Since there’s been quite a bit of flux the last couple of days I thought I’d try to “reset” the situation and give a general overview of where we stand now with regards to the recent WMF zero-day exploit. 1st there is a vulnerability in the way Windows renders WMF (Windows MetaFile) image files that […]

So after installing the php-pcre package, I restart httpd and reload the mythweb page and find another error message. Very similar to the first, but slightly different. “Fatal error: Call to undefined function session_name() in /var/www/html/mythweb/includes/init.php on line 48” (At least we’ve made it to line 48…) Anyway, yes… there’s a php-session package and no […]

After the Mandriva 2006 upgrade I’ve still been looking to find if there is anything ‘not quite right’…. anyway, I’ve run into an issue with mythweb. Mythweb is a web-based interface for the mythtv backend. It basically let’s you browse listings, schedule recordings, see what’s scheduled, etc. For me it’s kind of like checking one […]

After the Hamachi article I wanted to do a series on OpenVPN. I’ve used it before, but not since the 1.x days…. it’s now at version 2.0.5 and has quite a bit more flexibility. When I first used it, it was pretty much a point-to-point vpn solution. You could set up routing to see the […]

So, I’ve spent a bit of time talking about flightgear. Here are a couple extra resources that I want to “bookmark” here. There is a Good unofficial how-to here. (Mostly linux flightgear oriented. Also, the flightgear scenery is available here. The link is to a grid covered world map. Clicking on a grid quadrant downloads […]

I don’t know if kcron deserves a seperate entry for scheduling tasks under linux. Cron is what I typed on last time and it’s the daemon that controls scheduled tasks. The method for scheduling tasks that I went through last time is for the command line. Like many things in linux, there are other ways […]

So, when I did the laptop upgrade I formated the root partition which means that working mythtv frontend was erased and it had to be set up from scratch. I had been running version 0.16 of mythtv on all the systems, but finding rpms for that older version looked challenging, so…. I went ahead with […]

This should probably go in the Windows tech support category too… but, as I’ve talked about before I’ve spent a good amount of time using different linux livecd’s. I’ve even made a few livecd’s of my own with Mandrake (now mandriva) linux, using the mklivecd scripts. One of the nice things about a livecd is […]

This is really the same zero-day wmf vulnerability, but there is a twist. It’s been found that Lotus Notes v. 6.x and up are vulnerable to the Windows Meta File (WMF) exploit that’s making the rounds. Probably not surprising given that there are reports of many vectors of attack, not JUST the web browser. What […]

Windows has scheduled tasks which most people are only halfway aware of. Linux has very powerful scheduling capabilities coming from it’s unix heritage. cron is the daemon that deals with scheduled tasks under most linux distributions. There are a couple ways that you can schedule cron tasks. The first is from the command line.    […]
