Reference Clients, the Global Meltdown and CEP

Sometimes I get email from colleagues who ask me why I am working on compiling CEP/EP reference clients.

My reply is that I don’t care must about reported dollar sales because these numbers are, for the most part, meaningless and mythical at this point in time. Large companies sell enterprise licenses and make up allocated numbers for the CEP/EP share of the pie based on a subjective formulation. They can sell an enterprise site license for $2,000,000 USD that includes CEP/EP software and claim 20% is CEP revenue, regardless of if the software is used or not.

Small companies nearly give software away with the hope of developing a strong public reference client, which are few and far between in 2008. Soon, I will start a Google spreadsheet, similar to what we did last year on this topic. Some folks don’t seem to like this initiative because, unfortunately, we will see that for this half of 2008, this year has been very lean for CEP/EP. Some would prefer I blog as a cheerleading evangelist versus an objective analyst. Go Fight Win! Rah Rah Rah!

Much of the current gloomy situation, of course, is because the entire market has fallen and IT spending is down. Financial companies announce record losses. Bankruptcies and restructuring are in the daily news.

In this depressed market, some companies have tried to tie the subprime crash to CEP, somehow implying that CEP would have helped, but that positioning is mostly fantasy. I work in the field of risk management at the corporate level and the current problems are not caused by a lack of technology, it is simply corporate greed - corporations taking high risks to stay competitive in a bull market and then they experience a frighteningly negative reversal during a market free fall.

Of course, the US Federal Reserve did not help matters when they decided to poke a gaping hole in the real estate bubble by dramatically raising interest rates without thinking about how they would manage the consequences, but that is another story! After all, the current top government executives in Washington DC are so politically, scientifically and economically incompetent that all we can do is hold our breath and count the days.

One risk management colleague often says “when then tide is high, you can’t see that the swimmers are naked” and so it is in business. The current problems in the global market are based on human, social, and political errors and incompetence; nothing that technology can cure at this point in the game. So, the entire market is in decline, and folks are overhyping all software to keep the buzz going, as if CEP or SOA or BPM would have helped stopped the current global meltdown. Yes, CEP can stop global warming! Buy one today, save a cute polar bear!

Then again, maybe we only need a CEP engine in Washington; even a simple rules-based one would be good. Naturally, some would suggest that we need Neural Nets and Bayesian analytics; but I think just a simple rules-engine looking out the window that can process if-then-else conditions would be a great improvement over the mind-numbing leadership in Washington today.

rsockd

RSOCKD(8)						      System Manager's Manual							 RSOCKD(8)

NAME

       rsockd - SOCKSified SOCKS server

SYNOPSIS

       rsockd [ -ver | -i | -I ]

DESCRIPTION

       rsockd  is the SOCKSified version of the SOCKS server sockd.  Functionally rsockd is identical to sockd except that it may (though not nec-
       essarily has to) make use of other SOCKS servers to reach some destinations. A number of rsockd's can be strung together or organized in  a
       cascade	or  other  more  complicated structures to serve the needs of a particular network configuration and restrictions.  Obviously this
       complicates the issues and make the setup and maintenance of the firewall more difficult. So use sockd instead whenever you can.

       This document only describes the features of rsockd that are different from sockd. You should read  sockd(5)  carefully	to  gain  a  basic
       understanding of of how the SOCKS server works.

       When  rsockd receives a request, it checks the request again its configuration (in exactly the same way that sockd does) to decider whether
       the request is to be accepted. The primary difference between sockd and rsockd is in how they establish connection to the destination  host
       of  a  accepted	request.  sockd  assumes that it can connect directly to the destination host and proceeds to do so.  rsockd makes no such
       assumption. Instead, it consults another configuration file to decide whether it can connect directly to the particular destination host or
       whether	it  has  to  use a proxy connection through another SOCKS server. In other words, it behaves just like a versatile SOCKS client in
       this regard. Therefore rsockd requires not only the SOCKS server configuration file /etc/sockd.fc or /etc/sockd.conf to decide  whether	to
       accept  or reject a request, but also the client configuration file /etc/socks.fc or /etc/socks.conf to decide how to reach the destination
       host.  If it is a multi-homed version and supports RBIND, it also needs the route file /etc/sockd.fr or /etc/sockd.fr to decide which  net-
       work interface to use for a connection.

       Look at it in a different way, you can think of sockd as a special case of rsockd, one which can connect directly to all destination hosts.
       In fact, an rsockd using the client configuration consisting of only this line

       direct	 ALL  0.0.0.0

       is functinally identical to the regular sockd.

       Anther thing to mention is related to the use of identd. Only the SOCKS server which the requesting host directly connects to can find  out
       the identity of the real user. Suppose user x on host C connects to rsockd on server B which in turn connects to sockd on server A in order
       to reach destination z. Host B can query identd on host C to find out whether the user is indeed x. To host A, the request appears to orig-
       inate  from user x on host B. An identd query from Host A to host B returns the userid that owns the rsockd process on host B, not the real
       user x.

OPTIONS

       See sockd(8).

EXAMPLES

       The follwoing is an example of the client configuration file. See related man pages for examples on server configuration and route files.

       # /etc/socks.conf for rsockd of domain rnd.xyz.com
       #
       # Use proxy connection through SOCKS server on socks.market.xyz.com
       # to reach hosts within market.xyz.com
       sockd	 @=socks.market.xyz.com  .market.xyz.com  0.0.0.0
       #
       # Use direct connect to all other hosts within xyz.com
       direct	 .xyz.com  0.0.0.0
       #
       # Use proxy connection through SOCKS server on gateway.xyz.com
       # to reach all others
       sockd	 @=gateway.xyz.com  ALL  0.0.0.0
