Hi. I'm a Unix Administrator, mathematics enthusiast, and amateur philosopher. This is where I rant about that which upsets me, laugh about that which amuses me, and jabber about that which holds my interest most: Unix.

It escapes the dollar sign in its password or else it gets the "login denied" again

Fun case today. Customer complains that they cannot login to an Oracle instance.

I check the IP. It's wrong. Dear customer, please use the correct IP, which is $some_private_ip.

Customer then complains that they get an error that the service is unknown. I double check, they should be using "$dbname", not "$dbname\-db". I explain.

Customer then complains that they are getting a login denied error. I suspect there is something...

I'm a bit of a security nut. It's true...I'm a tad paranoid, and it shows in the design of my home network.

Given the paranoia, it's really only a matter of time before my over-arching power-Nazi stance on security steps on the toes of my other household members, namely my wife. She really lost it one day when unbound failed (well, it didn't *fail*, but it wasn't exactly working as *she* intended). I attempted to step her (an avid Windows power user with zero experience with the...

OpenBSD's W^X Policy

Posted 01-13-2015 at 10:22 PM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

OpenBSD has had userland "W^X" (Write XOR Execute, a policy in which memory pages can be marked writable OR executable, but never both at the same time. This policy defeats attacks that rely on an executable stack or other write-then-execute arrangements).

Now OpenBSD has applied W^X to the kernel (amd64 thus far) as well, along with ASLR and a few other improvements.

In a discussion on openbsd's tech@ mailing list, it was determined that ntpd-4.2.8 contained approximately 190k lines of code...a count that came up after the 8 vulnerabilities in ntpd were recently announced.

(DISCLAIMER: lines of code are difficult to count fairly, especially comparing one product to another, but this gives a rough "ballpark" idea of LOC).
