Software
From Wiki CEINGE
A number of software programs run on central computers and are used to build and integrate the IT services. They are installed, configured and constantly updated to guarantee a reliable service to the final user.
Here follows a short description of them:
- Apache WebServer
- It is a secure, efficient and extensible server that provides HTTP services. It provides a wide range of application services, used for researcher activities and delivery of bioinformatics applications.
- BigBrother
- Big Brother monitors System and Network-delivered services for availability. When problems are detected, the system manager is immediately notified by e-mail, pager, or text messaging.
- BigSister
- Big Sister is an alternative to the big brother software as system and network monitor and provides improved characteristics, like graphical statistics of the history, through RRDTools.
- ClamAV antivirus
- Clam AntiVirus is an anti-virus toolkit for UNIX, designed for e-mail scanning on mail gateways. It provides a flexible and scalable multi-threaded daemon, a command line scanner, and an advanced tool for automatic database updating via Internet.
- Cluster scheduling
- PHP system to schedule interactive processes on distributed computing machines; it also provides a web interface to monitor the load distribution.
- Condor
- The goal of the Condor® Project is to develop, implement, deploy, and evaluate mechanisms and policies that support High Throughput Computing (HTC) on large collections of distributively owned computing resources.
- DHCP (Automatic IP assignment)
- This service provides IP addresses for users that have registered their own laptop and want access the network. There are several private networks designed for this purpose, associated to different areas of the institute.
- Fileserver
- A central disk space used by users to
- store
- share files by network
- the access is guaranteed using different standard protocols (afp, ftp, windows file sharing).
- LDAP user management
- Provides accounting information; it is used for authentication from all the central services with restricted access.
- Red Hat Diskless Environment
- Some networks require multiple systems with the same configuration. They also require that these systems be easy to reboot, upgrade, and manage. One solution is to use a diskless environment in which most of the operating system, which can be read-only, is shared from a central server between the clients and the individual clients have their own directories on the central server for the rest of the operating system, which must be read/write. Each time the client boots, it mounts most of the OS from the NFS server as read-only and another directory as read-write. Each client has its own read-write directory so that one client can not affect the others.
- RRDTools
- A graphic library to display statistic data.
- Rsync
- Copies files between machines, using different network protocols as transport, such as secure shell (ssh).
- Sendmail mailserver
- Provide a stable and efficient way to deliver emails for registered users.
- SpamAssassin antispam
- Users mailbox management
- The management of mailboxes implies the control of the space used by the mail service for each user; this control provides a way to store old mail on the fileserver for each user in his personal home.
- VLS Virtual Linux Station
- Provides access to a remote linux desktop; it is useful to run scientific applications that requires a Unix OS as platform.
- Webmail
- A web interface to access the mail server.
- Webmin
- Webmin is a web-based interface for system administration for Unix. Using any browser that supports tables and forms (and Java for the File Manager module), you can setup user accounts, Apache, DNS, file sharing and so on. Webmin consists of a simple web server, and a number of CGI programs which directly update system files like /etc/inetd.conf and /etc/passwd. The web server and all CGI programs are written in Perl version 5, and use no non-standard Perl modules.
