SKOOR Engine Changelog

9.0.0

  • Upgrades to PostgreSQL 17
    • Needs skoor-repo.9.0.rpm
    • Perform a full dnf update, not only dnf update "eranger-*".
    • Run /opt/eranger/database-utils/bin/upgrade-postgresql AFTER update.
    • Since the Multicorn extension gets updated as well and because there is no upgrade path from 2.4 to 3.x, we remove and reinstall the extension. This causes all related foreign tables to be dropped as well. This affects related PostgreSQL views, but not data queries. The foreign tables can be created again using the init scripts of the affected components (e.g. init-foreign-tables.sh from the StableNet FDW component), PostgeSQL views referencing foreign tables should be dumped before performing the update and recreated after it.

8.1.7

  • Does not open ports 514/udp, 52998/tcp, 50001/tcp and 5432/tcp automatically upon SKOOR installation anymore. If some of those ports need to be opened (not recommended), this can be done using firewall-cmd --zone=public --add-port=<port>/tcp --permanent && firewall-cmd --reload Already opened ports are not closed automatically. We highly recommend closing such ports using the commands below:

    • Listens open ports firewall-cmd --list-all

    • Closes ports from above: firewall-cmd --zone=public --remove-port=514/udp --permanent

      firewall-cmd --zone=public --remove-port=52998/tcp --permanent

      firewall-cmd --zone=public --remove-port=50001/tcp --permanent

      firewall-cmd --zone=public --remove-port=5432/tcp --permanent

      firewall-cmd --reload
