Check the current config of a Qlogic HBA easily by looking under proc. I was stumped on one system for a few minutes because I couldnt get to the .conf file or modinfo. All I really wanted to check at the time was that the driver version loaded on each host was the same. Then I was going to find SAN surfer to find more info… I guess you could get most of this info from dmesg | grep qla, or modinfo qla2xip or whatever.
No matter what flavor of linux distribution you’re using, the default grub bootloader background image is probably pretty generic. Or, maybe you just want to personalize it. Since your system isn’t booted very far, your toolset is rather limited, so there are strict requirements for the image.
With one exception, that is: Linux, which is right next door, and which is not a business at all. It’s a bunch of RVs, yurts, tepees, and geodesic domes set up in a field and organized by consensus. The people who live there are making tanks. These are not old-fashioned, cast-iron Soviet tanks; these are more like the M1 tanks of the U.S. Army, made of space-age materials and jammed with sophisticated technology from one end to the other.
How to install Qingy on Fedora. This will work on Fedora 8, Fedora 9, or Fedora 10. It’s all the same, so this will apply to all Fedora versions with directfb and directfb-devel in the repository. If you don’t find them in the repos, just build them from source too.
Use cryptsetup to setup dm-crypt managed device-mapper mappings. This method will allow you to use an encrypted mapping to transparently read and write encrypted data so that you and your applications don’t even need to worry about handling any encryption at all; it will just work, trust me. If you need to save data that’s already on the device, then copy it somewhere else, encrypt the drive, and copy it all back after encrypting.
Here’s my notes from trimming a little off the top of an apache server. This was just a quick chop at the default install. I haven’t looked at how the webapps are used or how many connections or the length of time per connection or anything… I’ll go back later and tweak how many threads and processes are started and used.
Here’s yet another good reason to think about breaking free from your mental slavery to microsoft. The same ones who had 4 xp desks in a perpetually broken state, even with AV and limited accounts, haven’t broken a default linux install yet.
