Oh sad.. The content at http://radio4all.net/ has all dissapeard since yesterday..It's not a site problem, it's just all been removed. Now it's called "Recordist Group" and the entire database of the audio program material is gone.
Gonna miss that link.
Earlier today I downloaded the latest Radio Ecoshock program from radio4all.net, and it worked then.
So just now, upon reading your posting, I checked again and radio4all.net is still coming in, I even hit the refresh button.
But I was advised by a colleague about a month ago that radio4all will be closing because of management and financial difficulties that cannot be overcome.
Soon I will dig out the story that was e-mailed to me giving the background on the situation, it's an interesting story of success and failure.
Yeah.. Just figured out the probelm about 2 minutes ago.. Evidently they have just changed servers and as of the moment the link http://radio4all.net/ wont get you there, but the fuller link http://www.radio4all.net/ does
My bookmarked link which I always accessed the site from was http://radio4all.net/ which has changed to pointing to the 'Recordist Group'... What a difference the www part can sometimes make!
Try the two links and you'll see what I mean, also note that on the working route they have a banner at the top of the page saying
I know I'm taking this subject farther than it has to be, and it's non-part15 related, but this occurence has reminded me of something I use to experience a long time ago when I used to build a lot of websites, and right now, for the time being, this provides a good example, and it's kind of interesting:
If you type radio4all.net or http://radio4all.net in your address bar (or click a link structured as such) either will both go to the 'Recordist Group' webpage.
If you type www.radio4all.net or http://www.radio4all.net in your address bar (or click a link structured as such) either will go to the 'a-infos Radio Project' webpage.
This demonstrates that distinction between the internet and the world wide web.. The internet is the actual domain.
The world wide web (www) is a subdomain, same as are other protocols like for example smpt is with email, etc..
So what? You don't care?.. Yeah, me either really, as long as it works. Nevertheless, it is interesting.
Within another 24 hours or so after all servers are updated all four of the above links will point to the same webpage, and this presentation of example will no longer work.. because the examples provided in this post is as it were also a subdomain of the internet... sorta kinda.
Message to Rich Powers:
I am glad you posted here about radio4all.net and I would suggest that this IS a topic of great interest to part 15.
Mainly, a lot of radio stations download programs from radio4all, and maybe some upload their programs there.
Also, many part 15 stations have websites, domains, sub-domains, hard-drives and all the same parts and plugs as the radio4all servers.
By the way, how easy is it to start a sub-domain? We could make our call letters a sub-domain.
Ok - this is actually what I do for a living, and while I never claim to be expert at anything, I do have some understanding of it.
This is the non-network-persons-guide.
There is the concept of REGISTRAR, DNS HOST, SERVER HOST.
Definitions:
TLD: Top Level Domain - this is the .com, .net, .us, etc etc..
DOMAIN NAME: a name you pick + the TLD (example: part15.us)
SUB-DOMAIN: a hostname or virtual hostname prepended to the DOMAIN NAME (example: mlr.part.us - mlr is the SUB-DOMAIN)
REGISTRAR: The place you buy the domain name from. You tell these guys who you use for DNS HOSTING
DNS HOST: This is a simple record keeper that exposes a network service (DNS) to the dirty internet. Typically port 53 TCP and/or UDP.
SERVER HOST: I use this term rather that WEB HOST because you may decide to host something more than WEB pages. You can host WEB, SHOUTCAST, ICECAST, or whatever you like, provided your HOSTING service allows it.
To get a SUB-DOMAIN, the process is to create a DNS record of CNAME (canonical name) or A RECORD (an IP address) with you DNS HOST that points to your HOSTING SERVICE or SERVER. It's that easy.
How DNS works: You attempt to visit a DOMAIN NAME or SUB-DOMAIN, Your application (such as a web browser) asks your default DNS "Who owns this DOMAIN NAME?", then your DNS SERVER asks the ROOT SERVERS "Hey, who owns DOMAIN NAME?", the ROOT SERVERS say "The REGISTRAR is X", then your DNS server says "Hey, DOMAIN NAME DNS SERVER, whats the IP ADDRESS of this DOMAIN NAME?", and that server says "Oh, that belongs over at 000.000.000.000", then your DNS server caches the information for future lookups and will not have to go through this process again. And finally, it tells your application "Here ya go, buddy. Go here." Then you get your webpage. All this at the speed of the slowest contention point in the network.
If you use a hosting provider like HostGator.com (unlimited bandwith, unlimited storage and I am not affiliated with them) than a lot of this is wrapped up in a neat little web interface.
mir, you are not "just this guy," you are just THE guy!
Very nice lesson on how all the parts go together with sub-domains and everything.
Thank you.
As for discussion about Radio4All, I noticed a couple weeks ago they have not been updating the file lists.
I use WGET to automate file downloads. I noticed I wasn't getting updates for PCJ Media programs. A look at Radio4All showed they hadn't updated for a couple weeks.
So, now I have to manually FTP direct from PCJ Media.
