Subject: Problems with SSL via Proxy
Message-ID: <1316634348.23945.23.camel@localhost>

Hello,

I am having trouble trying to use Web Polygraph with a Proxy.

I seem to have tracked it down to Web Polygraph not sending a Host
Header with the request and so the Proxy rejects the connections.

I have captured the network traffic during this to see what is happening
and I can see that for a request sent from my browser the Host Header is
sent but not when a request comes from Web Polygraph.

>From Web Polygraph to Proxy:

CONNECT 192.168.29.104:443 HTTP/1.1
Proxy-Connection: close

>From Browser to Proxy:

CONNECT 192.168.29.104:443 HTTP/1.1
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.9.2.22)
Gecko/20110905 Ubuntu/10.04 (lucid) Firefox/3.6.22
Proxy-Connection: keep-alive
Host: 192.168.29.104

Here is an extract from my polygraph.pg file so you can see what I am
trying to do. Is there some configuration missing? Been stuck on this
problem for a while, originally had a problem trying to jsut run basic
SSL tests. When going direct from Client to Server (no proxy involved),
web-polygraph runs fine. If you require any further information please
do let me know.

I am running v 4.4.0.

SslWrap wrap = {
	protocols = [ "SSLv3", "TLSv1" ];
	root_certificate = "/opt/home/user/CA-priv+pub.pem";
	ciphers = [ "ALL:HIGH: !SSLv2: !aNULL: !AES128-SHA: !AES256-SHA:":
100% ];
    	rsa_key_sizes = [ 512bit, 1024bit, 2048bit ];
	ssl_config_file = "/opt/home/user/myssl.conf";
    	session_resumption = 40%;
    	session_cache = 100;
};


DnsResolver dr = {
    servers = [ '127.0.0.1:53' ];
    timeout = 5sec;
};


Server PlainServer = {
        kind = "HTTP";
        contents = [ cntJPG: 26%, cntGIF: 28%, cntPNG: 9%, cntPDF:
0.05%, cntZIP: 0.22%, cntMalware, cntEXE: 0.43%, cntSWF: 1.9%,
cntJavascript: 32% ];
        direct_access = contents;
	addresses = [ '192.168.29.104:8080' , '192.168.29.104:80' ];
};

Server SSL = PlainServer;

SSL = {
	kind = "HTTPS";
	addresses = [ '192.168.29.104:443' ];
	ssl_wraps = [ wrap ];
};

Robot R = {
        kind = "robot";
        pop_model = { pop_distr = popUnif(); };
        recurrence = 15% ;
        req_rate = 1/sec;
	ssl_wraps = [ wrap ]; 
	origins = [ PlainServer.addresses, SSL.addresses ];
         http_proxies = [ '192.168.111.42:8080' ];
	addresses = [ '192.168.29.101' ** 200 , '192.168.29.103' ** 5 ,
'192.168.29.105' ** 2 , '192.168.29.107'  ** 200, '192.168.29.109' **

This is a bug indeed.  Polygraph never sends Host header in CONNECT
requests, though RFC 2616 requires client to send Host header in any
HTTP/1.1 request.  Apparently, many proxies ignore the missing Host
header and use the URI.

Please try the attached patch and let me know if it helps.

http-connect-host-header-v4.4.0.patch - patch for Web Polygraph v4.4.0

    Send Host header in HTTP CONNECT requests.

    Per RFC 2616, a client MUST include a Host header field in all
    HTTP/1.1 request messages.  Before the change, Polygraph did not
    send Host header in CONNECT requests.

Log files should go after all other options on reporter command line.
This should work:

./polygraph-reporter --label "squid" --plotter /usr/local/gnuplot/bin/gnuplot /tmp/*.log

Hi Dmitry
 Thanks for your answer! the report was generated, however the figures are
not loaded....:

*"**Figure 'Document hit ratio trace' not available: something went wrong
while generating the graph"*

In the console that i ran the command, i get this errors messages:

t.gp", line 1: unknown or ambiguous terminal type; type just 'set terminal'
for                   a list

error: cannot plot

plot file was:

Is necessary set something in gnuplot? =/

Thanks for support.

I guess the gnuplot is built without PNG support.  Here is what I get on
my system:

  gnuplot> set term png small
  Terminal type set to 'png'
  Options are 'nocrop small size 640,480 '
  gnuplot> set term qwe small
                    ^
           unknown or ambiguous terminal type; type just 'set terminal' for a list

Consider using gnuplot package that comes with your system.  It should
have PNG support.  Otherwise you need to rebuild gnuplot with PNG
support enabled.

  Dmitry

Subject: Digest authentication support?
Message-ID: <008f01cc7ee9$85510160$8ff30420$@com>

I'm a new user and I'd like to test a squid-proxy which uses digest
authentication.

 

I didn't see it in the documentation or any google searches, I wonder if
digest auth is supported in polygraph?

 

Thanks,

David

Unfortunately, Polygraph supports only Basic, NTLM and Negotiate HTTP
authentication schemes.

Support for Digest authentication scheme would be a nice feature for Web
Polygraph.  But so far nobody had much interest in it.

For what it's worth, Squid does support Basic and NTLM schemes.  So you
may try testing with them instead of Digest.

Hi Everbody

*i plan to use polymix-3.pg to run a performance test of my squid proxy.
**I am using the same machine to run  client and server, (*initially)* in
the same proxy **network .
Before *run polymix, i already read this :
http://www.measurement-factory.com/docs/PolyMix-3/ , however i still have
some questions :


1 - Where i set objects sizes (html, figures and download) ?
2 - What variables must be defined? And which files? (cause i set up only
polymis-3.pg)
3 - Is there any additional procedures that must be executed before the
polygraph?


Best Regards

Sarah Milani

PolyMix are complex workloads with many Robots and Servers.  Usually, a
single machine is not enough to run high load tests because Polygraph
reaches CPU or network limits.

Consider using the latest version of PolyMix workloads - PolyMix-4.

You should also read PolyMix-3 documentation at [1].

Also, please keep in mind that PolyMix documentation was written for an
old Polygraph version.  Many new features were added to Polygraph since
then.  In particular Polygraph client and server now create required
aliases on start (though, client and server address creation may
conflict if both are run on the same system, use the aka tool to create
them manually in this case).

To set PolyMix-3 parameters, you should copy polymix-3.pg from Polygraph
installation (e.g. Debian package has it in
/usr/share/polygraph/workloads/) or tarball somewhere and edit it.

Everything is configured in the workload.  Polimix-3.pg includes other
workloads which have all the details.

Object sizes are defined in contents.pg.  But you should not edit it
directly.  Instead copy polymix-3.pg somewhere and put all changes
there.  You can set PGL fields like:

  ...
  // include all the boring details
  #include "polymix-3-guts.pg"

  // customize some fields
  cntImage.size = exp(10KB);
  ...

> 2 - What variables must be defined? And which files? (cause i set up only
> polymis-3.pg)

PolyMix workloads have few parameters that you need to set.  Most have
appropriate default values.  All undefined parameters are in
polymix-3.pg and have comments.

You need to configure routes on the proxy so it can reach Polygraph
Robots and Servers.  If you run without a proxy, routing needs to be
configured on client and server systems.

You may also need to adjust system configuration (e.g. network buffers
size, open file limit).

  Dmitry

Sorry, this would not work.  Since cntImage is _used_ in
polymix-3-guts.pg, you cannot customize it after use.  The Server agent,
for example, will retain the wring/old settings.  There are no pointers
in PGL.

If guts customization is needed, a better approach is to literally
include the polymix-3-guts.pg file (i.e., insert its contents) into your
copy of polymix-3.pg and then edit whatever is needed.

  Dmitry
