    Plesk VPS: The Benefits Plesk Offers to Your Virtual Private Server

    TOC

    Plesk stands as one of the most versatile and powerful hosting control panels available today, trusted by web professionals, developers, and hosting companies worldwide. For those managing a Virtual Private Server, Plesk transforms server administration from a complex technical undertaking into an accessible, streamlined process. This comprehensive guide explores the significant benefits that Plesk delivers to your VPS hosting environment.

    What is Plesk VPS?

    Plesk is a powerful, web-based control panel designed to simplify the management of websites, servers, and applications on your virtual private server. Unlike control panels limited to specific operating systems, Plesk works seamlessly on both Linux and Windows VPS environments, providing consistent functionality across platforms. The control panel offers a centralized interface to deploy, configure, monitor, and secure your VPS—making sophisticated server management accessible to users of all technical skill levels.

    Intuitive, User-Friendly Interface

    Plesk’s greatest strength lies in its exceptionally clean and intuitive interface that makes complex server tasks feel simple. Rather than wrestling with command-line operations or navigating confusing menu structures, you manage your entire VPS through organized menus, visual dashboards, and straightforward forms.​

    The control panel organizes all essential functions in one place—launching sites, configuring domains, managing email accounts, setting up databases, and running updates. Everything is centralized so you can quickly accomplish work without jumping between multiple tools or interfaces. Even complex tasks like creating and managing user accounts or installing web applications like Joomla or Drupal become point-and-click operations.​

    This user-centric design philosophy means your team—regardless of technical expertise—can immediately become productive. Administrators spend less time learning software and more time managing your hosting infrastructure. The clean, logical interface reduces frustration and errors, enabling faster task completion across your entire VPS environment.

    Cross-Platform Compatibility: Linux and Windows


    Plesk offers a unique advantage unavailable in competing control panels: seamless support for both Linux and Windows operating systems. This cross-platform compatibility gives you flexibility that other control panels cannot match.​

    Linux support includes:

    Complete compatibility with popular Linux distributions, supporting the full LAMP/LEMP stack (Linux, Apache/Nginx, MySQL/PostgreSQL, PHP/Python/Perl). This makes Plesk ideal for traditional web hosting environments.​

    Windows support includes:

    Plesk is one of the few professional control panels available for Windows servers, supporting .NET applications, ASP.NET frameworks, and MSSQL databases. This is particularly valuable for businesses running Windows-based applications that require specialized environments.​

    This cross-platform architecture means you don’t need to change control panels when switching between operating systems. Your hosting infrastructure can accommodate diverse project requirements—WordPress sites on Linux, ASP.NET applications on Windows—all managed from the same Plesk interface.

    Built-In Security Tools for Peace of Mind

    Security is paramount in modern hosting environments, and Plesk provides enterprise-grade security features directly integrated into the control panel.​

    Plesk’s comprehensive security arsenal includes:

    • ModSecurity integration: A Web Application Firewall that protects against common web attacks. 
    • Fail2Ban integration: Brute-force protection that automatically blocks repeated unauthorized login attempts. 
    • Built-in firewall: Network-level firewall with granular rule configuration.

    These layered security measures work together to create multiple defensive barriers against attacks. The Security Advisor automatically monitors your server environment, applying patches and hardening configurations without requiring manual intervention. This proactive approach means your VPS remains protected against emerging threats while you focus on your business.

    Centralized Management for Multiple Websites

    Managing multiple projects or client accounts becomes effortless with Plesk’s centralized dashboard. Whether you’re running five websites or fifty, you maintain complete oversight from a single login.​

    Multi-site management features include:

    • User account creation: Set up separate user accounts with custom permissions for different team members or clients.

    This centralized approach eliminates the need to juggle multiple control panels or login credentials. Everything you need to manage your entire hosting operation is available in one interface, significantly reducing administrative complexity and improving operational efficiency.

    WordPress Toolkit: A Game-Changing Feature

    For users managing WordPress sites, Plesk includes a dedicated WordPress Toolkit that simplifies WordPress hosting from top to bottom—one of the most powerful integrated features in any control panel.​

    Whether you’re experiencing unexpected traffic growth or planning for expansion, Plesk VPS hosting accommodates changing needs without forcing disruptive server migrations. This flexibility is particularly valuable for growing businesses where hosting needs change frequently.

    Reseller and Client Management Capabilities

    For web agencies, hosting companies, and freelancers, Plesk transforms a single VPS into a complete, professional hosting business platform.

    Reseller capabilities include:

    Separate client accounts: Create multiple customer accounts with complete isolation and security. 

    Custom resource allocation: Define specific resource limits for each client—CPU, RAM, disk space, and bandwidth. 

    White-label branding: Apply your brand identity to the control panel interface presented to each client. 

    Multi-level access control: Create admin accounts, reseller accounts, and limited user accounts with specific permissions. 

    Automated billing integration: Connect to billing systems for automatic invoice generation and account management.

  • Managed VPS vs Unmanaged VPS Hosting: What’s the Difference?

    Managed VPS vs Unmanaged VPS Hosting: What’s the Difference?

    TOC

    When it comes to choosing a Virtual Private Server, one of the most critical decisions you’ll make is whether to opt for managed or unmanaged hosting. On the surface, this choice seems straightforward but it carries profound implications for your budget, peace of mind, and operational efficiency. A managed VPS transfers server administration tasks to your hosting provider, freeing you to focus on growing your business. An unmanaged VPS puts you in complete control but demands technical expertise and ongoing attention.

    At Computeman, Inc., we understand that different businesses have different needs. Some teams thrive with full control and technical autonomy, while others prefer delegating infrastructure management to specialists. This comprehensive guide breaks down both approaches, helping you make an informed decision aligned with your goals, budget, and technical capabilities.

    Understanding the Core Difference

    What Is Managed VPS Hosting?

    Managed VPS hosting is a turnkey solution where your hosting provider shoulders the responsibility for server administration, maintenance, and optimization. You receive a provisioned, ready-to-use server with your choice of operating system and pre-configured software stack. The provider handles everything behind the scenes: security patches, system updates, software installations, backups, monitoring, and performance optimization.​

    Think of managed VPS as hiring a dedicated IT operations team. You own the business logic and application layer; your provider owns the infrastructure layer.

    What Is Unmanaged VPS Hosting?

    Unmanaged VPS hosting is the DIY option. You receive a bare-bones server with just an operating system installed. From there, you’re entirely responsible for configuration, software installation, security management, updates, backups, monitoring, and troubleshooting. It’s powerful and flexible, but demands expertise and time.

    Unmanaged VPS is like renting an empty warehouse where you have complete freedom to build it exactly as you want, but the responsibility for every aspect falls squarely on you.

  • What Is VPS? Complete Guide to Virtual Private Servers

    What Is VPS? Complete Guide to Virtual Private Servers

    TOC

    Introduction

    If you’re launching a website, building a web application, or scaling your online presence, you’ve likely encountered the term VPS (Virtual Private Server). For many, the concept feels intimidating, surrounded by technical jargon and unfamiliar terminology. But the truth is simple: a VPS is a powerful, affordable middle-ground solution that sits between basic shared hosting and expensive dedicated servers. At Computeman, Inc., we believe every entrepreneur and business owner deserves access to reliable infrastructure that grows with their ambitions. This guide demystifies VPS hosting, explaining what it is, how it works, and whether it’s the right choice for you.

    Understanding VPS: The Foundation

    What Exactly Is a Virtual Private Server?

    A Virtual Private Server is a virtualized hosting environment created by partitioning a single physical server into multiple isolated virtual machines. Each virtual machine operates independently, with its own dedicated resources including CPU cores, RAM, storage, and bandwidth where all running separately from other users on the same physical hardware. The key word here is dedicated: your resources are yours alone, not shared or competed for by neighboring websites.​

    To visualize this, think of a VPS as owning a private apartment in a larger building. You have your own dedicated space, utilities, and security, but the building’s foundation and infrastructure are shared with other residents. Each apartment operates independently, and what your neighbors do doesn’t directly affect your comfort or access to services.

    How Does VPS Hosting Actually Work?

    The magic behind VPS hosting lies in virtualization technology, specifically a piece of software called a hypervisor. Here’s the step-by-step process.

    • Physical Server Setup – Your hosting provider maintains powerful physical servers equipped with substantial computing resources.
    • Virtual Layer Creation – A hypervisor is installed on the physical server’s operating system, acting as a bridge between the hardware and your virtual environment.
    • Resource Partitioning – The hypervisor divides the server’s CPU, RAM, storage, and bandwidth into isolated virtual environments, each assigned to a different customer.
    • Independent Operation – Each virtual server runs its own operating system (Linux, Windows, or other options) and can be configured entirely separately from its neighbors.
    • Root Access – You receive full administrative (root) access to your virtual server, allowing you to install software, modify settings, and manage your environment as if you owned a physical machine.

    The result: a complete, isolated hosting environment that feels like having your own private server but at a fraction of the cost.

    VPS vs. Other Hosting Options

    To truly understand why VPS hosting matters, it helps to compare it with other common solutions.

    VPS vs. Shared Hosting

    Shared Hosting works like a communal workspace where dozens or even hundreds of websites share a single server and its resources. You pay less, but your website’s performance depends on how heavily your neighbors’ sites are using the server. If another website suddenly experiences a traffic spike, your site can slow down or even become temporarily unavailable.​

    VPS Hosting isolates you from these “noisy neighbor” problems. Your resources are reserved exclusively for you, meaning traffic spikes affecting other users won’t impact your site’s performance. Performance remains consistent regardless of what other websites on the server are doing.

    Bottom line: If your shared hosting site occasionally crashes during traffic surges or you need custom software installed, VPS hosting is a logical upgrade.

    VPS vs. Dedicated Servers

    A Dedicated Server means you rent an entire physical server exclusively for your use but at premium cost ($100–$500+/month).

    A VPS gives you most of the benefits of a dedicated server (root access, customization, performance) at a fraction of the price, because you’re sharing the underlying hardware with other customers. For most growing businesses, a VPS delivers 90% of the power at 30–40% of the cost.

    Key Benefits of VPS Hosting

    Dedicated Resources You Can Count On

    With a VPS, your CPU cores, RAM, and storage are guaranteed and won’t fluctuate based on other users’ activity. This predictability makes it easier to plan capacity and ensure consistent performance.

    Complete Root Access and Control

    You get full administrative access to your server, enabling you to:

    • Install any software or application you need
    • Modify server configurations and settings
    • Compile custom code and frameworks
    • Configure security settings to your exact specifications

    This freedom is impossible on shared hosting, where your options are limited by what the provider pre-configures.

    Enhanced Security

    Because your virtual environment is isolated, security vulnerabilities affecting other websites on the server won’t compromise your site. You also have control over your own firewall, security patches, and access controls which are unattainable in shared hosting where your security depends partly on the hosting company’s choices for the entire server.

    Scalability Without Downtime

    As your traffic and data grow, upgrading a VPS is straightforward. You can increase CPU cores, RAM, and storage quickly often without restarting your site. This flexibility means your hosting grows with your business.

    Cost-Effectiveness

    Compared to dedicated servers, VPS hosting is remarkably affordable, delivering comparable flexibility and power at 30–40% of the price.

    Types of VPS Hosting

    When choosing a VPS, you’ll encounter a few variations worth understanding.

    Managed vs. Unmanaged VPS

    Unmanaged VPS – You handle all server administration: updates, security patches, backups, monitoring, and troubleshooting. It’s cheaper but requires technical expertise.

    Managed VPS – Your hosting provider handles these tasks, freeing you to focus on your application or website. You pay more, but get peace of mind and ongoing support.

    Semi-Managed VPS – A hybrid approach where the provider handles certain tasks (backups, updates) while you manage others.

    Operating System Options

    Linux VPS – The most common option, favored for its security, stability, cost-effectiveness, and compatibility with popular web applications like WordPress, Drupal, and custom frameworks.

    Windows VPS – Required if you’re using Windows-specific software, Microsoft SQL Server, or ASP.NET applications.

    Cloud VPS

    Cloud VPS takes the concept further by leveraging resources from multiple servers worldwide rather than a single physical machine. This approach offers superior redundancy and reliability. If one data center has issues, others automatically fill the gap. It’s ideal for businesses demanding maximum uptime.

    Ideal Use Cases for VPS Hosting

    Growing Websites – Your site has outgrown shared hosting’s performance limits, with traffic spikes or frequent traffic growth.

    Web Applications – You’re running custom software, APIs, or frameworks requiring specific configurations and root access.

    E-commerce Stores – Your online shop needs reliable performance, custom integrations, and enhanced security.

    Development & Testing – Developers use VPS for isolated staging environments, testing, and deploying applications before production release.

    Multiple Websites – Managing several domains or projects on separate isolated environments.

    VPN & Proxy Services – A VPS can be configured as a VPN or proxy server for enhanced privacy and security.

    Database & Backup Storage – Use VPS as a secure offsite backup or database server.

    Choosing the Right VPS Provider: Key Factors

    Server Resources

    Evaluate what each plan offers:

    • CPU Cores – More cores handle concurrent requests better. For most websites, 2–4 cores suffice; high-traffic sites may need 8+.
    • RAM – Memory determines how many applications run simultaneously. Start with 2–4 GB; scale as needed.
    • Storage Type – NVMe SSDs are significantly faster than traditional HDDs. For performance-critical sites, NVMe is non-negotiable.​
    • Bandwidth – Ensure the plan includes sufficient data transfer. Unlimited or high-cap bandwidth is preferable for growing sites.

    Uptime Guarantee

    Look for providers offering 99.9% uptime SLA (Service Level Agreement). This means your site is down less than ~45 minutes per year.

    Performance & Hardware Quality

    Top-tier providers use modern processors (Intel Xeon, AMD EPYC, or AMD Ryzen), NVMe storage, and redundant networks. Ask about data center locations and whether they support IPv6 and modern performance technologies like HTTP/3.

    Scalability

    Can you easily upgrade resources without migrating to a different server? True scalability means seamless growth.

    Security Features

    Ensure the provider offers:

    • DDoS protection
    • SSL certificates
    • Firewall configuration
    • Automated backups
    • Regular security patching

    Support Quality

    24/7 support is essential. Test their responsiveness before signing up. Many providers offer live chat or phone support for rapid issue resolution.

    Control Panel

    A intuitive dashboard (like cPanel) makes server management far easier, especially if you’re less technical.

    Common Misconceptions About VPS

    “VPS is too technical for me.” – While VPS requires more technical knowledge than shared hosting, managed VPS options abstract most complexity away. Modern control panels make it accessible to anyone.

    “Dedicated servers are always better.” – Not necessarily. For most growing businesses, a VPS offers the right balance of performance, control, and cost. Dedicated servers are overkill unless you’re running truly massive operations.

    “VPS is always cheaper than shared hosting.” – VPS costs more upfront, but delivers vastly superior performance and reliability. The investment pays dividends through improved user experience and fewer crashes.

    Conclusion

    A Virtual Private Server represents the modern sweet spot for serious online ventures. It delivers the control, performance, and security of a dedicated server without the prohibitive cost. Whether you’re a growing e-commerce store, a developer building custom applications, or a business running multiple projects, VPS hosting provides the foundation for reliable, scalable growth.​

  • Understanding the Modern GPU – Engine of Parallel Processing

    Understanding the Modern GPU – Engine of Parallel Processing

    TOC

    While nearly every computer has one, the Graphics Processing Unit (GPU) has evolved far beyond its original purpose. Today, it’s a powerhouse driving revolutions in artificial intelligence, scientific discovery, and immersive experiences. But what fundamentally is a GPU, and how does it differ from the Central Processing Unit (CPU) that serves as the traditional brain of a computer?

    The Core Difference: Specialized Parallelism

    The key lies in their architectural design philosophy:

    CPU (Central Processing Unit)

    Designed as a “jack-of-all-trades.” A typical modern CPU has a relatively small number of powerful, complex cores (e.g., 4, 8, 16, 32). These cores excel at handling diverse, sequential tasks quickly – running operating systems, applications, logic, and complex decision-making where tasks often depend on the results of previous ones (sequential processing). CPUs prioritize low latency, meaning getting a single task done as fast as possible (Intel, 2023; AMD, 2023).

    GPU (Graphics Processing Unit)

    Designed as a “master of many similar tasks.” A GPU contains thousands of smaller, simpler, and highly efficient cores optimized for a specific type of workload: massively parallel processing. Rendering complex graphics involves performing the same mathematical operations (like calculating lighting, color, and position) simultaneously on millions of pixels or vertices. A GPU’s architecture is built to tackle vast numbers of these simple, repetitive calculations concurrently (NVIDIA, 2023).

    Anatomy of a GPU: Built for Throughput

    This parallel focus shapes the GPU’s physical and logical structure:

    • Thousands of Cores: Modern GPUs pack thousands of processing cores (e.g., NVIDIA’s Ada Lovelace architecture boasts tens of thousands of CUDA Cores). While individually less powerful than a CPU core, their sheer number allows for immense throughput – processing massive datasets simultaneously (NVIDIA, 2023).
    • Wide Memory Interface: To feed data to all these cores without bottlenecks, GPUs connect to specialized, high-speed Video RAM (VRAM) like GDDR6 or HBM2e via a very wide memory bus (e.g., 384-bit, 512-bit). This provides significantly higher memory bandwidth than typical CPU RAM (JEDEC, 2023).
    • Specialized Hardware: Beyond generic cores, modern GPUs include dedicated hardware units:
      • RT Cores (Ray Tracing): Accelerate complex calculations for realistic lighting and shadows in real-time rendering (NVIDIA, 2023).
      • Tensor Cores: Specifically designed for the matrix multiplication operations that are fundamental to deep learning and AI workloads (NVIDIA, 2023; AMD, 2023 – referencing their Matrix Cores).
    • Software Ecosystem: APIs like CUDA (NVIDIA), ROCm (AMD), and OpenCL allow programmers to harness the GPU’s parallel power for non-graphics tasks, known as General-Purpose computing on GPU (GPGPU) (Khronos Group, 2023; NVIDIA, 2023).

    Beyond Pixels: The Rise of GPGPU

    The realization that the GPU’s parallel architecture was incredibly efficient for certain non-graphics tasks sparked the GPGPU revolution. Any application that can be broken down into many smaller, independent tasks can potentially run much faster on a GPU:

    • Artificial Intelligence & Deep Learning: Training complex neural networks involves performing billions of matrix multiplications across massive datasets – a task perfectly suited for the parallel nature and tensor cores of modern GPUs. This is the engine behind breakthroughs in image recognition, natural language processing, and more (IEEE Spectrum, 2021).
    • High-Performance Computing (HPC): Scientific simulations (climate modeling, molecular dynamics, fluid dynamics) involve solving complex equations across vast grids or particle systems, inherently parallel problems where GPUs offer massive speedups over CPUs alone (Top500.org, 2023).
    • Data Science & Analytics: Processing and analyzing massive datasets for trends, patterns, and insights benefits greatly from GPU acceleration in tasks like data filtering, transformation, and complex statistical modeling (TechTarget, 2022).
    • Content Creation: Video editing (especially effects rendering and encoding), 3D animation rendering, and complex image processing leverage GPU power for significantly faster workflows (Adobe, 2023; Blender Foundation, 2023).
    • Advanced Graphics: Of course, rendering increasingly realistic and complex scenes in games, virtual reality (VR), and augmented reality (AR) remains a core function, continuously pushing GPU technology forward.

    Conclusion: The Parallel Workhorse

    A GPU is no longer just a graphics card. It is a highly specialized parallel processor engineered for raw computational throughput on tasks that can be executed simultaneously. While the CPU remains essential for general system management and complex sequential logic, the GPU has become indispensable for accelerating the massively parallel workloads that define modern computing frontiers: AI, scientific discovery, large-scale data analysis, and ever-more immersive visual experiences. Its evolution from a graphics renderer to a general-purpose computational powerhouse underscores its critical role in our technological landscape.

    How to add custom code to WordPress header and footer in functions.php

      TOC

      Overview

      If you want to install chat widget on your wordpress website or want to add HotJar, Google Analytics, or other third party app script, it can be done easily by adding a code in the functions.php in wordpress instead of installing a wordpress plugin. Adding a wordpress header and footer code insertion plugin may very likely will slow your website.

      With the latest WordPress external link updates, header.php and footer.php are not available to edit in Tools -> The File Editor, so the best option is to put the code in functions.php.

      Steps

      Add code to WordPress header

      Use the wp_head hook to add content dynamically to header.php. Add the following code to functions.php in Child theme. If you do not have a Child theme than add it in your main theme functions.php by going to Tools -> The File Editor -> functions.php.

      add_action('wp_head', 'your_function_name');
      function your_function_name(){
      echo '<script> your custom code pasted here </script>';
      }

      Add code to WordPress footer

      Use the wp_head hook to add content dynamically to footer.php. Add the following code to functions.php in Child theme. If you do not have a Child theme than add in your main theme functions.php by going to Tools -> The File Editor -> functions.php.

      add_action('wp_footer', 'your_function_name');
      function your_function_name(){
      echo '<script>  your custom code pasted here </script>';
      }

      Make sure you change your_function_name at two places in the above codes and add your app script in place of ‘your custom code pasted here’. You can any code in this place.

      If you are not using child theme, this code added in functions.php may be overwriiten after a theme update. So, you may need to add this code again after a theme update if you are not using child theme.

    • SUDO allow normal user to run command as root

      SUDO allow normal user to run command as root

      TOC

      Overview

      sudo enables users to execute root commands on a Linux dedicated server as a normal user. Unlike the su command, sudo offers greater flexibility and enhanced security.

      A key benefit of sudo is its ability to log usage, with log entries typically stored in the /var/log/secure file. The sudo program relies on the /etc/sudoers configuration file to define the rules that determine whether a command can be executed.

      Steps

      It is advisable to use the visudo utility, included with the sudo package, for editing the /etc/sudoers file. For instance, if we want a user named user to execute commands as root, we can start by using sudo to run a command that requires elevated permission.

      $ sudo /sbin/service sendmail restart
      Password:
      normaluser is not in the sudoers file.  This incident will be reported.

      The sudo command has logged the attempt to the log file /var/log/secure as shown below.

      # tail /var/log/secure
      ...
      Aug  2 14:37:49 somehost sudo:  user : user NOT in sudoers ;
      TTY=pts/2 ; PWD=/home/user ; USER=root ;
      COMMAND=/sbin/service sendmail restart

      On all Linux servers, there is a specific group called ‘wheel’ that is commonly associated with privileged operations. To include a user in the supplementary ‘wheel’ group, run the following command as the root user.

      # usermod -aG wheel user

      Verify that the user is now a member of the ‘wheel’ group.

      # groups user
      user : user wheel

      Edit the file /etc/sudoers using the visudo command as follows.

      # sudoers file.
      #
      # This file MUST be edited with the 'visudo' command as root.
      #
      # See the sudoers man page for the details on how to write a sudoers file.
      #
      
      # Host alias specification
      
      # User alias specification
      
      # Cmnd alias specification
      
      # Defaults specification
      
      # User privilege specification
      root    ALL=(ALL) ALL
      
      # Uncomment to allow people in group wheel to run all commands
      # %wheel ALL=(ALL)       ALL
      
      # Same thing without a password
      # %wheel        ALL=(ALL)       NOPASSWD: ALL
      
      # Samples
      # %users  ALL=/sbin/mount /cdrom,/sbin/umount /cdrom
      # %users  localhost=/sbin/shutdown -h now

      Take note that the /etc/sudoers file features examples and comments. To grant members of the ‘wheel’ group the ability to execute commands as root with sudo, you should uncomment the specified line.

      ...
      # Uncomment to allow people in group wheel to run all commands
      %wheel ALL=(ALL)       ALL
      ...

      The visudo utility utilizes key bindings and commands derived from the vi editor. To edit the visudo file, press ‘i’ to enter Insert mode. Use the cursor keys to position the cursor correctly, and press ‘Delete’ to remove the ‘#’ character. To save your modifications, hit the escape key, then type ‘:write’, and finally ‘:quit’ to exit.

      ...
      # Uncomment to allow people in group wheel to run all commands
      %wheel ALL=(ALL)       ALL
      
      #Same thing without a password
      # %wheel        ALL=(ALL)       NOPASSWD: ALL
      
      # Samples
      # %users  ALL=/sbin/mount /cdrom,/sbin/umount /cdrom
      # %users  localhost=/sbin/shutdown -h now
      
      # ALL     ALL = NOPASSWD: /usr/bin/mindspring

      Now run the privileged commands again as normal user.

      $ sudo /sbin/service sendmail restart
      Password:
      Shutting down sendmail:                                    [  OK  ]
      Shutting down sm-client:                                   [  OK  ]
      Starting sendmail:                                         [  OK  ]
      Starting sm-client:                                        [  OK  ]

      The successful execution of sudo will also be logged in the /var/log/secure file.

      # tail /var/log/secure
      ...
      Aug  2 15:05:49 somehost sudo:  user : TTY=pts/2 ;
      PWD=/home/user ; USER=root ;
      COMMAND=/sbin/service sendmail restart
