Verifying a Socket w/Perl

Using a lowercase hostname is typical but I got sloppy on a Windows 7 installation, after all Windows is case insensitive, and I used a mixed case hostname. It raised an interesting error when installing Oracle Database 11g Release 2.

Enterprise manager configuration failed due to the following error -

Failed to allocate port(s) in the specified range(s) for the following process(es): JMS

Linus on Instantiation and Armadaification
+0 Vote Up -1Vote Down

I feel a sense of pride when I think that I was involved in the development and maintenance of what was probably the first piece of software accepted into Debian which then had and still has direct up-stream support from Microsoft. The world is a better place for having Microsoft in it. The first operating system I ever ran on an 08086-based CPU was MS-DOS 2.x. I remember how thrilled I was when we got to see how my friend’s 80286 system ran BBS software that would cause a modem to dial a local system and display the application as if it were running on a …

The blog was down yesterday

The brief outage was due to a scheduled move of the servers to a separate rack and subnet dedicated to our work with the Center for Information Assurance & Cybersecurity (ciac) at the University of Washington Bothell (uwb), and

I am currently exercising the new (to us) equipment and hope to winnow the less than awesome equipment over the next quarter. I spent the last six months finding the best in breed of the surplussed DL385 and DL380 chassis we (work) were going to have recycled. The team and I were able to find enough equipment to bring up one of each with eight and six gigs of memory, respectively. These will make excellent hypervisors for provisioning embedded …

NIST::NVD::Store::SQLite3 1.00.00
+0 Vote Up -0Vote Down

It’s been released. Use this with NIST::NVD 1.00.00 and you will be able to perform immediate look-ups of CVE and CWE data given a CPE URN. For instance:

cjac@foxtrot:/usr/src/git/f5/NIST-NVD-Store-SQLite3$ perl Makefile.PL ; make ; make test ; cjac@foxtrot:/usr/src/git/f5/NIST-NVD-Store-SQLite3$ perl -MNIST::NVD::Query -MData::Dumper -e '
$q = NIST::NVD::Query->new(store    => q{SQLite3},database => q{t/data/nvdcve-2.0.db});
$cve_list = $q->cve_for_cpe( cpe => q{cpe:/a:microsoft:ie:7.0.5730.11} );
print Data::Dumper::Dumper { cve_list => $cve_list, first_cvss => $q->cve( cve_id => $cve_list->[0] …

NIST::NVD 1.00.00
+0 Vote Up -0Vote Down

I’m leaving myself some room for bug fixes. It works for us in house. I would love to help others to give it a try. especially those who could benefit from making nearly immediately answered queries to the NIST’s NVD database.

The code in this release cannot by itself track the feed from the feds in real time. The nvd entry loader needs a little bit of love in the area of record merging before this starts working. It’s on my TODO list.

I’m sorry for the outage of I’ll get that back up here shortly. In the meantime, feel free to grab it from this location while the CPAN indexes and processes my submission.

Interviewing tip..
+0 Vote Up -0Vote Down

I've been involved in a number of interviews over the last few weeks as a client has been loking for a MySQL DBA. When you are looking for position as a DBA in a large scale environement there are some very important things you have to know.

You absolutely must know a scripting language. In a smaller environment this often isn't necessary. You will live and die by this in a large environment. I asked every applicant one specific question..if you had to change a mysql server variable on a pool of 100 mysql servers how would you do this? It's easy when it's one,two or even a dozen servers. just log in, change the my.cnf and change it "on the …

NIST::NVD CWE development – follow along

I’m in the process of getting the tests passing for the 0.03 release of NIST::NVD::Store::SQLite3 wherein our hero imports the CWE data and cross-indexes it with CVEs and CPEs.

Follow along and suggest some patches. I’m developing on Debian Wheezy, but I would very much like input from devs on other platforms.;a=summary

I published an SQLite3 storage back-end to NIST::NVD on the CPAN. It’s pretty quick. About as fast as the DB_File one, but without the down side of being tied to DB_File. It shouldn’t be too difficult to re-factor this code to any DBI-based database. MariaDB anyone?

I know it works on Debian. The nightly CPAN test results should come back shortly and I’ll find out how well it works on other platforms.

Pluggable M3 (Monitis Monitor Manager) Framework

Who needs an introduction about M3? – Perhaps no one!
After gaining some reputation with M3, providing extra-easy integration of any monitor into Monitis it was time to take it to the next level.

Generally speaking, the work flow of M3 was described in detail in …

Learning to love the InnoDB Lock Monitor
+3 Vote Up -0Vote Down

A customer opened a support issue to ask about some help determining why they were seeing a lot of Lock Wait Timeouts. I asked them to enable the InnoDB Lock Monitor so that I could get a look at what was going on in their transactions and whether there might be some locks held longer than necessary.

The customer sent in a 184MB MySQL error log with 4773836 lines. I started looking through it, but I could tell I was going to need a better way to get a better overview of the file than what I'd be able to piece together trying to poke through it and look for individual lines. I started piping the file through a variety of UNIX tools to narrow down what I …
