Services.exe running at 100% CPU and using 100s of MB of memory – Windows XP SP3

Friday, July 24th, 2009

I came across an interesting one in the last few days. This system was a Windows XP system with current updates – SP3, IE 8…. and among other things there was a complaint of very sluggish behavior. I updated the antimalware software installed and ran scans. Malware Bytes antimalware actually found and removed two suspect [...]

Windows lost administrator password rundown….

Friday, January 19th, 2007

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 [...]

Linux Permissions Headache

Wednesday, October 18th, 2006

Yikes, what an evening….. it started innocently enough in the afternoon. I have an old Mandrake 10.0 server that I was upgrading clamav on (recent security update). While I was at it, I was reviewing the anti-spam setup to see if I could get any better success with filtering junk mail. spamassassin has had an [...]

The great firewall of China

Thursday, June 29th, 2006

The great firewall of China may be just an illusion in technical terms. This article describes the details of how things work…. Basically when “banned content” is detected, both ends of the connection are sent a flood of tcp reset packets. Which (if both sides are designed to pay attention to) means that the two [...]

NTFS cloning

Wednesday, June 28th, 2006

Sometimes drives just go bad. Surprise. One recent fresh install of Windows XP had started having real stability problems. On running a chkdsk and looking at the event viewer, it was fairly clear that 16KB of bad sectors and the disk problems had likely been the problem (lots of disk and atapi errors in the [...]

The D-Link DWL-800AP+ as a wireless repeater to extend wireless range – Part 6

Monday, January 2nd, 2006

Ok, so here’s the synopsis… I’ve spent the last few articles setting up a D-link DWL-800AP+ as a repeater for a linksys WAP11 (v. 1.1) As of the end of the last entry I had a bit of a problem with WEP but that seems to have been resolved now and here I am to [...]

The D-Link DWL-800AP+ as a wireless repeater to extend wireless range – Part 2

Monday, January 2nd, 2006

For starters, I hooked the D-link DWL-800AP+ up and connected it through a crossover cable to my usb network card. That way I could access it exclusively on one adapter and look online for information with the other adapter, which came in quite handy. The first thing I found was that by default the dwl-800ap+ [...]

Global White Space Reset (CSS/html)

Monday, December 12th, 2005

This may not be useful to many people, but I thought it was interesting. If you do web design and use css you’ll probably like this… I found this post at about a neat way to “reset” the padding and margin css information which can help for designing sites to display the same when [...]

Bad week for Cisco, security headaches

Wednesday, August 3rd, 2005

For starters, there was this advisory last week in response to a planned talk at a hacker convention on the possibility of a cisco router ipv6 exploit. The advisory detailed a LOCAL exploit and not the remote exploit that the talk was centered around. There was legal action against the speaker and materials detailing it [...]
