Finally upgraded my home network.

Many months ago, I was looking at the slow WDS bridge from my main desktop to the rest of the network. The rest of my network which includes both of my Internet gateways, as well as numerous multimedia devices (include my TiVo HD and AppleTV)...so I wanted to speed up the transfer of media to these devices from my main computer.

I then decided that I would do it....I would buy a length of Cat5 and a bunch of command adhesive wireclips and plan a route from one corner of my living room along the wall/ceiling edge to the opposite corner of the living room and then back track behind furniture to where my switch for the main computer was.

At some later point I started putting up the wireclips, but stopped once I reached furniture. I was putting the clips in place by standing close to the wall on my toes...so it was a problem where the furniture was.

I stopped and to put things off to another day....many months passed.

I got an Eye-Fi

It is kind of a chore to take my memory card out, put it into my reader and transfer the images into a folder on my computer....so I decided to take the plunge and get an Eye-Fi (Share).

So far in hind-sight, maybe the Eye-Fi Home would've been sufficient.

After extracting it from its interesting package, I skimmed the quick setup (no Linux, so no Eee PC support...hmmm) I plugged the supplied USB reader into my work MacBookPro. And, went about getting it configured. First thing it wanted to do was upgrade its Firmware.

It saw my home wireless network, and got the key from the MBP...and then went to verify itself on the network. I immediately knew it was going to fail, and started looking at allowing it to work on my network. Wait. What's the MAC address of the Eye-Fi card? :??:

It eventually timed out, and it suggested that I may need to allow its MAC address to connect to my network...and provided it.

So, I added the MAC address to my allow list for my Wireless Network and then told my DHCP server to expect it and give it an IP.

While stuck in the step, it asked if I wanted to upgrade the software. Opt to skip, and continued the initial setup.

It presented the online web albums to store at....I saw Facebook was one of the choices. But, seemed to me that any album on Facebook is basically shared with some or all people. And, I tend to want to tweak (crop, sharpen, adjust contract, brighten, remove red-eye, straighten, etc.) before making the public album. Though Java uploader has never worked for me....

Then it offered a local location to upload to. Except that it only offered locations on my Work MacBookPro. Guess can't (easily) have to going to some other storage repository on my home network (initially, I'd probably want a share from my Linux server, but some day I plan to get a NAS device [or two, or more] on my home network). Some day, I'll expend the effort to create this repository....

I then went and did a test shot. It seemed to just barely get the shot transferred when the 1min auto shut off took place. Its advice is disable auto power off completely. Except that's not an option, and not something I want to disable anyways. Instead, I increased it 2min. Hopefully that'll be enough for the majority of cases, without sacrificing my ability to have usable power in the disposable AA batteries that the camera keeps eating up. :>>

Plus I had thought of increasing the timeout...because it is kind of nuisance how short 1 minute is when you are waiting for that right moment to snap a shot, especially when I had to expend extra effort to get things set up (like get the camera to lock focus in the right vicinity).

I poked around in settings a bit more, and then went to my Windows computer to set up a more permanent local storage location.

I popped the SD card into my attached card reader (instead of the supplied one). Installed the software and set things up....I opted to update the software on here right away. And, then changed the location for local uploads. I also set up the web upload, though I'm not sure what I need that for....since almost never share raw pictures. I just manage using Picasa.... Also looks like no magic hook between Picasa Web and the Windows software. At least not in the Web to desktop direction. :|

But, I couldn't access the wireless profiles on the SD card using this reader. So, I plugged in the supplied one. It wanted to reboot my computer to work...I said later, but then it started working anyways. But, not much to do here. This computer isn't (directly) on wireless...so no profiles to transfer over and no interest in trying to associate the card with other networks it sees.

Fiddled around a bit more, and then went back to the Work MacBookPro to update the software there, and to see if I could add additional network profiles. Namely add my work ones without having to take it into work.

But, it wouldn't see the card my SD card slot (# memory card in 1 ExpressCard34 adapter)....Had to use the supplied USB card reader again. This could prove to be annoying. And, turns out....no preloading of network profiles :no: Guess I will need to take it into work to set it up to work on the wireless network there. Also means that I'll still need my computer, and still need to pop the card out, etc., to get on to other wireless networks. Of course, it says it won't work on networks that use transparent and/or captive proxies. That means the only other network that I might want to add is my parents' network. But, the plan was to leave my work laptop at work, the next time I go on vacation. :**:

Wonder how the local computer uploading works from work and other remote networks. Or what happens when I travel and there are no 'open' networks for it to use. Etc. )-o

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. :wave:

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

Dell netbook coming in August, sans Function Keys

Link: http://www.umpcportal.com/2008/06/dell-netbook-coming-in-august-sans-function-keys/

Dell is pushing too little and too late.

Since seeing the power of the ASUS Eee Pc, I've been thinking of getting such a device. Though I wasn't sure if I could handle the sacrifice of hardware to get small, light and low cost. Then others started coming into the scene....such as the HP Mini Note. And, things started looking up that something suitable would be offered.

I then heard rumors of Dell coming out with something in June. And, since there are Dell's that can be had with Ubuntu...this seemed like it might be a good thing to wait for.

But, now they are saying August....I don't think I can wait that long. (too late). And, its not going to have function keys. Well, that's a sacrifice in hardware that I don't see myself accepting. (too little).

Guess I'll take a look over what is available now and pick the one that I'll have live with for the next 5-6 years (that's how old my previous laptop is).

Woohoo. I have faster DSL service now

This morning I woke to find my DSL modem reporting a speed of 1984/512. Reran the spectrum analysis tool at DSLreports. I shows a theoretical 35xx/818....wonder if I could've really gotten the 6.0/768 tier to at least get the much higher upsteam speed. It would've only been $5 more per month. (The tiers were 1.5/384, 3.0/512, 6.0/768 and the prices were $25/$30/$35).

I graph the SN margin/Line Attenuation along with up/down speed from the modem in cacti....so I see that my SN margin has dropped quite a bit, and Line Attenuation has gone up a little. So I see it started shifting gears around 5:20am.

Using the speed tool, I still can't get the reported speed. But, there is a proportional improvement. But, latency has dropped quite significantly. Better than cable now. Well under 100ms.

Don't know when the current DHCP leases expire, but I reconfigured DHCP to tell my Broadvoice VoIP service to use DSL as its gateway now. Wonder if there's anything else I want shift around....

:wave:

URC-6131N

I mentioned that my URC-6131 was failing...the main annoyance was the PVR Menu button. It was getting harder and harder to get into the Replay Menu on my ReplayTVs.

I searched around online to try to find a new URC-6131 (forgetting at first that it needs to be modded to do JP1 reprogramming). But, no luck. I decided I would take a chance try the 6131n. Found it in numerous places.

But, as I was looking at whether to buy or bid....I saw an auction listing that mentioned that the 6131n for sale had been modded for JP1 programming. Oh ya....the 6131 that I had was modded for JP1...that means I should be bidding on this one.

I marked it for future bid....

Another try of the HD-PLC

I fiddled with it a bit more...even with both the master and terminal in the livingroom....I couldn't get the terminal to work from either of the jacks by the computer....and further away...the speed test was poor.

Come to think of it, I use powerline speakers for my rear surrounds...at least they work...though that might be why I can't get powerline networking to function. There might be other powerline network technologies that will co-exist, but the speakers are more important and wireless is acceptable.

Plus I already see myself getting better units down the road. Wonder where I would put them, and if it would be 'bad' if I had DROBO's on both....other than a serious lack of cash for all the tech stuff I want to get this year.

HD-PLC Fail

:..(

Guess I'll have look at some other solution for home network.....perhaps I'll buy WireTracks for the living room....

Anyways...I when I first tried to set it up...I couldn't get link in the storage room. Turns out the plug tab is broken for that cable in the network closet, so it wasn't in all the way. Next I got things set up...and when I put the terminal by the living room computer....I couldn't get it to work there.

Seems there's too much interference in the living room for it to cope with. While going around trying plugs, I unplugged some stuff...which seemed to help a little bit, but not enough. And, I couldn't go without what I had unplugged.

So, for the time being, I'm staying with the current WDS bridging. Wonder if I got a pair of Airport Extreme's...if they would do bridging? :??:

Updated my ugly NetMap

Link: http://www.lhaven.net/netmap.html

Wait...it isn't April 2008 yet.

Well, there's one item on the map, that I haven't purchased yet. But, I intend to order it tomorrow...and I do hope it arrives before the end of the month....but decided the put a future date to indicate that it contains future stuff. &#59;D

It also contains that I'm dropping the WDS bridge for Powerline networking (HD-PLC), that has been ordered...it just hasn't arrived yet. Originally, there was some question of finding an open outlet behind my home theater setup to plug it in. But, then it occurred to me that the adapter could go anywhere on my wired network...since I had made that upgrade....and there's the jack in the storage room that I haven't acquired stuff to put around yet.

There's a plan to do so, but I need to go through the stuff in there to figure out what to get rid of to make space for using it for more than storage. One is to acquire a network laser printer (ideally with color and duplex capabilities, maybe copier)....and locate it here where (rather than next to one of my computers, due to concern on whether I have enough power at those locations U-( ) I'm also wondering if I really need all the features, to maximize the number of other gadgets I also want to acquire....

Meanwhile, I'm already plotting my next addition....Been thinking of getting a TimeCapsule, but now Apple has released the patch to allow Time Machine to storage attached to an Airport Extreme....so I'm thinking that I'll do this, and get a Drobo to attach to it (assuming the pairing will work). Of course, it could be a while before I get around to having all the pieces.

Possibly like the 500GB SATA drive I purchased a while year before I found something to stick it in to.... :crazy: Sadly that was the mirror drive in my Linux server (Orac) that failed recently. I should maybe see about getting Seagate to replace it.... Even though I don't need it for the Linux server now (though I am considering buying an enclosure for it...to mount 4 more drives outside of it....possibly more, since there's 4 regular eSATA ports and 2 PM-capable eSATA ports on the back. Though waiting for a version of Linux that'll hopefully support PM.)

Also looking at USB over ethernet, since I'm running out of space for USB peripherals at my main desk.... This this spot also cries out for the acquisition of a Drobo....since I pretty much to disk-to-disk backup now (since I had long ago past the point of reasonable tape backup [to DLT7000's] of my system, and it seems less and less likely that I'll be buying a new tape drive [LTO1] now). I'm sure if I think some more (oops I did), I can think of other places around here that cry out for additional Drobo's. Wonder if there's a limit to using the GeekBrief.TV discount code.... Though Drobo isn't the only think on the market that might solve my needs, but it is one of the cool looking things. Though it is only a USB storage device....there's an ethernet option for it, but it isn't a native ethernet option...so that sounds like it would be slower than some other sort of NAS product.

Hmmm.....so many gadgets....so little time, money, space, power, etc... :lalala:
