Re: Jailed process listening to broadcast address of host system - possible?
Hello, thanks for your response. Zitat von Fbsd8 : Since your talking about a jail process, you really need to provide details on how you configured the jail and if your using the interface parameter? The jail is configured using the interface parameter, sat to the same IP as the Host. More details I can provide tonight.
