Apparently my dd-wrt does loopback now

A couple months ago I asked if mosh could be made to work if the mosh-server IP changes when roaming between networks.

Years ago, I used to have routers that did 'loopback', but haven't had ones capable of it for sometime...or so I thought. Though I hadn't really had a major need for it. Except perhaps for mosh.

mosh, MObile SHell, is an ssh replacement that supports roaming and intermittent connectivity. Since I do my IRC using irssi in screen, running all the time on a server at home. This makes staying connected to IRC on my laptop much nicer. I can close my laptop, and later open it and it'll still be connected to my screen session.

The problem was when I came home, I'd be unable to recover the connection correctly and the client goes into an unrecoverable state, so that even if I later use my laptop on an outside network the mosh session won't resume.

But, today I opened my laptop (and I just realized that I didn't do what I had intended to do) and I just minimized the window out the of the way...even though it probably wouldn't recover on Monday at work. But, the dock icon showed that something wanted my attention....probably mosh-client giving up? No. Well, my nick had come up a couple of times yesterday, but it shouldn't have known that....but not really thinking, I switch to the channel. And, it does. I switch around and its working. Wait...it shouldn't be though! :!:

So what changed? I do a tcpdump and see that it is connecting to my WAN IP and getting responses from my WAN IP....'loopback' never worked for me though....

:idea: Perhaps its 'loopback' of port forwards that has never worked....

I had moved irssi from box to dbox a while back. The router has two port forwards set related to this to box, a single port TCP forward and port range UDP forward.

But, because my other router is running stock firmware, it has a limited number of port forwards...so as I was migrating services to cbox (and using nginx to reverse proxy web services on other systems on my home network, where those that use a webserver are using apache, including local services...such as cacti on cbox and nagios on dbox), I decided that I would just make cbox the DMZ host...start running host based firewalls at home, especially on this host (it also uses an IP alias...kind of like how we do hosts behind the BigIP at work &#59;D )

So that means no port forward(s) for my dd-wrt router for WAN to dbox....so I guess the NAT allows 'loopback'ng in this case.

Wonder if the same applies to my other router.

The only problem this causes is that I had plans to replace routers. I actually have a new router to replace the current stock router....though I haven't got anything that really needs to speed upgrade to 802.11ac yet in the room where I using wireless bridging. I also had plans to replace my dd-wrt router, which had started getting unreliable which they seem to do after a while....though it seems to have helped after I deleted old traffic data....

Home Security

After years and years, of saying that I'm going to do it....I finally did it....I got a home security system.

Last couple of years, my HH had been getting particularly disturbing....I thought about doing it then, at least I got my locks rekeyed, which helped on the anxiety level after any particularly disturbing HH.

I had kind of registered the idea that I would definitely get a home security system if I should get a Narcolepsy diagnosis and open me to its particular treatment option.

Well, I got the Cataplexy Dx on May 15th, and the Narcolepsy Dx on July 12th. And, eventually I was to start treatment....July 26th.

After the Cataplexy Dx, I ramped up my intent to get a system. I noticed that AAA offers a discounted package with Lifeshield. So, I opted to get that package for my condo. Along the way, the base package was more than adequate to cover the basic exit/entry points. But, I opt to get a bunch more sensors to provide extra coverage around my medication fridge and medication safe.

It doesn't get me much of a discount off of my condo insurance (since the main structure is covered by a master policy from the HOA) to get any real savings for a security system, it needs to be cellular backed. The cellular gateway option is like $270, so the pay back is there...though it is on my list of addons to get.

But, it sure has helped with piece of mind and my sleeping.

So much for the new tradition...

June 25th came and went...I had a specific thing I wanted to do that day, and bunch of other things I needed to or wanted to do that day....and I think I did get what needed to get done that day....except for one thing. The new tradition.

I forgot to test my smoke detectors. After the July 4th long weekend, I realized I had forgotten...and meant to do it later...perhaps the weekend. But, I never seem to have enough time to get the things I want to do on the weekend (and being summer, I'm working too much...during the week.)

So, it got forgot until this weekend...went screw it, I'm testing them. They all work.

Wonder if for Christmas, I'll give myself some Lithium 9V batteries....supposed to last 10 years...(or supposedy 5x longer than Alkalines in other applications...of course, I'm sure a 9V Alkaline would last longer than 1 year in a smoke detector....but its a safety thing to just replace these sort of things in a proactive way.)

Plus I think 5 years from now I'm going to be looking at getting new smoke detectors....if not sooner. Since the smoke detector is supposed to be replaced after 10 years, I'm assuming of course, that they started the 10 year clock when I first moved in...and that they hadn't been in service too much longer than that.

Guess I've been thinking about the wireless and dual sensor smoke detectors upgrade for a few years now....at the time, they didn't exist. Wireless yes, but one company made ionization and the other made photo electric.... Also there was the question of how to do tell which one detected.

Also one of these days I should crack the whip on getting a CO detector.

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.
