Guitarlynn's Notepad Page

This page is a little strangle in the regards that there is no exact purpose to it. Over the years, on the many projects I've worked on, there are always little bits of information that I need. I need them often enough to be incovenienced by doing a web search for the information, but not often enough to retain the majority of it in my small, small mind. To keep this information handy, I have several notebooks and roughly 5,000 sticky notes with bits and pieces of this within 30 feet of me to find when I need it. I finally decided that several piles of various and incomplete notes isn't really efficient, so I am going to start compiling it in a text file so I can always find it within a couple of keystrokes and maybe even run off a neat printed set of pages. A good friend, Sean Walberg (of Brainbuzz and Cramsession fame), were debating whether web-publishing our application cheat sheets would benefit the general public In an after thought several days later, I decided that maybe my disjointed mess of notes may help some of you out there, so enjoy!!!!

write output to take directory as input
use the -J option for Joilet compatibility (M$ Windows)

*KERNEL COMPILING
Download or fine source tree in /usr/local/src or /usr/src typically.
Typically, if more than one source tree is present, they will be labeled
with the kernel version (ie... linux-2.2.19, linux-2.4.5) and the "linux"
directory is a link to the last compiled kernel. If this is so, you will
want to remove the link and make a new one to the source tree you will use.

cd /linux
make mrproper && make [config, menuconfig, xconfig, oldconfig]
make dep && make bzImage
make modules && make modules_install

Copy/link necessary files [bzImage, system.map] to correct place [/boot, /].
Update your boot loader [lilo, grub]. If your loader is lilo, you must then
re-run lilo (/sbin/lilo) to update it before rebooting, or else boot will fail.

*HELPFUL NETWORKING COMMANDS
