About
Christian, husband, father, and fascinated with IP networking and security.
I've been in the IT and Networking field since 1989 and can honestly say I think I've seen it all.
[Waxing nostalgic] I held a Novell CNA when that was the in certification and can remember building my first Novell ELS Level I server. I stopped working with Novell when it went into the 5.x chain (After having built more than 500 different servers from v2.2, v3.12, and v4.1). That was when I jumped into –on the server side - Windows NT 3.1 and worked with Windows Server OSs until stopping with Windows 2003. I've also had a long history in the *nix world. I first delved into this world with SCO Xenix - albeit lightly - as a bootp server for Terminal Servers. I've also worked lightly with IBM AIX - but, today, I work mostly with Linux - primarily RedHat flavors.
As to hardware - I first started networking with IBM PC Network running at a whopping 2Mb/s - Whoo Hoo what a rush!!! Then I graduated to Token Ring and doubled that to 4Mb/s and soon after quadrupled to 16Mb/s. (Anyone remember putting together Type 1 connectors? Lots of fun… not!) Then on to 10Base-2 (missed the whole 10Base-5 vampire taps - Thank God) But 10Base-2 wasn't all that great either with one loose T-connector bringing down the whole network. (Arggg) Then the networking savior had finally come: 10Base-T followed by 100Base-T!!. Now GigE is the de-facto norm and, in the provider world that I now work, PPP T1s up to 10G is everyday work for me.
I first got into routing with Novell IPX/SPX (which was an experience), then with NetBIOS (which was worse than IPX/SPX), then (finally): IP. Wonderful IP. And here I am: If it's IP, I'm routing it, policing it, filtering it, inspecting it, tracking it, reporting on it, putting voice on it, securing it, and generally just enjoying working with it.
