Salve.  
Ho uno script che usa druby  
lato client uso:  
proxy = DRbObject.new(nil, “druby://192.168.2.100:20000”)  
Ovviamente quando il server non c’è il client va in errore  
(DRb::DRbConnError)  
vorrei fare in modo che il client non vada in errore ma rimanga in  
attesa, fino a quando il server non è disponibile.

Colgo l’occasione per ringraziare tutti quelli che hanno risposto  
alle mie innumerevoli domande, a volte credo anche un  
pò stupide.\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

def connect  
proxy = DRbObject.new(nil,uri)  
rescue DRb::DRbConnError  
sleep(5)  
puts “Waiting for server…”  
retry  
end

L’aggiunta di un numero massimo di tentativi è  
lasciata come esercizio 😉
