Why Subject lines have squat to do with message content.

Guys I am not a moderator, owner or anything else... just a quickly becoming disinterested Coordinator in this group. 1 Reason the thread topics are out of whack. Take this one.. below titled (Verifying the Identities of IP Coordinators,)yet contains only discussions about DNS. It is no longer about identities, of IP Coordinator yet it goes on and on and on about DNS under a misleading Subject line. Then there is the THREAD more correctly titled Dynamic Addresses. How is anyone following both of these and making sense out of them. ? I really do not care what we talk about.. But I personally like being able to pick and choose what I read about.. without having to fish every message. When we are talking about orangutans, under a title of Planets from Space.. Sure is miss leading.. Just todays gripe.. Carry on I am sure nothing will change. Also remember to... > (Please trim inclusions from previous messages) 73 Jerry N9LYA

My guess would be that it's not a DNS server load issue but more of an administrative / architecture issue. If stale/abandoned entries are not purged, it makes the task of design and coordination a tad more difficult since new hosts/networks have to work around the already assigned ones.

However to answer your question Authorized users can change the DNS data there is a format needed to be sent in the email that the robot know to inter-prate something such as : <host name > <add or delete> <what kind of record should it be (MX A etc)> <Ip adress> you send each host as a single line and you can more then one line Since the robot have a format checking mechanism you dont have to be a DNS expert in order to add or delete hosts specially if you want only to add host name and not complex things such as MX records or CNAME Regards Ronen - 4z4zq http://www.ronen.org ---------------------------------------------------------------------------- ------------------------------------------ 1. What information must a coordinator send to the ampr.org DNS to create/modify a listing? 2. Is there a standard entry format for the information a coordinator sends in, or is it parsed by hand? 4.

We could > re-invent DHCP... I am firmly against that. Contrary to the Internet as it is now, we are not a collection of transient users that only use a couple of centralized services, but we are all peers that should be able to both use and offer services and make connections in all directions. That is what makes us different from ordinary internet users, and using dynamic or even translated addresses kills all that and makes the whole AMPRnet superfluous. Rob

While using LOTW certificates is quite ingenious, I think the whole process to extract the keys will be a big hangup for the less technical folks. It really needs to be as easy as possible, like how you can use you facebook login (oauth token) to log into other sites. Basically it your ARRL login should work like that, so you can login to the ampr portal, qrz, etc.

When someone applies for an address I need to know where they are located, if applicable to which access point they want to link, if they want a single address or a subnet, what size of subnet they need, a motivation when that is larger than the default /28, etc. Once I have that information I look at the already assigned addresses, and assign them one that fits. (there is a different area in each subnet where single addresses and subnets are allocated) Sure it could all be catered for in input forms, but the amprnet portal currently doesn't, and upgrades to its functionality appear to occur only very infrequently. I don't think it is worthwile to spec out everything and have someone spend time on implementing it, only to find ourselves locked into that system which may not be optimal once some decision is made to handle things differently. Furthermore, many applicants really need some guidance and make requests that are incomplete or not justified (e.g. request allocation of a /22 network for a single station). The semi-automatic mechanism appears to work well and makes it easy to ask for more information. Rob

Portal volunteers [was: Verifying the identities of IP coordinators]

This isn't completely true. You can grep the archives for "I'll be happy to help with the programming" to find at least one offer. Alternatively, my opinion is that Chris would get more help if the project were open sourced. Now instead of recruiting volunteers, he will have contributors. This allows for a lot more flexibility. For example, a ham in one part of the world is stuck at home on a rainy weekend is setting up an AMPR system and encounters a bug. Meanwhile, Chris is enjoying a weekend away from the computer in a part of the world with more favorable weather. With an open source project, the first ham can dig around for the bug and send Chris a patch without any pre-approval. When Chris returns, he can vet the patch before applying it to the SVN [or whatever technology] repo. This significantly lowers the bar for volunteers and administration. If the portal is open sourced, expect a patch from me within the first week. Tom KD7LXL

Re: [44net] Verifying the identities of IP coordinators

Re-validating on a regular/annual basis should be for everyone not just coordinators and gateway ops. It keeps contact information current and could also confirm if they wish to keep their netblock allocation. Think of it as a subtle reminder to maybe get back on board with something they may have put off. : And allows address space to be returned to the pool, and any associated DNS entries in that address space to be removed as well as any associated gateways. I think I might have been the first to ask of the portal project was going to be open source. My thoughts at the time was it seemed like a number of regional BGP connected chucks where breaking off and I figured they may also want to implement a user end kind of portal. If there are some security by obscurity concerns in its design, then we just need a github type of thing hosted on 44net so that non hams are restricted from viewing and submitting to the project. And even if that doesn't happen for the portal, I think a ham only github type of thing might be a good idea. A number of ham projects get picked up and spun by commercial folks. The earliest example is probably Phil Karn's NOS code. And now a present day example would be about non licensed folks getting access to modified atheros drivers or the CS7000 firmware, etc.
