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....

Lenovo 3000 V200 0764-2XU Laptop Computer - Intel Core 2 Duo T5550 1.83GHz, 2GB DDR2, 160GB HDD, DVDRW, 12.1" WXGA, Vista Business

Link: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4538464&CatId=2289

While I was at Penguicon 7.0, I only took my Netbook. (as I had done on a couple other previous trips) Which was adequate for simple things, but I found it hard to use for doing heavy work stuff or blogging. Largely due to the small keyboard and my big fingers.

So, I decided that I should look at getting a cheap 12" notebook. While I was surfing at Penguicon, I came across the above notebook at TigerDirect.

I pulled the trigger and ordered it. It arrived today.

The plan is to immediately blow away the OS and install Ubuntu, not even bother with booting to see what Vista Business is like. I did a quick poking around in the BIOS and plugged it into to charge before leaving for work.

I noticed that it reported the CPU as a Core 2 Duo 2.0 GHz....instead of the advertised 1.83GHz. No complaint there. Though it is listed as a new laptop on the TigerDirect site, and there seems to be finger smudges on the lid under the plastic protection sheet. Makes me wonder.

Anyways...staying with the plan to install ubuntu...and then use VirtualBox to run XP. Since there are some things that I do need windows for occasionally...which was one thing I was missing in not having a Windows laptop. Hopefully all the things, including the necessary hardware support will work that way. Don't really want to do dual booting.

Hmmm.....

UPS Oversight

On Monday there was a brief power outage....I didn't notice from work at first, because the UPS there were no issues affecting the computers at home that I accessed from work. Two didn't go down at all, and one rebooted by itself.

The Windows 2000 had started booting up, but since it mounts shares samba shares from the other box that didn't come up nicely...it was stuck until I told it to ignore trying to remount the share and continue. &#58;&#45;&#40;

The other box is the ubuntu server where the missing samba share originates from. I had set this system up as RAID1, and one of the drives stopped working after the outage. But, ubuntu wouldn't boot without both drives. &#58;&#63;&#63;&#58; Found I had to add 'bootdegraded=true' to the kernel line in grub.

Later the old APC Back-UPS Office 500 started making lots of noise. Time to replace its battery. Or perhaps time to retire it from service. I moved the loads to one of the remaining UPSs, and pulled the UPS while I investigated trade-in or replacement options.

Then this morning, I heard a strange continuous beep.....while trying to figure out where it was coming from....everything went dark. Or rather I saw my ubuntu server go down, and later on the KVM switch I saw that two other computers were booting up. Evidently, the remaining UPS was already handling too much...and its only a 700VA UPS.

I had forgotten that I had a plan to add a (Smart)UPS to the living room and move the Geeksquad 1285VA UPS eventually to run the ubuntu server (since that was the most recent addition, and it didn't have a UPS for it)....so it had been parked on the UPS that runs 'box'. Well, moving 'gumby' definitely put it over the top....probably especially with its 3 external drives. (used to be 4, but one died).

I guess it is not only time to rush on acquiring a UPS to replace the APC one that I retired, but also acquire a UPS to put the Linux servers 'box' and 'orac' onto separate UPSs.

I think I was eyeballing a CyberPower 1000VA UPS yesterday....the question is will it still go in the same place I was looking. Maybe I don't care that much about 'gumby'....though newer UPSs have lots of protected outlets, so I thought it might park nicely next to it and reduce the confusion of the which of the many powerstrips are plugged into which UPS, etc.

Am I at the point yet where a Smart-UPS can materialize, or maybe I'm looking at an additional CyberPower 1000VA (or perhaps something bigger, but still cheap)....

Hmmmm.... &#58;&#104;&#109;&#109;&#58;

Drive Backup Failure

I'm about to take the plunge on buying an external 1TB drive....I had been eyeballing one on and off for some time.

I currently use a pair of 300GB drives (Maxtor OneTouch II's) to do backups of my main (XP) PC. And, I have one that does backups of my other Windows (2000) PC.

But, recently I ran out of space during a backup....which shouldn't be that surprising, since I had recently upgraded the primary drive from 120GB to 400GB. Total raw capacity 650GB. Initially, the plan was the 1TB drive would supplement my backup capacity. Especially since I plan to upgrade the other drive at some point (250GB to 500GB).

Though the backup was running slower than usual, apparently the drive came up in legacy USB mode after the last power outage....so the backup was estimated to take a week or so, instead of the over 8 hours that it had grown to (normally the full runs once every 6 weeks, on Tuesdays while I'm at work....but often it continues to run well into the evening when I get home now)...the incrementals run around 2am and haven't gotten in my way. Though they also only run on weekdays, since they would conflict with tape backups, though I haven't run one in a long time....haven't taken the plunge on getting another pulled drive off of eBay.... Don't know when or if I'll revisit this.

Anyways...I reset the drives (unplugged/replugged) and then they started flying along again....I did notice that one of the drives seemed noisier than the other....and then during the backup, it made some really horrible sounds. So, I guess that drive is failing. Kind of unexpected.

I'm planning that the 1TB drive will support Firewire (the OneTouch II's used to, but I had to change their enclosures....and got USB only ones), hopefully it'll be more reliable. I suspect the USB issue is because not everything I have connected by USB draws power from USB...and some aren't on UPS. ... So switching back to Firewire will hopefully keep things running fast by separating things, if for no other reason....

I had been planning to get a DROBO at some point to be the backup...though it is hard to justify the cost of getting a DROBO just for this type of storage, when I also have a crunch to add storage of other sorts. And, I also have plans to play around with other ways of adding storage....

Meanwhile, I discovered that backups had stopped working some time ago on my other Windows (2000) PC. It spat a disk error when I tried to run one by hand. I tried reformatting the OneTouch II drive, but the format failed. So, I guess that drive is toast. And, I'll be in the market to buy another drive for it.....since that old box only does Firewire. It did have USB (1.1) ports...but some time ago, the port seem to have gotten zapped....because they don't work anymore. The machine has 3 other 300GB drives connected to it for storage. But the OneTouch only backs up system files. The rest is primarily DVArchive storage. And, I'll probably never get around to watching those shows....

The other important archived files are also stored on my (Ubuntu 8.04LTS Server) Linux box (which is doing RAID1. I plan to hang more SATA drives off of it, and see what RAID 5 is like....someday. Would also like to try Port-Multiplying).

So, I guess I'm in the market for 2 Firewire drives.....though the OneTouch II 300GB that was on here was overkill already....so don't know what I'm going to do. This may involve some thought and some juggling..... &#58;&#63;&#63;&#58;

Upgrading the primary drive in TARDIS

Once again, after some thought yesterday, I decided that I'm going to pass on getting a new Windows XP computer. Even though I was eyeballing something based around a Phenom X4 based system. And, my old XP machine is almost 5 years old....and new systems are getting scarce.

What I'm now thinking about is getting both a Mac Mini (for my Home Theater, though this may change or get dropped...depending on my mood, etc.) and an iMac (for the bedroom). What I'll then do is get VMWare Fusion for the iMac, should the need for a newer Windows environment arise. The only question is the timing of the iMac, and the thought of getting an iPod touch. (which cuts into my plan to get a VX8R?)

Anyways...I decided that if I'm going to keep the old XP machine, I should stop procrastinating on upgrading the drives in it. I had seen warnings that the primary drive was going to fail, and had purchased Acronis Easy Migrate a while back with the plan of upgrading this drive. It is only a 120GB drive. I could of gotten larger, but I didn't think I would need all that space at the time. Though I had since added a secondary drive of 250GB, and even that one is getting kind of full.

So, I was about to make a note to myself to buy a 500GB drive, when it occured to me that I had pulled a 400GB drive from the post-icepocalypse Gateway (Core 2 Quad) machine I had gotten. It came with Vista, but I had no interest in running Vista. It was purchased to replace my Linux server, though I resurrected that server....so its just an Ubuntu play box. Though I was hoping for PM support to do raid on it. But, I haven't taken the plunge to see if it'll work for that....so its just a fast BOINC engine at the moment....and some file storage.

Anyways, I decided to upgrade the primary drive in TARDIS using the 400GB drive. I went and got the USB/Firewire/eSATA to SATA/IDE enclosure that I had purchased and set aside for this purpose and set out to try running Acronis Migrate Easy.

Hooked it up using Firewire first....strange, my computer seems to have gotten too quiet. Seems the firewire interface is disabling my sound. But, when I went to 'migrate'...it wouldn't. It failed quickly on the reboot, and various other forms of failure. I figured maybe there was a problem with it being on Firewire. So, I switched to USB.

That didn't help. It was reboot and then fail, and then reboot back to before. I slipped other activities in during the process, and eventually it was late...so I called it a night.

Should've held out for the ASUS Eee PC 1000

I'm starting to think now that I should've held out for the ASUS Eee PC 1000. I'm finding the 901 a bit too cramped in physical size and storage.

I had thought of blowing off the Xandros and doing Ubuntu, which would probably help with space by not having all the stuff that is bundled. But, I opted to stay with the Easy Mode/Xandros. Largely because I'm looking for the device to just work.

I did restore it a couple of times to factory settings, because I took a blind turn playing around with apt-get and ended filling up the root drive and making a general mess of things.

Though I do have an issue with its wireless....it seems to take forever to reconnect to wireless after coming out of standby, and, then more often than not, it then can't connect anywhere. Even though all the settings are right. Have to stop and restart the wireless to make it go.

It'll be a few days...maybe a couple of weeks before I get it all customized to fit the way I want to use it. Partly because I know what I want to use it for, I just don't know completely how to get there.

Compounded by the fact that it is replacing my previous laptop which is dead, and I left my work laptop at work this weekend (and I don't know what next weekend holds). But, I'm not desperate enough to keep moving forward on getting the Eee PC customized to go into work to fetch my work laptop.

But, I have did already crack open the unit. I upgraded its memory to 2GB. Only hitch was getting the new DIMM to fully seat. I have a slot loading USB External DVD burner on order for it...could be a while, its coming from a Hong Kong based eBay seller. That reminds me...I have something else coming from Hong Kong that I'm waiting for.

I'll probably even be on to my other gadget projects before I come back to fiddling with the Eee PC some more. Basically, I had wanted it before classes started, but now that classes have...it may be a while before I can get to it. And, I'm sure by then...the 1000 would've been attainable. The extra 4GB (to 8GB) of the primary drive would've surely made a huge difference on how customized I could go with my stuff. And, I'm sure the extra space of the secondary drive (16GB to 32GB) would've gotten used for something.

Even though the plan is to avoid storing anything long term on the device. Though I'll probably still want some kind of backup plan for it...because it'll be a pain to lose things once its customized.

US-CERT: Multiple DNS implementations vulnerable to cache poisoning

Link: http://www.kb.cert.org/vuls/id/800113

This has been a hot topic lately....which I first became aware of when an urgent ticket was assigned to me on Tuesday to upgrade all the campus DNS servers to a 'safe' version of bind.

During the winter break I had updated the campus caching DNS servers to 9.4.2, but the primary/secondary DNS servers were left running 9.3.4.

The 'safe' versions were 9.3.5-P1, 9.4.2-P1 or 9.5.0-P1.

The main campus caching servers had been running 9.2.3...so they were more pressing to upgrade to 9.4.2. During the break, the data center caching DNS server died...which created a good time to build the latest 9.4.2 version and later I upgraded (and make consistent) all the caching servers to this version.

In response to the urgent ticket, I got all the caching servers to 9.4.2-P1. And, this afternoon I got the primary and secondary DNS servers upgraded to match. I also discovered that the secondary DNS server had inadvertently been acting as a caching server to the whole world. After I turned it off, there were lots of log messages of comcast addresses being denied cache queries....and it was for a variety of well known sites, including youtube, paypal, google. At first it was Michigan comcast, but later I saw numerous other states, such as FL, GA, CO....

Meanwhile...I had started looking at getting the new bind package onto my Linux servers. These servers are well past EOL. So, I knew I was on my own to get things work.

Anyways....I was able to get bind-9.4.2-P1 to build and eventually run on both my RedHat 7.3 server and my SuSE 9.3 server. &#58;&#119;&#97;&#118;&#101;&#58;

Guess I need to update my ubuntu (8.04 server) from its desktop....

Upgraded to Hardy Heron

Of course, I'm talking about my Ubuntu server (well, maybe not obvious....except that I'm not known for doing upgrades).

I had debated waiting for Hardy Heron's release before building this Linux server. Except that I had bought the box back in December, and delaying was preventing was delaying all that BOINC work that I've been doing.

There's other stuff I want to or have thought of doing with this server, but don't know where I actually stand on doing those sorts of things. If I had it to do over again, I don't think I would've gotten this box (it was knee-jerk response to replacing a dead server, which I was later able to resurrect...negating the ordeal of recreating things). OTOH, I probably would've continued on with buying something else....and I'm not sure if I would've been that happy with that purchase. Of course, it has delayed that purchase....and it may become too late to get it. Though perhaps Windows XP will continue to still be available after June 30th, and I'll make that one last upgrade in that department.

Anyways...other than taking much longer than expected to upgrade....either the upgrade servers are still badly hammered, or Cox is throttling me. Cox seems to be sluggish in general today. The download speed was dismal. And, then hidden in the terminal you don't see my default, it was asking if I wanted to proceed with the upgrade after everything had been downloaded.

Annoying enough when doing 'sudo apt-get upgrade', even more so here....because I wasn't expecting that I had to wait and interact (with a hidden screen) in the upgrade. Later there were dialogs that popped up on stuff that wanted input, mainly to decide if stuff I had configured in Gutsy could be unconfigured in the resulting upgrade to Hardy. Umm, I configured those services so that I could use them....

Finally it was done....it took forever to boot while it did fs checks on /home and /MMCVideo, but then everything looked fine.

Well, not totally. lm-sensors was changed, so I had to reconfigure that, and I'm not sure but the core temperatures seem to be higher now. The default is FireFox 3.0 beta....and all my extensions and themes got disabled. I've been avoiding upgrading to FireFox 3.0 on my other machines for this reason. Though people say that the new version is faster, and the memory leak is fixed, and some of the hanging/crashing problems on Mac OS X seem to be gone. But, I want it to work the way I've customized it....

So, I changed my shortcut to launch firefox-2 instead and reverted things.

Now other than network lag, which I hope will clear up on its own....the only main thing that doesn't seem to work in the update is vmware. Which probably just means I need to rebuild the kernel stuff again (or see if there's some hardy specific details to making that work). Not really a big deal though, since I never got around to running anything in vmware. It was on my list of things to try, but now I need more disk on this box.

I heard 8.04 was going to have support for PM SATA, wonder if that's true and if the PCIe PM SATA card that is in the box will now work, etc.

Gateway GT5636E Progress

As I may have mentioned, I finally turned on this computer on Saturday.

I had first tried installed OpenSolaris, but it choked on the motherboard's SATA controller. Though maybe I gave up too soon, but I had pretty decided a couple weeks ago that I would ultimately be running some Linux distro....largely for its better support for BOINC and feeling that I would go with running VMware, rather than see what the state of Xen for Open Solaris is. Plus there other software considerations.

I had settled on first trying Ubuntu 7.10 Server 64-bit....it didn't go well. Since I had gone to the trouble of getting a pair of drives for RAID 1, I wanted to do this. Though I was ready to try Storage Foundation with the OpenSolaris attempt. I opted not go this route for Ubuntu.

After numerous installs and going by various community docs...I was about to give up and seek out some other distro of Linux. Until I went back and checked my notes on how I had gotten RAID to work on a Linux box at work. Following that, I was able to get it to work.

Once done, I added ubuntu-desktop so that I could do more than just the mail(satellite)/samba/ssh services that I installed. I had previously installed other services, but decided that wasn't what I was going to be using this box for.

Final step on Sunday was to install BOINC and attach to all the projects I participate in. And, let it loose.
