Linux systems administrators, who are typically referred to as “sysadmins” within a company, are responsible for the configuration, maintenance, and overall function of computer systems that run Linux. These tasks relate both to hardware and software aspects of the network. The scope of the position may vary widely according to employers' needs. For example, smaller businesses might use a system composed of a limited number of peer-to-peer connections and perhaps a modest central server. Linux systems administrators who work for large corporations are likely to work as part of a sizable team that maintains a network including thousands of workstations and numerous servers. If the company includes multiple sites, administrators are also likely to maintain a virtual private network.
