Today I discovered Ketchup, a little command-line tool to manage your Linux kernel sources. If you’re one of the weirdos, who is still compiling his kernel manually for whatever reason (like I do), I can only recommend it. Ketchup nicely eases up the entire process of checking for updates and applying them to your system. [...]

This is one the essential and important task. Many time we upgrade our kernel and some precompiled drivers won’t work with Linux. Especially if you have weird hardware; then vendor may send you driver code aka C files to compile. Or even you can write your own Linux kernel driver. Compiling kernel driver is easy. [...]

/etc/defaultrouter is the configuration file for default router under Solaris os. The /etc/defaultrouter file can contain the IP addresses or hostnames of one or more default routers, with each entry on its own line.

Under FreeBSD operating system you need to use the kldload utility to load file.ko into the kernel using the kernel linker. You can find all loadable kernel drivers in in /boot/kernel or /boot/modules/ directory. Some modules (pf, ipfw, ipf, etc.) may be automatically loaded at boot time when the corresponding /etc/rc.conf statement is used. Modules [...]

As a system admin, I need to use additional hard drives for to provide more storage space or to separate system data from user data. This procedure, adding physical block devices to virtualized guests, describes how to add a hard drive on the host to a virtualized guest using VMWare software running Linux as guest. [...]
