Adding search functionality

Posted September 19, 2013 By landisv1

I finally got around to adding search functionality to this blog, for whatever it’s worth.  I think my categorization makes it fairly simple, but there are probably a few benefits from having it on the site – so hopefully you find it helpful.  I ended up using the method documented here and changing my permalink settings… which I hope I don’t end up regretting.  Definitely still have some clean-up to do, but it’s a start and got me the information I needed at least.

Might have to give this a try.

Your own Dynamic DNS in 3 steps | The Nexus

Posted September 16, 2013 By Landis V

http://nexus.zteo.com/blog/your-own-dynamic-dns-in-3-steps/

Interesting idea, perhaps provides a little bit of added flexibility (and reduced cost) compared to Dyn, though I don’t have any complaints about Dyn at this point.  Also review the DDNS and TSIG articles on Wikipedia as well as RFC2136.  Still thinking that perhaps a hybrid HTTPS method; would allow any web server one had available to potentially be able to serve as a receiver for the updates as long as it had at least enough outbound access to give the information to the BIND server, allowing for possibly a bit more obscurity in the update path; also wouldn’t require that whatever host received the update information not have BIND running (i.e., perhaps a web host) as long as it could establish an outbound communication to the BIND server – or write to some file that the BIND server could retrieve.

Interesting question therefrom – short of a VPS, is it possible to use client-side certificates to identify a client to a webserver?  How about self-signed client certificates?

stack your knowledge: IOS IPsec ezVPN server – part I

Posted September 11, 2013 By Landis V

http://staystack.blogspot.com/2013/04/ios-ipsec-ezvpn-server.html

Helpful article, though I wasn’t working with ezVPN.  The ‘reverse-route’ component was a critical one I was missing, though I’m pretty sure it’s still not going to get me where I need to go.   I’m attempting to get a software VPN client configuration to work with a router that’s also performing IPSec VPN in conjunction with VRF and zone firewall.  We’ve already encountered one show-stopping bug between ZBF/ZFW and NAT virtual interface (NVI), and I’m fairly sure about five steps down the road from reverse route injection that we’ve encountered yet another bug that will prove fatal in this endeavor as well.

 

No matter I guess.  Probably need to get this lab back to a more standard configuration in any case.  If you do happen to encounter a problem with ZFW, VRF, and software VPN client I’d love to hear about it in the comments.  Always nice to know you’re not the only one Cisco’s feature sets are leaving up a creek. If I get time, I’ll try to post a more detailed configuration example and steps that lead me to this conclusion.  I still haven’t completely disproven it, and haven’t run any debugs at all yet, so there’s still a slim possibility it could actually function.

Notching, Boring, and Conduit

Posted September 8, 2013 By Landis V

http://www.familyhandyman.com/walls/drilling-holes-notching-and-boring-holes-in-wood-studs/view-all

I recently subscribed to Family Handyman. There’s an endless supply of useful things to do and build in there.  Ran across this page on their site while I was searching for information on drilling and/or notching studs in prebuilt walls.  While it didn’t dig into finished walls, the reference for code/recommendations on the allowed size of bores and notches is great.

This reference to sizing for plastic conduit bushings and EMT size is handy in combination with the above.  Didn’t realize that neither dimension of EMT actually corresponded to its true size.

I also ran across that link to a list of “Electricians’ Tricks of the Trade” that has some helpful ideas for a lot of handywork and cabling projects.

Mower reference pages

Posted September 1, 2013 By Landis V

Pages referenced while repairing Sabre lawnmower.  Safety switches have been removed and wiring reassembled and functional – can get the tractor to run for a few seconds by spraying carb cleaner in the air intake, but otherwise seems to be starving for fuel.  Confirmed that there is power to the fuel solenoid when keyswitch is in the ‘on’ position.  Interesting that when I pull the hose from the fuel bowl and then put it back on, it seems like it floods the carb for a few seconds (but I still wasn’t able to get it to start).
