Yesterday, of course, Microsoft released it’s monthly patches. I found the Windows update site to be painfully slow (and in some cases unresponsive.) It wasn’t quite a huge update day by recent standards, but here’s the summary…. Incidents.org has a nice chart showing the two re-released patches (one is actually re-re-released…) They are MS06-040 (server service patch – critical) and MS06-042 (IE 6 patch). Both of those vulnerabilities addressed are well known and could be actively exploited. The “first release” updates from this month affect Microsoft Queue System MS06-052 which is the most important of the releases….

Multihead PC
More than once I’ve wished for a second (or third) set of keyboard/mouse/video for my main desktop. Linux is a true multiuser operating system which means that it’s capable of hosting multiple graphical logins at the same time. For MOST things, a single, modern CPU is more than adequate to deal with this (memory is usually the limitation, but 1 GB ought to be enough.) So, I think all of this was prompted by a blurb about hubster which looks like it’s just a VGA-usb adapter. The company that makes it though bill it as a thin client of sorts. So, they’re essentially thinking thin-client over usb as opposed to thin-client over ethernet…

Audio on Linux weekend…
For most people here in the US, this last weekend was known as Labor Day weekend, for me though… it was more like Audio on Linux weekend. I’ve mentioned before that I use my computer for most EVERYTHING and that’s not far off…. I have watched movies on the PC, I’ve recorded multitrack audio, captured tv shows to disc, and of course, work…. database server, digitial photos/editing, test web sites, word documents, test various hardware, etc. etc. test software, etc…. vmware…. oh the list could keep going and going and going…. Well, sometimes it seems that optimizing the machine for one thing comes at the expense of another. Since I had to swap out the system board on the main machine (massively failing probably due to overheating…. multiple pci slots had failed, etc….) I hadn’t had a chance to see why some things didn’t work the way I used to….

Linspire’s Click n run is now free
First, Linspire released the freely available “freespire” release of their operating system (based on debian linux). Now, users will no longer have to pay an annual subscription for the click n run service. That’s now available for free as well. There is a writeup here. Previously the annual subscription fees were $20/$50 per year depending on service level. This does not mean all software through cnr is free, there is commercial software available there for a fee. I know that not long ago there was some talk about opening up cnr (click n run) to other distributions, possibly starting with debian based distros such as ubuntu.

Sendmail DoS vulnerability
I’ve got to admit, I hadn’t caught the notice of this until it was at incidents.org. I don’t currently administer sendmail on any machines, but…. Sendmail released version 8.13.8 on August 9th to address several issues (including a DoS vulnerability). It was possible for a specially crafted email to trigger the problem.

Converting pdf to tif (tiff) images
One of the things I was looking into this morning was the possiblity of converting a pdf into a tiff image. Many character recognition programs (and some music recognition software) uses tiff as one of the formats that it can recognize from. I have a number of things in PDF format that I wanted to test out by converting to tif. There MUST be a way….. yes there is (several I suppose).. In linux though the answer is ghostscript.

Flashplayer 9 on linux
Macromedia Flash player 9 running on linux? Impossible? No… many things that seem impossible, well… aren’t This morning there’s a good writeup at how-to-forge about installing flash player 9 on linux. It involves wine and the how-to is specific to Ubuntu. However, the first two steps (sudo apt-get install wine and sudo apt-get install msttcorefonts) are the only ones that are ubuntu specific. For your given distribution, install according to your distro (urpmi/etc.)

Using screen to connect multiple users to a shell session
I NEVER knew you could use screen for this…. Let multiple users connect to the same Console (command shell/bash shell) session simultaneously. I’ve looked at screen before. It’s a great *nix utility that’s available for most linux distributions. The primary use I’ve seen for it is to be able to have a shell open, and use screen to be able to disconnect and reconnect to a session. Let’s say you have software compiling, you can use screen to get it started from one location and then re-connect to your screen session from another machine. Think…. VNC for the command line. Well, much like VNC it’s possible for multiple users to view and use the session.

Good sarc monitoring tip
Sarc is still in their month of security tips per day and todays is another good one. Todays tip is about monitoring machines, particularly those that “defend” your network. (Mail antivirus scanners/ proxy fitlers/scanners/etc.) The core of the advice is to not just ping – that only tells you if the system exists and is online – it doesn’t tell if things are working. They suggest scripting tests (antivirus scanner can be tested via the EICAR test signature for instance.) They note that doesn’t tell if the av scanner is updated (I prefer a crontab output of the days updates – looks like there were around 9 clamav signature updates yesterday.

But it’s brand new, how could it have so many updates?
This morning I was doing a fresh install of Windows XP SP2 into a Virtual Machine. So far, things are fine I went through windowsupdate and found 3 updates the first time, then rebooted and hit windowsupdate again to see 55 updates available. A lot of times when I set up a new pc for somebody they wonder why I want to check windows update multiple times. They’ll usually say something along the lines “but it’s brand new there shouldn’t be any updates.” Well, this install was from a SP2 disk and there have been a large number of updates since that was released. Many manufacturers use fairly sophisticated techniques to roll out the default install images they use, but it’s still very possible that your machine will have several updates waiting for it when you get it.
