UNIX System Administration
The system administrator will need to maintain the software and hardware for the system which includes hardware configuration, software installation, reconfiguration of the kernel, and networking to keep it running in a satisfactory manner.
Almost every system manager has to deal with user accounts, system startup and shutdown, peripheral devices, system performance, and security. While the commands and procedures you use in each of these areas vary widely across different computer systems, the general approach to such issues can be remarkably similar. Add the user to the user account database, allocate some disk space for him, assign a password to the account, enable him to use major system facilities and applications, and so on. Only the commands to perform these tasks are different on different systems.
Installation and Deployment
- Installing and configuring operating system software and associated patches or updates
- Installing and configuring components required to work with Stanford’s central computing infrastructure (Kerberos, AFS, and associated PAM modules, WebAuth, remote, wallet client, etc.)
- Installing and configuring application software per special arrangement with client
- Performing standard installation verification activities Executing application installation commands that require special privileges
- Requesting and ensuring proper backup and system firewall templates have been applied
- Installing systems and configuration management tools
- Setting up basic monitoring probes (disk, load, swap, ping), as well as any application-specific monitoring probes per agreement with the client.
- Configure backups as required by the client.
Innovation Consulting introduces document framework Intrusion Detection programming on all hosts and is answerable for the continuous support of that product. This document framework Intrusion Detection programming is expected to screen the trustworthiness of framework programming and bundles introduced by Technology Consulting, not client-introduced application programming. Registries that show incessant client-started changes will be rejected from the interruption discovery report.
Monitoring and Alerting
The strength of a server is checked by means of the framework observing instrument, Nagios. Checks for Web, Tomcat, and different ports or administrations are excluded from the central help, but rather are accessible by game plan with the client. Frequencies and limits of observing checks are set by industry best practices. Changes to the recurrence or edge of an observing check will be viewed as an exceptional solicitation and may cause extra expenses.
