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'.

Last hiccup with 'box'

While at work this morning, I tried to ssh into 'box'....mainly to make it see the changed ssh host keys. But, turned out it was a test to see that it was working correctly.

I couldn't get to the second ip on 'box'. All my linux servers have 2 IPs, so from the outside they can be hit by either gateway. Using ip route/ip rule, it makes the packets go back out to the correct default gateway for the IP.

Well, turns out the second IP doesn't show up after a boot. If I do '/etc/init.d/networking restart', it appears. But, reboot...and its gone.

After much fiddling, searching, trial and error....I eventually stumbled on it.

The configs were basically the same as my ubuntu 8.04LTS server. Three 'auto' lines for each of the 'iface's. I had tried combining the eth0 entries to 'auto eth0 eth0:0', but that didn't work.

:idea: On a whim, I finally tried having only a single 'auto' line -- 'auto lo eth0 eth0:0' in /etc/network/interfaces. That finally made it have both eth0 and eht0:0 after a reboot. :?:

Now I can ssh into 'box' via either of my gateways. :cool:

Calling 'box' done for now....

I'm can't think any more....don't know what's missing that I didn't intend to leave off.

Sure there's stuff that I wouldn't mind having back, and stuff that isn't readily available for the distro I'm using...namely no mondorescue for 9.04 yet. I also couldn't get DHCP peering to work, evidently the rule that both servers be the same version is important. They would start up fine, but once they talk to each other....the second is over. Perhaps I'll sync the servers when the next LTS comes out.

But, I did get ddclient moved (or rather I moved my configs to the version with ubuntu)...and I updated the ip configs to be like my other strange linux boxes.

I suppose I'll slowly comb through the old 'box' HD and figure out the various strange and twisted thigns I've been doing on there. Such as discovering the strangeness of how I've been doing my IVS Status updates.

I suppose one last item would be to make sure I can burn cds with the burner I moved over....

'box' is starting to return

I got the new-ish computer out and started looking at what I could change in it....while digging into it, I discovered it has a SATA drive. So, that meant no moving the old 'box' harddrive into the new 'box' hardware. So, that narrowed the return options to one.

I transplanted the CD burner in the old 'box' into the new 'box' and then set out to get ubuntu-9.04-server-i386.iso. First tried downloading via OSL....that was going slowly. Noticed there was a .torrent file available, so I decided to get it that way. That went much faster.

But, then I got distracted...ferret, supper...but eventually got around to burning the image and starting the install process.

After remembering the desired sequence of answers that would result in something that I would like (and having it set itself up with out DHCP)...I had ubuntu server with DNS-server, SSH-server, and Mail-server. I set out to work on being able to access the old drive on the 'box', after some thought, I decided to load on 'ubuntu-desktop' I like have lots of windows, and which a much faster system there's other things I'll probably be doing on here now/in future. 'box' started as a Pentium-75, and is now a Pentium 4 3.2Ghz w/HT. I also discovered that the machine has a GigE NIC (it didn't mention this on the website....)

I let 'ubuntu-desktop' install overnight, and found it didn't work in the morning. Had to introduce another 'sudo apt-get update' to get things along. I threw some other stuff I was starting to find that I wanted/needed like, binutils, ncftp, ntp, boinc... and then bounced the box.

Got a USB adapter for the old drive, but 'box' wouldn't see it automatically. It doesn't seem to load usb stuff on boot, looked around but decided that might be a good thing....for now. Doing 'lsusb' would make the drive appear....

I continued to setup the environment, decided to leave it using bash...even though my other home linux servers use tcsh. I also installed GKrellm and worked on getting postfix to talk to relay through my outbound.mailhop.org account. Found that I had to use smtp_tls_CAfile=/etc/ssl/certs/Equ....pem instead of smtp_tls_CApath=/etc/ssl/certs. And, then I messed up resolv.conf (I had installed and tested vpnc, its not quite working right...but its probably a K-State thing than the client....I knew it was working on my other ubuntu systems and I used the same config file, but didn't check if it still worked on those other systems). Then I discovered that my local DNS was kind of confused. Because 'box' was back on the network, but not configured as the master or knowing of my local domain....it was getting things wrong. Using my dyndns domain name is internal and external probably compounded things.

So, that moved up getting DNS configured. Continuing my environment setup, I remembered that I hadn't updated my border routers for IVS without 'box'.....since 'box' has cron jobs to check that I'm my IVS is working....so I went off and did that...and while I was on the computer that I also do my boinc managing from...I worked on getting BOINC running on 'box'.

I opted to use the apt-get install of it, and let it run a system service (instead of out of my local account and the keep it current to the latest stable version...which is newer than the ubuntu one?) Attached to a bunch of projects, discovered new 'box' is much noisier with its CPU running full tilt all the time....though P4-3.2GHz CPUs run hot...I forget what I had now in 'box'....Cele2.2??? Got all the usual projects attached, except Spinhenge...maybe it won't be bad if its not. Not all boxes run all projects that are available, aside from some projects not support Linux. There are differences based the resources of the minion. New 'box' being faster and doing HT, I have it doing more than what old 'box' did.

Now off to do morning stuff and run some errands before diving back into finishing new 'box'.

I think when I return, I'm going to work on dhcp server peering. So that should I ever lose 'box' again, I won't be with out DHCP.....though 'orac' is not the kind of box I hope to ever have to rebuild (another 'lhaven' :>> )

Guess that answers one question about 'box'.

This morning while I was at home waiting for the building owner to show up to see about some noises inside the wall behind kitchen sink/washer&dryer. UPS showed up with a box from TigerDirect.

That should be the off-lease IBM ThinkCenter S51 that I snapped up thinking I'd rebuild 'box' on a new machine.

The condo's quarterly pest control was going to be at 1:30pm today, so he was thinking of setting off some kind of pest control spray bomb in the utility room...which may or may not reach into the wet wall space of my condo. Or consult with the pest control company on what else to try. Later as I was listening closer to the noise, I wondered if it sounded like a feret...because there's a "Lost Ferret" sign out by the mailboxes. Turns out the "Lost Ferret" is from the unit above me.

I popped in to work for a bit, and then returned around 1:30pm for the pest control visit. I arrived to find that FedEx ground had been by and there was a box sitting by my front door. Meanwhile, the building owner said the neighbor upstairs wanted to take a look and see if he can get the ferret out, otherwise the ferret owner would pay to have an exterminator deal with it. There's no openings in the wall that I knew of, but I let him. Pest control guy later showed up to do some spraying.

Well, the box was the pulled/untested power supply that I had snagged off of ebay. All the power supplies that matched the part number online were of this 'untested/as-is' condition...or more than what I had original paid for the computer (and more than what the off-lease computer I just got). Alas, it didn't make 'box' work again. Either I got another dead power supply or there something else wrong with the system that is making the powersupply not turn on. Not have an ATX P/S tester handy, I can't tell if this is the case or not.

Anyways...that eliminates one option for getting 'box' back online.

I'm pretty much leaning towards installing the latest Ubuntu server....since it looks like the main things I'd require on the system are DNS (master), DHCP (wonder about setting up peering), NTP, ddclient x 2, and email relay to my outbound.mailhop.org account, vpnc. The ivs-status-sniff stuff will just go away. And, I'll gradually remove all evidence of it and simplify the configurations on my border routers (been close to running out of nvram on them).

Hmmm, just realized that I never changed the configs on the routers to account for the lack of the internal router 'box' to reach my ReplayTVs for IVS...not just they were (date) confused because they were doing NTP off of 'box'...and first DNS in the search list was 'box'....

Also not sure vpnc is needed now, since it won't be functioning as an internal router anymore. Someday I'll upgrade to a computer where it'll be safe to install a vpn client again. My windows boxes are both pretty dorked in the network config department. The W2K box is completely dorked...when 'lhaven' died...it became pretty usuable because I couldn't get into the configs to change my DNS server. I haven't found the install disk, so risking a repair install hasn't been an option. The other computer is also somewhat messed up, though not as bad.

Both messed up networking are connected to previous attempts to install VPN software (SecureRemote). It was largely flawed because they didn't support users with their own routers doing NAT. Largely because every IANA non-routeable ranges were being used somewhere within the worldwide network of the company, which was all NAT'd behind a single IP in Canada. Made location based (or restricted) services fun to use from work...because they would mistakenly set Canadian preferences or deny access because only US IPs were allowed.

It was particularly bad with Yahoo..which kept bouncing us over to yahoo.ca and then defaulting to only searching Canadian sites.

Anyways....wonder when I'll get cracking on trying to build the new 'box'. The off lease machine came with a 40G drive, but do I use it...or see if I have any other IDE drives around (probably too late to buy one).

:hmm:

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:

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.
