We share our printers out from cups using samba. It was working great until a recent update broke the drivers from the windows/samba side. I decided to redo the configuration and use the cups driver for everything. Only problem was that after doing that I couldn't add the third (optional) tray to our HP 2420DN. After reading a little about PPD and using cupsaddsmb to install the cups driver for windows clients, I came up with this hack job that appears to be working.

We've had this dream for some time of having a display that we can control from our desktops but mounted in the hallway. The idea would be to use the sign in place of post-it notes or some other sort of messageboard arrangement. We've tried the Kodak EX811 in the past with limited success, we used mediatomb to control the kodak, but wheneverthe wireless network had problems or the kodak got confused, it would just go to a blank screen, hardly useful.

allmybase.com has a good article on how to get skype working properly on F11. If your sound keeps crapping out or your video doesn't look quite right, check out his fix.

I've finally posted the initial version of my "howto setup an install server" book at narrabilis.com. I start with installing tftp, dhcp and named to allow machines to pxebook. Then go on to configure kickstart to have machines install themselves. Then use kickstart to configure puppet and have puppet (with augeas) configure the machines. I briefly cover func, using func to quickly make changes. It's still a work in progress and I welcome any comments. Hopefully it will be useful to someone, somewhere. It's still lacking a good title.

This is a one liner...but some people here didn't know what to do with the zip file that MPC comes packaged as. [root@server] unzip StandaloneMulti-PlatformClient*zip Archive: Standalon... extract mpc-install.MPC_*jar [root@server] java -jar mpc-installer*jar The multi-platform client is a nice java gui to access the DominionKX line of IP KVM switches. I find it works better than accessing the switch through firefox.

In this example I was trying to serve files up from samba and lighttpd at the same time. I made the type for the files samba_share_t. After that, lighttpd couldn't access the files. I needed to make an selinux module to fix the problem. Here are the steps to create the module quickly.

I use puppet to keep my machines in sync with each other. Our default configuration has haldaemon and messagebus (dbus) off. I ran into a problem when I tried to create a new vm and there was no option to use the shared phyical device (the bridge)

A talk I gave on using puppet. I cover installation and initial configuration. It is a talk not a tutorial though, when I get a chance I'll post a short tutorial...

A talk I gave on using kvm. I have a video on doing a live migration at the end of it (you tube). I use virsh to perform the migration and watch the movement with virt-manager.

using kvm

On our kvm hypervisor we have several vm's using fibre channel for storage. The hypervisor has to see all the devices, but each device has it's own lvm so when the hypervisor boots, it tries to read all of them.
