SABnzbd not reporting refusal by newsserver because of missing authentication

Post by sander »

As reported on Aug 11 in the thread "Free Newsservers", it seems SABnzbd does not report any useful warning if SABnzbd is not let in by the newsserver because of lacking authentication.

Proof: use newsreader2.eweka.nl as newsserver without username/password, and start a download. SABnzbd will just show Connections, with no warnings at all. Only very seldom you will see a "time-out message". That's it.

I suppose this is a bug.


Code: Select all

Connections

I guess SABnzbd should watch out for something like "480 Authentication required for command".

Code: Select all

sander@fujitsu:~$ telnet newsreader2.eweka.nl nntp

An open server does not say 480, but 211:
