+***** PLANETLAB BUILD (within a slice) *****
+These instruction can be used by PlanetLab developers to compile the dummynet module
+on a node. To install the module on the node users need root access in root context.
+PlanetLab users that want to use the dummynet package should ask to PlanetLab support
+for nodes with dummynet emulation capabilities.
+
+ Follow the instructions below. You can just cut&paste
+
+ # install the various tools if not available
+ sudo yum -y install subversion rpm-build rpm-devel m4 redhat-rpm-config make gcc
+ # new build installation requires the gnupg package
+ sudo yum -y install gnupg
+
+ # create and move to a work directory
+ mkdir -p test
+ # extract a planetlab distribution to directory XYZ
+ (cd test; svn co http://svn.planet-lab.org/svn/build/trunk XYZ)
+ # copy the planetlab/*mk files here, overriding existing ones
+ cp planetlab/*mk test/XYZ
+ # download the specfiles and do some patching.
+ # Results are into SPEC/ (takes 5 minutes)
+ (cd test/XYZ; make stage1=true PLDISTRO=planetlab )
+ # Building the slice code is fast, the root code takes longer
+ # as it needs to rebuild the whole kernel
+ (cd test/XYZ; sudo make ipfwslice ipfwroot)
+
+ The kernel dependency phase is a bit time consuming, but does not
+ need to be redone if we are changing the ipfw sources only.
+ To clean up the code do
+ (cd test/XYZ; sudo make ipfwroot-clean ipfwslice-clean)
+ then after you have updated the repository again
+ (cd test/XYZ; sudo make ipfwslice ipfwroot)
+
+--- other, instructions (to be verified) ---
+
+To build a kernel module for the PlanetLab distribution you need a build system.
+For an up-to-date and detailed information on how to build a local myplc installation,
+a local mirror, a PlanetLab test system see[1]
+
+To create a build system you need to do the following steps:
+
+ 1. install CentOS 5, detailed information[2]
+
+ 1.A download the image from the main site[3] for example:
+
+ wget http://mi.mirror.garr.it/mirrors/CentOS/5.4/isos/i386/CentOS-5.4-i386-netinstall.iso
+
+ 1.B Add the repository
+
+ cat >> /etc/yum.repos.d/dhozac-vserver.repo <<EOF
+ [dhozac-vserver]
+name=Linux-VServer related packages for CentOS $releasever - $basearch
+baseurl=http://rpm.hozac.com/dhozac/centos/$releasever/vserver/$basearch
+gpgkey=http://rpm.hozac.com/conf/keys/RPM-DHOZAC-GPG-KEY
+EOF
+
+ 1.C Update, install and config the system
+
+ yum update yum
+ yum install kernel
+ yum install util-vserver{,-core,-lib,-sysv,-build}
+ yum install vim
+ yum install subversion
+ /etc/init.d/vprocunhide start
+ chkconfig vservers-default on
+
+ 2. create a vserver
+
+ 2.A Checkout the planetlab build
+
+ cd
+ svn co http://svn.planet-lab.org/svn/build/trunk svn-build
+
+ 2.B Search for a working RPM distribution in:
+
+ http://build.onelab.eu/onelab/
+ # good distribution ends in .ok, bad in .ko
+ # in this example we used the following:
+ http://build.onelab.eu/onelab/2008.03.02--onelab-f8-linux32/RPMS/
+
+ 2.C Creating a vserver
+
+ cd ~/svn-build
+ ./vtest-init-vserver.sh -f f8 -d onelab -p linux32 mybuild \
+ http://build.onelab.eu/onelab/2008.03.02--onelab-f8-linux32/RPMS/ \
+ -- --interface eth0:138.96.255.221 --hostname vnode01.inria.fr &> mybuild.log&
+
+ 3. create the build
+
+ 3.A Enter on the vserver, and create the build
+
+ vserver mybuild enter
+ cd \
+ svn co http://svn.planet-lab.org/svn/build/trunk build
+
+ 4. build
+
+ 4.A build[4]
+ cd /build
+
+ # full cleanup
+ make distclean
+
+ # the compilation is composed by several steps,
+ # make help for more information
+ # the first for the onelab compilation will download
+ # the SPEC file from the repository specified in
+ # onelab-tags.mk
+ make stage1=true PLDISTRO=onelab
+
+ # to download and build a module, for example ipfw:
+ make ipfw
+
+ # to do local changes
+ cd /build/CODEBASE
+ rm -rf ipfw
+ # download the ipfw sources and extract it into ./ipfw
+ # by svn
+ svn+ssh://onelab2.iet.unipi.it/home/svn/ports-luigi/dummynet-branches/ipfw_mod ./ipfw
+ # from web
+ wget http://info.iet.unipi.it/~luigi/dummynet/ipfw_mod-latest.tgz
+ tar xvzf ipfw_mod-latest.tgz
+
+ # start the compilation
+ rm -rf SOURCES/ipfw*
+ rm -rf BUILD/ipfw-0.1/
+ rm -rf SRPMS/ipfw*
+ rm -rf RPMS/i386/ipfw*
+ make ipfw
+
+ 5. download and install sources into a node
+
+ 5.A Copy RPMS into the node and install it:
+ # exit from the root context
+ exit
+ scp /vserver/mybuild/build/RPMS/i386/ipfw-* root@node.iet.unipi.it:
+ ssh root@node.iet.unipi.it
+ rpm -e ipfw
+ rpm -ivh ./ipfw-0-9...TAB
+ modprobe ipfw_mod
+
+ # the ipfw package should be installed
+ ipfw show
