1-9: Review of thenetstatcommand output.
The captured output ofsudo netstat -tulnpprovides a clear snapshot of active server sockets. The repeated entries forsystemd-resolveon port 53 appear as expected (possibly reflecting both IPv4 and duplicate listings), and the listening state for SSH ontcp6is correctly shown.dmytro_rak_09/6. sudo iptables -L -v -n and sudo ufw status verbose.txt (1)
33-174: Review of detailed iptables chains and logging rules.
This section displays all the configured UFW chains—including those for logging, policy skipping, and tracking—detailing packet and byte counts for each rule. The configuration appears comprehensive and is well-documented in the snapshot; however, consider verifying that the configured logging limits (e.g., average rate and burst settings) meet the diagnostic requirements during troubleshooting scenarios.
