X2Go Session Broker Demo Environment Setup

Purpose of this document

This document takes you through the steps required to set up a simple X2Go Session Broker demo environment, consisting of a test client (x2goclient1.x2go.example.com) and the following servers:

DO NOT EVER USE THIS IN A PRODUCTION ENVIRONMENT! YOU WILL HURT YOURSELF VERY BADLY IF YOU IGNORE THIS WARNING!

These instructions violate almost every “best practice”/standard there is!

They are meant to get an X2Go Session Broker demo enviroment set up, fast.

Nothing more, nothing less.

This setup has the following shortcomings:

  • Massive lack of security:
    • Unencrypted LDAP connections
    • All passwords - users, database admin, root, are set to the value “start”
    • SSH keyfile login is only enforced for the root account
  • No redundancy for critical components
    • Only a single LDAP server, no replication
    • Only a single NFS server
    • Only a single Postgres server
    • Only a single X2Go Session Broker server
    • No RAID1/RAID5/RAID6 setup for any system
  • No backup
  • No monitoring/alerting
  • No easy manageability/heavy abuse of LDAP:
    • LDAP settings are converted from local settings on the “ldap1” server
    • what ends up in LDAP this way is not something you want to work with in a production environment
    • it will be faster to set up a new LDAP server with the proper settings for your production environment than to base your server on this demo and trying to “clean up” afterwards
    • Also, no user-friendly tool to manage LDAP settings is installed by default.

Setting up the systems

Preseeding - Manual Steps

These are the steps you have to perform manually:

Each entry below contains a hint regarding the minimum requirements for the individual system. If you're using virtual machines, and are low on disk space, feel free to assign sparse files/growing disk images. The systems don't really need that much space right away, but if you assign smaller sizes, the installer might become confused and partition the virtual disk in unexpected ways.
If you click on the name of a preseed file, like “preseed_ldap1” below, you will be offered to download it - that's easier than copy-pasting each file.

ldap1.x2go.example.com

preseed_ldap1
# There are two sets of parameters you can use as the append line:
# The minimum required is:
# hostname=ldap1 domain=x2go.example.com
# url=http://192.168.0.224/preseed_ldap1
# (all in one line, and without the leading "#" marks)
# If you only use these, you will have to answer a few questions
# - mainly regarding country, keyboard and locale - interactively.
# For a fully automated installation, add these parameters 
# *in addition to the ones listed above*
# (again, all in one line, and without the leading "#" marks):
# priority=critical netcfg/use_dhcp=true netcfg/choose_interface=eth0
