Mac Os X: Mount NFS Share / Set an NFS Client

Super ben explicat:


How do I access my enterprise NAS server by mounting NFS filesystem onto my Mac OS X based system using GUI and command line based tools?

NFS (Network File System) is the common for file sharing on NAS server and Linux / UNIX systems like, HP-UX, Solaris, Mac OS X, and others. Mac OS X can be setup as an NFS client to access shared files on the network.

Webmin en Ubuntu Server 10.4 LTS

Instal·lem les llibreries i dependències:

# aptitude -y install perl libnet-ssleay-perl openssl \

libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl \

apt-show-versions libapt-pkg-perl

Si es queixa de libmd5-perl l'haurem d'instal·lar a ma:

Descarregar la versió mes actual des de:

http://ftp.debian.org/pool/main/libm/libmd5-perl/ 

#dpkg -i  libmd5-perl_2.03-1_all.deb

Descarregar el Webmin de http://www.webmin.com

i instal·lar:

# dpkg -i webmin_1.510-2_all.deb

El problema / Complexitat esta en les dependències i que la llibreria libmd5-perl no esta en els repositoris... 

La resta es tot normal, senzill i ràpid.

Guidelines for Numbering IPv6 Point-to-Point Links and Easing the Addressing Plans

http://www.consulintel.euro6ix.org/ietf/draft-palet-v6ops-point2point-00.html

There are different alternatives for numbering IPv6 point-to-point links, and from an operational perspective, they may have different advantages or disadvantages that need to be taken in consideration under the scope of each specific network architecture design.

However, as a general rule, this document suggest the approach of using /64 in order to ensure not only compliance with standards, and consequently facilitate interoperability, but also in order to ensure avoiding possible future issues and simplifying the addressing plans.

The use of /64 also facilitates an easier way for routing the shorter aggregated prefix into the point-to-point link. Consequently it simplifies the "view" of a more unified addressing plan, providing an easier path for following up any issue when operating IPv6 networks.

Implementing IPv6 Addressing and Basic Connectivity

Implementing basic IPv6 connectivity in the Cisco IOS software consists of assigning IPv6 addresses to individual router interfaces. The forwarding of IPv6 traffic can be enabled globally, and Cisco Express Forwarding switching for IPv6 can also be enabled. Basic connectivity can be enhanced by configuring support for AAAA record types in the Domain Name System (DNS) name-to-address and address-to-name lookup processes, and by managing IPv6 neighbor discovery.

This module describes IPv6 addressing and basic IPv6 connectivity tasks.
