Hei,

Im trying to connect to a Oracle Database repository via FTP on port 2104, but gets the following error:

2011-02-01 11:14:24,770 [7] ERROR -- Error in connection: 192.168.1.5:4590, acceptclientcallback

Any idea whats causing this?

Thanks for a great ftpclient btw. :-)

Discovered that the repository returned "no-features" at FeatCmd() function with no inital "Features:" or trailing "End"

Did a quickfix to get around the problem:

  string feature_trim = features[0].Trim();
  if (!feature_trim.Equals("no-features"))
  {
        features.RemoveAt(0);
        features.RemoveAt(features.Count - 1);
  }
  else
  features = null;

Thanks for posting this issue.

this is a non-standard behaviour, but being Oracle support for it will be included.

I want to include that my Z/OS (MVS) system also returns the FEAT  without an END so I also receive the OutOfRangeException. I am including the portion of the log that shows the FEAT. Thanks a million for working on this I love your Class Library.
