We are also using a pppoe link outsides, and i can do a ping in parallel, which is working continously, so the tun0 stays online. My theorie is, that he keeps the sockets open in state "TIME_WAIT", and this takes too long for the fast nmap scans. cheers Kai > pilax@freesurf.fr wrote: > > sendto in send_tcp_raw: sendto(3, packet, 40, 0, X.X.X.X, 16) => No buffer > > space available > > Your interface is down.
