Description Stefan Helfrich 2013-01-22 17:29:53 CST 
When trying to initialize or upload to an update-site via SSH, entering the correct pass phrase three times raises an error and aborts the process.

com.jcraft.jsch.JSchException: Auth cancel
	at com.jcraft.jsch.Session.connect(Session.java:451)
	at com.jcraft.jsch.Session.connect(Session.java:150)

	at imagej.updater.gui.UpdaterFrame.upload(UpdaterFrame.java:828)
	at imagej.updater.gui.UpdaterFrame$7$1.run(UpdaterFrame.java:343)


I have kept the settings exactly the same and have removed the pass phrase from the key. Therefore, I am not asked for the phrase anymore and the connection can be established and the upload can be completed.

Ubuntu 12.04 (64bit)

It does not ask for the pass phrase for the key, but instead for the password.

Pass-phrase-protected keys are unsupported for now, patches welcome! (See https://github.com/imagej/imagej/blob/master/core/updater/ssh/src/main/java/imagej/updater/ssh/SSHSessionCreator.java#L82 for details)

I have proposed a fork on the imagej github project. This seems to have been a problem with JSch 0.1.42. Using 0.1.49 fixes the problem, however I haven't tested compatibility with older Java versions. Looking at the change-log I couldn't find any information about this.

Thank you! I just merged and pushed this. It will be part of the next beta version of ImageJ2!
