Linux / UNIX / FreeBSD Systems Administrator
I am a full-time Systems and Network Administrator and have been for 28 years. After all this time, I still get excited when I login on a system shell and I still love a good challenge. Most of my career has been spent working for Internet Service Providers but I also work with smaller companies and non-profit organizations. If you don't see it listed below, I've probably still worked on it but these are the things I love and deal with on a daily basis:
? Linux (Ubuntu, Debian, Centos)
? FreeBSD
? pfSense
? Solaris
? Bourne Shell, C shell, T shell, Bash, and Shell scripting
? Apache
? Bind / DNS
? DHCP, FreeRadius
? Postfix / Sendmail / Qmail
? tcpdump, Wireshark, snort, and other sniffers and IDS/IPS solutions
? Nagios 3 and 4
? PRTG (windows only)
? MRTG / RRDTool
? Cisco Switch and Routers
? MacOS
? Apple MDM Management Solutions
