Creating a custom boot and splash image

While researching ways to create a custom boot image, so I can provision new systems automatically with a CD or a mounted ISO image, I also learned how to create a custom splash.lss image.

Most web pages out there instruct you to install ancient, obscure giftoppm tools - which you may not have or know how to get. I found out Irfanview (for Windows) easily lets you open and edit JPG or GIF images, rework them, add logos and text and save the result as a PPM file.
Then just scp the .ppm file to Linux and use the ppmtolss16 tool (obtained through 'yum install syslinux') to convert the PPM file to LSS. Build the custom ISO image and you're done!

Tuning the nscd name cache daemon

I've been playing a bit with the nscd now and want to share some tips related to tuning the nscd.conf file. To see how the DNS cache is doing, use nscd -g. nscd configuration: 0 server debug level 26m 57s server runtime 5 current number of threads 32 maximum number of threads 0 number of times clients had to wait yes paranoia mode enabled 3600 restart internal passwd cache: no cache is enabled [other zero output removed] group cache: no cache is enabled [other zero output removed] hosts cache: yes cache is enabled yes cache is persistent yes cache is shared 211 suggested size <==== 216064 total data pool size 1144 used data pool size 3600 seconds time to live for positive entries <==== 20 seconds time to live for negative entries

Preventing PuTTY timeouts

Just found a great tip to prevent timeouts of PuTTY sessions. I'm fine with timeouts by the host, but in our case the firewall kills sessions after 30 minutes of inactivity... When using PuTTY to ssh to your Linux/Unix servers, be sure to use the feature to send NULL packets to prevent a timeout. I've set it to once every 900 seconds, i.e. 15 minutes... See screenshot on the right.

Setting up SR-IOV in RHEL6 on PowerEdge servers

Dell Community : "RHEL 6 provides SR-IOV functionality on supported hardware which provides near native performance for virtualized guests. Single-Root I/O Virtualization (SR-IOV) specification, introduced by PCI-SIG details how a single PCIe device can be shared between various virtualization guests. Devices capable of SR-IOV functionality support multiple virtual functions on top of the physical function. Virtual Function is enabled in hardware as a light weight PCIe function. Operating System cannot discover this function as it does not respond to the PCI bus scan and requires support in the host’s driver. As in PCIe pass-through, a Virtual function of a SR-IOV capable card can be directly assigned to the guest operating system. A virtual function driver running in the guest manages this device."
