  1. edit: /etc/hosts
127.0.0.1 srv03.mil1.wide-net.org localhost.localdomain localhost

  1. edit: /etc/sysconfig/network HOSTNAME=srv03.mil11.wide-net.org

  2. past into kernel new hostname echo "srv03.mil1.wide-net.org" > /proc/sys/kernel/hostname

Or

sysctl kernel.hostname=srv03.mil1.wide-net.org

Consider a restart net services /etc/init.d/network restart but is not strictly required.

  1. Edit: /etc/sysconfig/network

And append following line, to enable in systemwide the ipv6 protocol:

NETWORKING_IPV6=yes

  1. Edit: /etc/sysconfig/network-scripts/ifcfg-eth1 (or your interface number)

And append following line, to enable ipv6 on interface and the address/gateway if you use static routing:

IPV6INIT=yes
IPV6ADDR=2001:1418:0193:000B::210
IPV6_DEFAULTGW=2001:1418:0193:000B::251

Save, close and restart network service:

# service network restart

Partiamo dal indicare che ufficialmente CentOS nei sui repository non ha i pacchetti di asterisk, quindi è necessario utilizzarne degli altri, in particolare quelli di Trixbox che come ben sapere è basata su questa distribuzione.

Per primo, installare il plug-in che ci permette di gestire le priorità

[root@server ~]# yum install yum-priorities

Creare un file con il seguente contenuto e posizionarlo in /etc/yum.repos.d/ nominandolo con estensione .repo

[trixbox\]
name=Trixbox - Repo
baseurl=http://yum.trixbox.org/centos/5/RPMS/
gpgcheck=0
priority=2
enabled=1

A questo punto è necessario inserire il campo “priority=1” negli altri .repo presenti nella directory e procedere con l’installazione di asterisk soddisfando le dipendenze relative ad esso con il repository di Trixbox per evitare incompatibilità.
