Cyberweek Activities

This being Cyberweek...I tried to cram some stuff in other than just recovery from Chicago Tardis into this week.

Though I haven't actually gotten to all the things yet...I felt that I should start this post before I forget all the things I wanted to cover. Too late :no:

Anyways...one of the important items was new CO detector. I used to have a First Alert CO400?, battery operated CO detector that took a couple AA batteries and didn't do much else. I was looking to buy something like it again, except reading the negative reviews on amazon.com... a number of other people were complaining that unit disintegrates when you try to change the batteries. Which is why I was needing to replace my old one. So, I decided that maybe I would look at a different brand this time around.

Also noted that these things have like a 5 year life expectancy...though my First Alert CO detector was only a year old. I noticed that Kidde CO detectors claim a 7 year life span (though only a 5 year warranty). Though (in part due to Amazon 'recommendations') I got the Kidde KN-COPP-B-LPM, which has a digital display....showing current CO levels and historical levels, etc. Which I debated on whether I would want to know if there was a CO level, that wasn't alarming.

Don't know if I paid attention to the fact that it uses 3 AA batteries....one odd thing I've noticed, is that it doesn't say if I should replace batteries regularly....but I suspect it'll be part of the same routine with replacing smoke detector batteries.

Though I don't think I'll replace the CO batteries along with the smoke detector ones on December 25th (because of long DST, I had changed my bi-annual to be on or around June 25th and December 25th.) Though, I've already replaced the battery early in one of the smoke detectors. Odd, because there hadn't been any nuisance trips in some time...and it isn't one that is typically set off by these situations. (usually ones that nuisance trip is the detector in the living room [near the kitchen or the first bedroom from the kitchen. Yeah...something I'm burning on the stove or in the microwave is usually the cause.)

But, getting a new set of 4 9V batteries was something I got in my recent cyberweek purchasing...

Freeradius & DHCP Failover

Link: http://deployingradius.com/

So, ever since I looked at adding Mac Address Access Controls to my Airport Extreme...on top of WPA2 Personal, and the fact that my DHCP server only does reserved IPs, security. I used to do Mac Address Access Controls on my previous routers, but it was an easier interface to work with on those. And, I didn't realize how the Time Access worked on the Airport Extreme, the default allow all the time rule at the top tripped me up. So, I thought if I wanted it, I would need a RADIUS server...and I didn't know if I wanted to do that....yet.

But, after I woke one morning and couldn't seem to account for why there seemed to be so much data streaming through my Cox connection...there had been strange spikes in the past, but always figured it was something updating itself while I wasn't home (like iTunes and my podcast subscriptions). But, this one morning...there was no corresponding activity from any of my computers, and I didn't see anything obvious with my TiVos/ReplayTVs. Though I could've just missed it.

So, I fixed the Timed Access control and put my current devices in. With a note that I should really look into installing RADIUS somewhere, so that it would be easier to maintain the list than the airport utility. I would lose being able to find the MAC address of some new wireless device that doesn't have the MAC address stamped on it....for addition to my DHCP server.

Later during the setup in: Another Airport comes to Lunatic Haven I had wiped out the settings....and didn't feel like putting it back in again. Which made it more urgent (in my mind) to get RADIUS working.

So, I went online and searched and searched and searched...on how to do this. I had looked before, and wasn't all that successful. There's no simple how-to apparently. But, I found bits and pieces around, and decided to just go for it.

First, I installed freeradius on my Ubuntu server 'box'.

sudo apt-get install freeradius

It starts right away, now to make it work. And, debug it. Well, most of the examples were for older freeRADIUS versions, so things weren't where it said, or command line switches were different, or it didn't work. I did find some examples of MAC address authorization, but they involved 'Auth-Type := Local' in the /etc/freeradius/users file. But, the clients.conf part seemed right. I strongly considered just doing 'Auth-Type := Accept'...but I wanted to figure this mess out.

client 192.168.1.1 {
        secret = testing123
        shortname = airport
        nastype = other
}

So kept searching and searching....eventually, I found fragments on site called "Deploying RADIUS: Practices and Principles". It confirmed that I was basically on the right track, I just needed to figure out what to put in the users file to make it go from Auth-Reject to Auth-Accept.

Well, the example for MAC Address entry for users I had found was:

001122-334455  Auth-Type := Local,  User-Password == "testing123"

At first I was pointing my Airport Extreme at it and watching the debug output, and watching everything stop working now and then. But, eventually I used 'radtest' to test my freeRADIUS configuration. And, eventually, I found that what I needed was:

001122-334455  Cleartext-Password := "testing123"

And, all was good. I pointed my main Airport Extreme to it, and it everything adjusted and worked. I then pointed the new Airport Extreme at it and things continued to work.

Yay! :cool:

Another Airport comes to Lunatic Haven

That's another Airport Extreme....

The corner where I put TARDIS and my HP Photosmart 8450xi printer have been having switch problems, or at least I that's what I thought. But, I have replaced the only cable to replace, and both switches. But, still the link will drop out of gigabit after a while. And, then it wouldn't go into gigabit at all anymore.

And, then PRTG reports that things over there disappear every night. What's strange is that its always around the same time.

I thought about buying some network testing equipment, and figuring out what it would take to run a new line in place of the existing one (should be easier than what it would take to run one to a new location). Or doing the ugly and stringing wire along the ceiling....

But, things started adding up....and I wondered just how much I needed the speed. Sure gigabit would help TARDIS backup faster, but that's about all over 100Mbps would get me. The printer is only 100Mbps, so no advantage there. And, likely would be the case for any network printer I were to put there. And, likely not much else is going in the corner any time soon that would need gigabit. So, I wondered about revisiting the WDS option using 802.11n now. I had survived for some time with 802.11g WDS both here and in the past.

Looking at WDS options with my Airport Extreme, it pretty much came down to two options....an Airport Express or an Airport Extreme. Express only has a 10/100BaseT port on it and its a big plug type thing, so if I wanted better than 100Mbps, it would have to be an Airport Extreme. I did look at other routers, but hard to tell if it would work or not, and I'd probably want something using OpenWRT or something and things started getting complicated again.

I do someday think I'll get an Airport Express...though it would require that I have Linux solution to manage it, some way to set it up in a turnkey solution....as a travel router.

But, while I was looking at other WiFi router options...I was looking on eBay, so I wondered about an Airport Extreme that way (instead of using my Educational discount on another).

And, I found some pretty reasonable prices for refurbished units, so I went for one.

I got an Airport Extreme

I had been thinking of getting one of these units for a while, though wondering if I could use just as an AP.

Meanwhile, Cox has been improving its speed...but I wasn't seeing the improvement. Could see the upstream improvement, but not so much with the downstream. Well, its an old WRT54GS v1.1....and I guess I've hit the ceiling on it. Though turning off wondershaper (QoS) made an improvement in speed, though still not the full advertised speed of Cox Preferred. Not sure if that's the local competition or the next ceiling.

So, got to thinking that I needed a new router....after some quick searching around, it seemed too much trouble track down a modifiable router so that I could still have wondershaper... and one that offered improved WiFi (since pretty much can't get them without WiFi). When it occurred to me that maybe I'd just jump and get the Airport Extreme.

Without wondershaper on this gateway, I moved the main upstream hogs to go through the other WRT54GS and Internet connection....the DSL service, where things aren't getting me down....

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.
