INSTALLATION NOTES

some notes taken when rebuilding distrait.pl.sophia.inria.fr

general

  • date : 2023 Nov 7
  • fedora : 38
  • major changes from faraday:
    • the network config is made in nmcli natively - and not in ifcfg files
    • as a result dnsmasq MUST NOT be setup as a standalone app
    • but must be configured as a NetworkManager plugin
    • see https://docs.fedoraproject.org/en-US/fedora-server/administration/dnsmasq/ for more details
    • at this point the testbed config still goes in /etc/dnsmasq.d/testbed.conf but is symlinked from /etc/NetworkManager/dnsmasq.d/

base install

  • used a fedora38-server vanilla distro
  • usual bootstrap with ssh keys
  • cd /; git init; echo '*' > .gitignore; git add -f .gitignore; git commit -m"gitignore"
  • did network config manually with nmcli MAKE SURE TO HAVE THE .nmconection file in mode 600
  • nmcli con up control

installed rpms

  • dnf update
  • dnf install emacs-nox
  • dnf-install iptables iptables-services
  • rpm -e firewalld
  • dnf install python python3-pip
  • dnf install -y git
  • turn off selinux
  • reboot

images

  • for testing rhubarbe load the best is ubuntu-16.04-v3-stamped.ndz because it's only 600 Mb
  • later on I went for getting the images built within 300 days.. why not 
    root@faraday
rsync -aq -partial $(find /var/lib/rhubarbe-images -maxdepth 1 -type f -mtime -300) [email protected]:/var/lib/rhubarbe-images/

post install

  • clone r2lab-embedded and diana

  • install diana bash

  • get-gitprompt

  • pip install rhubarbe

  • apply r2lab-misc/inventory to create config

  • symlink /etc/profile.d/ faraday.sh and r2labutils.sh

  • installed frisbee binaries from r2lab-misc/ (manually)

  • dnf install syslinux syslinux-nonlinux syslinux-tftpboot

  • restore /tftpboot from faraday

  • in rhubarbe.conf.local:

    [nodes]
load_default_timeout = 900
save_default_timeout = 900
[networking]
bandwidth.distrait = 200

  • install r2lab-nightly timer from r2lab-embedded

    systemctl start r2lab-nightly.timer
systemctl stop r2lab-nightly.timer

  • installed miniconda for setting up a dev env (see make preplab in rhubarbe)

  • to be continued... probably need to tweak this code for the cases where there's no inventory-pdus.yaml but the nodes do get turned off, so..

historical section - OLDY (2017)

context

the context for the contents of this file was:

  • 9 March 2017
  • fedora25
  • based on reinstall of r0lab/preplab (known as etourdi.pl.sophia.inria.fr at the time)
  • was done after the facts so may not be 100% accurate
  • previous install of bemol was with ubuntu

base

  • 3 network interfaces

    • internet
    • reboot on 192.168.1.100
    • control on 192.168.3.100
    • renamed with udev rules

  • turned OFF selinux f...

  • turned off firewalld

    • would ruin DHCP traffic
    • need to use iptables instead
    • or to better understand firewalld

images

  • restored /var/lib/rhubarbe-images from bemol's backup

dnsmasq

  • dnf install dnsmasq

  • systemctl enable dnsmasq

  • systemctl start dnsmasq

  • /etc/dnsmasq.conf

  • plus of course the outcome of running make preplab in r2lab/inventory

conf-dir=/etc/dnsmasq.d,.rpmnew,.rpmsave,.rpmorig


log-facility=/var/log/dnsmasqfit.log

dhcp-authoritative
enable-tftp

syslinux/tftpboot

  • dnf install syslinux-tftpboot

frisbeed

netcat

on ubuntu

  • we run this
nc -d -l 192.168.3.100 10001
  • where -d means 'do not read from stdin'

on fedora

  • the nmap-ncat package has a binary
  • where -d expects an argument that expresses a delay

config

so we now have a new config flag [frisbee] netcat_style = ubuntu

that needs to be set to fedora in /etc/rhubarbe/rhubarbe.conf.local
