Open from host row Actions in the Servers page.

Actions In This Menu

• View Details: opens host details drawer.
• Restart Host: queues host reboot flow.
• Configure Auto-Restart: opens restart schedule modal.
• Update Workshop Item: triggers workshop update on this host.
• Install/Uninstall QLFilter: depends on current QLFilter state.
• Delete / Remove: removes host from management (or destroys cloud host).

What QLFilter Is

QLFilter is a host-level anti-DDoS filter. It uses eBPF/XDP to drop reflection garbage (DNS, SSDP, and similar noise) at the network driver level before it ever reaches QLDS. One installation covers all instances on the host.

For a full explanation: QLFilter

Operationally:

• Use Install QLFilter on new production hosts.
• Use Uninstall QLFilter only when you intentionally want it removed.

QLFilter Behavior In Menu

The QLFilter action changes based on current QLFilter status:

• not_installed, error, unknown -> Install QLFilter
• active, inactive -> Uninstall QLFilter
• installing, uninstalling -> action shows busy state and is locked

While QLFilter is installing/uninstalling, other host management actions are also blocked.

Update Workshop Item: Practical Use

1. Open Update Workshop Item from host actions.
2. Enter numeric Workshop Item ID.
3. Optionally pick running instances for automatic restart after update.
4. Submit and monitor instance status.
