VCL: warnings for reservation timeout?
We've noticed that when a reservation times out, the system drops its
public NIC off the wire without any warning. I can imagine some pretty
unhappy users who lose track of time and lose work when they get cut
off. Has anyone engineered some kind of warning notice for this?
Thanks.

It just occurred to me to ask: if the popups aren't occurring, where
would we look for an indication of a problem? vcld log on the
management node? Any telltale strings we might grep for?

Hi Josh.
I found the e-mail setting. I expect that won't do much good when
people are using a machine without an e-mail client.
No, we aren't getting any popup notification. But knowing that we
should be at least gives us something to investigate.

Michael,
For users with "Send email notifications about reservations" set to
Enabled under User Preferences->General Preferences, the warning
emails should be sent out if the user has an email address set. Email
addresses are generally populated via ldap. If you are not populating
email addresses via ldap, the notifications will not go out.
There should also be a popup warning at 10 and 5 minutes within the
session on the reserved node. If you are not getting a popup warning,
there is a problem that needs to be looked in to.

There is a warning, or a couple of them - from the FAQ.
"You will receive warnings at 10 minutes and 5 minutes before your
reservation expires."
IIRC, you can choose the type of notification, e.g. e-mail or ... I
think you need to set this in User Preferences (which I don't remember
how to access. :-)
