This Quagga Tutorial just I write to complete Quagga Tutorial post before. Quagga is an open source routing software based on Zebra router. It’s supports the main routing protocols such as RIP, OSPF or BGP

Also in this Quagga Tutorial I will tell you that Quagga can be installed on any Linux system with a 2.4 or higher kernel. Quagga is composed of several daemons, one per routing protocol and another one called Zebra acting as the kernel routing manager. Each daemon has its own configuration file and terminal interface which can be accessed by telnet. The vtysh tool is provided to configure the Quagga router from the localhost, in a unique interface. See the Quagga tutorial for instructions on configuring the router.

Quagga works independently from the operational system (OS) over which it is installed. It must be emphasised in this Quagga Tutorial, that Quagga owns only routing capabililies and functionalities associated with it, such as access lists or route maps. It does not provide “non-routing” functionalities such as DHCP server, NTP server/client or ssh access but it is often possible to enable them on the operating system supporting your Quagga router.

Definiton

Portknocking is one method in network security used to open a closed port or open access to firewall and permit knocker enter into port by passing selected packet to selected server/firewall.

The Methode

• use the key coats combination to protect a communications port.

• Key of knocking port system is itself communications ports. The way to open the key is by accessing designedly some communications ports that truely closed.

• When some communications ports accessed with selected combination, will open a new communications port and you are free to enter.

• For example, to open the port 22 ( communications port for remote login application SSH ), you must “knock” port of 450, 360, 270, 180. When you enter correct combination in a selected time, port 22 will open like you wish

The advantages

Portknocking good for computer user often work outside or network and server administrator to managing server 24 hour everywhere. Port Knocking is remarkable method as a road access to peripherals of their computer.

Port knocking suited for the them that still wish to strengthen the computer security system and peripheral of his network, while still have personal communication into the system and can be done from everywhere.

Personal communications means connection the unopenness generally like SMTP or HTTP. Usually this personal communications have the administrative character and use the services like telnet, SSH, FTP, TFTP, and etc. This Personal communications will be dangerous if done by the others people with no previllege. By using Port knocking, the services will fixed closed to be accessed by public, but can opening by whom which have the combination knock of his port. Read the rest of this entry »

IPV6 have fitures and the advantages is not had by IPv4.Some fitur is:

Multicast : more flexible than broadcast, give ability to deliver a group of host. One of the application is to broadcasting video to a group of user able to be distributed passing some site.

Anycast : give ability to deliver to a group accepting is member (node) one of the group proximate, if failure will be delivered to other node which is his distance relative close to before node and so on.

Path MTU Discovery : make host to study the maximum package measureable to be delivered without existence of fragmentation so that will improve the transmission efficiency.

In this time Internet put hand to the bases best efforts and quality of service (QoS) most outside conducting user. But User commercial from Internet take example company, will improve requirement of guarantee of quality of service (QoS) for all their traffic or at parts of selected traffic.

Without existence of improvement and election of quality, service like Internet Telephony and the video that require minimize selected quality of service (QoS) will cannot is possibly executed. Requirement of the quality of service like our desire that everyone can access our webpage swiftly, desire that our internet telephony work by way of having the maximum warranty delay transit. Other requirement take an example you wish to guarantee the existence of priority to traffic mail or other when your network is the network have the big files and user access from FTP. Or you wish to do Broadcast Video (VoD) but this traffic do not want to be disturb by other traffic.

IETF specification of approach (service integrated and separate service) to provide the warranty and election of service quality (QoS) traffic through Internet. Like IPSEC, this approach can also implementation at IPv4, but the implementation at IPv4 product don’t be like when implementation at IPv6 product. Don’t be like IPSEC, implementation QoS to IPv4 will get functions from QoS slimmer compared to the implementation at IPv6. This matter because IPv6 enter the flow lable field accurately permiting flow of traffic distinguishable, which make possibility to identify presisily traffic requiring selected quality of service (QoS).

IPv6 is abbreviation of Internet Protocol Version 6 ( IP version 6, number of 6 here related the version number given, that is version of 6). IPv6 sometime also referred with Next Generation Internet Protocol (IPng). Ipv6 this have been recommended by director Area IPng from Internet Engineering Task Force ( IETF) when IETF meeting at 25 July 1994 like written in RFC 1752, with entitle The Recommendation for the IP Next Generation Protocol. This recommendation have been agreed by Internet Engineering Steering Group and made standart proposal at 17 November 1994.

IPv6 which design by IETF used to change the version IP (Internet Protocol) in this time that is IP version of 4 ( IPv4). Most of all or can be told all user Internet in this time use Ipv4. Ipv4 have proven delay during the time, but there are problem to Ipv4 this, especially at allocation IP.. Referring to on the wane of address Ipv4 the availableness, hence required the new mechanism to be added to Internet.

IPv6 have address length 128bit is while address length of IPv4 is only 32bit. IPv6 improve;repair a number of internal issues IPv4, like limitation of address allocation IP which be available in IPv4. IPv6 also add a number of growths from IPv4 like routing and autokonfigurati on network. Ipv6 expected step by step replace IPv4.

If we talk about networking, usually the topic is Ethernet networking. Ethernet networking work with method that called CSMA/CD ( Carrier Sense Multiple Accees with Collision Detection). The rule of CSMA/CD like following :

1. Computer will check are there using the cable in network  carrier sense).
2. If exist, computer will await shall nothing like computer using the cable in network.
3. When have nothing that use the cable in network, computer soon will deliver the data through network cable.
4. If at the same time, other computer actually also send data, there will be the collision that make data from both computer destroy or fall to pieces. This condition which named as Collision.
5. If actually collision, computer will await within at random and try to deliver his data again until succeed.

So, the conclusion is at one moment, only one computer delivering the data and other computer must be waiting. This occurence which make more and more computer in network hub automatically will progressively make the inefficient and slowly network. CSMA/CD work with half duplex, it’s mean only one  appliance can “converse” at one time

A trackback allows a connection to your blog can be saved, as a comment on another blog. For example, if one of your readers writes in one of your messages, it can also be a trackback to your body. In this case, your blog a comment with an excerpt from their posts and a link to it.

Why should I use trackback?

Link to other blogs is good for your readers and a good thing to do to other bloggers. You know that your readers as well as deputies, and I do not know all bloggers, in turn ties. However, additional functionality trackback in his blog that the connections are not available.

• It is difficult for bloggers to find out what connections between them. Trackbacks blogger can help you along with your blog, and after all, what specifically in relation to.
• Trackbacks Blogger your comments and continue the conversation if desired.
• Trackbacks a comment on the blog, and most bloggers appreciate the interior of the observer.
• Trackbacks enable readers of blogs, in connection with easy reach their site and read your take on the subject.

Enable trackbacks on your blog

If you’re using WordPress, then it’s simple. Log in to your administrator panel (I give an example for Wordpress 2.5.1). Under Settings > Discussion, you should see a check box labeled Allow link notifications from other blogs (pingbacks and trackbacks.) Make sure the box is checked.

How can I trackback to another’s blog?

In your Write a Post, you should have a block labeled trackbacks. To send a trackback to another blog, insert the post URL in that block. Don’t insert the blog’s home page URL; the address has to be one for a specific post so it will put it in the appropriate comments.

It may or may not, contains a summary and photos of more recent contributions. But those summaries (thus Rich Site Summary) allow the user Skim the articles so that they could contribute to a later stage, if they want to access the website source.

The benefits of RSS

RSS gives benefits to both readers (users) and web publishers. I give example some Popular Blog, this one Johnchow,Budi Rahardjo,Problogger,Kombor or Cosaaranda, they provide RSS facility. So, because Popular blog, they have many RSS reader. Some benefit like following;

• It provides the latest updates.
• It saves time to browse.
• Can be used as advertising or marketing tool.
• It’s spam-free. Unlike e-mail subscriptions, RSS not use your e-mail address to send updates thus your privacy remains safe from spam messages.

The weakness of RSS

• Most readers prefer even a series of changes in a brief summary of entry, making them more access to the site.
• Some people prefer e-mail updates an RSS feed.
• RSS create more traffic and demands on the server.
• Graphics and photos are not at all feeds.
• The identity of the source site can lead to confusion. Since RSS feeds, not the URL or name of the site, can sometimes be confusing what the diet is really a user to read.
• Publishers can not determine how many visitors are responsible for nutrition and frequency of their visits. In addition, there are reasons that end users who have an important role in improving their advertising.

How I begin to better RSS?

There are two things needed: an RSS feed and an RSS aggregator or reader. The RSS-Feed RSS comes from a site support. There are also websites which contains a list of feeds from different Web sites. An RSS aggregator is used to read RSS feeds source Web site. Collects and analyzes the latest data on feeds on the Internet in the world.

An aggregator comes in two forms: a downloadable program also known as an aggregator line and desktop or Web-based aggregator. Downloadable aggregator may require payment before being purchased during Internet-based aggregators are usually free. All you have to do an account, then you’re ready to use their services. Both versions, you can modify, or select the RSS feeds. Aggrégats paid are generally chosen for more experienced users, and they tend, for greater freedom in customizing feeds.

• Choose an RSS aggregator. For starters, Web-based Aggrégats is recommended, because they are usually easy to use.
• Analyse the homepage of its website, the goal for the RSS or XML button. This includes RSS code is necessary to define the concept of the aggregator. Copy this code. Syndicate offers a directory of websites, RSS feeds.
• Insert the code (which contains the site URL) in your aggregator. It is a space to insert the code.

After these three simple steps, you can start by reading RSS feeds from the Internet. The new messages appear in the form to be issued in real time on the website source.
