Check out DONTCLICK.IT for a very cool concept site that shows an example of navigation without mouse clicks. One interesting implication is the biometric fingerprinting possibilities. One area of the site allows you to see the movements of previous visitors to the site. It seems possible to us that tracking the movements of a mouse, […]
Click-Free Web App And Mouse Movement Fingerprinting
HP and the Business Domain
I was thinking about HP and their decision to get out of the PC market and purchase Autonomy. It makes sense to me. HP can do well in the business information domain. Domain… information… There are three main domains for information: personal, business, and public. The Internet was primarily used as public after the burst […]
Using DJGPP and other UNIX-like tools to manage NT servers
What is it? DJGPP is a collection of UNIX-like tools for DOS/Windows that has been ported from the GNU project. For a better understanding of what we mean by UNIX-like, see gnu.org. We’ve found DJGPP indespensible for tweaking files for automated installs from the command prompt. With this version you can run the utilities from […]
Compiling Opensource programs on NT/95/98
Windows users are at a disadvantage in the open source environment becase they are not used to compiling programs. The idea of recompiling the NT kernel just simply doesn’t cross the mind of a typical MCSE. Programs are usually shipped precompiled. In the *nix world it is routine to download the source code for a […]
Creating an NT Server Test Lab Using VMware
One thing we do quite often here at netadmintools.com is install and reinstall NT Server and friends over and over again. This article describes how to setup, configure, backup to tape, and restore an NT Server installation on Vmware. We installed Vmware using the simple directions that came with the distribution, and then ran a […]
Using XP to Administer Linux with Cygwin
We loaded up a copy of Windows XP Professional today, and the first thing we needed to do was administer our Linux boxes. There are a lot of stand alone tools out there. For SSH, PuTTY works well. What is even better, though, is to use Cygwin. The Cygwin collection of utilities is very complete. […]
Xterm on Windows
We have written about Cygwin in past articles. This article will focus on getting Xterm to run on Windows. Xterm emulation works. Resize during a session? No problem. Unix style cut and pastes? Sure. The catch is you have to run X on your Windows box… heh, heh. First, install Cygwin, then copy the binaries […]
Authenticating Windows 2000/XP Clients With LDAP using pGina
One extremely cool programming project that you should check out is pGina. pGina replaces the authentication module on Windows 2000 and XP clients so that they can authenticate via SSL with an LDAP server. Further, pGina uses authentication plugins, so over time other methods can be used as interest determines them. The author was published […]
Running a GNU/Linux Distribution on Mac OS X using Bochs – Part 1
There are 3 parts to this article: Part1 – Part2 – Part3 We sometimes need a real GNU/Linux system to fiddle with, even when we are on our Mac. It is useful to test out configurations, etc. Bochs works well as an emulator. Slow, but it is free. What to install for the GNU/Linux system, […]
Running a GNU/Linux Distribution on Mac OS X using Bochs – Part 2
There are 3 parts to this article: Part1 – Part2 – Part3 DSL comes with Lilo, and that suits us fine. We need to remove grub and copy linux24 to /boot on the new partition. We didn’t need minirt24.gz, but weren’t sure. You may want to copy it over just in case: We want to […]
Running a GNU/Linux Distribution on Mac OS X using Bochs – Part 3
There are 3 parts to this article: Part1 – Part2 – Part3 Here is what the hardware is looking like on our boot from our hard disk image: This /etc/fstab file worked for us: The next boot went well: Here are the /etc/init.d srcripts that we removed to make booting tolerable: Now, these automagic scripts […]
Creating a Disk Image for Bochs
Bochs is an open source PC (x86) emulator that runs on a variety of platforms, including GNU/Linux and Mac OS X. One of the first things that you need to do to get started is to create a disk image. There is a utility that comes with Bochs, that does much of the work for […]
Migrating From VMware to Bochs
There is a utility that will allow you to mount your VMware vmdk images here: www.vmware.com/download/ws/ We used VMware-mount-5.0.0-13124.exe: C:\Program Files\VMware\VMware DiskMount Utility>vmware-mount w: s:\usr-2\d.vmdk C:\Program Files\VMware\VMware DiskMount Utility>dir w: Volume in drive W has no label. Volume Serial Number is 3344-0E04 Directory of W:\ 08/24/1996 11:11a 93,812 COMMAND.COM 04/07/2004 06:48a 0 CONFIG.SYS 04/05/2004 07:28a […]
Emulators for Mac OS X
We have always used Bochs in the past as our free emulator of choice. Bochs for OS X is very, very slow. Unreasonably so. There is another emulator project, though, QEMU that works much better. The speed seems five times faster on our particular O/S we boot in the emulator. It is actually usable without […]
Using a Full Desktop with VNC
We’ve run into problems remotely running some applications via X. Even when the app runs OK, it is quite sluggish. We also had trouble running in secondary X sessions, which is the default behavior of vncserver. Most apps acted just fine; however, some apps got confused about what desktop to use. We tried VNC, though, […]
A is for at
The at command is your willing and punctual servant for odd jobs, reminders and one-offs. A more footloose sibling of steadfast cron, at is used to schedule a task to run once at a given time. Then all is forgotten. The following examples and file paths are true for Red Hat Linux, and more or […]
B is for bash
Bash is a huge subject! The purpose of this article is demonstrate & explain some of the basics so you can write shell scripts and work at the command line more effectively. See also our article on Aliases and Functions in bash for ways to customize your environment. I recommend highly the bash man page!!! […]
C is for ch ch ch changes….
C is an extremely useful letter of the alphabet in Linux, especially when paired with an h. With these letters one can chown, chmod, chroot, and change lots of other things. One can even chkconfig. ***************************** chown – change ownership of a file. ***************************** Nothing too exciting to report here, but there are a couple […]
D is for df, du, dd
These three classic Unix utilities like to get their hands dirty with file systems. **************************************************** df – display disk space usage on mounted filesystems **************************************************** Every newbie sysadmin learns df right off the bat; it displays mounted file systems and the disk space usage on each. By default (in linux) it displays the statistics as […]
E is for Ext3fs Part 1
The ext3 filesystem now installs as the default file system in most Linux distributions. Essentially ext2 with journaling, ext3 retains the stability and robustness of ext2 while adding the much needed journal for high-availability. Part 1 of this article will discuss some filesystem basics and Part 2, some tips for working with the Linux native […]
