Well… there was a news story a few days back about a pilot that had seen a strange orange light in the night sky near Chicago I think and claimed that the light was “not of this world”. It was later found out that it was likely a military flare (suspended by a parachute.) (Reportedly those flares put out 2 million candlepower..) Then LAST night on the local news there was a mention of people calling in reporting a green light in the sky. Today it’s all over the local news….

Building Deb packages from source….
Openvpn has been one of the tools of choice this week, so as I was tinkering on my ubuntu boxen…. I thought why don’t I install openvpn there as well for a little broader testing. So, I did, but was a bit disappointed to see that the version was not the most current. (Yes, they may have merged changes from the current version and left the version number at 2.0.6, but 2.0.9 is out and easy to build an rpm from source….. so….) I’ve compiled from source before, I’ve built RPM’s on Mandrake/Mandriva, but never a deb package.

Blacklists and rejecting mail with Sendmail
A long time ago I had found how easy it was to reject messages outright with Postfix that came from non-existent domains. You know… junk from asdflkjuasdlfkjh@imadethisupmyselfanditsnotregisteredanywhere.com
Well, since the mailserver at THIS site runs sendmail I wanted to fix sendmail the same as my home server. My home server is postfix based and uses fetchmail to pull from the website. Since I had the rules set to reject non-existent domains at home it would essentially strand messages in the account here at the website which would then need to be cleaned out manually.

iScsi and AoE with linux
A few days ago I had reason to investigate iscsi and AoE (ata over ethernet). Both are protocols for sharing a physical drive over the network at the block level. Let me put it in context first. Traditional network file shares have been done like this…. Computer A has a large drive, it’s formatted and available to Computer A and then THAT computer shares it out to computers B-zzzzzzz. iscsi and AoE basically share the bare drive and then computer B can attach to the drive format and make use of it as it’s own. Realistically I see the greatest advantage with this is adding storage to a server.

Windows lost administrator password rundown….
I’ve done one or two mentions in the past of ways to recover/reset lost windows passwords and thought it was probably time for another “brain dump/web research dump” of things that I’ve run across. This is not just for lost administrator passwords, but could apply to a lost user account password as well. (I’ve found that the mileage varies on the system. NT/2000/XP/2003 are not the only variations, there seem to be variations related to certain Windows updates/etc.) I should also put a disclaimer here that this information is not so you can break into someone else’s windows installation (without their permission), at the very least that’s a privacy violation and at the worst, against the law and unethical. What this is for is a guide to someone that has accidentally locked themself out of their windows install (or in some cases where someone ELSE has locked you out of your own pc.) In other words – don’t use this to crack.

VMware guest unable to access USB devices
I ran into this some time back and found the solution a few months later and was reminded today to document it here…. The situation is this… Linux host for VMWare server, the guest machine has usb support and in vmware, you can go to VM, Removable devices and in spite of the fact you have usb devices on the system, nothing is listed as available to use in the VM. Well, it seems this is not an isolated problem. First you need to be sure the usb device is not in use by the host system. But, there’s something else that you need. VMWare uses usbfs to keep track of usb devices and a few distributions ( Ubuntu Linux 6.06 SUSE Linux 10.1, SUSE Enterprise Linux Server 10, Mandriva Linux 2006, SLES9 SP3 64 bit) don’t enable it by default. ( mount -t usbfs none /proc/bus/usb ) should do the trick (as root) or you could set it in fstab usbfs /proc/bus/usb usbfs auto 0 0 (and now I’m thinking I may have already posted this once…. )

Live filesystem “capture” into a virtual disk image
ah… the joys of *nix utilities…. I’ve just successfully tested a “capture” of a live, running system into a virtual disk image. No, I don’t mean that I booted up with an imaging utility. I took a live, booted and logged in system and imaged the primary hard drive that it was living on, into a file on another machine. (Yeah, I know, there are probably a few people reading this and saying they’ve done that and most people that would need to do this already know how…. sorry I missed the memo.) Not too long ago, VMWare released a tool to do something like this (that tool is for windows…) This should work on any platform that supports dd and netcat (although I’m not sure if piping output from one program to another works with a dos command shell – maybe cygwin would be a good environment to accomplish this with.) Anyway… here are the details.

Google sign in’s out of order?
Is it just me or does it seem like about half of google sign in pages are out of order. (GMail seems ok) Adwords, Analytics, and Adsense all refuse to bring up the login box. (Main page for adwords and analytics loads, but the iframe that houses the login doesn’t.) It’s about 11:20AM EST now and this has been the case for the last hour or two. I haven’t seen any mention yet on official google blogs. (Calendar seems unresponsive for me right now too.)
Ok – I think it may have been just me, maybe leaving firefox open for 5 days at a time with 29 tabs causes funky things like that to happen. *(Tested on the same machine with another browser and the login came up, si I killed and restarted firefox and all is well.)

Time, value, ROI, Google and this site…. Googlebummed
This is a fairly significant “state of this site” type post and well… if you’re a usual visitor you might want to read/skim this one. It’s been about 15 months or so since the last big redesign of this site and as some long time lurkers may know, the updates were FEW and far between before moving to WordPress and this new layout. I mean, a year or so between updates was not uncommon. In the last year+ I’ve had a few spans where a month or so has gone by without posting, but in many cases I’ve been posting multiple (in other cases MANY MANY) posts in a single day.

Scanning over the network, or sharing a scanner on a network
I remember the question from long ago, we had just shared a printer across a windows network and…. wait for it…. “oh, well could I share my scanner too?” On windows the typical answer was NO, at least not unless there was a driver from the scanner manufacturer that supported it, but on linux the answer is an unqualified YES as long as the scanner is supported under linux (so many are..) Using SANE (which is the linux scanner driver backend) you can share out scanners across a network and tips.linux.com has an article on just that topic. I’ve set it up before on my network and it was relatively easy to do and VERY convenient. At that time, I don’t recall a good functional windows client for the SANE driver, but it may have matured a bit by now (last I looked into it was 3-4 years ago.)
