The UPS and HT shuffle

Even though I was up before noon and could do something dangerous, I got lazy and procrastinated the morning away. Continuing the lack of motivation and go out and do stuff, I jumped into the latest equipment shuffle.

I started by turning off the UPS on the left side of my HT rack and seeing what went off. And, then started removing cables and stuff, making sure I knew things were going as expected. Plus there were other cables to nowhere or longer loops caused by the removal of some ReplayTVs and related components.

Then, I moved my 2 TiVo HDs to occupy the void that was once 4 ReplayTVs (at one time 5, but I had removed the dead one some time ago). And, then I swapped the GeekSquad 1285 UPS for the PowerSource 400.

With things powered up, the guage is reading 120W for load. That's pretty good, guess the numbers I pulled off online were a bit too conservative. Means there'll be ample capacity to add another TiVo HD + expander when that time comes. Though alternatively, there is the new void on the right side caused by the movement of a TiVo HD. And, I'm sure the SmartUPS on the right side can handle having a TiVo on it again.

So, it was time to go put the GeekSquad 1285 back into service.

The first plan was to put 'box' on it. And, maybe the monitor. There's an APC BackUPS 1500VA that is powering 'box' and the monitor along with my Windows stack. So, 'box' and monitor needed to move. Ideally, 'box' would go on a PowerSource 400, but that one hasn't been purchased yet. But, once I traced out the cables and discovered some quirks (by accidentally pulling the plug on 'orac'.) I got 'box' and monitor onto the GeekSquad 1285.

Then I noticed the annoyance. The 'silent' icon was no longer lit. Guess that explains why it was making a racket last power outage. Apparently it needs utility power to remember its settings, seems kind of lame. So I got my laptop and set about to reprogram it.

While I was connected I saw that runtime was shorter than I expected the move would get me. Guess 'box' draws quite a lot of power, and the UPS isn't really up to that kind of task. Even though it would also be bad, I ended up putting 'box' onto the PowerSource 400 that backs up the network switch and 'lhaven'. Guess at a future date, I'll move 'box' and switch to a separate PowerSource 400. That'll be fun.

I put the GeekSquad 1285 to back up 'orac' and monitor instead. Interesting that Gnome Power Manager saw the UPS, and seemed to indicate that it knew what to do now. Guess we'll find out next outage. Not sure if that means I should be looking at a UPS other than another PowerSource 400 to protect 'box'. Its a trade off....I would rather 'box' never go down in an extended outage, though it is also modern enough now that it should detect and handle modern UPSs as well.

I guess we'll see when the next impulse hits.

Of course, there's the question of what to do with the now retired CPS1500AVR-HO and CPS700AVR. :hmm:

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:

Resharing my Internet Connection on my Ubuntu Laptop

Yeah...I've done it.... :cool:

using firestarter and dhcp3-server.

Last trip I went on, I found myself wondering if there was some way to re-share my hotel internet connection to my various devices (namely my Eee PC [w/eeebuntu] and my iPhone 3G). The problem was the hotel Internet was pay $9.99 per 24 hours, and it was per MAC. For that trip, I confined my usage to the EeePC...and used 3G service to satisfy my iPhone needs. Which would probably be fine in most cases....

Though I'm sure someday I'll run into a situation where I'm in a non-3G area and want more speed, or in an area with no service.

I remember hunting around for how to do it then, but eventually forgot about it. But, recently a friend brought the question up, and I got to thinking about the problem again. Since then, I had acquired a 'real' laptop...and had ubuntu 9.04 on it....

So, I started researching for an easy way to accomplish this. After much turmoil and some miserable attempts...I concluded that the WiFi <-> WiFi was definitely a no go. Though it would've been the most desirable.

Leaving my laptop to connect by WiFi...and the resharing on another WiFi to my other personal devices.

Figuring that I might arm myself at some future date with a travel WiFi router to solve the WiFi <-> WiFi scenario...I tried the Wired <-> WiFi situation.

Upgraded Lenovo 3000 v200 to 4GB

Now the reason I was on TigerDirect in the first place. I was ordering upgrade memory to take the Lenovo 3000 v200 that I had gotten from them from its stock 2GB to 4GB (max).

It had said that the 32-bit Vista on the machine wasn't going to see it all, but I blew that away immediately...so I didn't care.

I probably should've shutdown down (turned off) laptop before I swapped the memory...instead of doing it while it was in its suspended state. But, I had a brain fart.

Booting up, I saw that it was 4GB in the BIOS...but then only 3GB in Ubuntu. After a quick search, I found that the desktop kernel is config'd that way. And, the solution was to install the server kernel.

I did that, and now it sees all 4GB. I had gone 32-bit because of certain repos...namely Boxee....didn't support 64-bit.

After booting up, I tested a few key apps to make sure there wasn't any issue in the installing the server kernel. Namely, VirtualBox (booting my XP VM), Boxee (clicked the wrong shortcut), Skype+Webcam (sudo modprobe gspca_m5602 and then starting skype with the v4lcompat1.so PRELOAD). And, then confirm that it'll suspend when I close the lid, and resume when I open it.

Now off to stir up some other trouble....

I recovered from Trend Micro OfficeScan

I was about to activate the Windows XP VM I got running on my new laptop...but something wasn't working right. Apparently K-State screwed up again, and is distributing the Managed OfficeScan client as the Unmanaged one. And, somehow it was interfering with my network connection....but it wouldn't let me unload it temporarily.

I tried removing it, but it also wanted a password... I tried the remove procedure I found on Trend Micro web site, which was to stop services, remove files and remove registry entries by hand. It stopped the AV software, but it made my network problems even worse.

I tried a repair install of Windows XP, but that didn't do anything. So, I reinstalled the alledgedly Unmanaged version again (still Managed &#62;&#58;&#45;&#40; ) And, then ran its uninstaller.... Didn't help. So, I tried going through register some more purging more registry entries. Removed some stuff I shouldn't have....in order to rid of stuff that might be in the way.

Did another repair install of Windows XP...and network came back. I got things recustomized and then I opted to install Free AVG this time around. It did warn that it thought there was another AntiVirus program already installed. But, went ahead. Things seem to work now, and then I went ahead and activated.

Now I can do windows updates.... Not sure what else I actually need to run in the VM...I suppose the next thing I want to do is install Eye-Fi manager. One of the few programs that I missed when traveling with a Linux only laptop.

Couldn't add my parents wireless network to my Eye-Fi card....(there's a linux program that claims to do it, but it only does unsecure or WPA networks...my parents run WEP. Actually, retired the WDS bridge to connect rooms in my condo...I was also running WEP. Couldn't do WDS and WPA...just WDS and WEP.

I survived....and then felt like experimenting

This morning, there was a loud beep along with a variety of other strange sounds that woke me. The power had gone out. I could still breath, so my PowerSource400 was doing its job.

I don't yet have the humidifier plugged into the PowerSource400, but I was only using it in passive mode last night. Though I was told in chat that it'll work on an inverter, so it would work on the PowerSource400. The brochure even touts it as a feature of benefit to truck drivers and campers.... Didn't occur to me to find out. Though biggest problem is forgetting to turn it on at night, and/or turning it off in the morning.

Almost as soon as I was fully aware that the power was out and that I was still getting air....there was another beep, and power was back on. I went back to sleep for a little while longer....

Later I saw the clean air filter light was on the air purifier in the room next to my bedroom, so wondered if the air cell would fit in my ultrasonic cleaner. So, first I cleaned my cushions using it....and then found the air cell was too big. But, also time to replace white filter....or rather swap a white filter in for the grey filter....gonna say it picked up a long more funk because I traveled last weekend....

Also in between cushion cleaning and air purifier cleaning...I decided that it was time to try my hand at modifying my ComfortLite II mask. Guess we'll find out how that works tonight.

Finally, I was looking at my data...and decided I should see if I can get EncoreViewer & USB reader working on my new laptop...where its running Ubuntu...with Windows XP in a VirtualBox VM.

Had lots of fun trying to get USB working, but basically it was combine various information found online on the subject...until I got it to work. There was a bit of VirtualBox/USB and Intrepid. udev file didn't quite match, since there was already a vbox one that did the same thing that it described. Another forum post had a different method, but talked of creating a separate group...make the device nodes in that group...and adding vbox & user to the group....while the 'VirtualBox/USB' method said add user to vboxusers group.

What I went back and did was have it make the /proc/bus/usb device nodes for the vboxusers group...and then finally the devices showed up (after a reboot).

The XP VM detected the USB devices, installed drivers and the light turned green....EncoreViewer started reading the smartcard, but then it failed. I fiddled some more...eventually rebooted the XP VM, it did a bunch of stuff (some 33 updates?)...and trying again, I was able to successfully read the smartcard.

Then it was a matter of copying some files from my desktop to the VM, so I could have the historical data. Laptop way will just be so I know it would work rather than use it regularly....of course, that might change if I make it the bedroom computer after the rearrangement. Though I'm thinking a whole new computer would go there....perhaps one of those ASUS atom based all in ones.

Hmmm....

What kind of trouble can I get myself into next. &#58;&#104;&#109;&#109;&#58;

Penguicon 7.0 & CPAP

I went to another Penguicon, at Penguicon 6 I had earned whuffies which I used to get a shirt for that con and registration to the next one. At Penguicon 7.0, I earned just enough whuffies to get registration to Penguicon 2010 (I had purchased a shirt). At first I hadn't decided if I would go for Penguicon again...but once I started earning whuffies, I needed to find some reason that I was earning them...and eventually settled on getting registration to come again next year.

Anyways....Penguicon 7.0 was also my first trip anywhere since I started CPAP. I survived, in fact I miss it. Since I slept better in the hotel room than I do at home. I always thought I did in previous travels, now even more so with CPAP. I would wake feeling refreshed (and not needing coffee), and I could make it most of the day before getting tired. Now that I'm back...the not totally awake and needing coffee in the morning is back.

I decided to leave the 'do not disturb' sign out all the time, and not have housekeeping poking around. It also took the pressure off in using my hotel room for more than just sleeping at night and during the con. So, no more going out for breakfast and then coming back to use the bathroom, and worrying that housekeeping is going to come barging in or skip me...or be in my room and prevent me from using the bathroom.

I was worried about running out of shampoo, but turned out to have ample for the 4 nights.

For some reason I swear my machine was quieter in the hotel room, perhaps its because the night stand was open in the bottom from just the front, and I put the machine in there. So the machine's noise was shielded much better. The IKEA night stand I have at home is open front and back....and not as low. Don't know if this is something I'll look at addressing should I ever get around to rearranging my bedroom.

There were other improvements....like I didn't fall asleep on the 3+ hour shuttle ride to the airport....though I found it really boring, and I was kind of all annoyed about the fact that I reserved the trip on April 4th...but RoadRunner lost my reservation and then the driver seemed annoyed that I was holding up his departure. But, the shuttle arrived ahead of schedule at the airport.

Then the RoadRunner trip coming home came in slow....because before the scheduled pickup, it dumped a couple quarts of oil and was continuing to leak. Before we left Kansas City it had to stop and have 3 quarts added to it. There was no stop in Lawrence, so then stopped in Topeka at the RoadRunner office there, so that the engine could be shut off some some more poking around under the hood.... Then one of the passengers (a backup driver for RoadRunner), as we were coming up to the Manhattan, KS turn off from I70, had the nerve to suggest that since I was the only passenger going there...that the driver should skip going to Manhattan so that he could make sure that he gets to Junction City.

Things also got really noisy, took on a guy in Topeka who was blasting tunes on his PSP (the passenger/backup driver pretended to poke at the PSP from behind, I just had to put up with it)....and then there were 3 small children in the back, who now awake (having slept through everything else) were adding to the noise level in the shuttle.

Wonder when I'll be able to plan American Eagle flights out of Manhattan?

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.
