lhaven upgraded

AKA the end of RedHat 7.3.

For sometime, I have thought that it was time to upgrade 'lhaven' to a more modern release of Linux.

For the longest time, 'lhaven' has been running RedHat 7.3 (it was 7.2, but then I discovered Fedora Legacy...and they were providing patches for RedHat 7.3) And, there are still some production servers running this release, but I no longer have to support them...as I no longer work there.

The problem was that I had compiled a lot of custom apps over the years, that would be difficult to upgrade to newer distro/release of Linux. Since they were done without though to going to a different distro. 'lhaven' did used to run older versions of RedHat, and had been upgraded to where it stopped. But, to go to another distro would require a major effort. And, some of the apps were hard enough to get working to begin with. And, were some what fragile.

'lhaven' has also gone through some hardware iterations. The first major was when the Cyrix 233 that it was one burned up (a transformer had blown a phase, causing really low voltage before it went out....) though more likely it was its return after the outage with none of its fan able to spin. It was working for a while...but then there was smoke, and it all ended.

Got a Duron 800Mhz machine, which grew to an Athlon 2000....and had its motherboard replaced after the icepocalypse. The icepocalpyse was the first time I had to seriously look at upgrading from the old RedHat 7.3....but later I found a compatible motherboard and got the system to boot. The machine I bought at that time became 'orac'.

Later my use of ReplayTVs dropped off, and the one of the main apps that used datadirect for guide data was never successfully updated to support the newer schedules direct service. And, that was one of the things I didn't want to touch. But, now it is gone.

More recently, I started moving some of the other things that ran on 'lhaven' to 'box'. Namely, MRTG and cacti. I also updated all my linux servers to be able to handle mail for my home network, with the local mailboxes on 'box'. Also moved secondary DNS to 'orac' (someday I plan to get fallback DHCP on 'orac', but that'll probably come later.....) During the icepocalypse I had moved DHCP and primary NTP and DNS to 'box'....'lhaven' came back as secondary, because the old 'gumby' was sufficiently broken that I couldn't get it to not require 'lhaven' to function.

So, what I did was install ubuntu-10.04-alternate-i386 to become the new 'lhaven'. Which was the suggested to do RAID at the start, it had been a long time since I had done it, but the last time I had...it was a server install. But ubuntu no longer supports 32-bit hardware as servers, but both 'lhaven' and 'box' are 32-bit machines.

Took some figuring out, but its all done now. Yes, there's a desktop on all my Linux boxes, though 'lhaven' doesn't seem to be really up to the task. The video seems pretty poor and fuzzy compared to the other Linux servers. Perhaps I'll see about replacing its integrated video with an NVidia card of some sort...what that does CUDA, though it'll have to be a PCI card.

Anyways....after the install was done, I installed a few basics...like boinc and called it a night.

Yet another PowerSource 400

Wonder if the people at Xantrex or Amazon.com are wondering what's with all the PowerSource 400s I've been buying?

The latest acquisition brings the total to 5. With the latest being the 3rd unit in one room.

Somewhere in a past shuffle/outage...I had lost a UPS (CPS700AVR), and lost a computer (box). I had rebuilt box, and as interim....put it on the PowerSource 400 that was backing up 'lhaven'. I also put the 8-port [end] switch and my wireless access point onto this PowerSource 400.

This cuts into the available runtime, and its important to me that 'lhaven' never go down. Though its also important from the operation of my home network that 'box' never goes down. And, of course, the switch...and maybe the wireless access point. Though other parts of my home network are on different PowerSource 400's. The stack of equipment at the DSL point is on one, and the stack of equipment at the Cablemodem point on another (though it also includes extra things like 2 TiVo HD's and Expanders and other HT equipment)

So, I have moved 'box' and the network equipment here to the new PowerSource 400....leaving 'lhaven' on its own.

Now the question is whether or not there'll be another 1 in the future....for 'orac'.

What about box?

The linux server known as 'box' died from the rain storm on Monday....well, the powersupply had been iffy for a while, and guess it toasted when things came back.

Sounds familiar....since its predecessor died in a similar manner....transformer blew....but that was fine, I was protected. And, then its UPS ran down...and all was quiet. It was also like 100 degrees that day....so it was pretty miserable. But, when power came back...it resumed like a good server, but the fans in it didn't. So it burned up.

Something like that probably happened to 'box'. Actually the predecessor was before 'lhaven'. The problem was I later learned that the replacement's BIOS had no disposition on what to do when power is cycled (no stay off, turn on or last state option). It always stayed off. The old 'lhaven' was a PC-AT system, while the new 'lhaven' is ATX. (post icepocalyse this problem was fixed).

So, after losing core services due to a power outage leaving 'lhaven' off....I decided I needed a new server to run these services on (DNS, DHCP, NTP). I didn't have to be much, so my then employer was having an auction of old computers....and I picked up a Pentium 75.

Wow, that's slower than the first PC I ever owned (before PC I was a Commodore person). I had acquired it with the plan to run ShareTheNet or some other Linux router thing...this was before Sveasoft and the other options became available for the WRT54GS....which is what I do now.

But, I installed SuSE on this P75 and was in business. Over the years, the hardware has changed. Actually it might have initially been RedHat, I did have a harddrive fail (they were 40G drives from ReplayTV upgrades). But, the current incarnation is SuSE 9.3 based.

Along the way there was a newer off-lease Dell that I acquired from eBay....move drive, let it rediscover hardware and make it go. Then that computer failed. So, I got an off-lease IBM NetVista from TigerDirect. Drive transplant, make it go.

By this time I was getting fancy with the stuff I was doing on it. At first it was be an internal router for my ReplayTVs, so I can sniff the progress of IVS transfers. Later it was run pulsed so that my Sprint 8703e could be bluetooth tethered. (something that I had taken for granted with my T-Mobile 7200....used tethering a lot during the first month I moved to Manhattan, KS...because I was having trouble getting Cox....missing the a few feet of coax between the pole and the box outside).

There are/were other things on here...aside the obvious of BOINC, there was ddclient and it was also the Linux box with a CD burner (for when I don't want to walk to my Windows computer and use the CD or DVD burner in there). 'orac' has a DVD burner, but I haven't used it yet.

Anyways...the question is will I get 'box' working again (either by fixing its hardware, or move the harddisk to a new machine and make it go again)....or make a new 'box' and recreate the core services. I no longer need pulsed (even though I don't have tethering ability with my iPhone, and I don't plan to pay for it....tethering is something I only do in a pinch, so I don't want to pay for something I hope to never need. At least with voice minutes those rollover, even though I hardly use them still.)

There's a certain temptation to load ubuntu and run these services, and then be able to keep the box current (more easily, it was fun building bind a couple of times....) Or hacking the system to support the new Daylight Saving Time.

OTOH, I kind of liked that the machine rather changed for something that was supposed to just be like an appliance.

Hmmm.... There is Ubuntu 8.04LTS, this is what 'orac' is running....ya, that's what I might do. Doesn't matter about the other versions of Ubuntu that I also run here and there. Having them all the same isn't an issue.

I guess it largely depends on whether I go with a different computer or fix the old computer. Both options are on the table now...since I have another IBM off lease computer on order (a ThinkCenter S51, IIRC and a powersupply [pull, untested] from eBay.) I think the 'new' computer will arrive first though. Though it'll probably be sometime before I get a new system up to the same level that 'box' was.

Oh yeah, 'box' was also an SMTP server....had moved that from 'lhaven' during its downtime following the icepocalyse. That reminds me....need to see which mail server 'tardis' and 'lunatic' are pointed at....'orac' was pointed at 'lhaven'....had found this morning that 'gumby' was stuck trying to send mail. (wallwatcher output to DShield)

Hmmm..... :hmm:

Rainapocalyse: The Post

Last night I experienced another Kansas Weather Event. Starting to wonder if I had known about these things, would I have called Manhattan, Kansas home?

Last night it was rain, and lots of it. I may as well have been a solid water coming down everywhere....almost the instant it started....I could hear water pouring into my living room. I had towel handy, and the put empty trash containers along the patio door and that kept most of the water at bay.

Carpet was dry by morning.

But, then the inevitable next happened. The power flickered and then went away. I was watching TV at the time (L&O: Criminal Intent). Guess I'll have to pick up the ending later. Things were humming on the UPS. Though somethings bounced...I turned off the TV and the V880N. Seems my HDVI5 switcher isn't on a UPS. So, there was no using things while the UPSs beeped. I thought I had disabled the beeper in the UPS, but maybe it only disables if it knows there's a computer attached....there isn't so...hmmm.

The UPS handling 'lhaven' died immediately. So, no IRC. So, even though the cable modem was still working and lasted more than half an hour. And, the DSL modem never went down. I was quickly without Internet, as computers ran down. And, my wireless access points are connected to desktop UPSs. I think I should move the access point to the PowerSource 400 that was backing up my phone/VoIP/router/dsl.

I went around shutting down some other computers to help stretch the UPSs....

Seems the Lasko floor fan and the Kenmore Envirosense air purifier didn't like being on the UPS...probably the TRIAC to make low speed fan and the simulated sine wave of the UPS output not getting along. I turned these things off. And, then after pacing around for a while, and checking various light sources. And, finding it getting warm and stuffy indoors. I went out and listened on my HT to the weather spotters, and checked out the area.

Now instead of subjecting some poor random forum to a long rambling thought, I will try to consolidate those things into this blog where they can be more easily ignored profess to be collected thoughts from my mind.
