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.Contratar a Network Administrators
We are being targeted by an online attacker who sends hundreds of requests to our server every minute. We are not sure if this is a DDOS attack or is it for scraping/data theft or otherwise, but we have a large list of IP addresses, with associated URL's requested, with timestamps. The IP's are (as expected) proxy servers all around the world. We need someone who can track down this attacker and provide us with a (source) IP address (or any other information) regarding this attacker, so we can press legal (or informal) action. Let us know if you can do this.

We need to setup ZTE ZXA10 C300 OLT for multi ISP and IPv6 dual stack OLT is running as router. We need to have distinct default gateway per ISP. I mean that ONT from ISP1 must have internet through ISP 1 router, ONT from ISP2 must have internet through ISP2 router and so on. We need only this for Internet traffic. Management and provision traffic always goes through ISP1. We have tried to setup policy routing and/or vrf but something is missing.
