X2Go Session Broker Demo Environment Setup

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:

• ldap1.x2go.example.com - an LDAP server for centralized authentication
• nfs1.x2go.example.com - an NFS server to have central home directories
• pg1.x2go.example.com - a postgres server for the X2Go session database
• x2gobroker1.x2go.example.com - an X2Go Broker Server, because that's what this demo is all about
• x2goserver1.x2go.example.com - an X2Go Server, so the broker has a server it can direct clients to
• x2goserver2.x2go.example.com - another X2Go Server, for loadbalancing

<note warning>

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.

</note>

• These installations use the Debian preseed mechanism.
  • Thus, obviously, you will require a Debian ISO image.
  • We used the Debian 8.7.1, i386, netinst iso image - however, any Debian 8.x iso image of the i386 or amd64 variety should do.
  • Preseed files can be included into a custom iso image, but for beginners, this may seem rather complicated - That's why we suggest using a web server to store them instead.
  • If you don't have Apache/Lighttpd, or any other web server installed, you can spawn a temporary one using python (you need to be root to run it on the default “web” port 80):

    cd /directory/where/you/keep/the/preseed_files && python -m SimpleHTTPServer 80

• Please review the content of each preseed-file. You will have to change the IP addresses, for example.
• If you have control over your DHCP server, we strongly suggest assigning fixed IPs to the MAC addresses of the machines you use - however, if you can't do that:
  • change each preseed file from DHCP to static IPs
  • edit the list in preseed_ldap1 so names and IPs match again
• You should set up the systems in the order that they are listed here.
• Each system will power down once the installation is complete. DO NOT power any one of them up until ALL of them are completely installed and shut down!
• Once installed, power them up in exactly the same sequence - and WAIT until bootup is complete before powering up the next!

These are the steps you have to perform manually:

• Boot the ISO. It will beep at you, and the option “Install” will be highlighted.
• Hit the TAB key (the key to the left ← of the “Q” key on most keyboards), and enter

   auto url=http://your-web-server/preseed_namegoeshere hostname=namegoeshere domain=x2go.example.com

  behind the part that says

  --- quiet

• You can either choose to confirm this by pressing the ENTER key, or add further options as listed in each preseed file's comment header.
• If you choose not to add further options, a few questions will be asked interactively, namely, the ones you can see in these screenshots:

<note tip>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.</note> <note tip>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.</note>

• Minimum RAM required: 256MB
• Minimum disk space required: 4 GB
• Also required: any supported eth0 network interface

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*
