Subject Re: Net.NNTP: Different behavior using different newsserver
Date Mon, 16 Mar 2009 14:09:40 GMT


after a research and some tcpdumps I tried to use the same commands as
"GrabIT" for receiving the group headers.
I perform these actions (after I already load the groups successfully)
1.) Disconnect
2.) Connect/Authenticate
3.) Select Newsgroup
4.) Download header

At point (4) the program halts for some seconds and then it stopped with
"Connection closed without indication." This occurs in line

"DotTerminatedMessageReader reader =
(DotTerminatedMessageReader)client.retrieveArticleInfo(rangeFrom, rangeTo);

A really strange behaviour, do you see any reasons for this?

Kind regards,
D. Penning
