Netzwerkadministratoren 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.

    I can't access my websites from my network. I have 2 servers which I am hosting my websites from my home. I was able to access both with my public and private IP. Since last week I did install bigbluebutton on one server the strange thing here is that I can't access my website of Bigbluebutton from my network. I have to use a VPN to be able to access the website. The other server I was hosting also 2 sites on it. I start to use the Nginx as a proxy for the other 2 websites on the second server because of limited ssh 443. Now I can access those websites which I was able to access before from my network, I can only access them also from a VPN. I want to solve these issues
