Over the past year or two I’ve been more and more interested in Linux. Having to take a class on Linux doesn’t help.
My primary servers for my network are all windows 2003 servers. And I am impressed with windows 2003 and some of the things it can do; I think I’ll be real impressed with windows server 2007. I’ve played with Linux since the days when all it was was a command prompt, at the time I really didn’t appreciate it as much as I should have. At the time, I did like DOS and I admit I still do. However now, I have met the real Linux. Red Hat 7.2 was the first I really started working with as a server… Then Red Hat 8.0 came out, I even bought the bible on it. I dual booted every computer (non server) in my house to Linux. The Wife didn’t like it until she found Kbounce, an additive little game on KDE’s GUI for Linux. Still for her, it wasn’t a desktop, She needed Microsoft Word.
These days, I think if it weren’t for Microsoft Flight simulator I would be done with Windows. No, I’m not anti Microsoft, I even have an unmodded Xbox and as mentioned before love their flight sims. However as a desktop OS I can’t stand windows. Sure, I manage. I’m very fluent with it and can make it do more than most, but the over all power is lacking.
But I’ve never put a production 100% Linux server on line. I’ve run a ‘nix telnet server, once played around with it as an ntp server. I’m good with IPtables and as such I want to use linux often for firewalls. However the simplicity of a Dlink 604+ router( for internal stuff) or a small Cisco (for my servers) can’t be beat. Yet, I maintain one Linux firewall for the sole purpose of being able to maintain a Linux firewall.
Having fought with a new version of sendmail the other night, all night, if finally clicked and I like it, I’ve never liked sendmail. I’ve decided to put a Linux box in full production. For now, I’m still playing with it but I’ve got a older backup server running a website, NTP, nntp, mail and other services for a small segment of my network and remote clients. All public services are on the internet available for anyone that knows where they are.
In the next six months or so I’ll be migrating one of my primary servers over to Linux. However to do so I need a transition server, one I can put one of my primary server’s work load on until the new Linux server is up and running. For those that don’t know; At this location I have one really, really, nice HP server another really good server and several supporting servers. Most of these are desktop computers that I’ve taken and modded to do (and look) the way I want, aside from the HP which runs most of my public websites and services.
I do intend to convert the HP over to ‘nix, after I get things up on a backup cluster.
Anyway. Last night I fought with Linux on my laptop. Didn’t work. The network card and wireless card aren’t compatible. I’ll have to find the drivers and try again another time.
My main two servers keep to less than five minutes of down time per month. Usually it’ll go three months without down time and that’s when I install a new security patch. My biggest fail potential for this location is Internet connection. It doesn’t happen often but it does happen once or twice a year. Since being with my new ISP I’ve had one ten minute interruption in six months.
Still, plan for things. I always host my mail off site and I have a zoneedit.com redundant DNS servers in case my network goes down, zoneedit will keep the DNS up and as such my mail stays up. Zoneedit has separate locations so they are almost never down, my mail service also has separate locations.
hmm, when I started, this was about linux and thus it shall return. I’ve decided I’m going to work toward my Red Hat Certification. Not going to be easy though.
