Fix in Autohandler for working with AuthNTLM

With testing at another customer site, I found that sometimes Apache2::AuthNTLM does not provide the username information when a web page has already been authenticated. Perhaps it might do it with every page if I turn off the 'cache' parameter in the return headers. Anyway, the new autohandler will rely on the session uuid to keep authorization going on pages which AuthNTLM does not return a username.

Web Page Authorization with Perl and Mason

The monitoring server described in these various articles uses an Apache 2.0 based web server loaded with mod_perl and page templating language based upon mason. I'll put up on this site the other pages I have, but for the moment I just wanted to get the authentication stuff documented.

Authentication starts in /etc/apache2/sites-available/default with the following configuration: 

        
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all

          PerlAuthenHandler OneUnified::AuthNTLM
          AuthType ntlm,basic
          AuthName domainname
          require valid-user

          PerlAddVar ntdomain "domainname globalcat1 globalcat2"

          PerlSetVar defaultdomain domainame
          PerlSetVar splitdomainprefix 1
          PerlSetVar ntlmdebug 0
          PerlSetVar ntlmauthoritative 0
#          PerlSetVar fallbackdomain fallbackdomain

In this configuration, you'll need to replace 'domainname'and 'globalcatx' with your netbios based domain name and global catalog server dns entries.

When running this security configuration, a web browser's security may need to be changed to make this a trusted site so that a user's ntlm security information will be exchanged.

AuthNTLM.pm is a wrapper around the CPAN perl module Apache2::AuthenNTLM. It pulls the username and domain information out and passes it along in the object's pnotes() method to the actual mason processing.

autohandler is mason's root file that is executed for every page serviced in a web site. As such, it can be used to perform page initialization, authentication, and authorization. It also holds the defaults for the pages of the site, and is used in an object oriented fashion to let other pages override the defaults. This particular one maintains session and user variables, and with some upcoming additions, will help to maintain session state. (You may need to use FireFox to download the file as Internet Explorer interprets the file for what it isn't.)

The autohandler file calls isADGroupMember.pm to perform the actual user and group authentication and authorization in Active Directory. The routine knows how to recursively search groups within groups.

The autohandler stores session variables in a PostgreSQL database with the following schema: 

-- Table: users

-- DROP TABLE users;

CREATE TABLE users
(
  pkuserid character(36) NOT NULL, -- guid of user
  userdomain character varying(100) NOT NULL,
  authtype character varying(10) NOT NULL, -- ntlm, basic, ldap, db, builtin
  pwdclear character varying(20),
  pwdmd5 character varying(50),
  CONSTRAINT pk_users_pkuserid PRIMARY KEY (pkuserid)
)
WITHOUT OIDS;
ALTER TABLE users OWNER TO oneunified;
COMMENT ON TABLE users IS 'User list';
COMMENT ON COLUMN users.pkuserid IS 'guid of user';
COMMENT ON COLUMN users.authtype IS 'ntlm, basic, ldap, db, builtin';

-- Table: sessions

-- DROP TABLE sessions;

CREATE TABLE sessions
(
  pksessionid character(36) NOT NULL,
  fkuserid character(36) NOT NULL,
  ts timestamp without time zone NOT NULL,
  groupname character varying(50),
  grouppermission boolean,
  CONSTRAINT pk_sessions_pksessionid PRIMARY KEY (pksessionid),
  CONSTRAINT fk_users_pkuserid FOREIGN KEY (fkuserid)
      REFERENCES users (pkuserid) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE NO ACTION
)
WITHOUT OIDS;
ALTER TABLE sessions OWNER TO oneunified;
COMMENT ON TABLE sessions IS 'Contains active web sessions.';

-- Insert these default entries
insert into users ( pkuserid, userdomain, authtype, pwdclear )
  values ( 'admin', 'local', 'builtin', 'admin' );
insert into users ( pkuserid, userdomain, authtype, pwdclear )
  values ( 'guest', 'local', 'builtin', 'guest' );

Trading Site of the Day -- Some Random Picks

Here are some notes and web locations I've come across that appear to be relevant to Active Day Traders and Automated Trading Strategies.

I've recently opened an account with Genesis Securities and have downloaded their Laser trading software. There is a great deal of trading flexibility in that software. It also introduces some trading subtlties I've not dealt with before. There is flexibility in which markets to which orders can be sent, and the types of orders to be sent.

Routing Guide is a useful guide to ECN's, what markets they cover, how to grade with them, and a few helpful hints on order placement.

Electronic Communication Network (ECN) are important sources of liquidity.

Here are some more articles from Answers.com on Scalping and Day Trading.

A forum post at Elite Trader mentioned Bull Investors. They have some various live feeds and intra-day trading notes.

Aging Concepts in Genetic Programming

I've used some Genetic Programming in the past to assist with some trading optimizations. As part of calculating the population of a new generation, I've used a concept of elitism to keep the best individuals propogating to new generations. Some researchers seem to think this is a good thing, where others think this is a bad thing. As there was no real consensus about this, I chose the side saying this is a good thing. Now that I've heard about a concept of being able to age individuals, perhaps I can modify how I build new populations somewhat.

Installation and Configuration of PGAdmin on Debian

A multiplatform GUI tool called pgAdmin is available for managing and querying PostgreSQL databases. It is available at www.pgadmin.org.

For Windows platforms, an executable installation program is available.

For Debian platforms, don't install the package from the Debian web site. Instead, through a little config file magic, a Debian package direct from pgAdmin can be installed.

First, you'll need to determine your nearest mirror. Choose a mirror, and past it in the following format into /etc/apt/sources.list: 

deb [MIRROR URL]/pgadmin3/release/debian testing pgadmin

You should then be able to run the following commands to get it installed: 

apt-get update
apt-get install pgadmin3

You can start pgadmin through the command pgadmin3. In order to manage the database, you'll have to login first as postgres, or try this simple expedient (warning this is not very secure for your database). Place the following line into /etc/postgresql/7.4/main/pg_hba.conf: 

host    all         postgres    127.0.0.1         255.255.255.255   trust

In pgadmin, you'll need to connect to the database. You can connect to a specific database through existing credentials, or if you are looking to create new databases, you should connect via the above credentials and connect to template1.

Trading Site of the Day -- Day Trader's Bulletin

Although Day Trader's Bulletin looks like it hasn't been updated in a while, it still contains useful and timely information. For example, in my own research, I've discovered the use of the INDU and the TICK as useful bellweather's for day trading. Knowing What Indicators to Monitor goes into additional details of these indicators plus adds a few more, such as: SPX (S&P 500 Cash), Down Transports (TRAN), selected stock issues, and intraday highs and intraday lows. The article goes on for a few additional pages in review of other things to keep an eye out for.

Besides that one article, there are many more interesting ones. If you'd like them all in one document, you can download Tips, Tricks & Techniques for Daytraders.

Peak Selection, Pivot Analysis, and Fibonacci

Sometimes it takes a while to realize that how various things work together. The light has dawned. I wrote some code to do peak detection a while ago. By using this tool over multiple time frames, and associating Fibonacci intervals on the advancing lines, one can automatically search out possible turning points. A CBOT article called Trading the CBOT mini-sized Dow - Master Technician Techniques provides the ground work for how this would be done from an analytical perspective. These possible Fibonacci turning points can be strengthened if some of them overlap calculated pivot points. Further strengthening is achieved if Fibonacci turning points occur at the same location over multiple time intervals. As the author, John Person, says in the article, "Combining Pivot Point numbers with the Fibonacci analysis we have a much better outlook and confirmation of Support and Resistance targets."

CBOT has some links to additional strategies.

In an article at National Futures, writes an additional article on Using pivot points to predetermine support and resistance price levels. He ties them in with the TRIN, TICK, and VIX indicators along with a reference to candlesticks.

Connecting to Debian X Windows with Cygwin/X

On some of the monitoring servers I install, KDE is installed and running. For remote management, it is nice to connect to it remotely via Windows XP host. To do so, I did the following:

  • On the monitoring server, edited /etc/ssh/sshd_config, and changed X11Forwarding to yes. This is necessary for getting DISPLAY set properly.
  • Reload sshd after change in setting: /etc/init.d/ssh restart
  • Downloaded and installed Cygwin. During installation, I made sure that under the X11 heading, that the xorg-x11-base package was selected
  • Started Cygwin with the desktop icon
  • In my Cygwin home directory: cp /etc/X11/xinit/xinitrc .xinitrc
  • In my Cygwin home directory, Started the xwindows process with: startx
  • In the new GUI window, connect to the monitoring server with: ssh -Y -l username serverip
  • It is possible to run 'startkde' but on my setup, currently, it doesn't appear to work quite right, but I can run individual XWindows based programs by starting them with their command line names

vBulletin was helpful in troubleshooting some connectivity issues.

Government Security has some more info on Cygwin, X11 Forwarding, and SSH. The site was either copied to or from a Linux Journal article.

For using vnc and securely remoting vnc, Debian Administration is helpful.

Be a Price Maker, Not a Price Taker

Benson Shapiro wrote an article at the Harvard Business School called commodity Busters: Be a Price Maker, Not a Price Taker. In the article, he very elegantly writes about the importance of differentiating oneself from the competition. Rather than competing head to head, it is wise to pick a niche and become a monopolist in ones own right.

He provides a series of steps for doing it right:

  • Create customer value
  • Choose your customers
  • Be different
  • keep it simple
  • Determine customer value
  • Deliver on your promise
  • Be courageous

Low Latency Data and Trades

SmartQuant was recently purchased by QuantHouse. Quanthouse provides low latency data and is using the SmartQuant framework in their product line.

That is all well and good, but if one has low latency data, one should have good executions as well, particularily if one is performing automated, high frequency trading. So what does one do: find a low latency data source and a separate excellent execution broker, or does one find a provider who can do both? I suppose there are organizations who only need the data side of things, but I'm looking for both data and execution.

I'm currently using IQFeed for data and Interactive Brokers for execution. I think I can do better than that. I'm currently looking at:

  • Genesis Securities: appear strong on equities but weak on futures coverage, and have a QuantDeveloper API
  • RedSky Financial: appear to be be strong on both futures and equities, but I don't think it has a QuantDeveloper API link (I'd have to write one)
  • Photon Trader: strong on futures, and may have a QuantDeveloper API link

NetFilter Documentation, Tutorial and Pictures

The packet flow through netfilter has been a little hazy for me. Today I received enlightenment. Pablo Neira Ayuso has a paper called Towards 4th Generation Linux Firewalling Tools. On page 10 of that presentation is an excellent drawing of the iptables paths and what is performed in each path. It clearly shows PREROUTING, FORWARD, INPUT, OUTPUT, and POSTROUTING.

In the cross references on that page are a couple of good links:

While here, and on an unrelated topic, here is a Packet Shaping HOWTO. Now if I could just find a utility that can chart who is doing what with what protocol in real time. In isn't open source but later I did come across ObjectPlanent's Net Probe as something that could do the job.

Here are a few interesting commands to use when iptables is active:

  • cat /proc/net/dev
  • cat /proc/net/netstat
  • cat /proc/net/ip_conntrack
  • cat /proc/net/sockstat
  • iptables --list -v

A paper called Netfilter Performance Testing is a good one which discusses the testing of netfilter and the various tools employed to do so.

The NetFilter site is at www.netfilter.org. For monitoring connections conntrack, ulogd2, and libnetfilter_conntrack are projects to look at.

Intellos Network has a souped up Conntrack Viewer for 2.4 kernels. I wander if it will work on 2.6 kernels.

Implementing Live URL Tracking

To monitor browsing habits of company users, and to use the information for possible site blocking or traffic limiting with MasterShaper, URLSnarf along with a Perl script can be used to log specific items to a database and place the full capture results into a log file. The log file will be rotated with logrotate.

The Perl module Logfile::Access is key. On my machine it needed to be manually installed: 

perl -MCPAN -eshell
  install Logfile::Access 
  # a missing file will be encountered
  exit
cd ~/.cpan/build/Logfile-Access-1.30/Access.pm
nano Access.pm 
  # change line 38 to '/etc/mime.types'

Sniffing, Security, Penetration Testing

For my reference, here is a compendium of interesting sites I encountered today:

[/OpenSource] permanent link

Tracking What Web Sites Users Visit

As part of the monitoring package, we are interested in recording which web sites that users are visiting. The first step is to capture the urls. The second step is to process and report the urls.

It took a while, but I came across DebianHelp. Among a bunch of other network diagnostic tools, it made mention of dsniff. It is a composition of the following tools:

urlsnarf was the tool for which I was looking. For usage, it does have a man page. The whole toolset can be installed with: 

apt-get install dsniff

I now have urlsnarf logging to a file. I still need to do log rotation with it.

I am now looking at various ways to process the result. I was thinking of manually using Logfile::Access to parse the lines and put stuff into a database. Then I got to looking around at log file analyzers like visitors or awstats, but they don't provide a breakdown of sites by user. I think I'll roll my own with the perl library already mentioned.

Driftnet: Watching Your Surfers

This tool puts a network interface into promiscuous mode and looks for image files. Any image files found are displayed as a continuously changing mosaic on the desktop. It has the ability to listen a tond keep mpeg and sound files as well.

On my monitoring server, I have eth1 connected to a switch spanned port which in turn listens on the internal firewall interface. This captures all the media files that users are bringing in from the internet.

Installation is easy: 

apt-get install driftnet

To run is even easier: 

driftnet -i eth1

Original files are found at Driftnet. This sites has other interesting software such as proxies, mail impersonators, visual formatting, graphics, and more.

I found this little treasure through a where some other nifty monitoring tools can be found.

iftop: Display Bandwidth Usage on an Interface

iftop is an interesting command line utility for tracking traffic on an interface. tcpdump is good for looking at packet content in real time, this is good for looking at what makes up traffic bandwidth in realtime.

Installation is easy: 

apt-get install iftop

I have second interface on the monitoring server which is listening to what ever traffic passes in and out of the internal interface of the firewall. The switch port connecting to the firewall is 'span'd to the monitoring server's eth1. This allows one to monitor all components of inbound and outbound traffic.

Here is the command I used for looking at generating a bar chart of traffic details: 

iftop -i eth1 -F 10.0.0.0/255.0.0.0 -P

The -F parameter provides an indication of what is internal traffic and what is external traffic. The -P parameter shows the ports in each flow. For run-time commands, take a look at 'man iftop'.

Darvas Results at EOD 2007/03/09 with EOD Signal of 2007/03/08

In comparison, the Dow Jones Industrial Index opened at 12262, had a higher high of 12330, had a higher low of 12228, and closed up for the day at 12276.

The equity curve for today's Darvas ended up down rather than up, even though the Dow was up marginally. For my own trading, I added Thursday's symbols to Friday's symbols. ON that group, overall, I ended up even for the day. I did see some opportunities to take some profit, but left things in place instead. I think, on this set of stocks, day trading might be more profitable: getting out when some good dollars have accumulated, waiting for the Dow to find a low, and then getting in again.

Trading Blox hosts the Trader's Roundtable which is a forum devoted to the discussion of mechanical trading systems and related topics.

Perl Based Active Directory Authentication and Authorization

Most of the customers in which I install the monitoring server have an Active Directory based organization. As such, the best mechanism for authenticating users onto the web pages of the monitoring server is to check that they are valid members of an active directory domain. Authorization to certain specific pages of the monitoring server can then be authorized through group membership.

isADGroupMember.pm is a Perl Module designed to authorize a user through Active Directory group membership. It performs a recursive group lookup to ensure the user is somewhere in the hierarchy. It returns a 1 if the user is found in a group, and 0 if no match is found.

You'll need to update four search parameters at the top of the module in order to work with your Active Directory Organization. There is a base search path to act as the root of the search. A user name and password are required for gaining access to Active Directory. This will require appropriate rights to perform it search. There is a bind address used for connecting to a global catalog server, which can be an ip address or a fqdn.

The user name will be a SAMAccount formatted name. The same for the group name. Each are expanded out to their respective DistinguishedNames, which are then used for matching purposes.

The AuthNTLM module can be used for automatically supplying the user name used in the lookup. In the solution I'm building, AuthNTLM will take the user name it automatically obtained from the browser session and place it into a session record in a database. Mason's autohandler will then pull out the username when it pulls session information and then use isADGroupMember to authorize access to any given web page.

Darvas Results at EOD 2007/03/05 with EOD Signal of 2007/03/02

In comparison, the Dow Jones Industrial Index opened at 12111, had a lower high of 12188, had a lower low of 12039, and closed down for the day at 12050.

The Dow did a fine job of going up and down over the course of the day. It did finally end down for the day.

The results, as shown below, indicated a slightly negative exit for the day. The equity curve followed the Dow reasonably well. So, if we had mostly negative sentiment for the day, getting out around 10:20 or 11:20 would have been good calls for a positive return.

Trading Site of the Day -- Option Strategies: Profits in a Consistent Universe

I havn't tried the strategy myself, but the Option Strategies offers up simple options transactions with guaranteed results each month. They use a set of 13 underlying instruments and offer up various options trades for this set of symbols. In their historical profiles, some months are not traded, but for the months that are traded, things seem to be profitable. They offer up their system for a one time fee of $999. Any one tried them out?

Apache Web Page NTLM Authentication

In continuation of a previous article regarding NTLM authentication and authorization of web pages on an Apache Web Server, I've made some progress with integration.

The web server will now automatically accept MS IE users with passthrough authentication so they are automatically authenticated to view web server pages. Well... users who are hardcoded currently. All other users are rejected.

I used the perl module Apache2::AuthenNTLM from CPAN, and wrapped a module called OneUnified::AuthNTLM around it to obtain some hooks into the original module's operation.

Here is the code I inserted into /etc/apache2/sites-enabled/000-default in order to activate the module: 

        
          PerlAuthenHandler OneUnified::AuthNTLM
          AuthType ntlm,basic
          AuthName ntdomainname
          require valid-user

          PerlAddVar ntdomain "ntdomainname globalcat1 globalcat2"

          PerlSetVar defaultdomain ntdomainname
          PerlSetVar splitdomainprefix 1
          PerlSetVar ntlmdebug 0
          PerlSetVar ntlmauthoritative 0
#          PerlSetVar fallbackdomain fallbackdomain

I originally used the fallbackdomain to invoke a secondary login prompt for non domain members, but it appears to lock the module up for some reason. It is commented out for the time being.

For now, OneUnified::AuthNTLM overrides the verify_user subroutine and manually accepts certain userid's. The next step will be to incorporate the group look up code.

Not all of them are used at the moment, but here are some Perl modules for use with session management. They go into the /usr/local/lib/site_perl/OneUnified directory.

  • AuthNTLM.pm: wrapper around Apache2::AuthenNTLM
  • Const.pm: used in the Mason autohandler file (to be introduced later).
  • Session.pm: will handle session management stuff
  • ValidateFields.pm: some web form validation checks
  • ou.sql: latest database schema for various things, including session management and the ciscowatcher.pl script
