Creating DOS boot image to flash BIOS or firmware

Gavin Burns, from I Do Linux has a useful tip that you can use to upgrade of flash your servers BIOS and/or firmware. These utils are often DOS floppy images. Besides not having a floppy anymore these days, getting the server to boot a floppy image can present challenges too. Dell's DRAC often eludes me because the boot order won't choose the floppy (unless I hit F11 to get the boot menu, of course).

From the article Create DOS Boot Disk for CD or GRUB you'll learn to get the DOS floppy image and create a bootable ISO from it. You can burn the ISO to CD or use the boot image to add a GRUB menu option. Handy!

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.

Dell Linux - OMSA Hardware Monitoring

Just getting started using Dell's OpenManage Server Administrator (OMSA) on our Oracle Linux platform. There are some confusing instructions going around so it's not immediately clear what to do, hence my blogging here. :) There is a site on Dell - Hardware Monitoring , as well as a wiki with instruction on how to setup their OMSA tooling using yum or up2date. [update]My first update for their instructions: be sure your server has Internet access, as most servers will use a proxy or so. use export http_proxy=http://yourproxy.example.com:port to configure it just for the session, and setup up2date to use an HTTP proxy by editing the settings in /etc/sysconfig/rhn/up2date .
