Infrastruttura Wireless presso le Strutture CNR Piemonte (The Wireless infrastructure at Piedmont CNR network)

RT 26; The increasing popularity of laptop computer and the work on mobility requirement are the main reasons to deploy a wireless network infrastructure providing a secure internet connection for local and external users. Wireless network has a lot of benefits but it is necessary take special care with security to prevent intrusions and illegal use of the network. Central administered wireless infrastructure is a good solution for security and it allows an easy maintenance of the access point configuration. The Sonicwall Network Security Appliance NSA-5500 is the core of Piedmont CNR Network Infrastructure and its options regarding wireless LAN allow us to deploy a wireless infrastructure meeting all requirements. The main features of our deployment are: multiple SSID announcement, 802.1x protocol support, captive portal authentication, radius and ldap integration, cross-authentication with local and national organizations

Accesso Wireless Federato presso l'Infrastruttura di Rete CNR Piemonte (Federated Wireless Network Authentication at Piedmont CNR network Infrastructure)

RT 34; The CNR Ceris IT Office was an active subject in the designing phase of IDEM (federated IDEntity Management for service access), the GARR project of the Italian Federation for network authentication and authorization, and has acquired a wide experience in federated services and in the SAML platform. IDEM has now reached a stable production level and the services accessed through our IdP are appreciated by Piedmont CNR users (for example, electronic publications or videoconferencing reservations). To improve our network services we have extended wireless access with federated authentication to simplify user login and mobility among GARR research and educational institutions. The new feature has been developed by Shibboleth open-source software installed on a Linux Ubuntu server and some code in the PHP language, integrated with the Guest Services of the Sonicwall Network Security Appliance NSA-5500 by secure communication over HTTPS and digitally signed messages

KVM: an open-source framework for virtualization

RT 44; This report analyses the configuration steps of the open-source hypervisor component KVM, (Kernelbased Virtual Machine). KVM solution is used for digiBESS (open-source project of digital archive) and all network services as web and application servers, user backup, long term archive and e-mail

GBrowse installation and customization to display the Gigaspora margarita BEG34 mitochondrial genome data

RT 01; The Generic Genome Browser (GBrowse) is a simple but highly configurable web-based genome browser. GBrowse consists in a combination of database, interactive web pages and a rich set of utilities for manipulating and displaying annotations on genomes. The Gbrowse platform has been largely used as visualization tool for most of the model organisms. This tutorial shows how to configure a GBrowse genome browser installation to display the mitochondrial genome annotation of the Arbuscular Mycorrhizal Fungus Gigaspora margarita BEG34

miRVIT: A Novel miRNA Database and Its Application to Uncover Vitis Responses to Flavescence dorée Infection

Micro(mi)RNAs play crucial roles in plant developmental processes and in defense responses to biotic and abiotic stresses. In the last years, many works on small RNAs in grapevine (Vitis spp.) were published, and several conserved and putative novel grapevine-specific miRNAs were identified. In order to reorganize the high quantity of available data, we produced “miRVIT,” the first database of all novel grapevine miRNA candidates characterized so far, and still not deposited in miRBase. To this aim, each miRNA accession was renamed, repositioned in the last version of the grapevine genome, and compared with all the novel and conserved miRNAs detected in grapevine. Conserved and novel miRNAs cataloged in miRVIT were then used for analyzing Vitis vinifera plants infected by Flavescence dorée (FD), one of the most severe phytoplasma diseases affecting grapevine. The analysis of small RNAs from healthy, recovered (plants showing spontaneous and stable remission of symptoms), and FD-infected “Barbera” grapevines showed that FD altered the expression profiles of several miRNAs, including those involved in cell development and photosynthesis, jasmonate signaling, and disease resistance response. The application of miRVIT in a biological context confirmed the effectiveness of the followed approach, especially for the identification of novel miRNA candidates in grapevine. miRVIT database is available at http://mirvit.ipsp.cnr.it.Highlights: The application of the newly produced database of grapevine novel miRNAs to the analysis of plants infected by Flavescence dorée reveals key roles of miRNAs in photosynthesis and jasmonate signaling

Step by step installation guide of a digital preservation infrastructure

The Ceris-CNR project of digital preservation infrastructure has been committed by Bess (Social Science Electronic Library of Piemonte) for years 2011-2012 sponsored by Compagnia di San Paolo of Turin. Ceris-CNR role is to handle all the post-scan of the digitalization, for this purpose it has deployed the software and server platforms of the repository and also the web portal for the presentation, research and consulting. This report is a guide of step by step followed to build the digital archive infrastructure

Storage in HA: manutenzione ordinaria e straordinaria

Ceris-CNR IT Office manages the CNR Piedmont network infrastructure and provides network services for about 420 users. The development of a large and reliable storage system is the answer to two needs: one from users, who must deal with ever more larger digital objects for personal and research use, and one from need to have a space system engineering to store virtual machines and backup copies. To contain expenditure and without detracting from the reliability of the system, we choose to concentrate financial commitment on quality hardware and realize the whole project with open-source software, specifically the main components are: Linux, DRBD (Distributed Replicated Block Device), Corosync and Pacemaker

Repository e front-end open-source per la conservazione di opere digitali

Ceris-CNR IT Office and Ceris-CNR Library are involved in a digitization project promoted by Bess (Electronic Library of Economic and Social Sciences in Piedmont Area) and commissioned to handle all the post-scan of the digitization. This technical report analyzes the strategies adopted and the main open-source software used. Ceris-CNR had to provide for the management of large volumes of data with the availability of space storage for the digitized works with characteristics of stability, versatility and dynamism. Ceris-CNR has deployed the software and server platforms of the repository, in a virtualized and redundant infrastructure. Ceris–CNR also take care of the design, development and management of the web portal (front-end) for the presentation, research and consulting data of the digitalized item
