was able to skip. But if Rabbit uses DNS still I am figuring it out why it cant access its own webadmin. By the way does the server identity in the rabbit.conf affects it? 
Do you have plans of incorporating an image transcoding engine in future builds of rabbit instead or relying on imagemagick? A fully java based program would be effective coz it would no longer call out any outside function. (what about incorporating jmagick jconvert?)

Well I very much impressed in you project.Kudos. Regarding user documentation maybe if I make figure out this webadmin and immagemagick problem I can provide some user tips in our site regarding Rabbit.

Hmmm:
GET http://biztech.nikkeibp.co.jp/ HTTP/1.1
HTTP/1.1 200 OK
Server: Netscape-Enterprise/3.6 SP3
Date: Sun, 26 Jan 2003 11:03:26 GMT
Content-type: text/html
Connection: close

The server says that this is normal text/html, no encodding. So
treating the page like ISO8859-1 (latin-1) seems ok from the proxys
point of view.

This also means that your extra filters will not handle this page.
One working solution is to add the dontfilterfilter and add this
page, the other solution is to educate nikkei to use correct
encodings in there responses.

somehting like this:
[Filters]
httpinfilters=rabbit.filter.HTTPBaseFilter,rabbit.filter.DontFilterFilter

use the full qualified name and the port of the system running rabbit
should work. Like for me, when I run RabbIT I mostly run it on my
machine named grunt and run it from a computer in the khelekore.org
domain. I access it like this:

In the browser(mozilla for me) I enable proxy surfing
Edit->Preferences->Advanced->Proxies
[x] manual proxy configuration
	HTTP Proxy: grunt.khelekore.org               Port: 9666


After this I fill in the url to go to:
http://grunt.khelekore.org:9666/

I get a password prompt where I enter the user name and the password.

> Now either with proxy nor without proxy still my browser or any
> workstation cannot access the webconfig.

What response do you get?

Please note that there is a feature that RabbIT only accept the
"first" name it can find for the host. So normally
"http://localhost:9666/" will not work, nor will "http://grunt:9666/"

> Rabbit.conf the imagemagick path ex.convert=c:/Imagemagick/convert

Ok. I dont run windows, but that does not sound very strange.
The dos window normally appends .bat, .com or .exe does it not?

> But  I could not see any changes in the image quality or anything.
Thats odd. Did you get cache hits for thoose images or real requests?

You could also check the access_log to see how RabbIT sees it, you
will get lines like:
127.0.0.1 - - 25/Jan/2003:19:25:12 GMT "GET
http://images.slashdot.org/topics/topicinternet.gif HTTP/1.1" 200 709
imageratio:2039/709=0.34771946

the imageratio is the interesting thing in this case, this images
gets quite much smaller (only 34% is sent).

Seems to work for me. What browser do you use? I use mozilla and just
tested slashdot: go there, shift-reload the page to make sure RabbIT
has all parts, quit mozilla, restart mozilla, clear mozilla cache, go
to slashdot, 13 cache hits, page looks like it should.
So It should work and seems to work.

Maybee, but it will probably take time. I dont have much time to
develop it anymore and Im also quite bad at documentation (API-docs
is ok, but usage-guide is bad..).

I run it without much problems. But it has a few bugs for sure, one
of the more interesting ones have been fixed in the developer release
just recently (will _very_ rarely corrupt POST requests).

Hi. I had been tinkering with Rabbit for weeks and still havent figured out on how the heck will I be able to access the web config (the http:(proxy=port) thing.

Now either with proxy nor without proxy still my browser or any workstation cannot access the webconfig.
Secondly the convert. Im using a win32 system now coz I have some problems with my linux system.I made some changes in the win32 system  (coz it also has the convert command) so that there will be no conflict with imagemagick. I monitored the rabbit error.log and I keep on displaying cannot find convert. I had specified in the Rabbit.conf the imagemagick path ex.convert=c:/Imagemagick/convert
When I changed the line to include the extension ex.convert=c:/Imagemagick/convert.exe , then the error stopped. But I could not see any changes in the image quality or anything.
 Is the compression method of Rabbit OK? Cached objects seems to appear as garbaged when displayed. Im sure this is not a browser related problem .

Lastly, Can you provide a more detailed manual or similar regarding Rabbit.We could surely need one as to figure it out. We are not java programmers that can just navigate easily.By the way have anyone tested Rabbit and run it without a glitch? Thanks.

Okay, here is an example page  http://biztech.nikkeibp.co.jp (tech info
page from nikkei). The proxy "does filter" the page,  but the text
filtered by proxy gets screwed up under iso-2022-jp .

I put sample jpgs for filtered&unfiltered sample webpage at my webpage.

[Rabbit-proxy-users] problems on Japanese multibyte environment

[Hiroki W. <wa...@pa...>]

Hello, all

I'm running RabbIT2 under Japanese environment.
I can see proxy just works fine under Shift_JIS, and EUC encodeing, 
But for some kinda reason, I wasn't able to see pages which are encoded
by iso-2022-jp.

I tried to modify the conf/rabbit.conf by adding
text/html; charset\=iso-2022-jp=rabbit.handler.FilterHandler
text/html; charset\=ISO-2022-JP=rabbit.handler.FilterHandler

at the text/html=rabbit.handler.FilterHandler section. But I couldn't
get proxy worked right.

Do you guys have any idea of why ISO-2022-JP doesn't work well?

I am using Rabbit under jdk 1.2.2 with Linux kernel 2.4.20.

Thanks.

Hmm not sure I understand exactly what you mean here. Can you give a web
page where it misbehaves?

Directory listing sounds like a file://some/path, that should not go 
through RabbIT,
or do you mean something like:
http://kernel.org/pub/linux/ (that page works fine for me through 
RabbIT)....
It could also be useful if you could enable the HTTPSnoop filter for 
incoming request
so I can see what your browser ask for, it may be that it(or RabbIT) has 
a problem with
the http specification...

OK thank you very much. I downloaded the source and compiled it. It
works!!! Thanks a lot.

One thing though... I noticed that if a directory listing is requested
(there is no index.htm(l) ) in the directory, the rabbit returns and
empty page (it sends something like 10 bytes and that is all).
Maybe this is known issue, otherwise, it is excellent. I see the effect
of compression on download speed.

Thanks again
