per prima cosa installare i seguenti packages:

apt-get install nscd libnss-ldap

alle domande che vi verranno fatte rispondete così:

  • LDAP server Uniform Resource Identifier: ldaps://quercia.reti.dist.unige.it
  •  Distinguished name of the search base: dc=reti,dc=dist,dc=unige,dc=it
  •  LDAP version to use: 3
  • Make local root Database admin: Yes
  •  Does the LDAP database require login? No
  • LDAP account for root: cn=admin,dc=reti,dc=dist,dc=unige,dc=it
  • LDAP root account password: ***chiedere a Roberto o Mattteo ***

Adesso si deve modificare il file vim /etc/nsswitch.conf, aggiungendo la parola ldap come qui sotto:

...
passwd: compat ldap group: compat ldap shadow: compat ldap
...

Aggiungere le seguenti linee a /etc/ldap.conf

scope one
pam_filter objectclass=posixaccount
pam_login_attribute uid
pam_member_attribute gid
bind_policy soft
nss_base_passwd ou=People,dc=reti,dc=dist,dc=unige,dc=it?sub
nss_base_passwd ou=machines,dc=reti,dc=dist,dc=unige,dc=it?sub
nss_base_shadow ou=People,dc=reti,dc=dist,dc=unige,dc=it?sub
nss_base_group  ou=group,dc=reti,dc=dist,dc=unige,dc=it?one

 

installiamo anche le ldap-utils:

apt-get install ldap-utils

e modifichiamo il file /etc/ldap/ldap.conf come segue:

#
# LDAP Defaults
#

# See ldap.conf(5) for details
# This file should be world readable but not world writable.

BASE    dc=reti,dc=dist,dc=unige,dc=it
URI     ldaps://quercia.reti.dist.unige.it

TLS_CACERT /etc/ldap/certs/ldap-quercia.crt
TLS_REQCERT never

In /etc/ldap/certs/ dovete copiare il cetificato di quercia (che trovate su quercia nel medesimo percorso)

scp -r user@quercia:/etc/ldap/certs /etc/ldap/

OK tutto a posto, ri-avviate nscd:

service nscd restart

 

 

Summary of contents

The main objective is to give a basic knowledge about the main wireless network technologies, architectures, protocols and standards. Three main areas will be introduced and described: i) the wireless Local/Personal Area Network (W/PLAN) current standard technologies with a hint to the wireless access network; ii) the cellular radio mobile networks (GSM, UMTS, LTE); iii) the mobility management in packet (IP) network.

 

Requirements

The following arguments represents the minimum knowledge required to the students for following the course in an effective way: basic concepts of data networking, circuit and packet switching, functional architectures, ISO OSI architecture, TCP/IP architecture, physical layer main characteristics (cables, optical fiber), data layer basic characteristics, Ethernet/IEEE 802.3 protocol, Layer 2 bridging/switching, IPv4 basic concepts, IP routing basics, TCP/UDP basic knowledge.

 

Through this website section students can access to a number of teaching services and resources made available by Prof. Bolla and the TNT Lab.

In particular, students can:

The Telecommunication Networks and Telematics (TNT) Lab. is a joint research laboratory between the DITEN at the University of Genoa, and the National Inter-University Consortium for Telecommunications (CNIT). Its staff is composed by Prof. Raffaele Bolla (head of the TNT Lab.), Prof. Franco Davoli, two CNIT scientists (Roberto Bruschi and Matteo Repetto), a Post-Doc of the Universty of Genoa (Riccardo Rapuzzi) and 11 further persons among Ph.D. students, research fellows, and highly specialized engineers.

The main research topic addressed by the TNT Lab is in the field of the “Future Internet” and related technologies. In this respect, the latest specific research efforts undertaken by the TNT Lab regard: Energy-efficiency in ICT, Green Networking, Smart Grid, Distributed Router Architectures, Multi-core Linux SW Routers, Monitoring, Traffic and Network Models, Planning and Control Mechanisms, Network processors and custom smart boards; Continuous and cross-ambient communications, Ad hoc Networks, Vehicular Traffic Estimation through Mobile Networks, Mobility Management.

The TNT Lab is the center of a number of research initiatives and projects funded by national and international industries and industrial fora (GeSI), standardization bodies (ITU-T), the European Commission, and the Italian government. The TNT Lab research heads are principal investigators in many of these research projects (among the most recent ones we can cite the EU FP7 ECONET Integrated Project, of which Prof. R. Bolla is the coordinator and principal investigator, the national “PRIN” project EFFICIENT, coordinated by Prof. F. Davoli, and the GreenNet “FIRB-young researchers” project, coordinated by Dr. R. Bruschi).

The general research approach aims at covering the complete cycle of the research and innovation process: the staff activities starts from measurement campaigns on real network infrastructures of device prototypes, go through the design of theoretical models and optimization mechanisms, and arrive to the realization of in-house prototypes. To this purpose, the laboratory is equipped with professional instrumentation (among others, 3 router testers, 10 SW routers, Netlogic and Intel network processor evaluation boards, remote watt-meters, high precision multimeters and DAQs, OpenFlow switches, etc.).

Through this website section, reseved to the TNT Lab staff, you can access to different services, like:
