Duplicity at this month’s meeting

Hi,

The next CPLUG meeting will be on Tuesday, 9/13/2011 at 6:30 PM at ITT in Harrisburg.

This month, Doug will be talking about backups and duplication using Duplicity.

Duplicity (http://duplicity.nongnu.org/) backs directories by producing encrypted tar-format volumes and uploading them to a remote or local file server. Because duplicity uses librsync, the incremental archives are space efficient and only record the parts of files that have changed since the last backup. Because duplicity uses GnuPG to encrypt and/or sign these archives, they will be safe from spying and/or modification by the server.

We’ll be in the same room as last time (Theory 9). Directions and details are on the website: http://cplug.net/wp/meetings/

See you then!

August meeting topic is iptables

The next CPLUG meeting is Tuesday, August 9, 2011 at 6:30 PM at ITT in Harrisburg. This month, Nathan will be presenting a gentle introduction to Linux iptables. What’s iptables you ask?

Quoth Wikipedia: “iptables is a user space application program that allows a system administrator to configure the tables provided by the Linux kernel firewall (implemented as different Netfilter modules) and the chains and rules it stores. Different kernel modules and programs are currently used for different protocols; iptables applies to IPv4, ip6tables to IPv6, arptables to ARP, and ebtables for Ethernet frames.”

It’ll be a good talk for both users new to Linux and users who’ve been using it for a while.

Details on the Meetings page. See you then!

This month’s CPLUG meeting is Tuesday, 7/12 at 6:30 PM at ITT. It’ll be in the same room as last time.

The rest of the meeting will be a general new user info session. If you are new to Linux, bring your questions! If you’ve been using LInux for a while, please come and help provide answers!
