Fedora Core 3 Review

This review is late, to put it mildly, but as they say better
late than never?

I recently installed Fedora Core 3 and have been very satisfied
with it.

Actually to be more correct I "upgraded" to it on a home
firewall machine. This machine has been running iptables and
Red Hat 7.3 (kern 2.4) for *years*. It also runs Sendmail,
BIND, Samba and NTP for the home network. It runs Samba on a
software RAID volume for a type of poor mans NAS (yeah even
poorer than NFS). Other home machines (Linux, Mac, Windows)
mount "my_documents" via SMB and have directories for various
users (and the firewall has backup capabilities via simple
handwritten bash scripts that make and roll backups using tar).

So I finally decided to upgrade. I have used Fedora Core 2 at
the office for quite some time now but have not yet used Core
3. I wanted to start running it at home in preparation for
upgrades on more important machines.

I fully expected to have to wipe the volumes and "install"
rather than "upgrade" as in the past I have never been very
successful with Red Hat/Fedora "upgrades". This time that was
NOT the case, the upgrade was SEAMLESS and everything worked
after the first restart. It was truly a *very* trivial
upgrade.

After the upgrade process completed all previous services were
running and even the firewall script (also a custom hand
written script) ran properly.

I then did the Fedora updates via Up2Date just to see how well
that works. I do not normally use Up2Date and rather hit the
updates FTP site on my own and grab the updates contents and
manually install. Up2Date worked like a champ as well. Things
went eerily well.

I dont use a GUI desktop on the firebox but usually have X and
KDE installed just to play with it. I fired up X and it also
worked flawlessly. The KDE 3.3 stuff is super sweet (I havent
used KDE in a while) and it *felt* very solid and professional.

Every damn thing I tried worked.

Granted I dont really push the machine and the hardware is
pretty simple (standard mobo, IDE drives, Intel net cards, ATI
vid card, nothing special, no firewire driven Digital cameras
and so on ;) but even so most computer OS installations,
especially upgrades, of ANY flavor, dont go nearly as well as
Fedora Core 3 (even previous versions of Red Hat and Fedora).

Props AGAIN to all of the Linux and Fedora community, great
software.   http://fedora.redhat.com

And Konq 3.3 kicks arse too.

RE: Fedora Core 3 Review

So your firewall also runs your file sharing?

RE: Fedora Core 3 Review

Yes it does.

There is actually *another* firewall in front of it in the place of a DSL router/firewall (and the brand/model I have actually is a firewall).

But even if that werent there I would probably stick to this setup to save machines and thus save power.

The machine thats the firewall and fileshare is already on the "inside" but runs iptables as if the DSL internal side is the outside world to it. I do all my port forwards and port blocking and so on from the LINUX machine and then pass it on through the DSL router (which has prett much the default firewall setup from the manufacturer, generic all ports but standard stuff blocked). I generally never have to touch the DSL router (unless I hit a strange port that needs to be tweaked, say to play a game, but then it gets untweaked when done).

Technically I guess its a DMZ type machine but again even if it werent I would still do it on one machine.

I had separate machines at home for several functions, for years, and decided to stop doing that crap to save power.

If the firewall is ever compromised then the intruder will have access to the internal network anyway, sure it would be somewhat safer to have data on a separate machine but ultimately the compromised network could be just as bad.

I have decided (knowingly) that saving power is more important to me than the security of separating the functions.

Also my backup processes burn data to CDs. If the entire machine blows up I can rebuild in a few hours. As for compromise OF the data. Really I dont care about this "data" enough to worry much. Sure its personal files but none have financial info (all online at financial institutions, not local) and none would be very interesting to an intruder, the Christmas letter is great, and all my letters to Congress are fantastic, but just not the sort of stuff I care if anyone gets a hold of. Other stuff includes music files, picture files, so on. I think its fairly well protected anyway, but frankly if it were just public record I wouldnt care. I need the ability to store the data somewhere and have it be reliable (RAID) and backed up much more than I need it to be secure. (In my case.)

RE: Fedora Core 3 Review

Sorry - did not mean to give you grief. Hell I don't even have a backup plan in place yet. I thought about getting a DVD Writer to use that but I'll probably procrastinate that for a few more months.

However I bet the FBI would love to get ahold of those 'letters' to Congress.

RE: Fedora Core 3 Review

np. I didnt take it as grief but as a valid (albeit subtle) point. Its better in situations where you do want real security to have the separate functions physically separate. Thats just not what I need at the house. (Although I did it that way for a long time, I switched as elaborated upon.)

RE: Fedora Core 3 Review

ok, how much power are you really saving?

RE: Fedora Core 3 Review

I wrote the above query? Seriously, is this a measurable dollar amount or one of your tree-hugging ideas?

RE: Fedora Core 3 Review

Well I am not really sure to be honest so for me its more of my tree hugging crap. Yet either way I just didnt feel like I needed multiple machines for this (I have three other rack mount machines composed of hand me down parts in the rack at home right now, in the OFF position).

But lets try to calc.

My elec co charges:

First 500 kWh per month
@$ .0767 per kWh
Next 500 kWh per month
@$ .0736 per kWh
Over 1,000 kWh per month
(For Usage Months October-May)
@$ .0540 per kWh
(For Usage Months June-September)
@$ .0860 per kWh

So we cant just make it simple eh. Ok, lets just say I use over 1000 and then average the two rates over that. That comes to $0.07 per kWh. 7 cents per.

My computers (rack mount ones) all have 300 watt power supplies and run 24x7 with no power saving (and no monitors or other periphs).

Now I think using 300 I come up with it taking 3.33 hours for my computers to burn 1kWh (1000/300), and thats 7 cents worth?

So 7 cents every 3.33 hours, not sure about this but thats what my primitive "figurin" comes to.

24 / 3.33 = 7.207
7.207 * .07 = .50449 (50 cents a day)
365 * .50449 = 184.13855

$184 bucks a year if I am doing this correctly.

Thats more than I would have guessed. I would run it just from one machine even if it werent a measurable dollar amount (and I didnt know even what the amount was before this post ;)).

To me its actually more important that the electricity is plain ole not getting used and things are more efficient than the money savings (less use of coal).

Again I admit the tree hugger crap and proclaim there is nothing wrong with it, quite the contrary its responsible and long term thinking oriented and to NOT do it, even when cost isnt a major factor, is irresponsible and short sighted.

RE: Fedora Core 3 Review

Wait.... you have machines in a rack mount that are not even turned on!!! How does that work? I thought the whole point of putting computers in a rack was so that you could turn off the lights and stare at all the little green, red, orange lights. That and be able to sleep to the pleasant white noise humming. Plus you did not calculate how much you are saving by not having to use your heater as much in that room.

RE: Fedora Core 3 Review

lol.

Its in the basement, tucked away in its own little corner of the unfinished storage/gym room (with free weights an elleptical and a stationary bike collecting dust in another corner ;)). Its actually a sweet setup.

Its an old cab from my IBM days (well half cab, standalone half on wheels) and it has a glass front and door and all that. Nice rack mount switch, 4 4U machines with sleek black cases (I originally built them out for separate firewall, file server, web/app server and dev/play machine, and back in the day I built them 4U was some cool homegrown stuff), and yes little green, red and orange lights. For now though I live with just lights on the switch and one machine.

But you are right about the heating costs! In winter its nice in there, in summer though its the opposite issue, I open the case glass front and deal with more noise (not much but eh its some) just to keep more air flow, it gets hot .

RE: Fedora Core 3 Review

Man that reminds me of Cooper's place when he was next to the park. They had one room full of Glass Front racks and shit. I was drooling to whole time I was there - luckily no one noticed my envy cuz they were all plugged into EverCrack at the time.
