SFTP: disconnect on route-suspend
Hello,
I have some routes with SFTP endpoints on consumer and producer side. I
trigger these routes via quartz and suspend them after work is done. The
endpoints keep the SFTP connections open in this case.
I want the SFTP connections to be shut down (close the network connections)
when I suspend the routes. JSCH shall re-login when I restart the routes, I
don't want to keep connections open.
How can I achieve this?
Thanks, mdo.

Our project has similar requirements - in addition to parameterizing
the SFTP connection at runtime, not
just at route declaration-time. I was led to believe that, generally,
consumers can't be parameterized at
runtime, so I made a few attempts at creating my own custom component
to do SFTP with parameters
passed in at runtime, triggered by Quartz cron trigger. This worked,
but didn't get automatically
wrapped in JMX wrappers, plus other clunky issues.
I ended up having the quartz/cron trigger send the parameters to a
custom processor which
creates a route at runtime, starting with an SFTP consumer - plus a
background thread that
defines the poll time duration, after which, the thread stops the
route, then removes it.
This all works for us now, including multiple, concurrent connections
(well, only two simultaneous
tested so far)
You might want to try an approach like that.

I know that stopping the route does shut down the endpoints. But we changed
to suspend/resume a month ago because we noticed that stop/restart leaks
threads in GlassFish. If I did stop the route I would have to remove and
recreate it each time Quartz fires. This would also knock down my whole
approach of initially setting up routes on application startup.
At the moment I'm looking into endpoint options, something like:
serverAliveInterval 900
serverAliveCountMax 0
This idea was inspired by http://serverfault.com/a/450916
But this doesn't seem to work neither. JSCH goes nuts and disconnects right
before logging in and "SSH_MSG_KEXDH_INIT sent" should get logged.
Regards, mdo.

Use stop instead of suspend.
