FIxing Win10 Taskbar Context for Putty

I recently upgraded Putty on my Windows 10 machine to the latest 64 bit version. After doing so, I was disconcerted to discover that I could no longer right-click its taskbar icon to  see a list of sites I had connected to previously. This was reminiscent of when I first installed Win10 and had the… Read More »

Network Booting with DNSMASQ in Proxy Mode

In this project, I will show you how to network boot an Arch Linux ISO image with DNSMASQ set up in proxy DHCP mode. The approach taken here should readily generalize to the ISO images of other distributions. If you understand what’s being done here, adapting to another distribution should not be too difficult. I’m indebted to… Read More »

Amazon Web Services S3 via Command Line

Amazon Web Services (AWS) has a nice Command Line Interface, allowing script or command line access to quite a wide range of capabilities. I recently attempted to use this with the Simple Storage Service (S3), but was frustrated with a repeated error message in response to a simple directory request on a bucket. jeff@mars:~$aws s3… Read More »

Fixing VSFTPD login problem

I recently set up a new Ubuntu 12.04 server, and as part of the setup installed vsftp. I used an identical setup to a similar server, but for some reason, I kept getting an authentication error attempting to login as a local user. After a lot of troubleshooting, I finally isolated the problem to the… Read More »

Antenna Patterns at NX6T

I recently used N6BV’s HFTA antenna and terrain modeling software to analyze the antenna setup at NX6T, in particular to assess the benefit of replacing both antennas on the 40′ tower (a 2 element 40M yagi and a 3 element SteppIR) with a single KT-36XA, with 5 elements of 15 and 20, and 6 on 10. The terrain surrounding… Read More »

America’s Six Foot Tiki

Dear Selected Members of the U.S. House of Representatives, I used to think of myself as a fiscal conservative, I guess because I thought among other things I ought to pay the bills for things I’ve bought. Even stuff that I kinda wish I hadn’t, like that awesome 6 foot tall tiki statue I got… Read More »

Faster IPSET loading

IPSETs are a very efficient way to manage a large list of IP addresses for your iptables firewall. Rather than have an individual rule for each and every address or network that needs to be dropped or rejected, with ipsets you can have a single iptables rule that tests an entire list of addresses. The rule… Read More »

Sneaky IE10 Default Change

[Rant] It’s no secret that Microsoft has been aggressively pushing Internet Explorer 10 (IE10) on their Windows 7 customers, for example by changing the Importance rating in Windows Update from the usual “Recommended” to “Important”. It’s a little beyond me why all the other Internet Explorer version upgrades were “Recommended”, but suddenly IE10 is “Important” losartan potassium… Read More »

Botnet Attack

As has been extensively publicized elsewhere, a very large scale botnet has been organized to attack sites using WordPress. This site has the dubious honor to have been included this last weekend. The attack attempts to log in to the site using the user name “admin” or a number of variants on that name, then… Read More »
