Configured higher security standards for ssl and IPsec vpn configuration for Fortigate and Cisco firewalls.
Configured port forwarding to go through the firewall and to all internal switches for snmp to allow remote monitoring of not only all relevant oid’s on the firewall, but all relevant oid’s on the switches as well. This gave us much faster response times in investigating network problems on remote networks.
Setup a portable odroid network monitoring device that allows remote access into the device while providing network monitoring on all the internals of a client’s network, giving even more depth and understanding to employees at DCANet for a remote client’s internal network, without having to go onsite. Also greatly improved troubleshooting effectiveness.
Identified that having a vlan on the wan interface of a firewall can cause throughput issues on certain firewalls and found the workaround to be installing a switch to take the vlan and put a port on access for the firewall to use.
Audited all networked equipment to be monitored for hardware or security problems such as CPU or bandwidth issues via cacti that could be indicative of hardware, network, or security problems such as denial of service attacks.
Changed switchport mode to access on cisco switches whose connections terminated on cisco sg800-08 switches so that they could be remotely accessed as sg800-08 does not support vlan access.
Thoroughly updated and maintained the DCANet MediaWiki knowledgebase to greatly improve productivity and training.
Set up Cacti network monitoring live graphs to monitor spikes on core network equipment that are indicative of attacks, and made a separate configuration to provide email notifications for those events.
Prioritized VoIP on firewalls, including dual wan configurations, to remove interference and call drops in all network installations.
Created video tutorials for email access for customers.
Upgraded our Barracuda email spam firewall to provide an additional cloud layer of spam filtering and email backup, at no additional cost to DCANet.
Promoted positive and clear communication among engineering and support teams.
Developed several WordPress websites for customers who wanted more modern designs, as well as our own website.
Migrated websites off of our older UNIX and Windows hosting platforms to a newer Linux-based platform.
Upgraded and organized our network monitoring capabilities on Cacti, Nagios, and SmokePing to greatly decrease troubleshooting times.
Created network topography maps for non-standard network designs for easy access on our knowledgebase.
Refined our network alert system and knowledgebase so that it is more thorough and accurate, to allow fast response times and troubleshooting.
Created a table of contents for our knowledgebase to standardize the organization of any further articles and to ensure that all maintained pages are connected.
Updated SmokePing’s graphical interface, as well as ping interval and alarm times, to record all network disruptions. Multiple threads were used to share the load on the cpu of the server. Configured on Arch Linux and implemented FastCGI for a speedy graphical interface.
Unlocked additional frequencies with Ubiquiti’s assistance in cooperation with the FCC to allow PTP wireless connections to flow unimpeded in congested areas (such as downtown Wilmington)
Mitigated an active cryptovirus that was encrypting all data on a shared drive (all of the customer’s backups were on this drive) and successfully restored that data from damaged and hidden shadow copies via Windows Server 2008 command line.
Set new standards for storage equipment to reduce response times for customers with damaged or misconfigured onsite equipment.
Found that monitoring the last hop before a network connection enters a building allows for quick identification of internal or external problems (don’t have to call the ISP to identify if it’s our problem or theirs).
