Certified professionals get better jobs!

Where do I start? - Degree or Certification

This is a big question in the field of networking and IT in general - should I get a bachelor's degree or have a certification? The answer to this question comes down to your personal preferences and circumstances.

I think both options are important - the university degree provides more general knowledge about various fields of information technology. The certifications provide practical knowledge oriented to certain specific technologies. That's why getting a certification - whether it's a vendor-specific certification such as Microsoft or Cisco, or a neutral one, like CompTIA - is so important to any industry professional. However, I would say that certification is more relevant to this particular field.

Get real-world experience

The number one factor of achieving and advancing in a career like network engineering is practical experience. There is nothing like this. Experience working with networks of different types, technologies and manufacturers is an experience. To obtain a good job, experience is a very valuable factor, but it can be difficult to obtain experience without having a job before, and it is precisely the job that you need to be able to experience.

To solve this egg and chicken problem, my recommendation is to apply for a junior network engineer post or something similar. The objective is to invest a prudent time in order to accumulate practical experience that allows you then apply to higher positions within the organization. The money will come later later.

Get certifications

Another good advice on how to become a network engineer is getting a certification in the field. Several companies offer these certifications and the main companies are Cisco, Microsoft and CompTIA. The Cisco CCNA (Cisco Certified Network Associate) certification is highly recognized. Having the Cisco CCNA certification combined with some accumulated experience in the real world is a very profitable combination for IT professionals. Microsoft also offers different certifications such as: MCITP (Microsoft Certified IT Professional) or MCTS (Microsoft Certified Technology Specialist). CompTIA Network + is a neutral provider certification of the networking industry.

The certifications provide professionals with a great knowledge in the field of network engineering, and it will give a great boost when looking for a job - employers love to hire certified professionals with experience. If you do not have experience, certifications are a great way to start opening up in the labor market.

Develop other types of skills

The final advice to become a network engineer is to work continuously to develop your social skills, those skills that are not technical. These skills will enable you to cope in whatever role you have to play through your professional life and help you stand out from the crowd of gene and in the industry. Skills such as: communication, negotiation, problem solving, professionalism, time management and other personal skills will help you in interviews, at work, getting promotions, and finally to a better financial future!

Benefits of customizing your router configuration

Formerly, the Internet connection was made through modems that through a telephone call established a connection to the Internet, but for some years now, all the companies have started to establish the ADSL or cable lines in a standard way and with them the routers as a connection device.

The benefits of having a router are many, among which we would highlight, the ability to host more number of computers, tablets or phones connected simultaneously among other things and precisely, one of the most interesting features of the routers, is the one that we are going to explain below: The benefits of customizing the configuration.

The routers, come from the factory configured to be plugged in and without having to do anything work perfectly, but this is a bit limited if we are curious with our Internet connection and we want to implement certain aspects such as: Mount a web server or ftp, access our computer from outside the home safely, play online games, change the wifi password, download Torrent or Emule ... and endless configurations that we can touch once inside the router. Enterprise router is a basic product for any business/enterprise.

Normally, to access the router, it is only necessary to type the ip of our gateway or router normally an ip finished in 1 xxx1 and then the access password, which should come in the instruction book or in the router documentation , once inside we can access the following configurations, as long as the router allows it:

Wifi settings : Change the name, password, devices that can be connected and those that can not.
DHCP server : To give or not the ip automatically or require that it be configured manually.
Open or close ports : This is what gives more play within our router because with this we can layer programs or access without the need for a firewall or third-party software or allow access to programs such as the Emule.
Configure ips : We can also change the ips ranges for more security, activate or deactivate dhcp, etc.

These and many more are the benefits of customizing the configuration of your router because today, the Internet provider companies automate these configurations and are exposed to leaks of the algorithm, which will allow a ready outside our network to access our data or simply to use our Internet connection. If you really want to optimize your connection and have a unique configuration, we invite you to change the factory configuration of your router, and if you need help, we help you customize your router.

Do not you get a fixed position? Learn about the benefits of temporary work

Temporary hiring is an opportunity for companies, since it provides them with a customized solution, without the need to authorize increases in personnel or generate employment contracts.

Given the context, candidates are more flexible to take this type of work commitments, because it allows them to remain active in the market and continue gaining experience in new areas, areas and systems of work.

According to data from Robert Half , temporary or temporary services are a real option to reach the professionals needed by companies or for them to continue developing their careers.

In the case of temporary hiring, the evaluation criteria are simpler and more direct. The employer focuses mainly on the ability of the professional to solve the specific problem and for which he was hired, in his work performance associated with that objective and in compliance with the company's labor regulations. This is where the employee must be smart and define his strategy.

Is it possible to grow within the company with a temporary contract?

The analysts assure that, through a temporary contract, it is possible for the professional to stay in the company. Therefore, it must be able to demonstrate its value within a short period of time so that the company ends up deciding to hire it permanently. In this sense, it is recommended:

Act in an integral way.

To show oneself, without trying to pretend something that is not.

Comply with the standards designated by the firm.

Respect hierarchy levels.

Relate to co-workers within the company and make themselves visible, but in a natural way and linked to the success of the work, not trying to stand out from their peers.

In addition, as pink data you should know that approximately 20% of professionals who have a temporary contract ends up staying in the company.

Sectors that bet more on temporary work

The Contingent Employment is well transversal to all sectors, but some of those characterized by incorporating more professionals in this modality are:

Retail

5 advantages of being freelance

Advantages to being freelance

Is true that the pressure on self-employed or Contingent Employment workers is much higher than that of workers employed by: Your customers are not fixed (with few exceptions), have to walk always in search of new business opportunities, do not have paid holidays and the fees and expenses are certainly high.

However, the self-employed, enjoy many advantages that, without hesitation or a second, the adventure of being freelance is worth being lived.

Inter-VLAN routing - ROUTER ON A STICK

The ROUTER ON A STICK is one of the two most common possibilities for inter-VLAN routing.

It consists in creating sub interfaces in a single physical interface of a router.

We have with this configuration the possibility of using a single interface to route the packets of several VLANs that travel through the trunk port of a switch connected to that interface. Enterprise routers are basic product for any business/enterprise.

Do not you know what a TRUNK is? Click here

We can thus configure several IPs of different networks to several virtual interfaces (sub-interfaces) housed in a single physical interface.

We left a bit of the basic routing, which is generally what we learn first, and has a single network connected to each router interface.

Advantages of ROUTER ON A STICK

Easy to implement, it is only necessary to create a subinterface for each VLAN in the Router.

Much cheaper than having a router per VLAN .

Much better latency than having one Router per VLAN .

Routers: how does it work and which model to choose?

In the 21st century, there is a tendency to erroneously classify in the "router" category any box connected live on the Net (typically the "Internet boxes", but not only). Yet, from a technical point of view, it's much more than that. We will try to separate the towels and towels to better navigate.

As we have discovered in the IPv6 folder , the Internet is composed of routers that play hot potato with your IPv4 packets full of your precious data. And this little game, they are rather effective and usually manage to direct the good potato to the right person, that is to say the computer to which the package is intended.

This package is marked "for Caffeine", I do not know the way to his machine, hop I take the path by default
This package is marked "for Faskil", I know the road that goes well to his machine, en route!

And a router, that's just that. Only that. All the time.

Clearly, the router only transmits data packets from one point to another, without being interested in their content. Suddenly, it's ultimately stupid and that's why we regularly say that in the structure of the Internet, it is not the trunk of the network that provides the intelligence, it is the leaves.

And the Internet box was ...

Even if one tends to qualify any Internet router box, it is actually closer to a firewall than a simple router, a firewall is de facto a router, but with more intelligence. To really understand the difference between the two, just remember this: the router is only concerned with the destination address where to send the data packet, where the firewall will take a closer look at the packet and get a feel for it. few more questions about it. Enterprise routers are basic product for any business/enterprise.

Who is the sender? Depending on the sender, we can accept or reject the package.
Who is the recipient? In the same way as for the sender, we can accept or refuse the package depending on the recipient.
What is the application (the port, in technical terms) that is used? You can also block access to certain applications (ports) such as the web server (port 80).

And of course, we can also use combinations of these conditions:

If it comes from Faskil and it must go to Caffeine HTTP (port 80), accept.
If it comes from Mr. Pirate and it must go to Caffeine HTTP (port 80), refuse.

It looks pretty simple like that, except that we are quickly confronted with a little problem: we do not really know how to identify Faskil and Mr. Pirate in the story, they will just be IP addresses. If we know Faskil, and if his ISP provides him a fixed IP, we can reasonably write the rule 1. On the other hand, as we do not know the IP of Mr. Pirate (and it's a little complicated to ask him) , we will have trouble writing rule 2. The scope of a firewall is limited to IP protocols, which is certainly a bit limited, but still allows to do a lot of things.

In addition, all firewalls (to my knowledge) are able to do NAT , as seen in the IPv6 folder. They can therefore match a single public external address visible on the Internet to all the addresses of a private network. On the other hand, a simple router can not.

Suddenly, an Internet box and routers consumer is what?

Whatever your ISP, an Internet box is a firewall, although very basic, but a firewall despite everything. In the same way, any Wi-Fi "router" is also a firewall. Be careful not to confuse what marketing calls "Wi-Fi router" and "Wi-Fi access point", it's not the same thing. The commercial Wi-Fi router is actually a firewall, quite similar in its features with an Internet box. Access points are much more basic, and if they sometimes offer a DHCP server, they rarely integrate a firewall, even simple.

The term "Wi-Fi router" is, as I pointed out at the beginning of the file, an abuse of language. To be correct, we should rather talk about firewall / Wi-Fi router. Yes, I pinch if I want.

Box FAI or "router / firewall" of the trade, it is necessary to choose

For 90% of users, the features offered by the Internet box provided by ISPs will suffice. But we are on Geekzone, and "power users" requires, these devices will not necessarily be enough for our advanced uses. The recurring problem of these devices is an area of reception Wi-Fi at best average, or using outdated standards. It evolves , but slowly, and the duration of exploitation of these products makes the return of the problem inevitable in the medium term.

The other potential concern comes from the absence of advanced firewalling options, or simply an old network switch (blocked at 10 / 100MB instead of gigabit), which can play a great deal on the speed of transfer of video. tata Janine in 1080p DTS on your network. Let's take a look at the solutions that exist on the market ...

Wi-Fi turbo boost

There are several ways to improve or replace Wi-Fi in a box.

1. The Wi-Fi repeater

This solution is the simplest to implement in terms of structural needs, but it is unfortunately not necessarily the most effective. Indeed, the repeater connects to your box in Wi-Fi to provide you with a more effective signal. It is imperative that this repeater is placed in the Wi-Fi zone of influence of the box in question, but not too close because it is a little stupid, but not too far either because it will not work ...

The example above is very telling: the repeater is placed at the blue zone limit, so with a weak reference signal. The "repetition" of the signal will not be really optimal.

The other important point to watch with this kind of devices is the choice of the Wi-Fi channel. You should know that the 2.4 GHz band offers a choice of 14 channels, and it is obviously better not to cross the streams. : if all the Wi-Fi kiosks are on channel 2, it's obviously going to work less well.

Unfortunately, it is not always possible to modify this channel on the boxes of our ISPs. And sometimes, the repeater (especially if it is cheap) does not propose it either. So choose a repeater that offers this option, and use a tool (like Wifi Analyzer on Android) to list the channels already used in your home. Once these valuable information is in hand, make some adjustments:

if your box is on channel 2, set the repeater on channel 8 (far, what)
if your neighbors are equipped with Wi-Fi too, try using a relatively free channel

This will limit the case, but your connection will be very dependent on the quality of the Wi-Fi connection between the box and the repeater (spoiler alert: in general, it does not work very well, unless you directly attach the repeater to the box).

Price: between 20 and 40 euros, some models offering in addition to recover if necessary the network via an Ethernet cable, similar to what we will see in the next point.
