Top talkers, listeners reports available

There is a new entry on the Network Engineering statistics web page listing the top 50 consumers of Internet bandwidth in both incoming and outgoing directions.


There is an explanation of the numbers and a pair of links, one each to the top 50 consumers of incoming and outgoing bandwidth, respectively.

There is, unfortunately, no archive on the web page yet. Each day's table simply overwrites the previous day's report.

The job to produce the tables takes over 8 hours to run, so the previous day's stats don't appear until late in the afternoon. Nothing to be done about that yet. The run time and memory requirements of the reporting program are limiting us to top talkers and listeners right now, so no, we can't add source and destination ports to the report.

DNS updates for registered hosts

For quite a long time, users with newly-registered computers had to wait up to six hours for those new registrations to be reflected in the campus DNS servers. The update process was overly conservative, to avoid losing any data, and took too long to be run more frequently.

The old process also left a short window when a particular hostname could be unresolvable -- it removed all old hostnames, then added them back in batches. There was a period between a hostname's removal and its readdition that the hostname would be unknown by the campus name servers.

The update process was recently rewritten -- it is now much faster and does not remove hosts whose IP address and hostname remain the same. Since it's faster, it can be run every hour, so users have to wait no more than 60 minutes to see a newly-registered host in the DNS.

Legal Delay

So let me get this straight. Tom Delay says that only a Republican may preside over his trial, since a Democrat who has contributed money to Democratic organizations in the past is too partisan.

A fiercely partisan Republican indicted in part for illegal campaign contributions to Republican candidates can't be tried in front of a judge who's contributed legally to Democrats? How ironic.

We should consider ourselves fortunate that there's a Republican judge available to sort this all out.

Prepare for some good old-fashioned Texas mudslinging.

Chronology of a disaster

[Thanks to my friend Kevin Smith for this recitation of events.]

January 2001

Bush appoints Joe Allbaugh, a crony from Texas, as head of
FEMA. Allbaugh has no previous experience in disaster

April 2001

Budget Director Mitch Daniels announces the Bush
administration's goal of privatizing much of FEMA's work.
In May, Allbaugh confirms that FEMA will be downsized: "Many
are concerned that federal disaster assistance may have
evolved into both an oversized entitlement program...." he
said. "Expectations of when the federal government should
be involved and the degree of involvement may have ballooned
beyond what is an appropriate level."


FEMA designates a major hurricane hitting New Orleans as one
of the three "likeliest, most catastrophic disasters facing
this country."

December 2002

After less than two years at FEMA, Allbaugh announces he is
leaving to start up a consulting firm that advises companies
seeking to do business in Iraq. He is succeeded by his
deputy, Michael Brown, who, like Allbaugh, has no previous
experience in disaster management.

March 2003

FEMA is downgraded from a cabinet level position and folded
into the Department of Homeland Security. Its mission is
refocused on fighting acts of terrorism.


Under its new organization chart within DHS, FEMA's
preparation and planning functions are reassigned to a new
Office of Preparedness and Response. FEMA will henceforth
focus only on response and recovery.

Summer 2004

FEMA denies Louisiana's pre-disaster mitigation funding
requests. Says Jefferson Parish flood zone manager Tom
Rodrigue: "You would think we would get maximum
consideration....This is what the grant program called for.
We were more than qualified for it."

June 2004

The Army Corps of Engineers budget for levee construction in
New Orleans is slashed. Jefferson Parish emergency
management chiefs Walter Maestri comments: "It appears that
the money has been moved in the president's budget to handle
homeland security and the war in Iraq, and I suppose that's
the price we pay."

June 2005: Funding for the New Orleans district of the U.S.
Army Corps of Engineers is cut by a record $71.2 million.
One of the hardest-hit areas is the Southeast Louisiana
Urban Flood Control Project, which was created after the May
1995 flood to improve drainage in Jefferson, Orleans and St.
Tammany parishes.

August 2005

While New Orleans is undergoing a slow motion catastrophe,
Bush mugs for the cameras, cuts a cake for John McCain,
plays the guitar for Mark Wills, delivers an address about
V-J day, and continues with his vacation. When he finally
gets around to acknowledging the scope of the unfolding
disaster, he delivers only a photo op on Air Force One and a
flat, defensive, laundry list speech in the Rose Garden.


Remember -- it's not the blog, it's whether you have something interesting to say. Maybe I will, maybe I won't. You decide.

One thing is guaranteed: updates will be irregular.
