Troubleshooting

Common Issues

Web Interface Not Loading:

# Check Apache status
sudo systemctl status apache2

# Check Apache error logs
sudo tail -f /var/log/apache2/squert_error.log

# Check PHP errors
sudo tail -f /var/log/apache2/error.log|grep -i php

# Verify file permissions
sudo chown -R www-data:www-data /var/www/squert
sudo chmod -R 755 /var/www/squert

# Test PHP configuration
php -m|grep -i mysql
php -r "phpinfo();"|grep -i mysql

Database Connection Issues:

# Test database connection
mysql -h localhost -u squert -p sguildb -e "SELECT COUNT(*) FROM event;"

# Check database permissions
mysql -u root -p -e "SHOW GRANTS FOR 'squert'@'localhost';"

# Verify database configuration
cat /var/www/squert/.scripts/squert.inc|grep -E "(dbhost|dbuser|dbpass|dbname)"

# Check MySQL service
sudo systemctl status mysql
sudo systemctl start mysql

Performance Issues:

# Check system resources
top -p $(pgrep apache2)
free -h
df -h

# Optimize database
mysql -u squert -p sguildb -e "OPTIMIZE TABLE event;"
mysql -u squert -p sguildb -e "ANALYZE TABLE event;"

# Check slow queries
mysql -u root -p -e "SHOW PROCESSLIST;"

# Enable PHP OPcache
echo "opcache.enable=1" >> /etc/php/7.4/apache2/php.ini
sudo systemctl restart apache2

Performance Optimization

Optimizing Squert performance:

# Apache optimization
cat >> /etc/apache2/conf-available/squert-performance.conf << 'EOF'
# Squert performance optimizations

# Enable compression
LoadModule deflate_module modules/mod_deflate.so
<Location "/squert">
    SetOutputFilter DEFLATE
    SetEnvIfNoCase Request_URI \
        \.(?:gif|jpe?g|png)$ no-gzip dont-vary
    SetEnvIfNoCase Request_URI \
        \.(?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip dont-vary
</Location>

# Enable caching
LoadModule expires_module modules/mod_expires.so
<Location "/squert">
    ExpiresActive On
    ExpiresByType text/css "access plus 1 month"
    ExpiresByType application/javascript "access plus 1 month"
    ExpiresByType image/png "access plus 1 month"
    ExpiresByType image/jpg "access plus 1 month"
    ExpiresByType image/jpeg "access plus 1 month"
    ExpiresByType image/gif "access plus 1 month"
</Location>

sudo systemctl restart apache2

Security Considerations

Access Control

Web Interface Security:

• Implement HTTPS for all Squert access
• Use strong authentication mechanisms
• Implement session timeout and management
• Regular security updates for all components
• Monitor access logs for suspicious activity

Database Security:

• Use dedicated database user with minimal privileges
• Implement database connection encryption
• Regular database security updates
• Monitor database access logs
• Implement backup encryption

Data Protection

Event Data Security:

• Encrypt sensitive event data at rest
• Implement data retention policies
• Secure access to packet capture data
• Regular cleanup of temporary files
• Implement access logging for event data

Operational Security:

• Regular security assessments of Squert infrastructure
• Monitor for unauthorized access attempts
• Implement proper backup and recovery procedures
• Regular updates of Squert and dependencies
• Incident response procedures for Squert compromise
