Nut upsdev - Jan 2012 - A patch to add a command to get client information

Hello!!

I'm a sysadmin at La Laguna University in Spain. We are using NUT to manage
our UPS with great success, but we miss a feature and we would like to send
this patch to you.

If you apply this patch running upsd -c info you'll get information about
client connections in syslog. This is very simple and helpfull if you have
hundreds of servers connected to the same upsd.

Thank you for your nice work!!

indeed, it's an interesting feature.

after thinking a bit, here is a potentially more useful approach, that
would complement "GET NUMLOGINS":
Add a new "LIST CLIENT" command to the network protocol [1]

Form:

    LIST CLIENT [device_name]

Response:

    BEGIN LIST CLIENT
    CLIENT <client IP address> <device name>
    ...
    END LIST CLIENT

    BEGIN LIST CLIENT
    CLIENT ::1 ups1
    CLIENT ::1 ups2
    CLIENT 166.99.250.2 ups2
    END LIST CLIENT

This would be completed by a new upsc option ("-c" for example) to get
this list.

Note that this is more an RFC, since it's just a base idea (I've not
checked all details).
So feedback and comments welcome...
Would the above suits your needs Ren? Martin?
