Howto

Upgrade

To upgrade your existing SELKS 3 to SELKS 4 preview, please refer to SELKS-3.0-to-SELKS-4.0-upgrades wiki page.

It is recommended to follow the onscreen instructions and if needed answer “yes” to all changes. At the end of the upgrade you will be asked to enter the interface that you will use for IDS/sniffing. Please enter (eth0 for example) the interface name and reboot when the script is done.

Create your own ISO

To create your own SELKS 4 preview ISO (if your host OS is Jessie):

git clone https://github.com/StamusNetworks/SELKS.git
git checkout SELKS4-dev
./install-deps.sh
cd /usr/share/live/build/data/debian-cd/ && ln -s squeeze stretch
./build-debian-live.sh

It will take probably 30-40 min and you should end up with the SELKS.iso under the Stamus-Live-Build folder.

Once installed/upgraded
  • Please feel free to choose the IDS sniffing/listening interface either via the desktop icon Setup-IDS-Interface or via the cmd calling /opt/selks/Scripts/Setup/setup-selks-ids-interface.sh
  • Any further upgrades are done via a wrapper script located in /opt/selks/Scripts/Setup/selks-upgrade_stamus.sh
  • Recommended set up for SELKS 4.0RC1 is 2CPUs 5-6Gb RAM
  • If you need to reset/reload all the dashboards  – you can do like so
    • In Scirius on the top left corner drop down menu select System Settings
    • click on the Kibana tab
    • choose Reset SN dashboards
