Network Administration 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.

    Hi, I have both vCenter and ESXi hosts on latest versions. But since beginning one ping fails every now and then. Sometimes every couple of minutes more or less than other times. Each VM including vCenter, each host miss one ping at different times.

However if I am not wrong I have seen pings missing even on single host right after it's installation so I mean without even distributed switches, kernels, nics etc... configured even and still missed ping issue was there.

    We have an embedded ARM based platform (similar to Raspberry Pi 4) that has been configured as a WiFi router for connecting Apple and Android phones only (no laptops). We need a solution that blocks all apps and internet traffic except for applications we nominate. Initially we want to allow network access for WhatsApp and Email (all email apps) . Our preference is a solution based on executing a script that adds more iptable rules or entries to the dnsmasq or something similar. If we need to add additional software modules, this is not ideal, however it may be necessary. Currently our platform is using Hostapd, dnsmasq, iptables and systemd. The WAN is connected to eth0 and WiFi clients connect to uap0 with iptables and dnsmasq setup to completely block access until connected clients en...
