( Modified from , for HTB support for linux kernels 2.4.19 and lesser)
1.1 Installation of the Linux kernel
The default Linux kernel location is folder /usr/src/linux-2.4.18
(Specifically use kernel 2.4.18. Kernels 2.4.19, 2.4.20, 2.4.21 were tried and were found to give “kernel panic” on boot.)
– A copy of compressed kernel (linux-2.4.18.tar.bz2) has to be copied
to folder /usr/src/. This is the default kernel location, and the
intended start point for all further operations.
– This directory may contain a symbolic link linux to the old kernel
folder. If so this has to be removed.
– Decompress the kernel by:
~ /usr/src> tar -xvjf linux-2.4.19.tar.bz2
Now create the architecture dependant links:
~ make xconfig (or make menuconfig or make oldconfig)
and exit immediately
1.2 Software List
– Components of the RSVP-TE software can be downloaded separately from
site http://ds_mpls.atlantis.rug.ac.be. These comprise:
KERNEL_2.4.19_MPLS172.patch, iptables-1.2.4-0.2-dscp.tgz, DSMPLS+IP.patch, iproute2-current.tar.gz and rsvpd.0.70-rc2.tgz.
2. Uncompress iproute2 package into ~rsvp/
3. HTB patch
Uncompress htb patch (from http://luxik.cdi.cz/~devik/qos/htb/) into /usr/src and then:
>patch –p1 < ../htb_*.diff
4. MPLS Patch
– Move KERNEL_2.4.19_MPLS172.patch into the folder /usr/src and
type the command:
~ /usr/src/linux-2.4.19> patch -p1 < ../KERNEL_2.4.19_MPLS172.patch
~ /usr/src/linux-2.4.19> patch -p0 < ../DSMPLS+IP.patch
5.Uncompress iptables into ~rsvp/
6.Change the makefile for the Kernel path
7. go to ~rsvp/iptables/ and do “make patch-o-matic”
8. then “make” then “make install”
9. Go back to Linux kernel /usr/src/linux-2.4.18 and do: make menuconfig
Compile the kernel with at least the following networking options
(enable “Prompt for development and/or incomplete code/drivers”)
1)Network packet filtering
2) TCP/IP networking
1.IP: policy routing
1.IP: use netfilter MARK value as routing key
3) MPLS support
4) IP: Netfilter Configuration
1.IP tables support (enable all suboptions unless you know what you are
doing, make sure “DSCP match” and “MPLS target” support is available.
5) QoS and/or fair queuing
(enable all suboptions unless you know what you are doing)
6) Network device options
10. the compile: make dep && make clean && make bzImage && make modules && make modules_install
11. In the boot directory: cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.18
12. cp System.map /boot/System.map-2.4.18
13. Now change the grub and reboot
14. Go to iproute2 directory, and turn diffserv on inside config file: Diffserv=y
15. Change the makefile for the kernel path
16. Then: patch –p1 < ../IPROUTE2-rsvpd0.60
17. cp /usr/src/linux/tc/q_htb.c ~rsvp/iproute2/tc/
18. make clean; make
19. cp ip/ip /sbin; cp tc/tc /usr/local/bin
20. Installation of rsvp-te
~mv linux linux.old
~ln -s /usr/src/linux/include/linux linux
#ls -ld /usr/include/linux
lrwxrwxrwx 1 root root 28 Nov 21 18:14 /usr/include/linux-> /usr/src/linux-2.4.19/include/linux
Note: this method seems to be necessary for RedHat systems Open a file manager window and show subfolders of /usr/src/linux/include .
Right-click on subfolder linux and choose copy. Then, select folder /usr/include, right-click and paste, choosing option ‘Overwrite All’, when requested. This is because RedHat7.1 doesn’t refresh that folder with new kernel data at reboot. For the same reason, in folder /usr/include a symbolic link should be created to folder /usr/src/linux/include/asm-i386.
– Put the downloaded file rsvpd.0.70-rc2.tgz in /home and execute the
~ /home> tar -zxvf rsvpd.0.70-rc2.tgz
This will produce a folder /rsvpd containing all the requested
subfolders and files.
~ /home/rsvp>cd rsvpd
– Now you can compile:
~ /home/rsvp/rsvpd>make clean
The daemon is now compiled and can be found in folder /home/rsvp/rsvpd/rsvpd. Tools are in folder /home/rsvp/rsvpd/labeltest.
Copy the mplsadm executable from /home/rsvp/rsvpd/labeltest to /usr/local/bin.
~ cp labeltest/mplsadm /usr/local/bin
Before running the daemon some configuration files must be set:
~ /home/rsvp/rsvpd>vim label.conf
Check that interfaces name correspond to active devices and change where it is necessary. Save to /etc/label.conf.
~ /home/rsvp/rsvpd>edit ds_config
Check interface names in line
