Διαχείριση Δικτύου Jobs

Any organization with an online presence wants to ensure that this presence is seamless, and that users and customers can constantly access their website for information, or to purchase goods and services. A network administrator ensures that this technical support is solid, and works to quickly resolve any potential issues within the network, to make sure that all systems are a go when it comes to the organization.


This often includes testing the network for weaknesses, which could lead to resolving more deep-seeded technical issues that could have been lethal to the company’s growth. It also includes utilizing specific e-mail and internet filters to protect the organization from outside threats of all kinds, and ensuring that the company’s network is updated in every sense possible.

 

A network administrator’s role can be very different, depending on the organization, but almost always requires a diligent eye and a pro-active attitude when it comes to protecting the security and productivity of a company or organization. The position requires a tremendous amount of technical knowledge, and without network administrators, organizations would be susceptible to more attacks, and have much less network resilience, which is essential in terms of overall productivity.

    Set up an OpenVPN server with a firewall that works as follows: There must be administrators who are allowed access to all nodes. There should be pools of different sites, and nodes included in them, each of which has its own VPN certificate and VPN address. Within these pools, access between nodes is open but can be restricted if needed. There are also companies that can combine pools of several sites. In other cases, there is no direct connection between the pools of different sites. Pools of organizations and their nodes should be pulled automatically from the JSON file, and the rights to the pool should be automatically issued to the node based on the contents of this file, while administrators, as mentioned, should always have access to all nodes.

    I don't know if it is possible at all, but maybe there are some tools or other methods ... I shop at some online store. Items are added once a week at the same time. The server is then so overloaded that it takes several dozen or even hundreds of attempts to load the website and it takes up to 30 minutes. I'm looking for some way to make this connection run more smoothly. I am not the owner of this shop. I am a user. If you are interested I will send you the address of this store to check your ideas.
