[hobbit] Monitor user specific procs

[Daniel Bourque]

I'm assuming you're running the hobbit client on the host running the 
tunnel. On the server's hobbit-clients.cfg :

HOST=foo
    PROC="ssh -N -g -L 2022:127.0.0.1:22 -L 15294:10.20.2.11:15294 
-R15294:10.0.2.11:15294 1.2.3.4"

This make sure that the process is running, but gives no assurance that 
all tunnel segments are ok ( I experience that problem often ). So you 
could also add :

    PORT LOCAL=%[.:]15294 STATE=LISTEN "TEXT=foo bar"
    PORT LOCAL=%[.:]2022 STATE=LISTEN "TEXT=foo bar 2"

This makes sure that "-L 2022:127.0.0.1:22" and "-L 
15294:10.20.2.11:15294" are still up.

You can even add net tests for socket 2022 and 15294 by defining them in 
bb-services and having the hobbit server check them against that host.

Hope this helps.
