bash

# Check if service is listening
sudo ss -tlnp | grep 8000

# Test connectivity
telnet localhost 8000

# Check firewall
sudo firewall-cmd --list-all

3. Performance issues:

bash

# Check resource usage
top -p $(pgrep lnx)

# Check disk I/O
iotop -p $(pgrep lnx)

# Check connections
ss -an | grep 8000
