In the man page for FreeBSD ping:
-s packetsize Specify the number of data bytes to be sent. The default is 56, which translates into 64 ICMP data bytes when combined with the 8 bytes of ICMP header data. Only the super-user may specify val- ues more than default. This option cannot be used with ping sweeps.
Does anyone know how I can let non-superusers send pings larger then 56? Can I increase the default size, or somehow allow -s to be used by non-root users? I am aware of the security implications, that this could allow users to start a ping flood, so if I can restrict this to allowing only a single (shell-less) user, all the better.
