Linux NetFilter, IP Tables and Conntrack Diagrams

IPTABLES TABLES and CHAINS

IPTables has the following 4 built-in tables.

1) Filter Table

Filter is default table for iptables. So, if you don’t define you own table, you’ll be using filter table. Iptables’s filter table has the following built-in chains.

# Importer une clé
gpg --import [filename]

# Rechercher une clé depuis serveur distant
gpg --keyserver pgp.mit.edu --search-keys KEYID

# Importer une clé depuis un serveur distant
gpg --keyserver pgp.mit.edu --recv-keys KEYID

# Exporter une clé sur un serveur distant

Exploit for Samba vulnerabilty (CVE-2015-0240) by sleepya

The exploit only targets vulnerable x86 smbd <3.6.24 which 'creds' is controlled by 
ReferentID field of PrimaryName (ServerName). That means '_talloc_zero()'
in libtalloc does not write a value on 'creds' address.

Linux Backup Solutions

I've been looking for the best Linux backup system, and also reading lots of HN comments.

Instead of putting pros and cons of every backup system I'll just list some deal-breakers which would disqualify them.

Also I would like that you, the HN community, would add more deal breakers for these or other backup systems if you know some more and at the same time, if you have data to disprove some of the deal-breakers listed here (benchmarks, info about something being true for older releases but is fixed on newer releases), please share it so that I can edit this list accordingly.

• It has a lot of management overhead and that's a problem if you don't have time for a full time backup administrator.
