Kernel Compile - Ernest G. Wilson II's FreeBSD Pages

Compile the Kernel on FreeBSD 7

Prerequisites:

FreeBSD (Base + Autoconf, Automake, Bash and GCC)

Building and Installing a Custom Kernel – Adapted from the FreeBSD Handbook

# Part I. Customize your make.conf (Optional)
vi /etc/make.conf
COPTFLAGS= -O2 -pipe -funroll-loops -ffast-math BOOTWAIT=0 PERL_VER=5.8.8 PERL_VERSION=5.8.8

# Part II. Customize your kernel
# Make sure you have a copy of the kernel source code! Let's find out:
# Change to the Kernel configuration file directory
cd /usr/src/sys/i386/conf
# If you don't have that directory with code, go get it using sysinstall tool:
# sysinstall --> configure --> Distributions --> src --> sys

# Make a copy of the GENERIC kernel file and edit the copy (Typically copy it to your computer's name)
cd /usr/src/sys/i386/conf
cp GENERIC NMS

# Learn about the hardware found on the machine you are about to compile (see what was detected etc.)
dmesg | more

# Edit your new configuration file (adds, removes, comment stuff out etc.)
# Comment (#) out all unwanted options (refer to kernel config as your guide) example (then save and exit):
# Here are some options you will need (and want) built-in to your kernel - Add these:
vi /usr/src/sys/i386/conf/NMS
# SMP Optional Dual CPU # ident SMP-GENERIC # options SMP # Symmetric MultiProcessor Kernel # Increases the system memory limits - does not restrict you to only 512 uers maxusers 512 # IPSec VPN options IPSEC #IP security options IPSEC_ESP #IP security (crypto; define w/ IPSEC) options IPSEC_DEBUG #debug for IP security # IPFilter Firewall options IPFILTER options IPFILTER_LOG # options IPFILTER_DEFAULT_BLOCK # PF Firewall device pf device pflog device pfsync options IPFIREWALL options IPFIREWALL_FORWARD options IPFIREWALL_VERBOSE options IPFIREWALL_VERBOSE_LIMIT=10 #options IPFIREWALL_DEFAULT_TO_ACCEPT # Will accept everything without rules file # To hide firewall from traceroute options IPSTEALTH # Add some protection capabilities for the web services options ACCEPT_FILTER_DATA options ACCEPT_FILTER_HTTP # Incease network performance options DEVICE_POLLING options HZ=1000 # Don't forget to edit: /etc/sysctl.conf add kern.polling.enable=1

# Add this line to the end of /etc/sysctl.conf
vi /etc/sysctl.conf
kern.polling.enable=1 net.inet.icmp.icmplim=5000

# Optional information and examples:
#Here is an example Kernel config from a Dell 670
Setup: 3.8Ghz Zeon, 2GB RAM, 2 SATA Drives, Intel Ethernet
Disabled via BIOS: Sound, Serial, Parallel, USB, Firewire and SCSI

# Prepare your Kernel by using the config command:
/usr/sbin/config NMS

# Change to the newly created config directory and set the dependencies:
cd ../compile/NMS
make cleandepend
make depend

# Compile the new Kernel
make

# Install the new Kernel only if you compiled without errors:
make install

# WARNING: DO NOT REBOOT YET!
# You need to complete the firewall settings since your new kernel has a firewall!
