-----------------------------------------
Comment on FTPSERVER-150 by David Latorre:
The provided method to find if the connection is secure:
public boolean isSecure() {
return ioSession.getFilterChain().contains("sslSessionFilter");
}
is not sufficient as the SSLFilter in implicit-ssl mode is called "sslFilter"
rather than "sslSessionFilter".
> Provide convenience methods for checking is the control and data sockets are
> secure

> Key: FTPSERVER-149
> URL: https://issues.apache.org/jira/browse/FTPSERVER-149
> Project: FtpServer
> Issue Type: Improvement
> Affects Versions: 1.0-M2
> Reporter: Niklas Gustavsson
> Assignee: Niklas Gustavsson
> Fix For: 1.0-M3
>
>
> Checking if the data and control sockets are secure (running over SSL/TLS)
> from a Ftplet is quite intricate and depends on knowledge of the internal
> implementation in FtpServer. We should make this simple. Suggestion by Jeroen
> Cranendonk
> I've cobbled together some code which should give an idea of what I'm trying
> to achieve, haven't tested it yet though. And I do realize this probably
> breaks your design in all kinds of ways :)
> Firstly, I've added the following to FtpSessionImpl:
> public boolean isDataConnectionSecure() {
> return ioSession.getDataConnection().isSecure();
> }
> public boolean isSecure() {
> return
> ioSession.getFilterChain().contains("sslSessionFilter");
> }
> public void write(final Object message) {
> ioSession.write(message);
> }
> And then my Ftplet looks like this (and it probably won't compile unless
> it's against the full ftpserver code):
> public class MyFtplet extends DefaultFtplet implements Ftplet {
> @Override
> public FtpletEnum onUploadStart(final FtpSession session, final
> FtpRequest request) throws FtpException,
> IOException {
> return this.onLimitedStart(session, request);
> }
> private FtpletEnum onLimitedStart(final FtpSession session, final
> FtpRequest request) {
> if (session.isSecure() && session.isDataConnectionSecure())
> {
> return FtpletEnum.RET_DEFAULT;
> }
> session.write(new
> DefaultFtpReply(FtpReply.REPLY_550_REQUESTED_ACTION_NOT_TAKEN,
> "Cannot do this before securing the connection."));
> return FtpletEnum.RET_SKIP;
> }
> }
