Top 5 Open Source Firewall


1) IPTable 


User, which allows a system administrator to configure the tables provided by the firewall of the Linux kernel (as units executed Netfilter different) rules and chains and stores. And is currently using the kernel modules and different programs for different protocols; iptables applies to IPv4, ip6tables to IPv6, arp tables for the rehabilitation of agriculture, as a special ebtables Ethernet frames

IPtables require elevated privileges to work must be carried out by the root user, but it failed to function. In most Linux systems, iptables is installed as /usr/directory/iptables and documented in the man page to him [2], which can be opened using `man iptables` when installed. Can also be found in the /sbin/iptables, but since iptables is not "dual core", but more like a service, is still the preferred place / usr / Guide



2) IPCop

The IPCop Firewall is a Linux firewall distribution. It is geared towards home and SOHO users. The IPCop web-interface is very user-friendly and makes usage easy.
The (old) information from http://www.ipcop.org can be found here: http://www.ipcop.org/index-pn.php Be aware that most of the information is old and obsolete.
One day there may be a flashy, web-2.0 style homepage, but until then the page you are now reading is the home of IPCop.

    VIM Faster Navigation

    Sometimes even the simplest of tasks like navigating through a single file can be optimized. Vim offers several methods of navigation within a file, which can adapt to the contents of the file and how it is organized. Some of these methods are obvious, while others are more complex. Mostly, the files we are editing are well structured. If our files are text, then this structure can be in the form of paragraphs, sentences, and words, or at other times code with functions, blocks, and code lines. Vim supports jumping around the file, according to the structure in the file, and has key bindings that make it easy to go to the exact place in the file where you want to go. Moving within a text file You are working on a normal text file and in the middle of a sentence you realize that you have forgotten to make the first letter in the paragraphs uppercase. You could of course, use the arrow-keys or the h/j/k/l navigation keys to move to the beginning of the paragraph to cor...

    Typical Oracle RAC configurations

    All configurations are based on the following building blocks: Hardware Server nodes Storage Networking Software Operating system Cluster software Oracle RAC (application) Application architecture Oracle9i RAC on RAW devices is based on a shared disk architecture. Figure 2-1 shows a two-node cluster. The lower solid line is the primary Oracle interconnect, the middle dashed line is the secondary Oracle interconnect. For high availability, both these networks should be defined in the HACMP as "private". HACMP/ESCRM provides Oracle9i RAC with the infrastructure for concurrent access to disks. Although HACMP provides concurrent access and a disk locking mechanism, this mechanism is not used. Oracle, instead, provides its own locking mechanism for concurrent data access, integrity, and consistency. Volume groups are varied on all the nodes, thus ensuring short failover time. This type of concurrent access can only be provided for RAW ...
