Sean’s Obsessions

A couple of links over at Linux Security caught my eye: A paper on how to attack LDAP based web forms. SQL injection attacks are old school now, but I’d never thought to apply it to LDAP queries. A cool use of Net::Pcap — write a daemon that promiscuously listens for a door knock, and [...]

A coworker sent me a link to RFC 1375, Suggestion for New Classes of IP Addresses, where a few new series of address space are broken out to handle /30′s and such. Compare this to CIDR, where we finally treat IP addresses as a 32 bit integer and move completely classless. What would the Internet [...]

$699 for a uniprocessor licence? No way. Sean

Even though I live in the socialist haven of Canada, I’m a strong believer in the free market. If it is true that SCO has a right to charge licencing fees on Linux, then the SCOX market capitalization should include both the value of SCO and the “value” of Linux. Today, the market cap is [...]

Still a work in progress, but I’ve joined the BlogRoll. Took a bit of work to get the BlogRoll plugin going, though. As it turns out the line $$html .= “<li><a href=’”.$site->{htmlUrl}.”‘>”.$site->{title}.”</a></li>\n”; should really have been $$html .= “<li><a href=’”.$site->{url}.”‘>”.$site->{title}.”</a></li>\n”; (Note that the url tag changed). Special thanks to the Data::Dumper module for helping me [...]

“Solution” is a strong word, but what can we do to reduce spam? Craig from Securely Speaking asked if using a public list of open relays as input to a firewall ACL was a good idea? I think not, but what is? One of the problems with reducing spam is determining the identity of the [...]

Pretty painless… Not so sure how much I like this Bluecurve, but hey, this is Linux, I can change it if I want.

Tony’s latest post has me wondering about that world of online Linux content. My newsletter was cancelled by Cramsession three months ago, and now Tony’s. I’m no longer aware of any Linux newsletters that provide solid information and tutorials. Most of the ones that I’ve seen (and have, for the most part, unsubscribed from) are [...]

After deciding not to fill out the surveys to keep my Red Hat Network subscription active, I decided “What the hell?” and did it. Oh well.

Take a peek at this article for more information on how the scheduler works, and the improvements coming in 2.6. Even if you’re not a programmer, it’s an interesting bit of information to know. Here is an article on encrypted file systems in both NT and Linux. It has actual implementation details, so if you [...]
