Problema coi DNS? …”laviamoli” (flush) un po’

Varie, , , ,

Ti è mai capitato di andare su siti web per così dire importanti, per cui è impossibile che siano col server down, e che invece ti spiattellano un bel “Server non trovato“?
Potrebbe essere un problema di ordine e pulizia cache legato ai DNS (Domain Name System).

Prima di chiamare il tuo ISP puoi provare a fare pulizia nella relativa cache usando i comandi per il flush dns cache.
Questi i comandi da lanciare col Terminale:

su Mac OS X 10.6 Leopard e successivi:
dscacheutil -flushcache

su Mac OS X 10.5 e precedenti:
lookupd -flushcache 

su Windows una volta era:
ipconfig /flushdns 

 

Buona pulizia …
