hi..
i'm new at ruby on rails.. first i have a table with a column named status(this column use to store a status of an access point ("online" or "offline") after my application have done pinging the access point)
i use a net-ping library..
how can i update the data in column status "automatically".
Few things come to mind here. I've done this exact app before. I keep my devices in a table. The Rails app just displays the information from the table. A background daemon does the actual monitoring. I get alot more details in my version, including mapping what mac/ip address are on which switch port, and using SNMP to the switch to do discovery of devices.
The moral of this is break you ping into a separate process/task. Then poll yours AP's and update there status with ActiveRecord.
If you need some help, I can certainly give you some pointers.

A brief overview of the docs (and general convention) suggests that PingExternal.new doesn't do a ping, it just creates a pinger object - all you are testing is whether that new object was nil or not.

I've added a blog article of my network scanner. If you need further help let me know.
