'Address Not Found' Problem

sheepherder · 12-01-2016, 11:58 AM

John, I have noticed this past week that Lugerforum has been 'unavailable' several times per day. I mentioned this to an administrator who said he had not noticed any 'unavailable' outages.

I have just completed a switch to a new ISP and had chalked it up to ISP server problems (on my end).

I hope your impending upgrades 'cure/improve' my connection problems.

While my own contributions are minimal, the information I take away from the forum and disseminate to others is invaluable.

Thanks for all your time on this project. We all enjoy the forum and appreciate how much has to go on behind the scenes.

no outages for me this last week - well except when the power went out a couple of times, but I doubt that New Hampshire had anything to do with that

John D. · 12-01-2016, 04:30 PM

Hi folks,

My sincerest thanks - and hopefully, all goes "as planned"... And we usually know how that turn out..??!

Also - sheepherder.... Folks in your family pay me lots of money to disconnect you on occasion. Their plan is that you have to pay more attention to them - rather than this site..!

Seriously - my thanks to all...!

Well - you know me, Bill - it's all about "give and take"..

Seriously, my thanks Bill for all you and others have done for this community - and to you specifically, outside this community as well.... You are an incredible person who supports all efforts - both big and small...

Anyway - I was thinking....

I might actually move this forum to a different server (one that is running under a different OS and SSDs - and see what happens?? If I do that, this forum might be down for a bit longer, but - might well be worth the effort?

Anyway - Bill, just simply thank you for all...

Well...Can it get worse???

John D. · 12-01-2016, 09:52 PM

Of course it could be worse.....

Looking on the bright side - you were able to find it to post this "Not Found" image...???

Let's see what happens after this weekend, as I'll be resetting a number of things - including all the routers, circuits and such...

After that - let's see what happens, OK? I find it strange that, on my end - I see absolutely no outages on anything? I'm just wondering if something isn't pointing to your old DNS with your new ISP? Anyway - we'll get it figured out, OK?

It seems if I wait a minute or two and try again, sometimes 3 or 4 times, I finally get through...

Anything is possible...But this is not a new occurrence; I've mentioned it before...and posted that Not Found error msg...

I think the only sure fix is for me to move to Arizona...

John D. · 12-01-2016, 10:01 PM

Move to Arizona??!

Anyway - if it happens again.... I'd LOVE for you to try it on your phone connected to a cellular network - AND NOT a wifi network on your computer.... If it opens using your cellular - I can narrow it down. And connected off of a cell net, I can also capture your IP address, which will help diagnose your connection on wifi (like DNS, traffic conditions, etc..)

Anyway - just tossing that out before having to move your home..?

mrerick · 12-01-2016, 10:04 PM

Rich,

That looks like a DNS name resolution problem.

A likely cause is difficulty getting through to the domain name server that translates the canonical name "forum.luger.com" into the numeric IP address.

On home systems, the access to DNS varies quite a bit. Dialup depends on DNS servers back at the ISP. Most ISPs provide a DNS that is at an address nearby on their network. This IP address is sent to your Cable Modem or DSL Gateway so that devices inside your home can make DNS requests closeby on the network. Some gateway routers cache prior DNS requests, and try and run their own internal DNS server for your home, only referring to the ISP's server when they have to.

Things can go missing on the network, and things can get out of sync.

There is room to configure more than one DNS on your workstation. It's done in the network definitions either on a workstation by workstation basis, or within the configuration of your gateway router itself. If you want to add an alternative that is not on your ISP's network, try "8.8.8.8' which is a Dns server provided by Google.

John D. · 12-01-2016, 10:11 PM

Thanks Marc,

It most probably is the DNS settings which is why I asked him to try it off his cell network - but - it could also be a few other issues as well...

Actually Google truncates the SOA TTL and tries to pull a refresh on the FQDNS (which I host both, btw

) before TTLs, which can create their own issues. A much better option is OpenDNS (208.67.222.222 and 208.67.220.220), FWIW...

John D.

sheepherder · 12-01-2016, 10:12 PM

Heres a post from my phone...mynewisp is through a dsl modem over verizon but not verizon itself...
Marc, this not found has been going on for over a year

John D. · 12-01-2016, 10:17 PM

And did this site open without an issue from this IP/connection?

John D.

John D. · 12-01-2016, 10:29 PM

OK - here is where I am... I looked at the connection logs from my servers to your connection...

Marc is right on - you have a bad config either in your home router or your Windows config (sorry - I don't know which, as you have a firewall in place in your circuit).

So - what's happening - is when you "Open" the site - one of your programmed DNS servers doesn't reply - so it tries to go look for the other... Before THAT can reply, your browser times out - throwing up that error "Not Found". I can't figure out if your ISP has Round-Robin configured correctly, but - there is no hand-off..?

Anyway - you can fix it - but, seeing your Avatar I'm not sure how far you want Marc and I to walk you through it??

John D.

I will add my thanks for all the work you do to keep this Forum running.

John D. · 12-01-2016, 11:01 PM

Ahhh shoot.... My thanks G2...

I've heard from a number of folks this evening, on-line and off - and it always humbles me what an impact this community makes to so many in their daily life. We've been a community for now - about 15 years or more now? Amazing, really.... For that, too?

My sincerest thanks for your post and being a part of this same community...

Then it must be my Windows config...The ISP & modem only came into play last Wednesday...

Yes.

How to fix? (New avatar coming up!)...

BTW: My Windows firewall is OFF, part of the instructions from the new ISP for the DSL modem...
