I’m getting ready to deploy a pair of Server 2008 Active Directory servers to replace a couple of old 2003 boxes. In preparing those servers, I installed the remote agent for Microsoft Data Protection Manager before I installed the ADDS role and promoting the new AD servers. That turned out to be a mistake. After promoting the AD servers, the DPM agent service (DPMRA) stopped running and would not start again.
I’ve been playing with this Chrome OS notebook today since it’s seeming surprisingly stable given the problems I had with it last night. I’m beginning to wonder if the battery charge indicator was lying to me. Anyway, besides Chrome, the app I most use on my laptop is ssh. I use it to get into my server at home and to log into work if there are problems that I can fix from home.
Google is coming out with a new operating system they call Chrome OS. It’s new and shiny and I thought it would be fun to try out but don’t have the free cash the throw into buying a new device with it installed. (Not that there are any out at the moment.) Anyway, a month or so back I signed up for the Google Chrome OS Pilot Program. The program is designed to help Google find new guinea pigs to try Chrome OS and give Google feedback on how it works.
I switched to Fedora 14 on my laptop a few weeks back. It’s been working great but there’s no package for the Password Gorilla which I use to keep track of passwords. Fortunately, installing from source is easy. yum install tk itcl Now that the prereqs are installed, we can grab the source. I checked out the code from the git repository but you can get the tarball. Since gorilla is a TCL app, there’s nothing to compile.
While trying to get System Center Configuration Manager to install a package on a new server, I rediscovered why I hate working in Windows and why I like PowerShell. I wanted to check the end of a series of log files to see what was going on. Unfortunately, Windows has no obvious analog to the unix tail command. Fortunately, my friend Jon Angliss had most of a solution. Get-Content <filename> -wait That’s close to what I want but not quite.
I recently set up a IPv6 tunnel with Hurricane Electric’s free tunnel broker. Once your tunnel is created, HE provides instructions for setting the tunnel up on your system. Easy peasy. I decided that I wanted to setup a tunnel on my laptop. That’s a little tougher since my laptop will be getting a dynamic IP from the various wireless networks I connect to. Even more fun, since most wifi networks I connect to in hotels and airports, etc.
One of my problems at work is that I always want my mail and chat windows visible while I’m working. Sure, I could set up multiple windows and hope they stay where I put them. But it’s a pain to set those windows up every time. Since I’m using mutt for email and irssi for chat and instant messaging with bitlbee, I thought, why not use screen to organize the windows and, as a special bonus, I can pull up my session from anywhere over ssh.
There are a number of ways of using RT from within emacs. A quick google search will find them. Here’s what I use. RT First, you’ll need to snag a copy of the rt perl script from /opt/rt3/bin/ or from the source package. This can go almost anywhere on your local system but I put it in $HOME/bin/. Make sure you make it executable. Next, create $HOME/.rtrc. This will contain the information rt needs to access your RT install.
I spent a couple of days a while back trying to figure out why I was seeing bizarre bridge and network errors in my KVM host’s syslog and a VM that only two of three NICs worked at a time. Turns out that there is a very simple fix for both problems. First, let’s start with the KVM host network configuration. Here’s the basic config for a host with two NICs.
One of my criteria for choosing a virtualization platform is that it had to run Windows and Linux guests. Linux, of course, works out of the box on most VM hosts. Windows is a whole other story. The good news is that Windows Server 2003 and Server 2008 work just fine on KVM. There are, however, a few weird things that I’ve noticed so I thought I’d share some of them with you today.
