Comment 21 for bug 159031

While the deeper issues are being worked (thanks folks!) I wonder if it would be a good idea to automatically unmount remotely mounted filesystems when the network goes down, and then remount when it comes up. If so, best practices for doing so would be welcome.

Providing a hint here on how to run network-manager from the command line might help. I notice nmcli and cnetworkmanager mentioned in web pages, but they may not be in ubuntu yet?

FWIW, on my netbook, after a visit to a different wifi network, a few things got hung: emacs (after I tried to open a file on a remote filesystem), evince (no idea why - won't even restart - something in the history perhaps??) and lsof (even with the -b option - huh??)
