SNMP on OSX

ken — Sun, 08 Jan 2012 02:58:09 +0000

NetFunctional is about to release an SNMP based app, so I’ve been testing it against all sorts of various devices. Since OSX is Unix/BSD based, it can be an SNMP agent too, once you configure and enable it. Here’s how:

sudo vi /etc/snmp/snmpd.conf
Find the line
rocommunity public default .1.3.6.1.2.1.1.4
Replace it with (note: you may wish to change ‘public’ to something less default):
rocommunity public default
Save and exit

Then simply enable SNMP to be loaded all the time (this works on Snow Leopard and Lion)

sudo launchctl load -w /System/Library/LaunchDaemons/org.net-snmp.snmpd.plist

Titanium – Vertical CoverFlows

ken — Sat, 29 Jan 2011 00:03:48 +0000

Coverflows are great, but what if you want to do a vertical coverflow? So you can flip up & down between images, or options, etc…

This is insanely easy in Titanium –

// Build your Cover Flow as usual... 

var images = ['option1.png','option2.png','option3.png','option4.png'];

var view = Titanium.UI.createCoverFlowView({
    images:images,
    right:400,
    left:0,
    top:70,
    height:678 // Remember - we're going to rorate 90 degrees, so this is actually width...
});

// Apply the transform.  90 to rotate Clockwise, -90 to rotate counter clockwise.
view.transform = Ti.UI.create2DMatrix().rotate(-90);

// Don't forget to add to the view...
win1.add(view);

And you’re all set.

Upgrading Cisco Phone Firmware without upgrading CME

ken — Tue, 28 Dec 2010 05:23:13 +0000

Needed to reflash a 7961 from SIP Firmware (8.4.2) to SCCP (I snagged 8.5.3. I know 9.x is out, but one thing at a time…).

This took way longer than I thought… I’d forgotten than since I have nicely organized firmware files (eg: flash:/phone/MODEL/) that I needed to alias the tftp-server commands. So we ended up needing:
tftp-server flash:/phone/7941-7961/SCCP41.8-5-4S.loads alias SCCP41.8-5-4S.loads tftp-server flash:/phone/7941-7961/apps41.8-5-4TH1-6.sbn alias apps41.8-5-4TH1-6.sbn tftp-server flash:/phone/7941-7961/cnu41.8-5-4TH1-6.sbn alias cnu41.8-5-4TH1-6.sbn tftp-server flash:/phone/7941-7961/cvm41sccp.8-5-4TH1-6.sbn alias cvm41sccp.8-5-4TH1-6.sbn tftp-server flash:/phone/7941-7961/dsp41.8-5-4TH1-6.sbn alias dsp41.8-5-4TH1-6.sbn tftp-server flash:/phone/7941-7961/jar41sccp.8-5-4TH1-6.sbn alias jar41sccp.8-5-4TH1-6.sbn tftp-server flash:/phone/7941-7961/term41.default.loads alias term41.default.loads tftp-server flash:/phone/7941-7961/term61.default.loads alias term61.default.loads

telephony-server load 7961 SCCP41.8-5-4S create cnf-files exit

And a few reboots later, happy phone on new firmware.

Construction, Part 8

And we’re done. Well, nearly… just have some fine tuning on the Tunnel (see photos) and that’s about it. I reassembled everything tonight, including the newly painted tunnel, and glued down the rest of the track + buildings. My mother bought a few more sets, and once I saw the Airport set I had to add it, so those are now part of the layout. So I’m 17 days early… not bad!

Some photos:

Time to make tracks. Or at least, lay them out!

I did the initial track layout this evening, spending a fair amount of time futzing around trying to get things right. Van’s requirements were that all buildings/activity areas were as close to the edges as possible, and I managed to do that. So after a sign off for approval, it’s time to glue things down. I’ve got about 15% of it glued down – after the 10 pieces, I began thinking this would be faster with my nail gun. Don’t laugh – I saw the Chuggington Train Table @ Mastermind today, and noticed that’s how they seemed to put it together…

But me for me, it’s No More Nails Panel + Trim Adhesive.

Construction, Part 6

After some slow progress, it was time to make mountains. I finished up the mountain casting, and started painting.

Taped up and the initial black foundation coat applied.

I used flat black spray paint to put a quick foundation coat in the areas where I wanted some definition.

Finished painting... time for clear coats!

Next up was a few coats of clear coat to protect the mountain from small children. I expect I’ll be doing repairs within 3 months, but hopefully not sooner. The back of it will be against a wall, which should help keep things together a bit longer.

Quick Update

ken — Sun, 24 Oct 2010 20:46:22 +0000

Progress took a hit while I was effectively out of town for 2 weeks – however I did manage to finish all of the sanding, staining and painting. As well, all the track + buildings have shown up, sans 1 set of 8″ track that won’t slow me down.

I’ve built up the mountain backdrop, and have started the slow process covering it with Claycrete. The stuff takes at least 3 days to dry, and doesn’t cover a whole lot (I initially bought 2 pounds, but picked up 2 more today). Grabbed spray paint so once it’s done I can spray them slate grey and then put on a few coats of clear coat.

Not much has changed, visually, however several coats of Minwax Polyacrylic have gone on the table tops. It’s a slow process, brush on, wait a few hours, lightly sand it, and then repeat. I’m hoping 3 coats will do the trick, but won’t know until tomorrow.

Hit Mastermind again today to get a few Chuggington pieces, as the height of the trains seems to be a bit taller than the Thomas steamers. Need to compare the Over/Under kit i picked up for clearance against the Thomas ramps and make sure everything will fit. Also completed the boys Christmas shopping while I was there

Chapters shipping part of my order… however I now feel I should open a Thomas store. Mastermind started selling the Chuggington Woodend Railway line today (Toys R’ Us has the incompatible Die-cast version), so Van took Preston as promised, and they came home with the Roundhouse and Brewster. So now I need to integrate that into the track planning – good thing it was now vs. 2 weeks when I’d have all the track glued down!

The Beach...

On the scenery front, I finished putting down the ‘sand’, and then Polyurathaning that too, so it doesn’t flake off as easy. I also bought a few cans of Minwax Polycrylic – so I think I’ll give the tops a few coats of that in an attempt to protect them from the food and drink that’s surely going to end up on top of this. Maybe I need to build in cup holders? Hmm…

Construction, Part 3

Painting continued today with rapid progress. However, I did make one mistake – the sample size paints from Home Depot, which covered about 25 sq feet on drywall, only covered about 16 sq feet on the MDF. MDF seems to like to suck up that 1st coat of paint. So off to HD to grab a quart, of which I’m now 1/2 through. I’ve finished 2 coats on everything, and 3 coats on the top with the ‘water’.

1st piece of the puzzle - all painted up!

I still need to sand + stain the other parts, but I’ll put the 3rd coat on them tomorrow. Chapters shows that my track won’t arrive until Oct 11th, so I’ve got lots of time to finish the paint + stain, and then final assembly of the pieces. Next up, the 4′ bridge piece. Part of me wants to scratch build it from balsa wood, but the realist in me suspects that’ll last all of 2 minutes before one of the boys breaks it. I suppose steel would be a good choice, and then I’d have an excuse to get lots of new tools…
