Script to Monitor Remote System -

[admin]

You can make multiple copies of this script as a resident script with sleep time set to 0. init script should not have any blocking or long-running parts.

Also non-blocking connect should be used and possible errors during receive should be checked:

Code:

if not sock then   sock = require('socket').tcp()   sock:settimeout(1)   res, err = sock:connect('192.168.1.100', 2401)   if not res then     log('connect failed', err)     sock:close()     sock = nil     os.sleep(1)   end end if sock then       res, err = sock:receive('*l')   if res then     -- parse res   elseif err == 'closed' then     log('connection closed')     sock:close()     sock = nil   end end
