Created attachment 155926 [details] Connection attempt hanging When trying to add a remote host for build/debug the ssh connection window just hangs and never prompts me for the password. This only happens on one of my machines (both windows). Machine A is able to connect with no issues. Machine B just hangs. I have detailed the information I have collected with respect to this on the user forum at: https://forums.netbeans.org/topic64208.html Since ssh connections with both putty, and direct with a small java app I have written work without issue, I believe this to be a bug in the IDE. The attached screenshot shows the point at which the connection hangs. The logs that I have posted to the forum post repeat endlessly and clicking cancel has no effect. I have to use the little 'stop' button at the bottom right of the IDE main window to actual cancel the connection attempt.
I guess the connect might be just timed out. You can extend timeot via command-line option -J-Djsch.connection.timeout=N (where N is time in milliseconds) Will this help?

Yep this seems to work, so I guess the only bug is the lack of any feedback to this effect. Probably not a huge priority but a log message would have helped alot here. The ideal solution, for me, would probably be to show this directly int he ssh connection ui, and perhaps allow configuration of the timeout value there but I would defer to what you think is best.
This is also related with issue 257643: if user had UI for timeout, I think he would't escalate issue 257643
