网络管理 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.

    The Requirement is to change a setting on our building router to allow our VPN not to be blocked as currently, the internet will block our VPN due to not recognising the port request. This should be a simple change but unfortunately the building owner does not have the login details for the router, which is a dray Teck. The way the building’s internet works is that there is a large internet system downstairs – see picture attached, which passes internet throughout the building and for our office we have an ethernet cable which we plug into an office router which is a TP-link AC2300. This is made more complicated by the fact the router is part of a complex system involving 2 dray Teck routers, one of which is a security box that might also be blocking our VPN. There is also a...

    I would need support in setting up a Keycloak User Server and a reverse proxy "in front" like NGNIX for example. Attached is a small sketch: The whole thing should be run on Azure. The clients that arrive via the browser should come to a login page of the Keycloak server and there, based on the user login, it is decided whether it is forwarded to the virtual server 1 or 2 or n (also on port 80/443) furthermore there are direct port (socket connections) which must be decided via the port to which virtual server they are mapped. The whole thing should be expandable, that is, more users and ports simply entry bar. thank you

Just need someone to go over the configuration and see if everything is setup properly. And if it’s ok to demote/turn off the DC1. Existing physical server DC1 had ERP application on it so I have virtualized this DC1. And added it to hyper-V in the new server DC2. I want to just turn off the physical server. So I will have DC2 physical server as our main primary DNS host. And the VM -DC1 will be secondary DNS with the applications. Or vice versa. We can leave VM-DC1 as primary DNS and DC2 as secondary.
