An oddity

Topics about the Beta trials up to Build 3043, the last build by Cumulus's founder Steve Loft. It was by this time way out of Beta but Steve wanted to keep it that way until he made a decision on his and Cumulus's future.

An oddity

Post by Adrian Hudson »

No idea if this is a bug or not but I decided to post this for you to park in your mental multi-story. I closed my weather-pc and webserver down for an hour or so while I replaced my ADSL router. On starting everything up I noticed after a while that no FTP data was getting through. Looking in the diags there were loads of messages similar to this:

uploading realtime.txt to realtime.txt : The requested name is valid, but no data of the requested type was found

To fix it, all I did was end and restart cumulus.

Attached are my MXdiags

That's a DNS error (apparently), it was unable to resolve the name of the ftp server for some reason.

Sometimes computers mystify me. Why should stopping and restarting fix a DNS resolve problem?? Oh well.

(that was a rhetorical question)

Your ISP's DNS servers went down for a period and you were just unlucky?

I always use 2 publically available DNS servers from this list, http://public-dns.tk/nameserver/gb.html.

The chances of 2 different public DNS servers going down at the same time are remote.

Possibly the ftp library only does the lookup (or causes the lookup to be done) when it's first called.

Its an internal web server - no ISP involved.

Interesting thought. Hmmm...
