# How to Test a Server Before Committing to a Rental

This article details the essential steps for thoroughly testing a server *before* committing to a long-term rental.  Proper testing can save you significant downtime, data loss, and frustration. We’ll cover network connectivity, resource availability, disk I/O, and basic application functionality. This guide assumes you have shell access (SSH) to the server. Remember to familiarize yourself with [[Server Administration]] basics before proceeding.

== 1. Initial Server Access & Basic Information==

Before launching into complex tests, verify basic access and gather essential server information. This initial check confirms you can even *reach* the server and get a baseline understanding of its configuration.

*   **SSH Access:** Ensure you can connect via SSH using your preferred client.  Verify your user account has appropriate permissions.
*   **Operating System:** Determine the operating system and version.  This impacts the tools available and expected behavior. Use `uname -a` for Linux systems.
*   **Kernel Version:** Check the kernel version using `uname -r`. This can reveal potential compatibility issues with certain software.
*   **Uptime:**  `uptime` shows how long the server has been running.  Unexpectedly short uptime might indicate instability.

== 2. Network Connectivity Testing==

Reliable network connectivity is paramount.  These tests verify the server can communicate with the outside world and that network performance is acceptable.

*   **Ping:**  Test basic reachability to known external hosts.  `ping 8.8.8.8` (Google's public DNS) is a good starting point.  Look for consistent response times and minimal packet loss.
*   **Traceroute/Tracepath:**  Identify the network path to a destination. `traceroute 8.8.8.8` (or `tracepath 8.8.8.8` if traceroute is unavailable) helps pinpoint network bottlenecks.
*   **DNS Resolution:**  Verify the server can resolve domain names. `nslookup google.com` (or `dig google.com`) checks DNS functionality.
*   **Bandwidth Testing:**  Measure the server’s upload and download speeds. Tools like `speedtest-cli` (install if needed) provide estimates.

Here’s a table summarizing expected results:

{| class="wikitable"
! Test
! Expected Result
! Failure Indication
|-
| Ping 8.8.8.8
| Consistent responses, low latency (under 50ms)
| Packet loss, high latency
|-
| Traceroute 8.8.8.8
| Clear path to the destination
| Loops, high latency hops
|-
| DNS Resolution (google.com)
| Correct IP address returned
| Resolution failure, incorrect IP address
|-
| Bandwidth Test
| Speeds close to advertised
| Significantly lower speeds
|}

== 3. Resource Availability & Performance==

Assess the server’s CPU, memory, and disk resources. These tests identify potential bottlenecks that could impact application performance.  Consider [[Resource Monitoring]] as a continuous process once your server is live.

*   **CPU Information:**  `lscpu` (Linux) provides detailed CPU information.  Pay attention to core count, clock speed, and cache size.
*   **Memory Usage:**  `free -m` displays memory usage in megabytes.  Check total memory, used memory, and swap usage. High swap usage indicates memory pressure.
*   **Disk Space:**  `df -h` shows disk space usage. Ensure sufficient free space is available for your applications and data.
*   **I/O Performance:**  `hdparm -tT /dev/sda` (replace `/dev/sda` with your disk device) tests disk read performance.  `dd` can be used for more complex I/O tests, but be careful as it can generate significant disk activity.

Here’s a table outlining acceptable resource levels (these will vary based on your application requirements):

{| class="wikitable"
! Resource
! Minimum Acceptable
! Recommended
! Warning Level
|-
| CPU Cores
| 2
| 4+
| Sustained 90%+ usage
|-
| RAM
| 4 GB
| 8 GB+
| Swap usage consistently > 20%
|-
| Disk Space
| 20 GB free
| 50 GB+ free
| < 10% free
|-
| Disk Read Speed
| 50 MB/s
| 100 MB/s+
| < 20 MB/s
|}

== 4. Basic Application Functionality Testing==

Once network and resources are verified, test the core functionality you’ll be relying on. This is application-specific, but some common tests include:

*   **Web Server:** If using a web server (e.g., Apache, Nginx), test serving static files and executing basic scripts (e.g., PHP). See [[Web Server Configuration]] for details.
*   **Database Server:**  If using a database (e.g., MySQL, PostgreSQL), test connection, query execution, and data insertion. Consult [[Database Administration]] guides.
*   **Mail Server:** If using a mail server, test sending and receiving emails. Refer to [[Email Server Setup]].
*   **Firewall:** Verify the firewall is configured correctly and allowing necessary traffic.  See [[Firewall Configuration]].

Below is a table example for a basic PHP test:

{| class="wikitable"
! Test
! Steps
! Expected Result
|-
| PHP Info Page
| Create a `info.php` file with `<?php phpinfo(); ?>` content. Access it via your web browser.
| PHP configuration information is displayed.
|-
| Database Connection
| Write a PHP script to connect to your database.
| Successful database connection without errors.
|-
| File Upload
| Attempt to upload a small file via a PHP script.
| File is uploaded successfully and stored on the server.
|}

== 5. Security Considerations==

Don't overlook security during your testing phase.

*   **Firewall Rules:** Confirm firewall rules are appropriately configured to restrict unnecessary access.
*   **SSH Security:** Ensure SSH access is secured with strong passwords or key-based authentication. Disable password authentication if possible.
*   **Default Accounts:**  Check for and disable or change passwords for default accounts.
*   **Security Updates:** Verify the operating system and installed software are up-to-date with the latest security patches.  See [[Server Security Best Practices]].

== 6. Documentation and Reporting ==

Document all your testing procedures and results. This documentation will be invaluable for troubleshooting later.  Create a detailed report outlining any issues discovered and how they were resolved. This will help you make an informed decision about committing to the server rental.  Consider using a [[Server Documentation Template]] for consistency.
