Subject [jira] [Commented] (DIRMINA-944) Server logs 'Connection reset by peer' and sends RST but no disconnect found in packet capture
Date Wed, 15 May 2013 21:59:17 GMT

    [ https://issues.apache.org/jira/browse/DIRMINA-944?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13658878#comment-13658878
] 

James commented on DIRMINA-944:
-------------------------------

Mina is serverside, providing FTP over SSL.  The peer client is Cyberduck.  Correct version
is actually 2.0.5 (will update), and there is a fix listed in 2.0.7 that might apply (related
to when SSL negotation occurs).

> Server is logging an exception with 'Connection reset by peer'.  This is intermittant;
usually a second connection attempt will work.  However, in packet capture there is no difference
between the two examples up to the point where the server sends an RST packet - there is definitely
no reset from the client side.
> This happens right after the server sends the SSL hello, when the next step should be
key negotation.
> I'm not sure what the next steps are to troubleshoot this or get more debug information.
