Nodefactory based on FreeBSD-10
Scope
We intend to implement a number of changes/improvements:
- based on FreeBSD-10.1 (until release use 10-STABLE
- unbound replaces bind; recursive dns server on standard-node; authorative server for wleiden.net domain on two special servers in the network
- implement latest version of lvrouted (auto update default route)
- update captive portal to increase speed: use static html pages, write in C
- cleanup packages that are no longer required: nrpe, vim, bash-static, pftop, nmap, python-Jinja2, sixxs-aiccu, openvpn
- possibly replace thttpd (light version of apache? nginx?)
- bsnmp replaces net-snmp
- patch isc-dhcpd (#580.3) or use dnsmasq as dhcpd-server (?)
will keep
- ucspi-tcp-0.88_2 for redirect captive portal
A. Setup a FreeBSD host
Warning: 1) Make sure /usr is at least 5GB in size, as building images requires quite some space. 2) Make sure you install the 32bit i386 release of FreeBSD also when your system does support amd64, as cross compiling can give some nasty surprises.
Tip: use a separate hard disk, mounted on /usr/obj to speed up the compilation process.
Get yourself a fresh i386 freebsd host with ports and subversion installed as follows:
A.1. Run the basic CD installer
The procedure below has been tested with 10.0 (standard developer install - no ports -, e.g. with default partitioning will fit our needs). Installing FreeBSD is outside the scope of this document, take a look into the FreeBSD handbook Chapter 2 Installing FreeBSD if you do not know the details.
Please do mind that all commands below need to be executed as root, because of the many mounts and unmounts done in various phases. It maybe convenient to permit ssh root login (modify /etc/ssh/sshd_config accordingly).
Internet connection is required.
Set correct date/time, e.g: build# ntpdate 0.nl.pool.ntp.org
(You may also wish to add ntpd_enable="YES" to /etc/rc.conf)
A.2 Install Subversion and Ports
Subversion and root certificates are installed as a package:
build@ pkg install ca_root_nss build# pkg install subversion
Check out a copy of the ports tree (this will take a couple of minutes).
build# svn checkout https://svn0.eu.FreeBSD.org/ports/head /usr/ports
Tip: if for some reason this svn checkout doesn't work for you consider the use of portsnap:
build# portsnap fetch extract
A.3 set some useful variables
Alter the shell configuration file:/root/.cshrc:
Ensure ftp is set to passive mode, to avoid potential firewall issues: build# echo 'setenv FTP_PASSIVE_MODE YES' >> /root/.cshrc Set a default password for the images that you will produce build# echo 'setenv CFG_ROOT_PASSWORD DefaultPassword12!' >> /root/.cshrc Define your nanobsd (svn) working directory: NOTE: All commands at later stages will refer to this so you better get it right! build# echo 'setenv R /root/nanobsd' >> /root/.cshrc
Next load your file (or login again): build# source /root/.cshrc
A.4. update lvrouted port if necessary
Warning: Skip the following steps unless you want to update the current lvrouted version (12878) and know what you are doing:
Checkout latest version of lvrouted (i.e. beyond 12878):
build# svn checkout http://svn.wirelessleiden.nl/svn/node-config/other/lvrouted/trunk /usr/local/share/lvrouted
run the release.sh script to produce the tar 'release' file (lvrouted-.......tar.gz):
build# cd /usr/local/share/lvrouted/ build# tools/release.sh
Upload the lvrouted-12878.tar.gz to the webfolder.wirelessleiden.nl/lvrouted/ directory and
- update PORTVERSION in $R/ports/net/lvrouted/Makefile
- run 'sha256 lvrouted-......tar.gz' to determin the sha (secure hash) value
- modify the SHA256 en filesize in $R/ports/net/lvrouted/distinfo.
- commit $R/ports/net/lvrouted
A.5. OPTIONAL, every developer has his own preferences, e.g.
build# pkg install vim-lite build# pkg install sudo build# pkg install screen
Tip: screen can be a handy tool if you are working on a remote host.
With 'screen' you can open a virtual terminal, in which you can do everything like in the normal terminal. But you can detach it if you want to do other things in the main terminal and reattach it later. It even works after you quit your main terminal. Common screen commands: 1. Start a new terminal: # screen 2. Type CTRL+A and D to detach this new terminal 3. Reattach it: # screen -R
A.6. get latest sources
build# svn co svn://svn0.eu.FreeBSD.org/base/stable/10 /usr/src
B. Build environment
B.1 Download the environment from the Wireless Leiden svn repository
build# svn checkout https://svn.wirelessleiden.nl/svn/code/hybrid/branches/releng-10/nanobsd $R build# cd $R
If svn is not found: svn is in /usr/local/bin, alternatively log out and in, or use rehash in a csh shell to make it available.
B.2. Compile all required packages using
build# $R/tools/package-build.sh
This will take quite some time (on remote host use <screen>), depending on your hardware of course. Packages are created in /root/nanobsd/pkg/All:
build# ls $R/pkg/All bash-static-4.3.24.txz openvpn-2.3.4.txz ca_root_nss-3.16.3.txz p11-kit-0.20.3_1.txz curl-7.37.1_2.txz pcre-8.35.txz dnsmasq-2.71_1,1.txz pen-0.18.0.txz easy-rsa-2.2.0.m.txz perl5-5.16.3_11.txz fping-3.10.txz pftop-0.7_2.txz gettext-0.18.3.1_1.txz pkg-1.3.6.txz gmp-5.1.3_2.txz py27-Babel-1.3_2.txz gnutls-3.2.16_4.txz py27-Jinja2-2.7.3.txz iftop-0.17.txz py27-MarkupSafe-0.23.txz indexinfo-0.2.txz py27-pytz-2014.4,1.txz iperf-2.0.5.txz py27-setuptools27-5.5.1.txz isc-dhcp42-server-4.2.7.txz py27-yaml-3.11.txz libffi-3.0.13_1.txz python-2.7_2,2.txz libidn-1.28_1.txz python2-2_3.txz libtasn1-4.1.txz python27-2.7.8_4.txz lvrouted-12879.txz screen-4.2.1_3.txz lzo2-2.08.txz sixxs-aiccu-20070115_4.txz mtr-nox11-0.85_1.txz sudo-1.8.10.p3_1.txz nagios-plugins-2.0.3_2,1.txz thttpd-2.25b_5.txz net-snmp-5.7.2_16.txz tinyproxy-1.8.3_1,1.txz nettle-2.7.1.txz trousers-tddl-0.3.10_7.txz nmap-6.47.txz ucspi-tcp-0.88_2.txz nrpe-2.15_3.txz vim-lite-7.4.398.txz
B.3. Set your favorite root password to be used in the image
Note: you can skip this step if you are satisfied with the default password set in step A.3 above.
$ setenv CFG_ROOT_PASSWORD `dd if=/dev/random bs=10k count=10 |\ tr -cd '[a-zA-Z0-9]' | cut -c -15` $ echo $CFG_ROOT_PASSWORD
If you like a simple password, substitute the
`dd if=/dev/random bs=10k count=10 | tr -cd '[a-zA-Z0-9]' | cut -c -15`with your password.
B.4 Build nanobsd (make sure to prepare some coffee;-) ; use screen)
$ sh /usr/src/tools/tools/nanobsd/nanobsd.sh -c $R/cfg/nanobsd.wleiden
Note 1: Take a coffee of go for a hike, this normally takes 2 - 8 hours depending on the machine configuration. If you like to save some power use the script provided by Rick (http://rickvanderzwet.nl/svn/personal/misc/power-saver). This script is mainly used on a home server for building FreeBSD world and kernels. As soon it is done it can shutdown if not being used anymore. The system has Wake-On-Lan support and can thus be activated again from remote.
Note 2: even this little script got flags, check the output of
sh /usr/src/tools/tools/nanobsd/nanobsd.sh -h-b suppress builds (both kernel and world) -k suppress buildkernel -w suppress buildworld -c specify config file ...
Note 3: a safe alternative is the image-script available in $R/tools/ :
build# $R/tools/image buildThis script checks whether a kernel and/or world are already available and skips these steps. This may prevent lengthy, unnecessary builds ;-)
Note 4: The geometry of the cf card is defined in the nanobsd configuration file $R/cfg/nanobsd.wleiden The 'default' values are for a Peak 1 GB card. They also work on an Alix2D3 board with a 1 GB PCEngines 'blanc' cf card and 1 or 2 GB Transcend cf cards although those geometries are different. There are issues with Soekris boards, depending on BIOS version.
