What is RCF (rc.firewall)? RCF (AKA rc.firewall) is an ipchains-based firewall with support for over 50 network services (including vtun, DHCP, NFS, SMB, napster, proxies, online games, etc.), masquerading, port forwarding, and IP accounting. All services are self-contained modules which can be prioritized easily in the ipchains stack. Protections include spoofing, stuffed routing/masqerading, DoS, smurf attacks, outgoing port scans, and many more.

ADB) Production or stable kernels have a well defined feature set, a low number of known bugs, and tried and proven drivers. They are released less frequently than the experimental kernels, but even so some "vintages" are considered better than others. GNU/Linux distributions are usually based on chosen stable kernel versions, not necessarily the latest production version.

ADB) These are intermediate pre-release versions of version f.g.hh. Note that usually i < 5, but e.g. 2.0.34prei was available with i = 1 to 16. Sometimes "pre" is replaced by the initials of the developer putting together the kernel revision, e.g. 2.1.105ac4 means the 4th intermediate release of kernel version 2.1.105 by Alan Cox.

RRR) Depending on your patch there are several ways to get it into the kernel. The first thing is to determine under which maintainer does your code fall into (look in the MAINTAINERS file). If your patch is only a small bugfix and you're sure that it is 'obviously correct', then by all means send it to the appropriate maintainer and post it to the list. If there is urgency to the bugfix (i.e.

REG) Originally, Linus Torvalds maintained the kernel. As the kernel has matured, he has delegated maintenance for older stable versions to others, while he continues development of the latest "bleeding edge" release. As of 27-MAY-2002, the following kernel versions are maintained by these people:

REG) See the Kernel HOWTO for some information. Also, there are people at http://www.kernelnewbies.org/ who are usually willing to help. William Stearns) The Buildkernel script walks you through an entire kernel build, including downloading the necessary files, patching the source, building the kernel and modules, installing the lot into lilo, and optionally building pcmcia-cs, cipe, and freeswan code for that kernel.

These files are OEM versions of Ontrack. They have got a big bug: an error occures when you want to rename a file. The IBM*.COM files nativly support the new partition type 0Fh (LBA). It's not recommended to use these files if you don't know what you do. The COMMAND.COM file seems to be okay, but I didn't notice any changes.

It seems that the specified internal interface is down. Make sure it's up and execute the script again. It seems that the specified external interface is down. Make sure it's up and execute the script again. The specified module cannot be found. They are usually located in /lib/modules/your_current_kernel_version/ipv4/ Make sure you compiled your kernel correctly (see chapter 4. How should I configure my kernel?).

Building a new kernel was originally pretty much a required step in a FreeBSD installation, but more recent releases have benefited from the introduction of a much friendlier kernel configuration tool. When at the FreeBSD boot prompt (boot:), use the -c flag and you will be dropped into a visual configuration screen which allows you to configure the kernel's settings for most common ISA cards.

ADB) Linux kernel versions are divided in two series: experimental (odd series e.g. 1.3.xx or 2.1.x) and production (even series e.g. 1.2.xx, 2.0.xx, 2.2.x, 2.4.x and so on). The experimental series are fast moving versions which are used to test new features, algorithms, device drivers, etc. By their own nature the experimental kernels may behave in unpredictable ways, so one may experience data losses, random machine lockups, etc.

ADB) The primary site for the Linux kernel (experimental and production) sources is hosted by Transmeta (the company Linus Torvalds used to work for) on a dedicated Web server at http://www.kernel.org/. This site is mirrored across the world, and has pointers to mirrors for each country. You can go directly to a mirror for your country by going to http://www.CODE.kernel.org/ where "CODE" is the appropriate country code.

REG) There are many places which provide various extra patches to the kernel for new features. One fairly good archive is available at: http://www.linuxhq.com/.

No. Many people mistaken palm oil for palm kernel oil. Palm kernel oil has very different chemical composition and physical characteristics compared to palm oil (see Figure 1). Both these oils come from the same fruit but they are uniquely different. Palm oil comes from the flesh or mesocarp of the fruit while palm kernel oil comes from the kernel or seed of the fruit. Palm oil and palm kernel oil have different impact on heart disease risk due to the different composition of fatty acids.

If you have a 2.2 or a 2.0 kernel, you can upgrade to 2.4 ;) Sorry but I don't support those kernels.

Believe me: Nothing. The driver runs completely in user space and therefore shouls not produce kernel panics. This seems to be an OS bug. Please write down the message (or take a photograph) and mail it to me along with a detailled description about what you did when you encountered this and your system configuration. I will try to find the cause and contact Apple to find a solution.

RCF doesn't support iptables yet. Not to worry, ipchains will be supported for quite some time in the 2.4 kernels. (Refer to netfilter.filewatcher.org/unreliable-guides/packet-filtering-HOWTO/index.html) RCF will be ported to iptables eventually, but since defining a firewall with iptables is a far more complex matter than with ipchains, don't expect a reliable version (of any firewall for that matter) to come out soon. To use RCF with a 2.4 kernel you need to compile support for ipchains.

VPShosting.net.au does not allow for any kernel modifications. You will be running a variant of Linux 2.6.x which is the latest stable Linux kernel.

A source RPM is available on the downloads page. This source rpm includes a patched version of the official kernel from kernel.org. The LinkGear kernel patch is included for reference. Alternatively, this patch can be downloaded directly and applied to the official linux kernel, see below for the necessary steps to retrieve the kernel and patch.

application kernel is a software module, core, or library, forming part of a complete terminal application architecture that is developed for exclusive support of the EMV debit/credit functions and application requirements. Since application kernels are functionally tested and approved by EMVCo as standalone components, they may be ported to other hardware platforms under certain conditions.

The basic design of QNX® is a micro kernel. Win95, NT, UNIX and OS/2 all have a "monolithic" design in which the core operating system code is very large. Generally speaking, system level functions like hardware drivers must be part of the kernel to run. This is for, among other reasons, processor "supervisor" privileges are usually limited to kernel code for protection.

The latest kernel sources are available from ftp.netbsd.org or one of the mirrors in the directory /pub/NetBSD/NetBSD-current/src/sys/ . Check out the NetBSD/mac68k Meta-FAQ for more information on following current sources.

Any kernel should do. The real time stuff may not exist in older kernels (1.2.13 and before), but just compile without it. Note that more and more drivers in newer kernels carry out their own PnP activity, so some ISA PnP cards may not even require isapnptools to configure, though isapnptools can still be useful for diagnosing things. You must be root to run isapnp and pnpdump because the program requires direct access to the IO ports. If you compiled the program using gcc2.8.

A kernel module is a piece of code placed in the kernel address space. This is similar to shared libraries. The module can contain data and code as you wish. Being in shared memory the module and it's code can be accessed by any thread in kernel mode. When the module is loaded a special initialization function will be called and should quickly return success or failure. Before the module is unloaded an optional cleanup function is called, this must do whatever cleanup needs to be done.

Yes you can do that. Most modules don't need to create any kernel threads. If you are writing a driver and think you need a kernel thread you could easily be wrong.

Unfortunately there is no simple debug technique. If you open your iPod case it may be possible to use the JTAG interface or hook into one of the serial ports but I've never opened my iPod so you'll have to look elsewhere for assistance there. One of the serial ports for the 1/2G iPod is connected to the headphone jack, at least as an input, it could be possible to use that but I've never tried. Progress has been made on using the 3rd Gen's remote connector as a Serial Port.
