  • Network issues at home – the last 36 hours

    Wow. Just. Wow.
    I am spent.
    What a mess…..

    I have proof. I can show you the trend line on groov. I was in church.
    There is no way I had anything to do with it. Nothing!

    Let me back up a little…… Friday afternoon, I put the IP cop in.
    Wrote the last blog. (No idea why it did not publish then, but it was probably me – I schedule a lot of my blogs). Had Friday night dinner with the family thinking it was all behind me.
    Saturday morning. All was right in the bald geeks network.
    Church. Streamed the service and it went smooth.
    After church spent some time with Terry.
    After dinner tried to visit my website….. Nothing…. Whaaaaaa.
    Did some little digging. All outbound connections were fine. All inbound that went to my IP address worked, but anything that went to thebaldgeek.net was getting rejected.
    Doing a ping of my URL worked and showed the correct IP address.
    As such, some of my aircraft tracking stuff was working, some wasn’t.

    Thinking it was a caching issue, I got an old laptop out that had not been used for at least a week, tried to get it on the network……
    IPcop would not give it an IP address to get it on the network.
    Link light, but no way I could get it to pick up an IP address and gateway.
    It was around 9:30pm by this stage.
    Rebooted IPcop for the 3rd time.
    Nothing.

    By 10:30pm I give up. My site is down. Had been for many hours (it stopped working around 11:50ish am – like I said, while I was ‘in’ church)…. and I have no idea why or how to fix it.
    I thought about putting the edge router back on, but as I said, I was spent.

    Went to bed.
    Did not sleep much.
    Got up around 4am.
    First thing in the morning as usual, took my blood pressure, it came up in big red numbers for the first time ever… waited a few minutes, took it again. Better, not good. Gave it a few more minutes, and got my highest reading (128 over 84) ever.
    Went for a run (it’s my thinking time).
    Came back and did some reading….

    There were plenty of people that said ‘why don’t you just put in the same router as you had in the first place?’… Two main reasons, it ran hot. Really hot. (This is why they have been failing for others, and probably was the cause for mine to fail).
    The other reason is because it only allowed 32 port forward rules and 32 static IP address reservations. Both limits I bumped up against often.

    Asus’s second latest router, the RT-AC3100 solved the heat issue and in my Googling found that there was some third party ‘WRT’ like firmware for it that removed both of the limits (and added some sweet traffic logging). It also added OpenVPN (as well as the stock PPTP VPN option).

    2-22-2016 9-19-10 AM

    So, that was that then.
    I went down to BestBuy and got one.
    Once I got back, about 20 min later I was up and running. 2-3 hours latter, I had things dialed in pretty sweet.

    Given that IPcop ran fine for some 14-18 hours before it fell over, I am not counting my chooks just yet…. But, I am hopeful.
    I have a VOIP phone, I can skype and my RSS feed is now working again. (Another weird thing that stopped working a few routers back).

    Freddy wanted to know why I did not just get this router last Sunday……

    So, in case you are like my wife and have been keeping track. A total of five (yes FIVE) routers have been abused the past week.

    I had no idea how much I depended on my network to do my job. I had no idea how fragile it was. I had zero clue how hard it would be to get it setup the way I needed.

    I am spent. But we seem to be back up and running.


  • Google Project Sunroof

    This one is pretty interesting if you are into solar (or are thinking about getting it).

    Google are rolling out a website that shows the amount of sun that YOUR roof will get.

    https://www.google.com/get/sunroof#p=0

    It is very personal and as such does not cover every city in the world (yet).
    I actually heard about it about a year back, signed up for it and then had to wait so long that I forgot….. Got an email out of the blue a short while ago, Temecula is now covered. Cool.

    The deal is that they will run the numbers and tell you how much solar your location can expect.
    The really cool thing is that they also do some math on the visuals of your roof, so you can see shade and which parts of your roof get the most sun.
    Here is an example of our street.

    google sunroof

    From this image, I can see that were I currently have my solar panels located is THE WORST possible location I could put them. Sweet! (Or not).

    From there, they then offer details of people that service your area with respect to solar.
    (I’m sure this is where they make money, hooking up customers and businesses).

    Not sure how long it will take them to get downunder, but, check it out, its pretty interesting if only from the aspect of big data.


  • Network issues at home – A new hope

    My Aussies mates are great.
    32 emails and a solid phone call latter and they almost have me sorted… well, ok, my network sorted….
    Dan and Gary really were a huge help in helping me see through the fog and see my options and a way forward in a much better light.

    Long story short, we ended up modifying a small computer, installing Linux on it with a software package called IPcop.
    At this stage, we have it in and running things. There is some mopping up to get the last of the control devices readdressed, but the point is, things are back up and running.

    There are a few quirks with the new router software. For example, a lot of the daily tests that I do with networking equipment and services are on non-standard port numbers, this means in the new software, I have to first make a ‘service’ for that port number, then I can open the firewall for it and do the port forward. It is surprising how annoying it is. I am still trying to find a way to label the service so that it makes sense, is quick and easy for me to find and makes it easier to read my firewall rules. (You can not rename your services once they are in use, so it has been a drag getting things working).

    The wifi is also a work in progress. The new router does not include wifi which was deliberate. I was not happy with the wifi for the past, well, 5+ years, the whole time we have been in this house it has been hit and miss with the coverage and speeds, so it has been on my to-do list to fix for that whole time… In the past it has been tied to my main router, so was hard to get interested about fixing it, but now that it is totally separate, I am actually excited about fixing it… AND since the router was free, I hope I can use a bit of the budget for that on wifi access points.

    Backing up the network is another issues I wanted to address. If it crashes (or breaks) again, I DO NOT (can not) go another week like the past one…… I need a solid disaster recover plan in place to get the network back to where it was. The new software and hardware should offer this, and it is something I will be testing once the dust settles.

    Lastly, I do not have as much visibility of my network traffic as I hoped. A lot of my testing can sometimes get out of control…. I can have a service spew network traffic loud, far and wide and it has been hard to see that in the past, I wanted to address this in anything I implemented, so to that end, I hope to find some plugins or tools to help me see the invisible packets of traffic on the network (hint, TRON).

    Anyway, we are not totally out of the woods, but the fog, doom and gloom has lifted and I can breath (and sleep) again.

    Half a planet away, and my mates are still digging me out of holes.
    Auwsom.


  • Pro Tip. Don’t turn off 2 factor auth if you have it.

    I really don’t get why anyone would tell people to water down their computer security.

    http://arstechnica.com/tech-policy/2015/12/australian-government-tells-citizens-to-turn-off-two-factor-authentication/

    The Australian government has repeatedly called for citizens to turn off two-factor authentication (2FA) at its main digital government portal, myGov. The portal’s Twitter account has recently been updated several times with cute pictures encouraging holidaymakers to “turn off your myGov security codes”

    The portal is the place where Australian citizens can use and manage a number of governmental services, including health insurance, tax payments, and child support. In case of myGov, two-factor authentication is implemented by sending users text messages that contain one-time codes to complement their usual passwords.

    The point is that it is unlikely that someone will have both your username/passwords for the site AND your mobile phone.
    This is what makes two factor so good. It makes things really really hard for someone to bust into your account by just guessing things, or even doing some social hacking…. They might get some info, but they still need physical access to your mobile phone to get the code.

    Yeah, Ok, if and that’s a pretty big if, you are traveling over seas, you might have to stop and think about things, but to just go out and tell everyone to turn it off is just nuts.

    If you have any websites you visit offer two factor. Take it up.
    Do not listen to these guys. Do not turn it off.
    Plain and simple.


  • Network issues at home – cant phone home

    From almost the first week we moved to The States, every Tuesday night I have called my Dad. We used the VOIP (phone over Internet) phone since it was registered in Ballarat, it is a local call for me.
    Keep in mind that we have been here seven point something years, so it has been a pretty regular occurrence…..

    Last night, pretty sure for the first time ever, I could not phone home because of technical difficulties.
    Seems that the new (very very temporary) router is blocking the SIP protocol that is required for my phone to reach the server in Ballarat.

    Here is a screenshot of my network as it currently stands….
    network down

    Two things, yeah, I have a software package that monitors all the devices on my network for me…. What? You don’t?… wow… weird man….
    Second thing, red is bad, green is good… The current state of my network is a shambles.

    The current plan is that my mate Dan is going to rescue my sorry mess.
    We are looking at putting a Mikrotik router into play…. bit of a learning curve, but I think the flexibility and tools it offers is going to set me up for a very long time and give me the features that I have been wanting for ages.

    In time, I should even be able to phone home. Sorry I missed the call Dad, but we are working on it as hard and as fast as we can….
