Re: [casper] [ROACH2] tap-start invalid

Hi Marc, On "netstat -ng", it says "netstat: no support for 'AF INET (igmp)' on this system. Can this be due to old version of tcpborphserver ? Regards, Amit On 08-Jun-17 3:54 PM, Marc Welz wrote: > You might be looking in /proc/sys/net, you want to be in /proc/net > > regards > > marc > > > On
