I have a friend running his and my DNS on a server at his house with two DSL feeds for good measure, one is primary DNS for our domains, second one is published as the secondary. *nod* I'd worry about DSL circuits and stability for DNS. But it will probably work > 98% of the time. If you're comfortable with it, more power to you. I would likely do something more like I'm doing now, run the master name server (MNAME field in the SOA record) on the DSL and have somebody else with a more robust connection (DSL had issues where I'm from) do a slave zone transfer and be the listed Name Servers (NS records) that the world talks to. I actually do that now with my VPS being the MNAME server and my VPS provider doing slave zone transfers off of me. Note how the registrar is not part of that mix. ;-) The biggest thing to watch for is the lax rules for transfering domains. There was a problem with that, but most registrars allow locks now that impede the movement of domains w/o a bit of work. That sounds like you're talking about moving domains between registrars, which is decidedly different than and independent of where DNS is hosted. Admittedly the registrar has to point (delegate) to the DNS hosting provider. But it's fairly easy to move domains between registrars without even logging into a portal at the DNS host. Used to take a couple of emails to highjack a domain, as there wasn't even a notification to verify that the transfer process email was requested by the owner. Ya. Registrars have had some deficiencies over the years. I think they are getting better. You are strongly encouraged to use a third party "professional" DNS service, but it only really need to be up reliably. ~whistling~ … ~quiet~ … I'm sorry, did you say something? No. Never mind. I'll go back to what I was doing. … ~whistling~ I mean that as a joke. I let a LOT of what companies that are trying to sell to me go in one ear, sanity check it, and then go out the other ear. I'm of the opinion that a static IP is the biggest requirement for /most/ DNS service. I.e. somewhere to have the registrar delegate the DNS to. Beyond that, I'm happy to delegate sub-domains to people on dynamic IPs if they want them. It's possible to put DNS a LOT of places that don't qualify as "Best Practice". Most of them will work most of the time. We have the dual providers for the node my friend runs, as we know from the phone companies and providers that though the DNS is over the same 12 pair wire into his house (another trick), the CO actually has the DNS switches on different racks and UPS's. Which isn't a bad precaution. That's probably okay for most things. But it's still subject to Backhoe Bob and the fade that he can induce. That's why I have my master that I can do anything and everything I want to, and outsource to slave secondaries. Linode, my VPS provider, has five different DNS servers that (I belie) are geographically diverse. It will be quite a bit harder to take out all five of their DNS servers. Plus, I don't have to pay for connectivity in five different locations. ;-) I'm curious, you said DSL. But that could be anything from 1.5 Mbps ADSL to SDSL to VDSL. Each of which have different capabilities and SLAs. Other than the backhoe fade taking out both connections at the same time, higher quality DSL with SLAs is probably okay to do. I think the official recommendation for big (think root level) DNS servers is to have each server in a different network, where network is defined as /24 (or larger), preferably under different ASNs. But that's not a /requirement/, especially for smaller DNS operators. thanks You're welcome. -- Grant. . . . unix || die

That's what I have suggested him, but he wanted to test his algorithm on this project, and all I can say is wow :-) The "ordinary" way of reading the Executable ROS contents is to put the machine into single-step mode and press RESTART. This effectively enables access to the ROS contents via the address and data bus on the backplane. You then force the upper address bits from outside (it's an open-collector bus), i.e. in increments of 1024 bytes, and sample the 1024 byte block from the data bus along with the lowest 10 address bits. The caveat is that the display controller will be enabled and permanently accesses the first 1024 bytes of the memory for the screen display. I had read the contents of my 5110 Executable ROS modules just like Tom, but I used normal image post-processing and OCR - all that many years ago and therefore with a lot of manual work involved ;-) But that was successful at the end and lead to a functional 5110 emulator.

Re: Recovering the ROM of an IBM 5100 using OCR (among other things)
I love the walk through things. I'd clearly have found a wired, digital, method of doing it ( printer port or such ). I had a similar problem. I was recovering 4004 code printed out with what looked like a ASR33 print. I did it manually. On looking at the data, I suspect the platen had ruts as the pdf image had faded columns. Most of the letter text was for labels or comments. These were easy to patch things like P and F or E and B. The harder one was C and 0. The program mostly used decimal but when specifying 4004 registers data, it used for the SRC instructions or nibble data, they were in HEX. C and 0 were used quite often. I was able to find what I believe were all the errors by emulating the 4004 code and finding errors in the operation. I recall finding the last error that was in the display output routine ( related to placement of the decimal point ). I'd put "00" where the original code was "CC". 99+% of the "CC" in the rest of the code were really "00". Most mixed were either "0C" or "C0" so it seemed justified to be "00". It was the only location that "CC" existed in the entire code. Even the best OCR could not have done as well as a human that understood what the intent was. Understanding the redundancy in the code is a valuable attribute that a human has that would be difficult for a learning program to pick up. I've used similar thinking to fix cassette tape data that had dropouts. It was BASIC code, although tokenized. The redundancy of the good parts of the data made filling in the missing parts easier.

Re: Recovering the ROM of an IBM 5100 using OCR (among other things)
In the early days of cyber crime (it was called “computer crime” back in the 1980s), fraudsters would purchase an aerosol spray with tiny metal particles in it (I forget what the specific valid use case was, but it was legitimate), and apply the spray to the mag stripe on the back of credit cards, then visually read out the bits with a magnifier. 1s and 0s oriented the tiny metal bits orthogonally, and this could be observed. Then they would program card blanks with the recovered mag stripe data. Mag stripe readers were expensive and hard to acquire in those days, so this was the chosen method of recovering track data from credit cards. I was a police detective investigating “Stone Age”, i.e. pre-Internet cyber crime in that era, and saw this for myself by actually spraying a card and then reading out its data.

So unless they are planning on offering refunds I expect my service to continue for a few more years. By then the landscape will have changed again. One issue with the other providers is the lack of integration - at least for me. On most of the gear I use the DynDns service is a in HW option. So I don't have to run clients on my clients to update IPs. -Ali

There has not been a free option for seveal years. I switched to the paid version. But now it seems that having been eaten by Oracle, it is now being digested.

Re: R: OT: the end of Dyn DNS
I have my DNS records hosted at gandi.net, who are also my registrar. I have been using for the last 10-15 years with no problems. I have heard the that you shouldn't have your register be the same company as your DNS provider, and I intend to revise this proposition. If the argument still holds then I would keep gandi.net as my registrar look for a different DNS service. I tried a lot of third-party DNS services for about five years before settling on gandi.net. Some were very expensive and some were not. There was no difference in the quality of service and quality of support between the expensive and inexpensive ones, but I never had any luck with the free ones.

I use no-ip, the free version. And it's not particularly pushing the paid option aside just suggesting it on renewal. There's an email I don't even remember every how many months, requiring 2 clicks to keep the free subscription active, and that's all -Messaggio originale- Da: cctalk [mailto:cctalk-boun...@classiccmp.org] Per conto di Mark Linimon via cctalk Inviato: giovedì 27 giugno 2019 03:49 A: Charles Dickman; General Discussion: On-Topic and Off-Topic Posts Oggetto: Re: OT: the end of Dyn DNS On Wed, Jun 26, 2019 at 09:36:30PM -0400, Charles Dickman via cctalk wrote: > Now that Dyn has been absorbed by Oracle I need a new DNS service for my > vanity domain. I welcome suggestions for a replacement provider. I was just investigating free alternatives myself earlier today. (I have not yet come up with a conclusion.) I currently use the free he.net ivp6 tunnel so I may already be set up for their free DNS service, but I don't know yet. (I can recommend the tunnel.) Most of the articles on the web mention: Dynu, afraid.org, Duck DNS, and No-IP among a few others. The latter sounds like they are really pushing their paid model, though. (OTOH each of the above has paid tiers for all but the most basic users.) If you are using pfSense like I am, they already support: https://docs.netgate.com/pfsense/en/latest/dns/dynamic-dns.html I would be happy to hear of actual experiences with any of these. mcl
